How to clean blue light glasses
Why blue light glasses smudge so much
Blue light glasses smudge more than normal glasses because they are handled constantly during screen use. Face oils, fingerprints, and skincare transfer onto the lens every time you push them up or take them off at your desk.
The blue-light filter is a surface coating, so it must be cleaned as gently as an anti-reflective coating. Many blue light lenses combine a blue-light filter with an anti-reflective coating, which makes harsh cleaners even more damaging.
How to clean blue light glasses safely
- Rinse both lenses under lukewarm water to lift off dust before wiping.
- Apply an alcohol-free, ammonia-free lens spray to each side.
- Wipe gently with a clean microfibre cloth until the lens is clear.
- For heavy screen users, clean once a day so oils do not build into a stubborn film.
What to avoid
- Do not use alcohol wipes on blue light glasses, as alcohol strips the filter coating.
- Do not use household glass cleaner, which contains ammonia.
- Do not wipe them on your shirt at your desk, which grinds in grit and oil.
Frequently asked questions
What can I use to clean blue light glasses?
Use an alcohol-free, ammonia-free lens spray with a microfibre cloth, and rinse the lenses under lukewarm water first. Avoid alcohol wipes and household glass cleaners, which strip the blue-light filter coating over time.
Can I use alcohol wipes on blue light glasses?
No. Alcohol wipes can strip the blue-light filter and any anti-reflective coating on the lens, leaving it cloudy or discoloured. Use an alcohol-free lens spray designed for coated lenses instead.
How often should I clean blue light glasses?
Clean blue light glasses once a day if you wear them at a screen, because face oils and fingerprints build up quickly. Rinse, spray with an alcohol-free cleaner, and wipe with a microfibre cloth.
Why does my blue light coating look patchy or discoloured?
Patchy or discoloured blue light lenses usually mean the coating has been damaged by alcohol, ammonia or heat. A damaged coating cannot be restored, so clean with an alcohol-free spray and a microfibre cloth to prevent it.
