Blue Light Clips

A blue light filtering lens that clicks onto the glasses you already wear.

It goes on for screen work and comes off when you're done, so you're not committing your only pair of glasses to a filter you want some of the time.

It's available with no power at all, or with reading power up to +2.00 in quarter steps if you want magnification at the same time.

The filtering itself is measurable: over 50% of light between 380 and 450 nanometers, the short-wavelength end of the visible spectrum.

How that feels is personal, which is exactly why we made it a clip instead of a coating. Wear it through a long stretch of screen work, take it off, and go with whichever you prefer.

Nothing about your regular glasses changes either way, so there's no commitment in finding out.

It's designed to stay visually neutral.

Chemistrie builds this filtering to preserve color and image quality, rather than throw the heavy amber cast you see on gaming glasses.

Any lens that filters part of the spectrum shifts color balance to some degree, so for color-critical work, photo editing, or print design, take it off for that part of the job.

Yes. There's no limit on wearing time.

Some people leave it on from morning email through evening TV. Others clip it on only after dinner. Both are fine.

Because it comes off in a second, you don't have to decide in advance.

Because a coating is permanent and a clip isn't.

Built-in filtering is on every hour you wear your glasses, including the ones where you'd rather have neutral color. A clip lets you choose. It also means you don't pay to redo your prescription lenses to try blue light filtering, and you don't lose it when your prescription changes.

If you already know you want it on all the time, built-in is simpler. If you're not sure, a clip is the reversible way to find out.

Over 50% of light in the 380 to 450 nanometer range.

That's the short-wavelength end of the visible spectrum, the band most often discussed in connection with screen glare and evening alertness.
