Blue-light-blocking glasses are said to help reduce eye strain and headaches — are they for you?
See explains. "As we get older, our lenses are less flexible. This is why people in their 40s start needing reading glasses. Some blue-light glasses also include a plus lens to help bring your ...
A study sponsored by the lens industry has shown blue light-filtering lenses decrease specific aspects of light emissions. Theoretical reductions in phototoxicity were 10.6% to 23.6%. [12] Additionally, melatonin suppression was reduced by 5.8% to 15.0% and scotopic sensitivity by 2.4% to 9.6%. Over 70% of the participants in this testing were ...
Prolonged exposure to blue light poses hazards to the well-being of the eye and may cause symptoms like dry eyes, weariness, and blurred vision. As our dependence on digital devices and artificial lighting increases, the complex pathways of the blue light spectrum that affect biological processes is crucial to understand.
Blue-light-blocking glasses claim to reduce eye strain from devices, but scientists say there are better ways to reduce the strain on eyes.
Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
Blue light has also been blamed for eye strain and discomfort. As a result, people have been shelling out for blue light-filtering spectacles in hopes of snoozing in peace and reducing visual fatigue.
Eye strain, also known as asthenopia (from astheno- 'loss of strength' and -opia 'relating to the eyes'), is a common eye condition that manifests through non-specific symptoms such as fatigue, pain in or around the eyes, blurred vision, headache, and occasional double vision. [1]
