The matter of whether or not blue light blocking glasses are effective in remedying eye strain is still being debated. Those in favor purport that as a result of damage to the eyes caused by blue light coming from digital screens, blue light blocking glasses effectively reduce eye strain.
Meanwhile, others like the American Academy of Ophthalmology assert that you don’t need blue light blocking glasses or any other special eyewear for computer use. They reason that blue light from digital devices doesn’t lead to eye disease or cause eye strain.
Meanwhile, according to Harvard Health, studies show that blue light wavelengths suppress the body’s secretion of melatonin. Melatonin is the hormone that regulates your sleep-wake cycles. Essentially, these studies show that exposure to blue light may disrupt your body’s natural circadian rhythm.

Studies show that amber lenses are effective at preventing blue light from reaching the eye. Besides that amber lenses offer other benefits, some of which include:
- Improve sleep quality
