Contact Lenses, or just contact lenses, are tiny thin lenses placed on the surface of your eyes. Contact lenses are small ocular prosthetic devices worn by more than 150 million individuals around the world, and they are used to correct eyesight or for various aesthetic or corrective reasons. Lenses are made up of a lens and a case made from soft polycarbonate.
There are two types of contact lenses that you can use. One is rigid gas-permeable lenses (RGP), and the other is nearsightedness or farsightedness lenses. The advantage of using rigid gas-permeable lenses is that they are less likely to experience abrasion. They also last longer because they don’t allow any moisture, such as water, to get inside the case.
On the other hand, soft contact lenses can cause dryness. When your eyes are dried out this way, there is more chance that protein, bacteria, and viruses may get into your eye and cause problems. Dry eye syndrome is very uncomfortable, causes tearing, and causes the eye to be much smaller than it should be. If you wear lenses for comfort, you should wear lenses that have a higher amount of water in them.
Wearing contact lenses isn’t right for everyone. If you have allergies, have astigmatism, are getting eye cancer, or your vision is currently impaired in any way, then you should talk to your optometrist before you start wearing them. Talk to your optometrist about whether or not you would need a refractive examination to make sure your contact lenses will work for your needs.
Gas permeable lenses can cost a little more money than soft contacts but they provide you with some great benefits. They are more comfortable because you can open them up more so that air can flow through them. They can also provide better vision because they work by increasing the lubrication of the cornea. Because of this, a thin film of moisture on the cornea doesn’t form which allows you to see better at close distances.
Before you buy contact lenses, talk to your optometrist about the options that are available. Although many people prefer to wear lens wear that provides comfort first, your eye doctor is probably more likely to prescribe you the correct contact lens solution for your particular situation. Don’t wear contact lenses if you have certain vision impairments such as astigmatism. There are contact lenses that can correct your astigmatism, but they can also damage your eye if they are not worn correctly. Talk to your eye doctor to find out which contact lenses will be best for you and which ones you should avoid.
