Step-by-Step Cleaning Process

1. Wash Your Hands

Always start by washing your hands with unscented, antibacterial soap. Rinse thoroughly and dry with a lint-free towel to avoid transferring debris to your lenses.

2. Inspect the Lenses

Before cleaning, inspect your lenses for any damage, scratches, or irregularities. Do not wear a damaged lens; consult your eye care provider for replacements.

3. Apply the Cleaning Solution

Place the lens in the palm of your hand. Add a few drops of the gas permeable lens cleaning solution. Using your finger, gently rub the lens in a circular motion for about 20 seconds. This removes dirt, oils, and protein deposits.

4. Rinse Thoroughly

Rinse the lens with a saline solution or the recommended gas permeable rinsing solution to remove any residual cleaner.

5. Store the Lenses

Place the cleaned lenses in their case. Fill each compartment with fresh gas permeable conditioning solution to disinfect and hydrate the lenses overnight.

3. Rinse the lenses thoroughly before wearing.
