Specialty lenses are custom designed for patients with corneal conditions and vision problems for which conventional lenses are not ideal. There are two categories of contact lenses: soft lenses and rigid gas-permeable hard lenses. Specialty contact lenses remain an effective, invisible tool for individuals with vision issues.
 

The thin lenses correct problems such as presbyopia, astigmatism, myopia, keratoconus, dry eyes, and light sensitivity. An eye doctor will determine whether the lenses are well-suited for you. Get regular exams to ensure your prescription is up to date. Different lenses are made for rectifying different problems. They include:
 

Soft Contact Lenses

Soft contact lenses are designed for people with dry eyes. They have water that enables oxygen to get to the cornea through the lens. If your eyes do not get sufficient oxygen, they can get cloudy, swell, and lead to blurry vision.

These lenses lessen dry eyes and help keep the cornea healthy. If you are looking for short-term lenses, soft contact lenses are the best option. Most of them are disposable, thus preventing eye infections. Most of these lenses provide UV protection.

Daily Disposable

You only wear these lenses for one day and then throw them away. This means you do not have to clean them. Those who clean their contact lenses improperly end up having infections and dry eyes.

Silicon-based Material

These lenses let in enough oxygen to the cornea and prevent the building up of deposits. They are not meant for everyone, so if you are interested in them, talk to your eye doctor.

Colored Soft Contact Lenses for Light Sensitivity

These are lenses worn by people who are sensitive to light. They include:

·      Visibility tint: They have a little color but are not enough to change your eyes' color.

·      Enhancement tint: They take up the color of your eyes but are darker than a visibility tint.

·      Color tint: They are opaque, darker in color, and change the color of your eyes.

Rigid Gas Permeable Lenses

These lenses are silicone-based, letting oxygen pass through to the eye. They correct myopia, presbyopia, keratoconus, light sensitivity, and astigmatism.

·      Monovision and bifocal contacts: Bifocal contact correct presbyopia, a condition in which your eyes lose the capability to focus far and near. Bifocal lenses will help individuals with far and near vision issues. Monovision has the same prescription in each contact. One contact is for distance vision, and the other is for close vision.

·      Toric Lenses for astigmatism: Work well with eyeballs that are not entirely round. They have two powers in each lens. One lens would correct astigmatism, and the other would correct farsightedness or nearsightedness. The options are soft and rigid gas permeable.

·      Lenses that shape the cornea:  Cornea refractive lenses or ortho-k lenses reshape the cornea, leading to significant improvement in vision. The wearer puts on these lenses at night and gets to enjoy good vision throughout the following day.
