Scleral contact lenses are hard and almost similar to rigid gas permeable (RGP) lenses. They are larger in diameter than other conventional lenses and cover even the white part of the eye. These lenses form a layer of fluid known as vault over the cornea to keep the eyes moisturized. Scleral contact lenses are used to correct the problems caused by irregular cornea and keratoconus.
Benefits of using scleral contact lenses are
as follows:
Stability
The large diameter of these lenses keeps
them stay in place and stable on the eyes. This helps in providing clear and
consistent vision to the wearer. The chances of them to dislodge or pop out are
almost nil, even while playing sports or engaging in any other activity.
Reduces dryness
Scleral lenses create a vault of fluid
between the cornea and the lens which keeps them stay centered all day long.
This fluid layer consistently moisturizes the surface of the cornea so that the
contact lenses can be worn throughout the day. These lenses work best even for
people having the problem of dry eyes.
User friendly
Many people especially with poor eye
sight or with manual dexterity problem, find difficulty in using regular
contact lenses due to their small size. Scleral
contact lenses on the other hand are larger in size which makes it easy to
insert and remove them. It is extremely easy to use and handle these lenses and
also the chances of any complications are very less.
Durable
Scleral contact lenses are made from
high quality and durable materials which make them last long. Though, the
initial fitting cost of the scleral lenses is more than the conventional
contact lenses but over the time, you will get maximum value for the money.
Wide visual coverage
Because of their extra-large size,
they provide more visual coverage and precise peripheral vision. Scleral lenses
also less sensitive to light and glare.
Used for cosmetic purposes
Nowadays, scleral contact lenses are
also used for cosmetic purposes and can be custom made. Even for cosmetic use,
one must ensure to get the prescription from an experienced eye doctor and get
them fitted correctly. If not done, this could lead to serious eye infection or
permanent vision loss.
