Contact Lens

What is Contact Lens ?

Thinking about trying contact lenses? Contact lenses are more versatile than ever before. Start by understanding the pros and cons of common types of contact lenses — and the ground rules for preventing eye infection
When it comes to contact lenses, it’s very important to know exactly what’s inside of them, or better yet, what they’re made of. Materials used have varied throughout the years. Earlier times called for more rigid materials that didn’t allow much oxygen to get to your eye. But as technology has improved, so has the availability of products. Based on current information on polymer technology as well as information from the U.S. Food and Drug Administration (FDA), lens polymers were divided into the filcon (hydrophilic) and the focon (hydrophobic) series, depending on their water content, which we will go over in the Silicone and Hydrogel section of this article. Still, we will also discuss what materials are in Soft, RGP and Intraocular lenses.

What is Low vision aids ?

Best corrected visual acuity of 6/18 or less and / or field of vision of 10 degree or less

In simple words…
People who are unable to see objects (say a person’s face) beyond maximum of 3m i.e., 10 feet distance (with their spectacle correction) and / or people those who have side vision difficulty are said to have low vision.
When ordinary eye glasses, contact lenses or intraocular lens implants cannot provide sharp sight, an individual is said to have low vision. Although reduced central or reading vision is common, low vision may also result from decreased side (peripheral) vision, a reduction or loss of clarity of vision, or the eye’s inability to properly adjust to light or glare.

What is Artificial eye ?

An artificial eye is a replacement for a natural eye lost because of injury or disease. Although the replacement cannot provide sight, it fills the cavity of the eye socket and serves as a cosmetic enhancement. Before the availability of artificial eyes, a person who lost an eye usually wore a patch. An artificial eye can be attached to muscles in the socket to provide eye movement.
Something that is often not considered at the beginning of an eye loss, but which becomes an important factor after surgery, is how one is going to look and deal with an ocular prosthesis (artificial eye), and most importantly the Ocularist you select to fit your prosthesis. In most cases your ophthalmic surgeon will refer you to an Ocularist they have confidence in. Having your doctor’s guidance at this time is very important to your ultimate result. If your doctor is not acquainted with an Ocularist, we invite you to consult with our staff before you decide where to have your ocular prosthesis fit.
