Contact lenses are an excellent option for people who want to get rid of their glasses. They are great if you engage in contact sports or are very active. Also, they have a much wider field of vision compared to eyeglasses.
However, there are various types of contact lenses. The lens the doctor will prescribe for you will depend on your eye condition. The doctor will most likely recommend regular contact lenses for hyperopia and myopia. But if you have astigmatism or another eye condition, the doctor may recommend specialty contact lenses.
Specialty contact lenses are specially made for patients with specific eye issues. These could be corneal or ocular conditions that regular contacts cannot treat.
Most regular contacts cover the cornea by sitting on the eye's surface. For this reason, they must be well fitted. When you have corneal conditions, it becomes difficult to fit the contacts for your eyes. Several other conditions require specialty contact lenses. They are:
Regular contacts are not able to treat these conditions. A few years ago, most people with these conditions could not qualify for contact lenses. When specialty contacts hit the market, more people who could not wear contacts were now able to get a prescription for their condition.
Optometrists often recommend these lenses for patients with dry eyes. The design of this lens allows a lot more oxygen to permeate through. This consistent flow of oxygen is healthy for the cornea, helping keep the eye moist.
This makes the rigid gas permeable contacts much more comfortable for people with dry eyes than a regular contact lens. Their rigidity helps the cornea maintain its shape. This is good for some conditions with abnormalities of the cornea.
This type of lens sits on the eye's sclera and vaults over the cornea. It can do this because it has a much larger diameter than regular contacts. Because of this design, there is a gap between the lens and the cornea, which is usually filled with a tear film. This makes it ideal for people who suffer from dry eyes. Optometrists prescribe scleral lenses for patients with surgical scarring or keratoconus.
This type of lens is a groundbreaking solution to correcting vision. Optometrists prescribe ortho-k lenses when they want to address myopia progression. These lenses are worn at night to reshape the cornea.
During the day, the patient will have near-perfect vision. Ortho-k lenses are very effective in slowing down myopia progression in children. It is a preventative measure for issues that occur with severe myopia.
These lenses are great for people who have astigmatism. They are designed to address the cornea's irregular shape that comes with astigmatism. They can accomplish this because they have different powers in different lens areas. They are primarily thick at the bottom and thin at the top.
