Colorblindness, or color vision deficit, affects approximately 8% of males and just under 1% of women. The most common form is red-green color blindness, followed by blue-yellow color blindness. Red-green colorblindness is irreversible but can be significantly aided by corrective lenses and eyewear.
Colorblindness usually doesn't mean a complete absence of color vision. The main types include:
Red-Green Color Blindness:
Blue-Yellow Color Blindness:
Colorblind glasses come with specially tinted lenses that enhance color differentiation. They don't cure colorblindness but improve visual deficits in some cases.
Colorblind glasses vary based on the type and severity of colorblindness:
Colorblindness typically stems from overlapping responses to light by cone cells in the retina, which are sensitive to red or green light. Colorblind glasses use optical materials to filter specific light wavelengths, enhancing the distinction between colors.
Prices range from $200 to $450, with prescription versions costing more. Be cautious of cheap, ineffective alternatives.
Developed by Dr. Thomas Azman, this system uses special filters and tests to create customized lenses for individual color vision needs.
Research is ongoing in gene therapy, with notable progress by University of Washington professors in treating colorblindness in monkeys.
These glasses enhance the contrast between red and green but don't cure colorblindness or change the fundamental vision mechanisms. Their effectiveness varies among individuals and doesn't provide a true natural color vision experience.
