Prosthetic Contact Lenses for Eye Conditions
When you look at someone, the first few things you notice is the
other person's eyes. What you might not notice is that sometimes, those eyes are
covered by prosthetic contact lenses. Prosthesis is an artificial device that
replaces a body part lost by injury or missing from birth.
What are prosthetic contact lenses?
Prosthetic contact lenses are perfect for people who suffered
eye-injury due to an accident which might lead their eyes to become somehow
disfigured. It can also be worn by people who have eye defects since birth. It hides
the flaws and makes it invisible. Prosthetic contact lenses can also be worn for
people who are cross-eyed. It may also be completely colored to mask eyes that lost
its ability to see. Prosthetic contact lenses are soft and allow gas to pass through;
they are similar to regular soft or gas permeable lenses. No surgery is involved and
when prosthetic contact lens is put into place, the eye which has defect appears to
be normal again. Prosthetic contact lenses can disguise eye inconsistencies making a
person's eye/s look less awkward to look at which makes the affected individual less
conscious and much more confident to look other people straight in the eye. The
following are some eye deficiency problems that can benefit from using prosthetic
contact lenses:
- Anaridia - the failure of the eyes to develop normally. It can result as either
partial or complete absence of the iris tissue
- Albinism - known as the congenital discoloration in the eyes
- Diplopia - or double vision, a visual impairment wherein a person sees a single
object as two objects. Usually happens when one eye is covered.
- Nystagmus - is the involuntary shaking of the eye. Prosthetic contact lenses
comes in handy for masking eye movement and improving its appearance
- Photophobia - more known as light sensitivity. Prosthetic contact lenses reduces
the amount of light entering the eye.

much the same with regular contact lenses. Since prosthetic contact lenses are
hand-crafted,they are not disposable or for one time use only.
