Today’s lesson: Cleaning Non-Contact Exam Lenses. Read on for some do’s and don’ts of how to keep your Volk BIO and slit lamp lenses clean and clear for the best possible imaging. Regular care to remove smudges, oils, make-up, lint, and water spots will keep your non-contact lenses in great shape for years to come.
- rinse lens under warm running tap water.
- use a very soft, non-abrasive sponge, with a mild detergent, such as Dawn soap, to gently clean the lens surface.
- clean lens one side at a time in a clockwise direction. Cleaning in a counter-clockwise direction may loosen the glass element from the ring over time.
- dry the lens with a low-lint cotton, or cotton-synthetic towel. Old school baby diapers are a great choice. Microfiber cloths can be used to dry a wet lens, as long as the microfiber cloth and the lens are clean.
- scrub hard or rub the lens surface with force. This could cause damage to the anti-reflective coating over time.
- use microfiber cloths on a dirty dry lens. They can be used only if clean, to dry a clean, wet lens.
- dry lenses with paper products such as napkins, paper towel, or Kim Wipes as these may scratch the lens surface over time.
- air dry your lens; water droplets left to dry on the surface of the lens may deposit hard water minerals which will cause damage to the coating.
For quick, convenient cleaning, Volk also offers the Lens Pen and Precision Optical Lens Cleaner (POLC) wipes. The Lens Pen has a lint brush on one end and a carbon-fiber tip to gently remove smudges on the other end. Always be gentle with the Lens pen! POLC wipes are pre-moistened with an ethyl alcohol cleaning solution that dries instantly.
