Why Contact Lens Safety Matters

Poor lens hygiene can cause:

  • Eye infections (like keratitis or conjunctivitis).
  • Corneal ulcers (painful sores that threaten your vision).
  • Dryness, redness, and discomfort.

By following these simple contact lens safety tips, you can enjoy the benefits of contacts without risking your eye health.

Wash Your Hands Before Handling Lenses

Why it matters: Germs on your hands can transfer to your lenses and eyes, causing infections.
How to do it: Always wash your hands with soap and water, then dry them with a lint-free towel before touching your lenses.

Use Fresh Solution Every Time

Why it matters: Reusing or “topping off” old solution can lead to bacterial buildup and infections.
How to do it: Empty your lens case after each use and fill it with fresh disinfecting solution.

Replace Your Lens Case Every 3 Months

Why it matters: Old cases harbor bacteria and fungi, increasing infection risks.
How to do it: Mark your calendar to replace your lens case every 3 months—or sooner if it’s damaged.

Never Sleep in Your Lenses (Unless Approved)

Why it matters: Sleeping in lenses (unless they’re designed for extended wear) cuts off oxygen to your eyes, raising the risk of infections.
How to do it: Remove lenses before bedtime, even for short naps.

Avoid Water Exposure

Why it matters: Water (including tap, pool, and shower water) can introduce dangerous microbes like Acanthamoeba, which cause severe infections.
How to do it: Remove lenses before swimming, showering, or washing your face.

Stick to Your Replacement Schedule

Why it matters: Overwearing lenses leads to protein buildup, discomfort, and higher infection risks.
How to do it: Replace your lenses as prescribed—daily, bi-weekly, or monthly.

Clean Your Lenses Properly

Why it matters: Proper cleaning removes debris and bacteria that can irritate your eyes.
How to do it: Rub and rinse lenses with the recommended solution, even if they’re labeled “no-rub.”

Bonus Tip: Never Share or Reuse Lenses

Sharing lenses spreads germs, and reusing disposable lenses can cause irritation and infections.
