Many people can wear soft, conventional contact lenses. However, certain conditions of the eye make this impossible. These conditions make your eyes what is called, “hard-to-fit” for contacts. Fortunately, there are contacts that are designed for “hard-to-fit” eyes.
What Are the Conditions That Make Eyes Hard To Fit?
There are a few conditions that would make it necessary for you to wear special contact lenses.
- Dry eye syndrome: Contacts can dry your eyes out during the day. This can make your dry eye symptoms worse.
- Keratoconus: A normal eyeball is round. If you have keratoconus, your eye won't be able to hold its round shape, and it will bulge to the shape of a cone. This would make it impossible for a traditional soft contact lens to fit over your eye; therefore, a special lens would be necessary.
- Astigmatism: If you have astigmatism, your eye is misshapen. A typical soft lens won't conform to the eye so you would need to wear hard to fit contacts.
- Presbyopia: After the age of 40, your close-up vision can begin to deteriorate. This could require you to need two different prescriptions.
- Post Lasik surgery: After Lasik surgery, your eyes can dry out quickly, requiring a special lens.
What Are the Most Common Hard-to-fit Contacts?
There are several hard-to-fit contacts available. The most commonly prescribed lenses include:
- Daily lenses: Daily lenses are thrown away at the end of the day, and a fresh pair is inserted in the morning. They have a high water content which makes them great for dry eye syndrome or post Lasik surgery patients.
- Toric lenses: Toric lenses are soft lenses that are designed to treat astigmatism.
- Gas-permeable Lenses: These lenses are rigid and can hold their shape. They are often prescribed for patients with keratoconus because they can hold the shape of the eye. They are also used to treat astigmatism for patients who cannot wear toric lenses.
- Scleral lenses: These lenses are prescribed for patients with dry eye, keratoconus, and post Lasik surgery. They differ from traditional lenses because they don't rest on the eyeball. Instead, they rest on the white of your eye, and they vault over the eyeball.
- Bifocal lenses: Bifocal lenses contain two prescriptions, one for close-up and one for distance. These are prescribed for patients with presbyopia.
