Special filters in glasses can help color-blind people see colors better.

At least eight in 100 men (8%) and one in 200 women (0.5%) are affectedvision deficit in red-green

The number of people with this visual impairment is about 350 million worldwide.While people with normal color vision seeWith more than a million shades and shades, people with color deficits (or color blindness) seePatients with this diagnosis perceive colors as more muted and blurred, and some are more difficult to distinguish.

Scientists evaluated the influence of spectralnotch filters to enhance the chromatic responses of observers with a red-green color vision deficiency for two weeks of use. Filters (EnChroma glasses) are designed to increase the distance between color channels to help people with color blindness see colors more clearly, clearly and distinctly.

Study participants wore special glasses cfilters or placebo glasses. For two weeks, they kept a diary and were retested, but without glasses. Researchers have found that wearing special glasses enhances the reaction to chromatic contrast reactions in individuals with red-green color blindness. It is unclear how long the improvement lasts without the use of filters, but the facts show that the effect persists for some time.

When I wear my glasses outside, all the colors are very bright and saturated, and I can look at the trees and clearly tell that each tree has a slightly different shade of green compared to the rest.I had no idea how colorful the world was, and I feel like these glasses canHelp colorblind people better navigate color and appreciate the world.
