Do Colorblind Glasses Work?

To understand colorblind glasses well, you need to know how color blindness happens first. The human eye contains three photopigments that are sensitive to color. These photopigments are located inside receptors in the retina called cones, which can tell your eyes how much blue, red or green is in an object. Then they give your brain information about what color objects are.

If there is not enough photopigment in your eyes, you maybe can’t see that color. Most cases of poor color vision involve red-green color deficiency. That is to say, you have the difficulty in recognizing the red and green colors.

So, how do colorblind glasses work? Colorblind glasses like Enchroma were originally manufactured as sunglasses with lens coated in a special material that exaggerated the wavelengths of light. So, it has the effect of making colors look saturated and rich.

Though colorblind glasses do not cure color blindness or produce 100% normal color vision, they allow colorblind people to perceive colors they have never seen before and experience closer-to-normal color vision while wearing special glasses for color blindness.


Can you wear blue light glasses while driving?

The damage of blue light has a cumulative effect. The longer the exposure time is, the more serious the damage of retinal cells will be, which will eventually lead to irreversible damage of the structure and function of the retina. Once the retina has permanent damage, degeneration will directly affect the metabolism and function of photoreceptor cells, resulting in vision loss. It depends on the glasses you're wearing. The function of anti-blue light glasses depends on the material of the glasses. Some blue light glasses have a special anti-reflective coating, which can reduce glare. These glasses are definitely helpful when driving at night.



Half frame glasses

The half-frame glasses are more appropriate. A round face is wide on the left and right. For the half-frame, because it doesn't have a line underneath it, it will make the face look rectangular. Wearing the full-frame will make the jaw look narrower, and the jaw of a round face is narrow, so wearing the full-frame will make the jaw look narrower. Wearing a half-frame lengthens the jaw and makes up for the lack of a round face. On the other hand, full-frame glasses are more suitable for long faces.
