Blue light filter selection is complicated. A blue filter may help you with many problems: computer eye strain (computer vision syndrome), LED & fluorescent light sensitivity, sleep disorder, age-related macular degeneration (AMD), light sensitivity (discomfort glare), visual acuity… But not every blue filter will produce optimal results given the specifics of your blue light sensitivity problem. The chaos of hype marketing terminology often hides more than it reveals which further complicates the selection process. Read on to find out: which wavelengths your blue filter should absorb/block, by how much, how to compare bluelight filters…
Less light sensitivity, computer eye strain: BlueLight filtering diet
You can reduce computer eye strain and light sensitivity with diet! Light sensitivity and computer eye strain may be due to low macular pigment, your natural bluelight filter. Nearly 80% of Americans have this condition! Research shows that low macular pigment is associated with lower threshold of light sensitivity or discomfort glare (Enhancing performance while avoiding damage: A contribution of macular pigment; 2013). Moreover, since glare is a known computer eye strain cause (Computer vision syndrome: A review; 2014) low macular pigment, i.e. lower threshold to glare, may make you more prone to computer eye strain. Luckily macular pigment bluelight filtering capacity can be improved with appropriate fruit and vegetable diet or dietary supplements (Lutein and zeaxanthin dietary supplements raise macular pigment density and serum concentrations of these carotenoids in humans; 2003).
