Official step-by-step handling protocols and safety rules from Keen Sight Optical Chamber.
Your lenses have been clinically matched to your eyes. Follow this quick visual guide to maintain all-day comfort and protect your vision.
Wash thoroughly with plain soap. Dry with a clean, lint-free towel before touching lenses.
Place on fingertip. Ensure it forms a smooth, round bowl and edges do not flare outward.
Hold upper and lower eyelids steady. Look straight ahead, place lens gently, and blink slowly.
Store in clean case filled with fresh solution. Never reuse or top off yesterday's liquid.
Discard storage fluid daily and refill case with fresh multipurpose solution.
Never expose lenses to tap water, filtered water, showers, or swimming pools.
Clean your lens case with solution, let it air-dry, and replace it every 3 months.
Always remove lenses before sleeping unless prescribed specialized Ortho-K lenses.
If your eyes feel irritated or stinging, remove lenses at once. Never force uncomfortable lenses.
Sudden blur or light fogging indicates deposit buildup or corneal swelling requiring clinical review.
A sandy feeling usually means a trapped dust particle or damaged lens edge. Inspect before re-inserting.
