Distinct Vision / Glasses for color blindness

Distinct vision is a device developed for the color-blind to carry easily and help them recognize colors.

When you need to use it, you can unfold and roll it to wear like glasses.
Its lenses help color-vision enhancement: it has a filter that passes only wavelengths of 590-700n m, so that it may help people with red, green blue, yellow or other color blindness to significantly
improve their color discrimination abilities.
