Specialty contact lenses are used to correct irregular cornea conditions. They come in a larger design that vaults over the cornea. They cover the cornea completely with support from the sclera. This makes them comfortable because they do not disturb the sensitive cornea.
Patients require specialty eye contact lenses because of different conditions. For patients with astigmatism, specialty contact lenses are tolerable. For patients over 40 with reading problems, bifocal lenses with monovision eliminate the need for reading glasses. Even people with allergies photophobia and dry eyes can get specialty contact lenses that will not irritate their eyes. For people with keratoconus, they can start with soft contact lenses and advance with hybrid contact lenses. The good thing about specialty contact lenses is that they provide an optimal fit for different individuals.
Soft lenses are made with soft material that conforms to the shape of the eye. They are made using silicone and hydrogel material. They are easy to wear, adjust, and maintain. For people with mild vision problems and allergies, these are the best.
These are gas-permeable lenses made from a rigid material. They cover the cornea only and they provide a sharper image. They take longer to adapt to because they are not conforming. Gas-Permeable (GP) lenses are designed to last longer than soft lenses.
Scleral lenses are similar to RGPs, but they cover a larger part of the eye. RGP Lenses cover the cornea only. Scleral lenses cover the cornea and some part of the sclera. They are more comfortable than RGP lenses since they land on the white part of the eye. They are used to correct irregular corneas without disturbing them.
Hybrid lenses combine rigid and soft lens material. They come with a rigid center and a soft outline that lands on the sclera. They give the best service because they give a sharp image of the RGP and the comfort of the soft lenses.
Some people use contact lenses to change or enhance their eye color. This can be for a special occasion or use daily. Cosmetic eye contact lenses do not necessarily have to be prescribed. However, they should at least have UV protection and a sharp image. Most cosmetic lenses are made with disposable soft material.
The good thing about specialty eye contact lenses is that they are made to fit each patient by need. You can have different conditions for each eye and have lenses that correct the problems. Specialty lenses are also constantly evolving and growing with patients. Getting upgrades is easy in this technology era.
There are phenomenal applications on the horizon for specialty contact lenses. Enhancements such as diabetes detection, cancer detection, night vision, and improved vision correction are underway. Even for patients with allergies, glaucoma, infections, and inflammation, there is hope on the horizon. Lens manufacturers are working on high oxygen permeable materials and modern manufacturing techniques to make the most seamless contact lenses.
