Choosing Contact Lenses

People wear contact lenses for a variety of reasons. For many, aesthetics are the primary motivation, but many choose them for functional advantages like better peripheral vision and freedom during outdoor activities.

Market Insight: Globally, the average age of contact lens wearers is 31 years, with approximately two-thirds being female.

Spherical Contact Lenses

The most common type, these correct myopia (short-sightedness) and hypermetropia (far-sightedness) by focusing light evenly across the eye.

Monovision

Monovision

Corrects the dominant eye for distance and the other for near tasks. Over time, the brain adapts to allow functional vision at multiple distances.

Cosmetic Lenses

Cosmetic Lenses

Designed to change eye appearance. Because they are medical devices, a "zero-power" prescription is required to ensure a safe, legal fit.

Critical: Sleeping in lenses not designed for overnight wear increases the risk of corneal ulcers and irreversible blood vessel growth.

Usage and Care Systems

Before handling lenses, always wash hands with soap and avoid towels that shed lint. Proper care depends on your specific lens material:

  • - Multipurpose Solutions: Clean, rinse, disinfect, and store soft lenses in one step.
  • - Hydrogen Peroxide: Highly effective disinfectants that must be fully neutralised before the lens touches the eye.
  • - Daily Cleaners: Used to manually remove surface deposits by rubbing the lens in the palm of your hand.

UV Protection

Some lenses contain UV-blocking agents to help reduce the risk of cataracts and photokeratitis. However, contact lenses protect only the cornea; sunglasses should still be worn outdoors to protect the entire eye and surrounding tissue.

Contact Lens Safety Tips

DO DON'T
  • - Rub lenses during cleaning
  • - Replace lenses as prescribed
  • - Insert lenses before makeup
  • - Attend annual eye exams
