this post has been in the passionate making for quite some time now, and now that it has finally found its deserved conclusion, i solemnly assure you that it's wholly worth the wait — i am convinced it will delight many. before we start, however, i need to implant an introductory inkling into your mind. picture this: going on vacation or merely indulging in the persistent, swelling summer heat with henry winter. it would be glorious. now that you're entertaining the notion, let me immerse you in the rather enticing concept of vacation!henry. note that this will be dirty — wickedly so. i haven't been able to stop thinking about this handful of scenarios since the summer started — and it's july. my mind is befogged to say the absolute least.

first of all, he would have to shed and thereby neglect his signature suits — the weather, certainly, would be the only insurmountable obstacle protruding his aesthetic, stylistic, and stoic path. he would simply lose control, unable to do anything about the sweltering heat — and yes, much to his displeasure, perhaps, he would be forced to abandon the multi-layered outfits and resort to much lighter clothing (if any at all). simply imagine him in those old money shorts or light slacks, summer-at-the-hamptons-style, with a loose, billowing, unbuttoned white shirt, sleeves rolled up and all. and sunglasses — god, the sunglasses. he would own the kind that have diopters in them, so he wouldn't have to alternate between his prescription glasses and his shades — he would already possess the best of both worlds. this, consequently, would lead to him rarely ever taking them off. think about that.

i want to imagine you dragging him out to a beach, maybe in maine or massachusetts (having forced him to drive you there in the first place via your convincing charms), or even him taking you on a yacht trip with his family as an eye-pleasing, gorgeous plus-one. or, you could always go on vacation together, just the two of you — he certainly has the money, and, undeniably, the motivation (the entire greek class did, after all, want to go into hiding in argentina, although for a vastly different reason). hell, you could simply go on a hike together as well. i know how uncharacteristic this sounds, but help me god — the notion thereof isn't letting me go. it has clasped a mighty grip around me. i simply cannot resist sharing it.

i need you to picture him in his light, airy outfit, hair disheveled due to the persistent sea wind, and wearing his expensive, dark shades — smelling of a mix of sunscreen, light cologne, and cigarettes. so tall and so ominous and yet so unwound, so absorbant of summer's grace. i would falter. i would never be seen again.

at the beach — and i've already received an ask about this in the past — he would be so unassumingly teasing, so that it would result in ache. actual ache. of course, being henry, he would bring a book, immerse himself in it, and not even consider getting into the water. the most he'd do is step in ankle-deep at your incessant requests and physical urgings. in spite of that, he would still be very indulgent — he would teasingly spread sunscreen all over you upon your merest inquiry, help you adjust your bathing suit and tell you if anything is awry about it for the sake of your modesty, whilst also keeping a curiously daring hand on your spine or your backside as you'd lie next to him. he would be reading attentively, neatly seated on the towel next to you — with you lying on your stomach in the sun and trying to absorb the rays even a little — and yet, one of his free hands would be on you. it could even go as far as his digits lightly grazing your glistening, waxy skin; this constant physical contact would result in various shivers arising all over your body and a certain, straining ache striking in the pit of your stomach.

of course, due to the beach being a public place, you wouldn't have sex there — unless you'd sneak out there at night and then consecutively complain about finding grains of sand everywhere — but that doesn't mean the two of you wouldn't relentlessly tease one another with the obvious allusion thereto. henry would grant you too many touches of an entirely indecent nature to be coincidental, including accidentally dragging his thumbs across your pebbled nipples under the pretense of fixing your bikini top. you, on the other hand, would do anything in your power to get him as riled up as you can — you'd carefully flash him on accident, tease him by exaggerating profusely whilst eating a popsicle, and emphasize swinging your hips as you'd walk back and forth from the shore to the water, fully aware of his observing you closely. all these things considered, i think it goes without saying — you'd end up with your ankles swung over his shoulders and him repeatedly sinking into you in the backseat of his car the very second you will have gotten in and driven out somewhere remote. you'd be gently mewling and crying for him to go deeper, his body so hot and glistening and slippery against yours, with the stale summer heat (commingled with the heat your bodies generate) and the scent of sunscreen permeating the car.

now, to the yacht scenario — admittedly, it's something i've been fantasizing and ruminating and losing my mind about the most. i can just imagine him sitting on the deck, maybe in the far back, with his legs crossed, reading a book with his sunglasses having slid down his nose a little. the wind would mess with his hair and his half-unbuttoned shirt, making him look all the more irresistible, even from afar. you would approach, then, lightly irritated with the fact he still resorts to reading whilst on vacation and in the middle of a picturesque lake, or ocean — disregarding both the breathtaking views and you. depending on whether his parents will be there or not, you'd assess your surroundings, and in the case of the coast being clear, you would muster up all of your courage and dare rip the book from his hands and plant yourself in his lap instead. irked and yet thrilled, he would, of course, welcome you with a firm embrace, flashing you a small grin — a grin that would only hide the merest bit of annoyance. his palm would drift across your thigh, bared by the wind billowing open your lacy beach robe.

"how tactlessly rude of you," he'd quip, trying his best at sounding irked, but unable to conceal his utter interest. exasperated and agitated with his behavior, you'd challenge him, "not as rude as your ignoring me all day." in response, he'd scoff. "i do devote my utmost attention to you during the night, however, don't i?" he'd remark, tilting his head to the side and involuntarily widening his smirk at the small, yet perceptible bite mark upon your collarbone, protruding from the lace. that, undeniably, would shut you right up — similar to the cock being slid down your throat mere minutes later in your shared suite as punishment for you having become so unbearably mouthy and audacious with him. in the end, you'll wind up with a different type of sunscreen all over your face — he'd come on it, hotly and thickly, only to leave you to the joys thereof and retreat to the deck again, flushed and yet centering his focus on his book anew.

whilst on vacation in a different country with it exclusively being the two of you, well — this is where we're offered so much potential. no matter the destination — italy, france, spain, portugal, malta — you would be able to find a way to mix his aesthetic interest with pleasure nevertheless, and constantly. you'd go see a library or an old ruin site in the morning (not after a refreshing round of morning sex before even leaving the hotel room), get impossibly daydrunk at lunch, shamelessly fuck against the window or even on the balcony as a result, go out to encounter more sights in the evening, get even drunker, and conclude the night with one last, gentle round with the windows wide open and the lukewarm night air billowing the curtains the same way your whimpers would swell in the silence.

furthermore, you'd fully indulge in all the wonders of sundress season — specifically the lascivious ones. more often than not, you'd forgo wearing any underwear, and make this noticeable to henry at, seemingly, the most inconvenient of times — at cafés, restaurants, museums, exploration tours, beach walks. this, of course, wouldn't specifically surprise, but nevertheless irritate him. in a mindful, protective manner, he would thenceforth try to keep an eye on your dresses and skirts out of the fear you'd accidentally expose yourself — only to ruthlessly punish you for the unnecessary added worry upon your first step back into the hotel room, without even taking that very garment off. by the end of that vacation, you will probably have been fucked in every outfit you brought. his diary, in latin, would speak of the same.

simply put, the vacation sex would be transcendental; hot, rough, sweaty, messy, desperate. you'd be forced to take multiple showers in a day, thereby going through way more bottles of sunscreen than usual. due to the heat, you simply wouldn't bear having sex at home or in your bed anymore — it would be on any surface proving cool enough instead, such as the kitchen or bathroom counters; desks and tables; against the chilled wall. he would have you flushed and panting, begging and moaning, thrusting into you so roughly and so deeply you'd threaten to disintegrate each and every time anew, simply evaporate in the sweltering air.

aside from that, and this goes without saying, he would pose unspeakable eye candy — too good not to indulge in. and don't get me wrong, i love a good suit, but i also love transferring the dark academia old money style to a much warmer time of year — where the light clothes and sunglasses come into play, and you'd therefore have to put less effort into undressing your counterpart. am i alone in this? simply picturing henry in a more summery outfit — specifically with shades on, which is why i keep referencing them constantly — is mellowing my brain. in addition, the way he would tease... so unassumingly, nonchalantly, imperceptibly — all the while anything but innocently. it makes my throat run dry.

i hope this post marks my stance in regard to the endless appeal of vacation!henry known. it's just such an indulgent notion to nurture. after writing and rereading all this, i find i am in urgent need of a cold shower. simply — god. i crave this, carnally.

Images of the Colorado Rockies taken by photographer Abelardo Morell. He uses a prism to project nearby landscapes onto the ground, which gives the pictures their unique texture. Explanation of his process under the cut:

From his website:

My Tent/Camera is made of a simple light-proof material that wraps around a large adapted tripod that has a plate on top which holds two devices:

1: A 90-degree prism with a lens attached (diopter) This prism acts like a periscope projecting an image of the nearby landscape on the ground below. The focus of the projected image can be adjusted by raising or lowering the height of the tent-Technically this has the effect of changing the focal length of my lens attached to the prism. This makes it possible to achieve discrete focused areas of the image.

2: Next to the prism on top is a digital camera looking straight down and focused on the ground. A picture made this way shows, both the granular details of the ground -stones, grass, dirt cement, etc. plus an added projected vista of the landscape giving the overall result an illusion of a painterly patina that I like. The camera is connected to a laptop computer outside the tent which allows me to compose, see and focus an image with precision.

While I know that technical explanations alone do not fully convey my deeper artistic reasons for exploring reality this way, I think that it is important to outline clearly how this device works and, in a sense, express what I am after. The evolution of photographic technology, since its invention in 1839, has always been tied to the artistic vision and ambition of its practitioners. My aim in this work is to ground myself in new realities.

My pictures show what was there in front and under me. Nothing that was not there has been added. I do believe that the reality of the world seen through various lenses and temperaments surpasses anything that I might want to invent.

[thefrogman]

Thank you for the correction.

I was unconscious for 2 days this week due to a medication reaction and I guess my brain was a little foggy. I got the targets mixed up when I downloaded them.

Just to give people a sense of scale in the difference between the targets...

Here they are adjusted to match scale...

And here is just the center...

Also, here is a series of tweets from a former shooting athlete talking about the equipment from her perspective...

[ Jinga Zhang ]

Just so it is clear, the diopter is the mechanical iris.

I don't know how many have used a DSLR before, but the viewfinder has a diopter. If you wear glasses you can't easily press your face up against the camera. So the diopter allows you to correct your blurry vision without glasses. Whenever I have used it I have never attained super vision. It just does the same thing as prescription glasses.

And the benefit of being an iris, you can control the amount of light as well. So if you are light sensitive or the lights are way too bright, you can aim comfortably without squinting.

She reiterated that equipment is all about preference and comfort.

I can't argue anymore in the replies of this post. I have explained this 20 different ways. I have now shown actual words from a competitive shooter.

If you are allowed to correct your blurry vision, it seems only logical others be allowed to correct their light sensitive vision. This is a shooting competition, not a "I can endure bright TV lights" competition.

I think the novelty of the iris and its steam punk aesthetic is the only reason people are even talking about this. If it were a slightly tinted prescription lens I doubt it would have even been a conversation to begin with.

Two final things...

Yusuf Dikec *was* wearing hearing protection, it just wasn't very visible in the photos. It is not a rule to wear hearing protection but competitors are urged to do so in the pistol events. You can read more on that here.

Also, Yusuf was not in a singles event. He actually had a teammate, Sevval Ilayda Tarhan, who helped him win that silver medal. It kinda sucks that she got overshadowed as well.

I think that about wraps it up.

Take care, everyone.

This is frustrating.

I love the comparison, but I hate how they are comparing.

They are acting like she is using optics to give herself an advantage. But the device she is wearing is just for comfort and essentially does the same thing as closing one eye and squinting the other.

The little thing over the left eye is basically like an eye patch.

And the thing over her right eye is a mechanical iris, like in a camera lens, but it is NOT a lens.

Different lighting environments are going to be brighter or darker and you may have to squint more or less to let in the same amount of light into your eye. Squinting allows the shooter to get the sharpest possible vision in order to shoot a bullseye the size of a 12-point Times New Roman period.

But if you have to squint for hours for practice and in competition, this can strain your face muscles and become uncomfortable. So this iris basically squints for you.

It's more like wearing comfortable shoes so your feet do not hurt than a lens magnifying the target and giving an advantage.

Both athletes have access to these items. One felt more comfortable without them. The other didn't feel like getting a muscle cramp from squinting all day.

Either would have shot the same if they had or had not used these devices.

Just a funny difference in gear preference.

I should also add, the Turkish dad is the only one using lenses.

How to Choose the Perfect Reading Glasses for Long Hours of Work?

Introduction

For those who spend long hours reading, working on a computer, or engaging in detailed tasks, choosing the right reading glasses is essential. Poorly fitted or low-quality glasses can cause eye strain, headaches, and discomfort. This guide will help you understand what to look for when selecting Reading Glasses for men to ensure comfort, clarity, and long-term eye health.

Why Proper Reading Glasses Matter?

Many people underestimate the importance of choosing the right reading glasses. Wearing the wrong pair can lead to: ✔ Eye fatigue and strain – Blurry vision and discomfort from incorrect magnification. ✔ Headaches and dizziness – Caused by poor-quality lenses or improper fit. ✔ Neck and posture issues – Constantly adjusting your head position to see better.

Key Features to Look for in Reading Glasses

To ensure all-day comfort and efficiency, high-quality Reading Glasses for men should include:

Correct Magnification Strength

Choose the right diopter (lens power) based on your vision needs.

If unsure, get a professional eye test for accurate prescription strength.

Blue Light Filtering Lenses

Essential for those who spend long hours on screens.

Reduces digital eye strain and improves sleep quality.

Lightweight and Comfortable Frames

Avoid heavy glasses that put pressure on your nose and ears.

Opt for lightweight materials like titanium or acetate.

Anti-Glare and Scratch-Resistant Coating

Enhances clarity and prolongs the lifespan of your glasses.

Reduces reflections for a clearer and more comfortable reading experience.

Choosing the Right Frame Shape for Comfort and Style

Reading glasses should be both functional and stylish. Here’s how to choose the best frame shape for your face type:

Oval Faces – Almost any frame shape works well.

Round Faces – Rectangular or square frames add structure.

Square Faces – Round or oval frames soften strong angles.

Heart-Shaped Faces – Bottom-heavy frames balance facial proportions.

Are Expensive Reading Glasses Always Better?

Not necessarily. While premium brands offer better materials and durability, many budget-friendly options provide excellent quality. Always look for UV protection, high-quality lenses, and a good frame fit rather than just the brand name.

Why Invest in High-Quality Reading Glasses for Men?

Unlike generic drugstore reading glasses, high-quality Reading Glasses for men offer: ✔ Sharper vision without distortions. ✔ Better eye protection from digital strain and harmful light. ✔ A stylish, professional look suitable for work and casual wear.

Final Thoughts: Are These Glasses Ideal for Long Hours?

Absolutely! Whether you're reading books, working on a computer, or reviewing documents, investing in high-quality reading glasses ensures clarity, comfort, and long-term eye health.

Would you consider upgrading to premium reading glasses?

Dive Mask with Reading Lenses: Enhancing Underwater Vision for Every Diver

For divers who need help with close-up vision, a dive mask with reading lenses is an essential piece of gear. Whether you struggle to see your dive computer, pressure gauge, or underwater camera screen, reading lenses (also called bifocal or gauge reader lenses) provide the clarity needed for a safe and enjoyable dive.

In this guide, we’ll explore the benefits of a dive mask with reading lenses, how they work, and how to choose the best one for your diving adventures.

1. What Is a Dive Mask with Reading Lenses?

A dive mask with reading lenses is a specially designed mask that features built-in magnification in the lower portion of the lenses. This allows divers to clearly read instruments and small details while maintaining a normal field of view for distance vision.

These masks are ideal for:

Scuba divers who have difficulty reading dive gauges or computers.

Underwater photographers who need to check camera settings.

Older divers experiencing presbyopia (age-related difficulty seeing up close).

Snorkelers who want clearer vision for close-up marine life observation.

2. Benefits of a Dive Mask with Reading Lenses

✅ Clear Vision for Instruments: With built-in reading lenses, you can easily check your air pressure gauge, compass, or dive computer without squinting or straining.

✅ No Need for Contacts or Bifocal Glasses: Unlike regular prescription dive masks, reading lenses eliminate the need for separate corrective eyewear, making diving more convenient and comfortable.

✅ Improved Safety: Accurate reading of your dive instruments is crucial for safe diving. With reading lenses, you reduce the risk of misreading depth, air supply, or navigation details.

✅ Enhanced Underwater Experience: Enjoy the small details of marine life, such as tiny fish, coral textures, and underwater artifacts, without struggling to focus.

3. How Do Dive Masks with Reading Lenses Work?

These masks function similarly to bifocal glasses. They have:

A clear primary lens for normal distance vision.

Magnified segments (diopters) at the bottom of the lens for near vision.

Common magnification options range from +1.0 to +3.0 diopters, allowing divers to choose the strength that best suits their needs.

4. Types of Dive Masks with Reading Lenses

🔹 Pre-Made Gauge Reader Masks: These masks come with pre-installed magnifying lenses, usually available in different diopter strengths. They are a convenient and affordable option for divers who only need mild reading correction.

🔹 Custom Prescription Dive Masks: For those with more specific vision needs, custom masks are available. These are tailored to your exact prescription, offering the best clarity both near and far.

🔹 Stick-On Magnifying Lenses: If you already own a dive mask, you can add removable stick-on lenses. These are an inexpensive way to convert a regular mask into a reading lens mask.

5. How to Choose the Right Dive Mask with Reading Lenses

When selecting the perfect mask, consider the following factors:

🔹 Diopter Strength: Choose the right magnification based on your vision needs. If unsure, consult an optometrist or test different strengths before purchasing.

🔹 Fit and Comfort: A good mask should create a watertight seal on your face. Look for soft silicone skirts that provide comfort and prevent leaks.

🔹 Lens Type and Visibility: Opt for anti-fog, scratch-resistant coatings to maintain clear vision throughout your dive. Some masks also offer wide-angle lenses for better peripheral vision.

🔹 Frame and Strap Design: A lightweight yet durable frame with an adjustable strap ensures a secure fit, preventing discomfort during long dives.

6. How to Care for Your Dive Mask with Reading Lenses

To extend the life of your mask and maintain optimal clarity, follow these care tips:

✅ Rinse after every dive – Wash with fresh water to remove salt, sand, and debris. ✅ Use anti-fog treatment – Prevent fogging by applying anti-fog solutions or using a mild baby shampoo rinse. ✅ Store in a protective case – Keep your mask in a case to prevent scratches and damage. ✅ Avoid touching the lenses – Oils from your fingers can reduce clarity and attract dust.

7. Conclusion

A dive mask with reading lenses is a game-changer for divers who struggle with near vision. By providing clear, magnified reading zones, these masks enhance underwater safety, comfort, and overall experience. Whether you’re exploring coral reefs, checking your dive computer, or capturing underwater photos, investing in a high-quality reading lens dive mask will make every dive more enjoyable and stress-free.

So, before your next underwater adventure, upgrade your gear and enjoy the clear vision you deserve!
