Multifocal Contact Lenses

Multifocal contact lenses are worn for both cosmetic and functional reasons. They offer clear vision at multiple distances, making them an excellent alternative to reading glasses or bifocal spectacles.

Note on Design: These lenses provide both near and distance vision in a single lens. While clear functional vision is achieved, a small degree of compromise in absolute clarity compared to spectacles is normal.

Replacement Schedules

Daily Disposables

Daily Disposable Multifocals

Worn once and discarded daily. They offer the highest hygiene levels and reduced infection risk, with no cleaning or storage required.

Monthly Lenses

Monthly / Weekly Multifocals

Worn daily and reused for a set period. While more cost-effective, strict adherence to a cleaning regimen is essential to prevent complications.

Lens Care & Cleaning

Good hygiene is essential for safe wear. Always wash hands thoroughly and avoid lint-transferring towels before handling lenses.

Cleaning Systems

Common Cleaning Systems

  • - Multipurpose Solutions: Clean, disinfect, rinse, and store soft lenses.
  • - Hydrogen Peroxide: Highly effective disinfection; requires full neutralisation before insertion.
  • - Daily Cleaners: Manual rubbing to remove protein and lipid deposits. Cases should be replaced monthly.

Safety Checklist

DO DON'T
  • - Rub lenses during cleaning steps.
  • - Replace lenses and cases as directed.
  • - Insert lenses before applying makeup.
  • - Attend annual eye examinations.
  • - Use saliva to wet or clean lenses.
  • - Reuse (top off) old solution.
  • - Apply eyeliner on the inner lash line.
  • - Ignore sudden redness or pain.

UV Protection & Health

Some multifocal lenses contain UV-blocking agents. While these help reduce the risk of cataracts and photokeratitis, they protect only the cornea. Sunglasses are still required to protect the entire eye and surrounding tissue.

Critical: Sleeping in lenses reduces oxygen to the cornea, risking ulcers, hypoxia, and irreversible blood vessel growth.
