Contact Lenses are the most common prescribed reading glasses
They are typically used to treat different vision correction issues, such as: astigmatism, nearsightedness, farsightedness or presbyopia. Nearsightedness, also known as hyperopia, is a common vision disorder for which contact lenses have been prescribed by ophthalmologists and optometrists since the early 1900’s. Farsightedness or high-of-the-eye (FOA), is a rare but serious condition that often results from eye damage caused by past eye injury or corneal scarring.
The second category is the soft contact lenses, or HCP. This last type is the more popular variety, and accounts for the majority of contact lenses being sold today. The main difference between the two is the strength of the lens and how long it stays on the eye.
it is important to rinse your hands with sterile water prior to applying the solution
Rigid gas permeable contact lenses require a special solution every time you wear them. This solution, usually a special solution designed for the contact lens, must be applied and discarded prior to the next use. Because RGP contacts are so popular, optometrists often sell them at a discount. But over time, with continuous use, the solution tends to leak out, which results in eye irritation. This is why it is important to rinse your hands with sterile water prior to applying the solution to your eyes.
Soft contact lenses require a different solution to maintain the contacts on your eyes while you sleep. Since soft contact lenses do not have a gas-permeable gas exchange system, they do not require a disposable solution. What this means is that you can wear soft contacts throughout the night, without worrying about a clogging in your eye at some point during the night. If you do experience a minor eye irritation while wearing the soft contact lenses, it is often caused by the contact lens being air dried instead of moistened like the rigid gas permeable variety.
purchase the smallest size first
There are a few different sizes of contact lenses that one person can wear at one time. Your eye doctor should make sure that your eye prescription matches the appropriate size contact lenses before you buy. And just as you might need to see an eye doctor every six months to get a refractive surgery, you will need to have your eyes tested every one month to make sure that no problems with your eyes have come up since your last eye exam. Your eye doctor might also recommend a follow-up exam every one to three months to make sure there have been no changes in your eyes since your last exam.
When purchasing hard contact lenses or soft lenses for the first time, you may be tempted to purchase the smallest size available. This is not always a good idea, as the contact lenses will become less effective over time, especially if you wear them constantly. You should generally try to purchase a few sizes larger than your natural eye size, especially if you have a vision deficiency and frequently wear contacts. A few extra sizes of hard lenses may also be helpful if you frequently wear reading glasses or bifocals. You should talk to an eye doctor if you have any concerns or questions about your new contact lenses, especially if you plan on wearing them continuously for an extended period of time.
