Please come to try it and feel it.
EnChroma glasses enable some people with red-green color weakness to see an expanded range of colors more vibrantly, clearly and distinctly. The glasses are not a cure for color blindness, do not deliver 100% color vision, and do not work for all types of colorblindness.
(enchroma cannot help people pass Ishihara test)
There are 3 types of enchroma filters catering the need of different types of color problems.
Enchroma glasses can be helpful for some individuals with color vision deficiency, but their effectiveness depends on the type and severity of the color blindness. They do not “cure” color blindness or address the underlying issue permanently.
Enchroma specialty lenses enhance color contrast between red and green colors. It provides a colorful world to wearers.
How Enchroma glasses work
1. Filtering Technology
Enchroma glasses use special filters to reduce the overlap between red and green wavelengths, helping users distinguish colors that they might otherwise confuse.
2. Best for Mild to Moderate Deficiency
They are most effective for mild to moderate red-green color blindness (e.g., Deuteranomaly or Protanomaly) but are less effective or ineffective for individuals with severe deficiencies like Deuteranopia or Protanopia (complete absence of green or red cones).
Effectiveness
• When They Might Work:
• Improve color discrimination in specific lighting conditions, especially bright natural light.
• Enhance the perception of colors in daily life, such as distinguishing red flowers or green foliage.
• Limitations:
• Less effective in low-light conditions or artificial lighting.
• Ineffective for blue-yellow color blindness (Tritanopia) or total color blindness (Achromatopsia).
• Does not improve clinical test results, such as Ishihara plates.
Pros
1. Improved Color Experience: Some users report seeing more vibrant colors and improved contrast between red and green shades.
2. Non-invasive: No need for surgery or medication.
Cons
1. Results Vary: Not all individuals benefit from them, and some may find them underwhelming.
2. Limited Situations: Their effectiveness depends on good lighting and specific scenarios; they may not work well indoors or under poor lighting conditions.
