Everything You Need to Know About Blue Light Glasses
Sunlight contains a lot of different colours. This can include indigo, blue, green, orange, yellow and even violet. Each colour has a different energy level, as well as a different wavelength. When all of these lights combine, you then have white light. This is otherwise known as sunlight. Blue light is within this spectrum.
It has a very short wavelength, but it has a high energy level. Blue light can be emitted from a range of different light sources, even though the largest is the sun, it also comes from digital screens. Smartphones, computers and tablets all emit strong levels of blue light, and if you spend a lot of your time sat at a screen then you may be concerned about how much exposure you are getting.
It may be that you are compromising your eye health, your brain activity, neural activity and more. If this leaves you feeling anxious, blue light glasses could help.

Animal studies have shown that blue light damage can lead to phototoxic retinal damage. It’s known that blue light can impact your eyes in many different ways. Patients have reported that they have additional eyestrain and that they also experience pain around the eyes if they do have too much exposure. Headaches, fatigue and even pain around the eyes can also be a sign. Another damage of blue light is that it can impact your circadian rhythm. This is essentially your sleep/wake pattern.
How can you Stop Blue Light from Affecting your Body?
There is a lot that you can do to try and limit your blue light exposure. For children, it is recommended that they do not get over an hour of screen time from electronic devices.
