Blue light lenses block blue light to minimize its impact on your circadian rhythm, which is particularly important for those who spend a lot of time using digital screens or in LED-lit rooms.

Blue light glasses are largely marketed as a solution to eye strain and as a protectant for the retina. Their effectiveness is not backed up by the science, however. While they are successful in blocking blue light, blue light is not necessarily something that needs to be filtered out for ocular health.

Blue light glasses have a special anti-reflection filter. This is designed to reflect a portion of the high energy blue light emitted by mobile phone and tablet screens, computers, and some televisions. The lenses are almost completely clear but have a very faint residual tint.

By selectively blocking harmful blue light and ultraviolet rays, blue blocking and UV protective lenses help prevent the early occurrence of certain eye diseases. Blue light is part of the visible light spectrum and is emitted by the sun and artificial light sources such as LEDs, computers, and smartphones.

Blue light glasses are safe to wear all the time, but it's important to consult with your eye doctor before introducing blue light glasses into your routine. Your eye doctor can help you select a pair of good quality and well-fitting glasses for your specific vision and lifestyle needs.

For many years, blue light blocking glasses have also been thought to help with headaches, eye strain, dryness, and blurred vision. However, newly published research suggests that they actually aren't effective at reducing headaches and other symptoms related to digital eye strain.

And the simple answer is, yes. Blue light glasses will not affect or damage your vision if you're wearing them throughout the day time or outside. However, it's important to note, that blue light in its natural form is actually a good thing and can be found in the sun's rays.

It works by only presenting the image intended for the left eye while blocking the right eye's view, then presenting the right-eye image while blocking the left eye, and repeating this so rapidly that the interruptions do not interfere with the perceived fusion of the two images into a single 3D image.

Yes, they are a great way to help improve vision for your night driving. They reduce eye strain and glare while allowing you to focus on the road better. Blue light glasses could be advantageous for improved sight and comfort when driving at night.

Wear Your Blue Light Glasses as Much as You Want If you feel blue light glasses reduce your eye strain or help you function better in front of a digital screen, then you can wear them whenever you want for a long as you want.

And a new review of 17 studies adds to a growing consensus that they probably don't prevent or relieve eye strain. The phrase blue light refers to a range of wavelengths of light that are all around us - the sun emits it and so do screens.

However, no significant improvement in vision performance or sleep quality has been found from using blue-blocking lenses.
