Scleral contact lenses
Scleral
contact lenses also known as sclera lenses; are large rigid gas permeable (RGP)
lenses. They are completely different from the conventional lenses as they not
only cover the cornea but also the sclera, the white part of the eye. Their
size usually ranges from 14 to 20 mm in diameter. These lenses sit on the
sclera and form a vault over the cornea. This vault of fluid keeps the moisture
intact even if you wear them for longer duration. They modify the shape of
cornea in order to provide clear vision. Scleral contact lenses are an
effective option for correcting refractive errors and all the vision related
problems to irregular corneas. Scleral contact lenses are more comfortable to wear in comparison with other smaller
rigid gas permeable lenses.
If someone
is new to using scleral contact lenses, it might take some time to put them in
the eyes and while removing them. The wearer will need some time to get used to
them.
Some of the benefits of scleral
contact lenses include:
· More comfortable in comparison to
other corneal lenses
· Offer a stable fit even while playing
sports
· These lenses offer excellent vision
· Great for people having dry eyes as
they form a chamber of moisture
· Easy to adapt than RGP contact lenses
once they are correctly fit
· These lenses can be easily inserted
and removed
Special-effect scleral contact
lenses
The term scleral contact lenses are also used to
describe special-effect lenses that completely change the appearance of the
eyes and give them a dramatic look. These special-effect lenses are also known
as theatrical contact lenses, costume contact lenses, Halloween contact lenses
or gothic lenses. These soft lenses resemble only little to scleral contact
lenses apart from their large diameter that covers the cornea. These costume
lenses are not designed for vision correction as they are mostly used for
cosmetic purposes only. The most commonly used scleral contact lenses are the
completely black and red sclera lenses as they help in creating great effects
with your Halloween costume.
