Contact Lenses - A Buying Guide

Contact lenses, also known as regular lenses, are thin, extended lenses placed on the eye's surface. Contact lenses aren't always the most comfortable thing to wear, but there are several changes you can make to improve your comfort when wearing them. To find out which contact lens you should wear, you first need to understand a little bit about what they are and how they work.

The most common type of Silikon-Hydrogel Kontaktlinsen are called gas permeable lenses. These lenses are made from a gas, which is mixed with a small amount of lubricant. The lens is then held securely in place by a small ring on the top rim of each lens. The combination of these two helps provide stability and prevents water from leaking into the eye. These lenses are commonly used for short periods of time and can be removed when you need to get used to wearing them again.

Another type of contact lens is soft contact lenses. As its name suggests, soft contact lenses are thinner than most standard contact lenses, allowing more oxygen to enter the eye. Standard and daily disposable lenses are designed to keep debris out of your eye and prevent moisture from collecting in the cornea. Because soft contact lenses require a smaller insertion area, they are great for people who don't need to wear contact lenses very often. The trade off for this is that they take longer to adapt to. Also, because the thinner they are, you will probably need to change them more often.

If you wear lenses on a daily basis and find that you don't mind having them out in the open for the entire day, there are options for you. If you have vision problems, such as Astigmatism or nearsightedness, your optometrist may suggest the use of toric contact lenses. They are ideal for people with these types of vision problems because they offer reduced distortions and magnifications.

Some optometrists may also recommend extended wear lenses. Extended wear contacts are designed to be worn for longer periods of time than standard contacts. These are usually prescribed by ophthalmologists and optometrists, but you can order them online through a number of websites. Extended wear contacts are usually affordable, because they are designed to increase your comfort while still providing you with vision correction. Just like standard contacts, extended wear contacts are made out of an FDA-approved material.

If you find that daily contact lenses aren't comfortable or don't work well for your eyes, you may consider purchasing silicone hydrogel lenses. These lenses are made of a special silicone gel that allows for greater permeability than other contact lenses. This allows the eye to breathe and therefore prevent the buildup of debris in the eye, which results in irritation and discomfort. Silicone hydrogel lenses are available in soft, rigid gas permeable styles, depending on how much vision correction the patient requires.

If you would prefer to purchase your own contacts, there are contact lenses available to fit every kind of eye. Contact lenses with nocturnal effects, or those that correct both the near and far sightedness of the eye, are available to treat astigmatism, myopia (farsightedness), presbyopia (diminished focusing range) and farsightedness. A variety of brands are available in these categories. Colored vision corrective contact lenses, opaque lenses and toric contact lenses are available to treat either farsightedness or nearsightedness.

Purchasing contact lenses is an important decision. Make sure that you understand what you need and know exactly what brands are available before making your purchase. Make sure that your eye doctor is aware of any eye conditions that may have a negative impact on contact lenses. Be honest about your current prescription and be straightforward about which ones would be best suited to your eye care requirements. Follow the instructions that come with your contact lenses and you'll be sure to get great results. Your eye doctor will be able to advise you on the best contact lenses for your current situation and should help you choose the ones that are right for you.
