Bifocal Contacts and Multifocal Contacts
Both of these types of contact lenses help to provide clear vision at varying distances. Those with presbyopia-age-related blurring of near vision, such as when reading or working at the computer-may do best with bifocal or multifocal contacts.

Bifocal contact lenses come in both soft materials and rigid gas permeable materials. Some can be worn on a disposable basis. One lens manufacturer offers soft multifocal contacts made of silicone hydrogel material, which allows for up to 30 days of continuous wear.

The design of bifocal contacts and multifocal contacts falls into two basic groups:
Alternating vision or translating lenses works as your gaze shifts upward or downward because your pupil alternates between the two powers.
Simultaneous vision lenses require your eye to be looking through both distance and near powers at the same time. Your eyes will learn to select which power to use. The are two types of simultaneous vision lenses: concentric ring and aspheric.

Colored Contacts
If you want to change the color of your eyes, colored contacts are available. There are also special effect contacts, such as cat eyes for Halloween costumes.

Custom Contacts
These could work for you if other options fail because you have an irregularly shaped eye or too much astigmatism.

Orthokeratology Lenses
These are contact lenses that change shape the eye while being worn overnight. The reshaping and resulting improved vision last about a day; then you re-insert the contacts again when going to bed for the night.

Toric Contact Lenses
For astigmatism, toric contact lenses have two powers in them, created with curvatures at different angles (one for astigmatism, the other for either myopia or hyperopia). There’s also a mechanism to keep the contact lens relatively stable on the eye when you blink or look around. To provide crisp vision, toric contact lenses cannot rotate on your eye.
