WHAT ARE SCREEN GLASSES?

Screen glasses (also known as blue light blocking glasses) are eyeglasses designed to reduce the amount of blue light that reaches your eyes from digital screens, such as those on smartphones, computers, tablets, and TVs. Blue light is a high-energy visible (HEV) light that is emitted by these devices, and prolonged exposure has been associated with digital eye strain, discomfort, and possible disruption to sleep patterns.

Key Features of Screen Glasses:

1. Blue Light Filtering: The primary function of screen glasses is to filter out or block a portion of the blue light emitted by digital screens. Some lenses have a special coating that absorbs or reflects the blue light.

2. Reducing Eye Strain: By blocking blue light, screen glasses can reduce the symptoms of digital eye strain, such as dryness, fatigue, blurred vision, and headaches.

3. Improved Sleep: Exposure to blue light, especially before bedtime, can interfere with the production of melatonin, the hormone that regulates sleep. By blocking blue light, these glasses can help maintain healthy sleep patterns.

4. Anti-Glare and UV Protection: Many screen glasses come with additional features, such as anti-glare coatings, UV protection, or anti-reflective coatings, which help reduce glare from screens and prevent UV radiation from affecting the eyes.
