How Do Prescription Glasses Filter or Block Blue Light?
Prescription glasses can filter or block blue light by incorporating special coatings or lens materials designed to reduce blue light exposure from digital screens and artificial lighting. This filtering can help alleviate digital eye strain and improve visual comfort.
The mechanisms by which prescription glasses achieve this include:
-
Coatings: Many prescription glasses come with an anti-reflective or blue light blocking coating. These coatings are designed to reflect or absorb blue light wavelengths while allowing other visible light to pass through. Research has shown that such coatings can reduce exposure to blue light by approximately 20% to 50% (Huang et al., 2019).
-
Lens Materials: Some lenses are made from materials that inherently reduce blue light emissions. For example, certain high-index lens materials can filter out blue light effectively. A study in the American Journal of Ophthalmology reported that specific lens types could block up to 35% of high-energy visible (HEV) blue light when properly designed (Peters et al., 2020).
-
Color Tinting: Lenses may also be tinted with a yellow tone. This tint can help block a portion of blue light, enhancing visual contrast and comfort during prolonged screen use. A study indicated that yellow-tinted lenses can provide a subjective visual comfort improvement while reducing the impact of glare (Lee et al., 2021).
Through these methods, prescription glasses serve not only to correct vision but also to provide additional protection against potential visual fatigue and disruption caused by excessive blue light exposure.
What Are the Health Benefits of Using Blue Light Blocking Prescription Glasses?
