Yellow lens tints are becoming popular in the eyewear industry. They are commonly used for environments that appear brighter and low-light conditions. These lens tints block blue light and enhance contrast and depth perception, making them great for overcast, hazy and foggy conditions. It is also evident that blue light improves sharpness and depth perception and reduces fatigue.
Research shows that the removal of blue light in yellow lens tints have a wide range of health benefits, including:
Improves Sleep problems – Studies show that excessive light, especially blue light given off by computer screens, televisions and ambient light in most homes, suppresses melatonin. Melatonin, our natural sleep hormone, helps us get to sleep. For those struggling falling asleep, wearing lenses that block blue light for an hour before bed may prevent melatonin suppression, thereby allowing individuals to fall asleep more quickly and easily.
Improves Bipolar disorder – Preliminary research shows that blocking blue light may help stabilize mood for individuals suffering from some forms of bipolar disorder. According to Dr. Jim Phelps, this “dark therapy” works basically in the opposite way as light therapy for depression.
- Combats Macular Degeneration - Excessive blue light from sunlight may be one cause of age-related macular degeneration. This eye-disorder exists at the leading cause of blindness in the elderly.
Yellow lens are primarily used by drivers, bikers, boaters, and professional athletes.
