Contact lenses, also known as coloured lenses, are thin plastic lenses usually placed directly on your cornea (the topmost layer of the eye). Contact lenses are one of the most comfortable optical devices ever created, allowing you to wear eyeglasses or contact lenses whenever you need them. Contact lenses have been used for over 150 years and can greatly improve your vision. Many people wear contact lenses because of the benefits they provide but there are many other people who wear contact lenses because it is just fashionable.
If you wear contact lenses because it is just fashionable, then you should know that using contact lenses will not correct any refractive errors in your eyes; in fact, if you want to get rid of your glasses, you should look into glasses instead. However, if you wear contact lenses to correct your vision, then you should be aware that these lenses cannot replace your glasses and will not restore your vision to the way it was before you wore your contact lenses. Contact lenses are only optical prosthetic devices designed to be worn in order to correct your vision; they cannot replace your glasses or make your eyesight better than before.
There are two basic kinds of contact lenses: daily-wear lenses, which are usually worn every day, and daily-use prescribed lenses, which are prescribed to you once every two weeks. Some people wear their lenses for longer periods of time, such as every four months or so. However, daily-wear lenses should be cleaned according to the manufacturer’s instructions and should be discarded or recycled after every three months. Prescribed lenses, on the other hand, must be cleaned according to the company’s instructions and are required to be replaced on a daily basis.
Cleaning and maintaining your contact lenses is very important, because if they are not cleaned, they will accumulate a lot of bacteria and may even trap certain viruses in their porous structure. In fact, most eye doctors recommend daily cleaning or disinfection of lenses, because viruses can hide in a lens’s pores. It is also important to note that improper cleaning and care can irritate and even tear your lenses. If your prescribed lenses are prone to tearing, the doctor may advise you to buy new lenses more often. In this case, you will have to visit your optometrist every few weeks instead of once a month.
As far as presbyopia and astigmatism are concerned, most people with presbyopia think that contact lenses will help them correct nearsightedness or farsightedness. However, while some people find that wearing contact lenses helps them improve their vision, experts advise that you should not wear contact lenses if you have dry eyes. Dry eyes are a common problem among people who wear contact lenses, and a dry eye can cause your contact lenses to lose their effect, causing them to become brittle and fall out.
Once you are sure that your eyes are clean, it’s time to start cleaning your lenses. Remember that you will have to remove your contact lenses one at a time, and make sure to follow the instructions that come with your set. Be careful when cleaning, because some solutions, such as disinfectants, can damage the sensitive eye tissues. To avoid any unnecessary damage, consult your eye doctor before beginning cleaning.
