Contact lens, or simply contact lenses, are very thin, even thin lenses placed directly upon the cornea (the transparent covering of the eye). Contacts are used by more than 150 million individuals worldwide, and they are often worn as a replacement for eyeglasses or to correct eye alignment or for aesthetic or medical reasons. For some, wearing contact lenses is not just a fashion accessory. Because they are made from a rigid gas-permeable material, contacts are able to be worn while sleeping and are even available for children. There are some important factors to consider in order to purchase a pair of contact lenses that will satisfy your particular needs. Here are some tips to help you choose and use the best contact lens.
One of the first things you should consider is whether you need corrective eyeglasses or just regular glasses. If you need glasses, then soft contact lenses will provide you with a better vision field than rigid gas-permeable ones. Additionally, you may have a corneal disorder that makes glasses ineffective or even dangerous. If this is the case, then soft contact lenses will be the most appropriate choice for you. If your eyes are healthy, then wearing glasses may be inappropriate.
In addition to the overall health of your eyes, the shape and size of your eye can affect the contact lens materials you choose. There are contact lens designs available in both spherical and extended-length styles, and your optometrist can give you the most suitable option based on your eye characteristics. If your eyes are close together, then you should get a design with one ball-shaped inner pupil and two curved outer pupils. If your eye doctor suggests that you get spherical lenses, then these should be curved to provide a more appealing look.
People with astigmatism should also be careful about their choice of lenses. Because these people’s eyes tend to compensate for their lack of sharp vision by bringing the sides of their eyes closer together, these people may get distorted results when wearing contact lenses. In some cases, these lenses may also cause eye irritation, even when worn properly. Your optometrist can give you the proper care for these individuals so as to ensure that they get the best results from using these products.
For those people whose eyes are close together but have a slight separation, GP lenses may be the best option for them. These lenses are available with one flat outer, two curved outer, or three different geometric designs. Generally, the contacts for close-compared eyes are softer than those for distant vision because the former needs to be thicker. Moreover, since distant lenses are not as thin, they are also lighter.
A person who wears vision corrector contact lenses for the first time may feel uncomfortable at first. However, as they get used to wearing these lenses, they will become accustomed to them and find comfort in using them. However, if you wear rigid gas permeable contact lenses, you must ensure that the lenses are fitting comfortably on your cornea. If you do not feel comfortable with the fit of the lens, you should contact your optometrist for the necessary corrective measures.
