Blue light glasses feature specially designed lenses that filter or block a portion of the blue light spectrum. They typically block high-energy, shorter-wavelength blue light in the range of 380 to 500 nanometers. By reducing exposure to blue light, blue light glasses can help reduce eye strain and discomfort caused by prolonged screen time. They can alleviate symptoms like dry eyes, blurred vision and headaches. So it has unparalleled strengths compared with normal glasses.
Blue light glasses work by incorporating special lenses that are designed to filter or block a portion of the blue light spectrum emitted by digital screens, artificial lighting, and other electronic devices. Here's how they work:
1.Blue light spectrum:
Blue light is a component of the visible light spectrum, and it has a relatively short wavelength and high energy. It is emitted by various sources, including digital screens, led and fluorescent lighting, and the sun.
Blue light glasses feature lenses that are coated with a filtering material. This coating is typically applied to the front surface of the lenses.
3.Blue light absorption:
The coating on the lenses is designed to selectively absorb and block a specific range of blue light wavelengths, typically in the range of 380 to 500 nanometers. This range includes the most harmful and high-energy blue light.
4.Transmission of other light:
While blue light is blocked or reduced, blue light glasses allow other wavelengths of visible light, including green, yellow, and red light, to pass through the lenses. This means you can see clearly without a significant color distortion.
Blue light glasses do not block all blue light, as some blue light wavelengths are essential for our overall vision and well-being. They are designed to selectively filter out the most harmful and high-energy blue light while allowing other light wavelengths to pass through, maintaining visual clarity and comfort.
Blue light glasses have become popular due to increased screen time and concerns about the potential effects of prolonged exposure to blue light from digital devices.

Some blue light glasses with strong filters or heavy tinting may also purpose moderate color distortion or a yellowish tint, which could affect the manner you understand hues.
Blue light glasses, specially thoses with specific coatings or functions, may be more highly-priced than normal eyeglasses. But they're usually lower priced than prescription glasses.
Poorly fitted or low-first-rate blue light glasses may be uncomfortable to put on for prolonged intervals,main to soreness or pressure at the nose and ears.
It depends on your lifestyle, habits any symptoms you may be experiencing related to digital screen use.
1.Prolonged screen time:

If you have irregular sleep patterns or frequently work night shifts, blue light glasses in the evening can help minimize the disruption to your circadian rhythm.
8.Preexisting eye conditions:
If you have existing eye conditions like dry eye syndrome or digital eye strain, blue light glasses may be recommended by your eye care professional as part of your eye care routine.
