Types of contact lenses

Bifocal Contact Lenses

Bifocal contact lenses have two prescriptions in the same lens allowing different
focus zones for near and far sighted correction. Bifocal contact lenses come in both

soft materials and GP materials. Some can be worn on a disposable basis.

That means you have the convenience of throwing the lenses out at specified intervals (even daily, in some cases) and replacing them with fresh, new lenses.

Bifocal contact lenses are designed to provide good vision to people who have presbyopia, a condition where the eye exhibits a progressively diminished ability to focus on near objects as a result of aging.–usually first noticed between the ages of 40 and 50. The optometrists at the Optical Studio will help you select the right bifocal contact lenses.


Toric Contact Lenses

Toric contact lenses are made from the same materials as regular (“spherical”) contact lenses, so they can be either soft or GP. The difference is in the design of the lens. Toric lenses have two powers, 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.


Colour Contact Lenses

Coloured contact lenses are available in 3 options: visibility tints, enhancement tints and opaque colour tints.

Coloured contact lenses are available in plano (for cosmetic purposes), as well as designs for people who need prescription contact lenses. Most coloured contact lenses are disposable.

 

Silicone Hydrogel Contacts

A new generation of “super-permeable” contact lenses can transmit unprecedented amounts of oxygen to your cornea and, in some cases, enable 30 consecutive days of wear without removal. Silicone hydrogel contact lenses represent a breakthrough over traditional hydrogel soft contact lenses, because silicone allows much more oxygen (essential for a healthy cornea) to pass through the lens.


Disposable Contact Lenses

Disposables have become the most popular type of contact lenses which are worn for a specific period of time, then thrown away and replaced with a fresh pair.

Types of disposable contact lenses:

  • Daily – Discard after a single day of wear.
  • Weekly – Discard every two weeks, or sooner
  • Monthly – Discard monthly or quarterly
  • Reusable – Discard every six months or longer

All of these lenses, except the daily disposable lenses, need to be removed and cleaned every night.

Extended wear contact lenses may be the right option for you if you would like to wake up each day with clear vision. Most extended wear lenses can be worn without removal for up to seven days.
