A bigger concern is that, if it blocks all LED wavelengths, it may also block brake lights of some vehicles.

It does not block wavelengths. It blocks light polarized in certain directions which may be of any wavelength.

Brake lights will most certainly not be polarized and so they will be dimmed by the same amount as most other objects emitting/reflecting non-polarized light.

Take in mind any glasses that reduce amount of light can be dangerous if used in poor lighting conditions (and yes, this includes those that purport to improve contrast).

hey lmilcin! I'm with the team behind the glasses. It sounds like you might know a thing or too about optics. We're looking for engineers and researchers that can help us solve the hard problem of blocking OLEDs for our next product. A lot of people think it’s impossible but we’re willing to give it our best shot!

Any chance you’re someone that can help?

Hi! I may have a tip for you. OLEDs emit at very specific wavelengths due to materials being used and there are very few materials that make for majority of displays. If you can create lenses that would selectively block very specific wavelengths (probably using same chemicals) then OLED displays would be dark or greatly attenuated and everything else that emits diffuse light would be only slightly attenuated (only small part of the continuous spectrum would be blocked at the specific wavelength).

Thanks for the tip! This is super interesting. We're experimenting with notch filters to block RGB. Is that what you're talking about here?
