Contact Lenses

For those of people who have vision problems, wearing prescription glasses is sometimes not a suitable option for aesthetic and functional reasons. Reading glasses can be uncomfortable, and keep track of them is a hassle. This is why many people opt for contact lenses as a treatment to improve sight. At first wearing contact lenses might be difficult, but once you use them a few times, they are easy, convenient, and you won’t even know they’re there.

Contact lenses are small flexible plastic disks that cover the entire surface of the cornea right over the lens. Many people use contact lenses for cosmetic purposes to change the colour of their eyes, and some others use them to give them sharper vision even when their vision is perfectly normal. However, most people who wear contact lenses use them to help with near and farsightedness.

As contact lenses stick to the eye, they provide a natural field of vision, rather than a pair of eyeglasses would be able to. This is why although eyeglasses help you see better, over time eyestrain becomes an evident side effect.

Contact lenses provide for better vision than eye glasses do, and they are more effective in maintaining your current vision. If someone has a refractive error, either where the light is not reflected on to retina correctly, light can be struck either above the centre or below, making your vision blurry or grainy. Contact lenses stick to the cornea using the tear fluid, and eyelid pressure. Blinking keeps contact lenses clean as it would your natural cornea and therefore you are able to keep them on for about 8 hours of the day without a problem.

There are various types of contact lenses, which help in both types vision problems, including presbyopia which is problem of both near and farsightedness.

A concentric bifocal lens is able to correct near and farsightedness with a single lens. The lenses are generally separated into two sections, where the centre is responsible for either one of the problems and the outer circle helps with the other.

A translating lens is similar to bifocal lenses, but the instead of circular sections, its instead separated into the top and bottom sections that help with both types of sight.

An aspheric lens places both the nearsightedness and farsightedness at the centre of the lens to allow for a more balanced vision.

In addition to lenses helping with your sight, lenses are prepared for different functional purposes. There are disposable contact lenses, daily use lenses, extended wear lenses, ultra-violet protection lenses, colour tinted lenses for cosmetic uses and even super lenses meant for use by athletes who require sharp vision to play in the field.
