Sclera contact lenses designed to be used in different scenarios

In the late
1800s, Swiss physician A.E. Fick and Paris optician Edouard Kalt were credited
with fitting the first contact lenses and they were fitted for the patients for
vision problems such as myopia and hyperopia. However, the contact lenses at
that time are made with heavy glass and could be used for a few hours only. These
lenses made of glass were termed as scleral lenses.
Scleral
lenses are large in diameter and cover the complete sclera, the white outer
coating of the eye leaving only a little portion in the sides of the eyes
visible. These contact lenses could only be worn for a short period at a time.
Later in the
1930s, PPMA - polymethyl methacrylate was development and was used in
combination with plastics for the manufacturing of contact lenses. These were
in fact known as the hybrid scleral lenses and were made with the combination
of both glass and plastic. Around the 1950s, much smaller contact lenses in
comparison to scleral contact lenses were developed. They cover only the cornea
of the eyes and not the complete eyes.
Apart from
the vision corrective ones, sclera
contact lenses are also available with special effects. Earlier, black
sclera contact lenses were used by theatrical and movie industries only.
Therefore, we all had commonly seen their use in the theatrical plays, movies,
photo shoots, and various other such activities. The most commonly available special effect
scleral contact lenses include the black-outs and the white-outs. These contact
lenses help the wearers in creating a dramatic look since they cover the white
part of the eyes also. They give an illusion of the whole eye being completely
black or white. This is the reason that makes these contact lenses so popular
if someone wants to create a look of the Gothic character. This makes them
ideal for achieving dramatic look and with complete ease. These sclera contact
lenses can be commonly used in different scenarios such as creating a villain
look in the movie, matching your Gothic costume in Halloween or any other
costume party for creating a scary look etc.
Sclera
contacts should not be worn unceasingly for long periods of time since
prolonged use can cause strain and infection in the eyes. And they should be
clean and disinfected carefully before and after each use, according to your
doctor's instruction. While using Halloween contact lenses, if you notice
issues such as redness, swelling, or feel any sort of pain, immediately contact
your eye doctor.
