Contact LensesSome people with aniridia opt for contact lenses with artificial iris with a fixed 5mm pupil. the Iris is either a dark tint which blocks out the light without changing the eye colour, or a paint iris which blocks out the light and appears as though the person has an iris. BenefitsUnobstructed field of view Correction refractive errors, such as farsightedness and nearsightedness Eliminate light entering the eye from the edge or above glasses They do not fog-up or get splattered, They are less noticeable than any eyeglass Easier to look into visual aids like monoculars There is also some evidence that contact lenses can help people with Nystagmus. DisadvantagesIncrease the risk of infections and corneal damage. limbal stem cell production is often weak in aniridic eyes, the cornea may take longer to heal from an infection or scratch to cornea, if at all Vision in low lit areas or situations such as at night time may hindered. Because the reduced pupil size cannot adapt to darkened conditions. Contacts take a lot more care and effort than glasses. More fixings and check-ups. They take longer to adjust to. Contact lenses cannot correct astigmatism as well as eyeglasses especially if the astigmatism is severe. Painted irises make look odd and as though the individual is staring. |
