What goes into a pair of lenses
After you pick a frame, you make three choices. Here is what each option does and who it is for.
Prices will be published at launch.
What you’ll use them for
Your prescription decides this step. If it has an ADD number, progressives are an option.
Material and thickness
Stronger prescriptions make thicker lenses. A higher index bends light more, so the same prescription fits in a thinner, lighter lens.
Coatings and tints
Optional layers that protect the lens, cut glare or turn your glasses into sunglasses. Add only the ones you want.
Which thickness do I need?
Enter the SPH and CYL of the eye with the stronger prescription. We compare SPH with SPH + CYL, take the larger number and match it to a material.

Good to know
Short answers about the choices on this page.
is it worth adding?
It cuts the reflections that bounce off the lens surfaces. You get less glare from headlights and screens, and people see your eyes instead of a shine in photos and video calls. It matters more with thinner, high-index lenses, which reflect more light than standard ones.
does it help with screens?
It reduces part of the blue light from screens and daylight, and some people like the slightly warmer view. Studies so far have not shown that it prevents eye strain or eye disease. For tired eyes at the computer, regular breaks and an up-to-date prescription are the usual advice.
how long does it take to get used to them?
Most people adapt in a few days to two weeks. Wear them all day from the start, turn your head toward what you want to see instead of only moving your eyes, and look through the lower part of the lens to read. If something still feels off after two weeks, contact us so we can check the fit.
do they darken in the car?
Usually only a little, or not at all. Most light-responsive lenses react to UV light, and windshields block most of it. Some versions are made to darken partly behind the windshield. If you drive a lot in bright sun, a separate pair of sunglasses is often the better choice.
what is the difference?
Both make bright light easier on the eyes. Polarized lenses also block the glare that reflects off water, snow and wet roads, which a tint alone does not, but they can make some phone and car screens look dark at certain angles. A tint comes in solid or gradient colors. How dark a lens looks says nothing about its UV protection, so check for UV protection either way.
