What are Progressive Lenses and How Do They Work?
Progressive Lenses and how they work
Progressive lenses, also known as multifocal lenses or varifocal lenses, are a type of prescription eyewear designed to correct vision at multiple distances. So, a person is able to see clearly near, intermediate and far distances without having to switch their eyeglasses, nor do they have to deal with the inconvenience of bifocal lenses. These lenses are especially useful to correct presbyopia, a common age-related condition that affects the ability to focus on close objects.
Gradual transition in the lens power - Progressive lenses are designed for a gradual transition in the lens power to support seamless vision correction at all distances. The upper part of the lens is optimized for distance vision, the middle part corrects the intermediate vision, and the lower part of the lens is for near vision correction.
Comfort and convenience - Because progressive lenses create a seamless transition between different focal lengths, the wearer experiences a more natural visual experience, as they get used to shifting their gaze correctly. These lenses are crafted using advanced optical technology that ensures minimum distortions, providing a comfortable and clear view.
Adjustment period - Adapting to progressive lenses may require a short adjustment period. As wearers learn to position their eyes precisely for different focal lengths, their visual comfort and clarity begins to improve. Regular use of these lenses leads to quick adaptation and any discomfort the wearer may feel at the initial stages begins to subside. It’s important to note that proper fitting and alignment are crucial as even minor misalignments can affect vision clarity and comfort.
Progressive lenses are one of the best corrective solutions for people with multiple vision prescriptions. Once the wearer adapts to the lens type, they get to enjoy improved convenience and aesthetic appeal too.

Everything I learn about American healthcare makes it worse lmao - insurance only covers the lenses? You're meant to what, hold them up to your eyes in your fuckin hands?
(Here, at least at the big chain opticians, we have to pay for our frames (though there may be exceptions if you're on certain benefits, can't remember); the lens is packaged in with that unless you want special treatment for them that makes them clearer/less flare-prone etc, or you have varifocals. There are usually like two frame options that are very cheap, £15 or so, and a couple more under £50, but if you're up for spending £70 you get 2 for 1. So I do that. Because I have a delicate baby head that can't deal with wearing the same pair of glasses for more than four hours or so. Also my mum always gets two and I've seen her be glad of it often enough to want to follow suit.)
this is about the glasses poll? I have really bad glasses insurance and my whole family has terrible eyes (I’m at -8 diopters, mom’s -4 and has the best eyes, dad’s at -10 or more, 2’s at -8 also, 3’s only ten and is at -4.5 or something), I know some people have better options because we’re on the absolute cheapest eye insurance from dad’s work. We get a $200 frame allowance or something every two years and a new pair of lenses every year, but have to pay for antiglare or blue screen light stuff or transition sunglasses lenses or whatever
it would be cheaper and more possible to get frames from Costco or something, but we all just have terrible eyes that nobody will make our lenses except the optometrist office so we need to get stuff through there.

Well ... eyes and feet test today
Wish me luck, although they shouldn't find anything untoward just yet. I look after my feet and eyes
I just hope that the weather remains murky and overcast as I don't have my sunglasses with me - not that they'll help any,I can't see out if them. Because they're just that. Sunglasses with no special varifocal lenses.

Had an eye test a couple of weeks ago and found I need some new glasses, even though I only had new ones last year. £261 for new varifocals with photochromatic lenses and a 'free' (not really 'cos I have to pay £60 extra for 'em) pair of prescription sunglasses which I really need 'cos the photochromatic lenses aren't cutting it when we do get sunshine at this time of year.
I went in to make a partial payment on them (since I can't afford to take £261 out of my £1060 Universal Credit payment along with my £700 rent and also bills and food) and got told if I didn't make the full payment by July 31 I'd have to pay the other £70 that they gave me off the price via an NHS voucher.
So there went my plan to pay it off over 3 months (I get my UC payments on the 5th of the month)! And now I guess I'll be eating a lot of toast and drinking a lot of water and not much else for the rest of June and all of July.
Anyway, the Tories are fucking cheapskates who are only in politics so they can line their own pockets. They're saying they'll cut off people's UC if they're out of work for more than a year, regardless of the reasons why AND they want to cut the disability benefit, too, if they get back in, so please, PLEASE, fucking vote them out on July 4th!

Factors to Consider While Installing Cameras in Daycare
Security concerns often put people in doubt. They feel threatened throughout if they find security standards compromised or doubtful. The increasing number of criminal cases has been raising this issue lately. People need more security at daycare and similar services. Along with physical security, people need digital safety as well. For example, they need childcare cameras installed everywhere on the premises. You can consider these factors when installing cameras when opening or operating a daycare.
Lenses:
Wide-angle lenses have been in demand. They offer more visible space. These camera lenses cover more area in a single frame. As a result, surveilling a larger area is easier with it.
It might be difficult to figure out where to install the camera. You might not be able to find the right location. In such cases, using a varifocal lens can help. It can help determine the right field of view.
Height:
Installing cameras may seem easy. But it can be tricky at times. Usually, relying on experts for camera installation is the best way to deal with such challenging moments. These experts know how to use the camera system for childcare correctly.
The tricky part is installing the camera at the right height. It would be best to keep the height 6.5 ft above the floor. It is enough to capture every detail within space. Cameras installed above 6.5 ft may be insignificant.
Lighting:
Installing cameras at the right place is crucial. It is necessary to keep the camera units aware of direct sunlight. Harsh light sources can also impact image quality. Therefore, choosing the appropriate position makes a substantial difference. Otherwise, images and footage captured by these cameras would make no sense.
Choose a space that is not highly affected by light. It would be better to find a corner that can cleanly record everything. Expert camera installers can easily determine the right position for these cameras. Hence, high safety standards can be established in the daycare for consistent digital security.
About ZOOMiN LIVE:
ZOOMiN LIVE can help you with childcare camera installations, allowing childcare and daycare services to share live-stream videos with families. The daycare cameras capture clear footage that anyone with access can check and see what their child is up to. The best part is that families can access these live streams through any device, from smartphones to personal computers.

Guy who works in an opticians here...
Of course I can't speak for every practice, and I work for an independent rather than a big chain, but buying glasses and contact lenses online is only going to lead to opticians closing, and then who will be able to conduct your eye tests? And repair your frames when you don't want to buy another pair? Also for complicated lenses like varifocals or bifocals, you need additional measurements as well as your PD, which often needs to be specifically measured in your chosen frame to get them accurate otherwise you're gonna have problems, and then where do you go to try and get them sorted? TO AN OPTICIANS! The number of people who come in who have problems with glasses and contact lenses they've bought online is insane, and then they end up spending MORE MONEY because we have to make them up new specs or get them different lenses in the end anyway.
Speaking of contact lenses, please PLEASE have yearly checkups so we can check your eyes are still healthy and okay with having lenses in. You should only go for contact lenses if you REALLY want to, it's a lot of daily work to use them healthily and safely, and you'll need a pair of glasses as well for when you're not wearing them, because you need to give your eyes a break from them and should NEVER wear them from the second you wake up to the second you get into bed. Also make sure you get a proper contact lens teach when you first try them, again so you know how to look after them and take care of your eye health, and also to pick up the best techniques for getting them in and out of your eyes. This also means if you can't get them out, an optician is on site to do so.
Please take from this, support your local independent opticians if you can. We train long and hard for a reason. And if you have to buy specs online, ONLY buy low prescription single vision, and ONLY buy the type of lenses you've been prescribed by an optometrist.
can we talk about how literally 64% of people wear glasses, and yet we NEVER see them in movies/tv unless it's on some nerdy or uncool character? why do we adhere to such a weird beauty standard that subconsciously makes us feel bad for,, not being able to see???
