Why Wear Contact Lenses?

Contact lenses offer freedom from frames and several functional vision benefits, including better peripheral vision and the ability to wear non-prescription sports gear or sunglasses.

Did you know? Roughly two-thirds of contact lens wearers globally are female, and the average age of wearers is approximately 31 years.

Lens Designs Explained

Toric Lenses

Toric Lenses

Corrects astigmatism by refracting light differently along two meridians, helping those with corneas that have different horizontal and vertical curvatures.

Monovision

Monovision

Corrects one eye for distance and the other for near vision. It is a common approach for presbyopia (age-related near vision decline).

Critical: Never sleep in lenses unless they are specifically approved for overnight wear. Lack of oxygen can lead to corneal ulcers and irreversible blood vessel growth.

Hygiene and Care Systems

Good hygiene is essential to prevent infection. Always wash hands thoroughly and avoid drying them with lint-producing towels.

Care Systems

Care Options

  • Daily Disposables: No cleaning required; discard after one use.
  • Multipurpose Solutions: Rinse, disinfect, and store soft lenses in one step.
  • Hydrogen Peroxide: Provides deep disinfection but requires careful neutralisation to avoid eye pain.

Lens Safety Checklist

DO DON'T
  • - Rub lenses when cleaning, even with "no-rub" solutions.
  • - Replace your lens case monthly.
  • - Insert lenses before applying makeup.
  • - Have an annual eye exam.
  • - Use saliva to wet your lenses.
  • - "Top off" old solution; always use fresh fluid.
  • - Apply eyeliner between the lashes and the eye.
  • - Wear lenses past their replacement date.

UV Protection

Some lenses include UV-blocking agents which help protect against cataracts and growths like pterygia. However, they only protect the area covered by the lens—sunglasses are still required to protect the surrounding eye tissues.
