What Colorblind are you?
We've all come across heartwarming videos featuring people receiving color correction glasses as gifts, surrounded by loved ones, and witnessing colors around them for the first time. While these moments are touching, the question lingers: do color blind glasses truly deliver results? Many individuals passionately endorse these glasses, relishing the newfound ability to see rich, vibrant reds and greens. However, some remain skeptical. Let's delve deeper into this topic.
Color Blindness and Its Challenges: Color blindness, a condition complicating the differentiation of certain colors, primarily red and green, poses difficulties for affected individuals. Although complete color blindness is rare, around 5% to 8% of males and 0.5%-1% of females experience some form of color vision loss. This condition may be inherited or triggered by factors such as age, exposure to chemicals, certain diseases, or injuries.
Types of Color Blindness: Color blindness manifests in three main types: monochromatism, dichromatism, and anomalous trichromatism. Each type stems from distinct causes and presents unique challenges.
Challenges Faced by Color Blind Individuals: Navigating the world with color blindness can be unexpectedly challenging. Everyday tasks, like discerning ripe fruits and vegetables, become complicated. Certain professions, such as electricians, pilots, and medical professionals, may necessitate color vision, making color blindness a potential hurdle.
How Color Blind Glasses Work: Color blind glasses represent a relatively recent technological development. The first commercially available pair emerged in 2012, with subsequent models gaining popularity.
EnChroma Glasses: EnChroma glasses, pioneers in color-filtering technology, appear outwardly as regular sunglasses. However, their lenses filter specific wavelengths, particularly in the orange and yellow spectrum. Minerals embedded in the lenses selectively absorb targeted wavelengths, typically between colors like red and green. Rather than restoring color vision, these glasses reduce noise between colors, aiding mildly color blind individuals in distinguishing hues more sharply.
Other Brands and Technologies: Alternative approaches exist for managing color blindness. Some glasses opt for a high-saturation strategy, enhancing color intensity through polarized filters. While effective for some, particularly those with generalized color vision loss, outcomes vary.
Effectiveness and Limitations of Color Blind Glasses: While color blind glasses offer notable benefits, they come with limitations. Individuals with no color vision cannot expect improved results from filtered or separated wavelengths. Severe color vision loss may see improvement, albeit not always dramatically.
Positive Impact on Color Perception: Numerous positive testimonials emphasize the transformative impact of color blind glasses:
"Two of my sons are very color blind. My youngest son (8 at the time) was always deeply upset that he didn't know what seeing colors was really like...[I]t really has changed his life..."
"Bought these for my 21-year-old son, who has red/green color deficiency...He was able to see color as soon as he put them on!...It is truly a miracle."
Limitations and Varied Results: However, not all experiences are positive:
"My siblings and I purchased these glasses for our father, who has been color blind his entire life. He did not see any difference when first wearing them...It's likely he will not spend the recommended adjustment time..."
Factors to Consider: The efficacy of color vision correction depends on the severity and type of color vision loss. Candidates with mild or moderate red-green or blue-yellow color deficiency, focusing on distinguishing colors rather than total color perception, are more likely to benefit.
Conclusion: In conclusion, color blind glasses have undeniably brought positive changes to many lives. However, their effectiveness varies, and they may not be universally beneficial. Individuals with color vision concerns should consider an online vision exam to determine their suitability for affordable color-correcting lenses.
