Maintaining eyes’ health properly is a major challenge these days along with changes in the kind of food consumed by most of us. People use special kinds of contact lenses for various reasons other than the regular contact lenses.
There is a list of reasons and conditions where specialty contact lenses are used by people.
Mostly they include Corneal Scarring, Presbyopia, Keratoconus, Astigmatism, Dry Eyes, Pellucid Marginal Degeneration, Post-LASIK or other refractive surgery and Giant Papillary Conjunctivitis (GPC).
Under these special health conditions, the patients need contact lenses, as it is difficult to wear the regular contact lenses.
Measures To Be Taken:
As per the advancing technology, there are different kinds of specialty contact lenses available to fit as per the eye condition of the person. These products not only serve the purpose but also gives great comfort during regular use.
As these are special eye conditions, it requires a specialized fitting also by an expert eye doctor.
Kinds Of Specialty Contact Lenses:
People with keratoconus condition have limited vision with regular glasses or lenses when compared to specialty contact lenses, which are designed especially for irregular corneas.
These contact lenses will develop the quality of vision optically by uniform and smooth cornea surface with the irregularly shaped cornea.
These Contact Lenses Are Divided Further into Different Types Namely:
- Gas Permeable Contact Lenses: These are for the ones who are having mild or moderate keratoconus, rigid gas permeable contact lenses are recommended by most of the lens specialists.
Also called as GP or RGP lenses, as they are made of a rigid oxygen-permeable material. Due to the permeable material, they do not conform to the shape of the cornea and keep their original shape. This makes the RGP eliminate irregularities in the cornea and give sharper vision than the glasses and regular contact lenses.
- Piggybacking Contact Lenses: Although GP lenses have a crystal clear and blur-less vision, their rigid nature is not comfortable for everyone. Particularly for those suffering from keratoconus, they cannot wear this lens for the whole day.
Piggybacking can solve the issue, which is a soft contact lens worn under a gas permeable lens which it stands as a cushion to cut any discomfort caused by the GP lens.
- Scleral Contact Lenses: At times, conventional GP lens fails to properly fit on to the center of the eye and may cause dislodging during eye blinks. This usually happens when the corneal surface of keratoconus bulges.
An ideal contact lens specialist will give the GP lenses with large-diameter known as Scleral Contact lenses. Their name is given due to the fact that the lenses rest upon the white sclera of the eye and settle over the irregularly shaped cornea.
These Scleral lenses offer better comfort and protection when compared to the smaller GP lenses, as much pressure is not exerted on the sensitive corneal tissue.
- Hybrid Contact Lenses: Alike the earlier mentioned contacts, the Hybrid Contacts are larger in diameter, along with a soft or silicone hydrogel made peripheral zone. The Hybrid lenses are similar to soft lenses.
Same as the other contact lenses, the Hybrid Contacts vault over the irregularly shaped cornea with a special design. Correcting the nearsightedness and astigmatism is also another importance with Hybrid lenses.
Before choosing the specialty contact lenses, it is always important to take a proper guidance from the ophthalmologist. The concerned eye specialist may check the health of your eye.
Depending upon the condition of it would suggest what kind of contact lenses are required. As mentioned before, it needs some special conditions of the eye diseases to consider employing specialty lenses.
Apart from the usage of contact lenses, one needs to keep in mind that vision can be improved by consuming better food.
