Contact Lens Solution: Step‑by‑Step Safety and Hygiene Guide

Proper lens care is essential to prevent microbial keratitis, a sight‑threatening infection. Follow this protocol every time you handle reusable soft or rigid gas‑permeable (RGP) lenses.

Daily Routine

1. Wash hands – soap and water, dry with lint‑free towel. Avoid moisturizers, oils, or fragrances.
2. Inspect solution – check expiration date; discard if cloudy, discolored, or >28 days after opening (per manufacturer).
3. Remove lens – place on palm, apply a few drops of fresh multipurpose solution.
4. Rub & rinse – gently rub each side for 10–20 seconds (even "no‑rub" solutions benefit from rubbing). Rinse thoroughly with fresh solution.
5. Disinfect – place in a clean case filled with fresh solution. Soak per label instructions (usually 4–6 hours minimum).
6. Morning insertion – rinse lens again with fresh solution before placing on the eye.

Case Hygiene

• Rinse case with solution (never tap water), air‑dry face down on clean tissue.
• Replace case every 1–3 months.
• Never "top off" old solution—always discard and refill with fresh solution.

Critical Don'ts

• ❌ Tap water, saliva, saline, or rewetting drops for storage/disinfection.
• ❌ Sleep in lenses unless FDA‑approved for extended wear and approved by your eye doctor.
• ❌ Swim or shower in lenses (risk of Acanthamoeba infection).
• ❌ Share lenses or solution.
• ❌ Use expired or contaminated solution.

Travel Tips

• TSA allows >3.4 oz medically necessary liquids (declare at checkpoint).
• Carry spare case, solution, and glasses.
• Daily disposables eliminate solution needs entirely.

When to Call Your Eye Doctor

• Redness, pain, photophobia, discharge, blurred vision, foreign‑body sensation.
• Remove lenses immediately and seek same‑day evaluation.

Annual corneal health exams are essential even if you feel fine.
