KLIM OTG are clip on glasses that block out blue light. These glasses are anti-eye fatigue, anti-UV and anti-blue light, allowing for a high screen protection. Perfect for long gaming sessions on PC, Mobile and TV.

Take care of your eyes’ health. The human eye hasn’t evolved to stare at a screen many hours a day. This is why the blue light from screens leads to many health issues down the road. The main ones are the retina macular degeneration as well as cataract. Protect yourself today.

Improve your sleep. Screens prevent you from quickly falling into a restful sleep, notably by messing with your circadian cycle. This is caused by the blue light. By filtering it, you can very quickly fall asleep and enjoy a full night of proper rest. Invest in your sleep!


Anti-fatigue, anti-headache and become more productive. Do you ever, after spending a few hours in a front of the screen, get tired eyes — maybe they feel a bit dry — or a headache? The KLIM OTG will solve this: your eyes will be rested and you will be more attentive. If you play video games, this will allow you to play at peak performance.

Convenient and affordable prices. We have identified a problem in the market for anti-blue light glasses. The KLIM OTG clip-on has been designed to fit easily and perfectly to most existing eyeglass models. With the KLIM OTG clip-on we wanted to offer an excellent protection at a reasonable price.

High quality. Our glasses filter 86% of the blue light — way higher than the industry average. The lenses are German made. The frame is partly made of TR90, a very robust but light material. The glasses only weigh 15g, you won’t feel them on your nose.

Important. These lenses must be attached to your normal glasses. If you don’t use glasses, we recommend the KLIM Optics.
