Do you think that blue light glasses work?
Blue light glasses are a necessity for all, whether you wear prescription glasses or not. This will help you to protect your eyes from the harmful blue light rays emitted from digital devices like laptops, mobiles, tablets pc and others. Using these devices for a long time leads to eye damage. It is our responsibility to protect the eyes from the harmful blue light rays emitted from the devices.
There is always a controversy where some say that blue light does not affect our eyes and is not harmful. Again some say that blue light is highly damaging and affects our eyes and vision in various ways. Thus there will always be controversy and debate on this topic. Avoiding all these, let us go deeper into the details of blue light glasses and understand the concept of blue light.
What is blue light?
Sunlight contains 7 types of light, red, orange, yellow, green, blue, indigo, and violet. Blue light has the shortest wavelength with the maximum energy. Thus its blue light is generally called visible light. Blue light is emitted from various sources, the sun being the largest among all and we get the most exposure to blue light to it.
However, there are also many man-made sources, and in recent years, blue light has gained notoriety because of its link to digital screens. Mobiles, tablets, laptops, and other digital devices are man-made sources that emit blue light. Although this is only a fraction of that emitted by the sun, the amount of time people spend using these devices and the proximity of these screens to the eyes has raised concern about the potential long-term effects of blue light on eye health.
How do blue light glasses affect our eyes?
Since blue light has a short wavelength, it can penetrate the eyes very easily. All blue light rays can pass through the cornea and lens to the retina. It has been found in some research that too much exposure to blue light can damage the light-sensitive cells of the retina. One animal study also found that blue light damage may cause phototoxic retinal damage.
Digital devices indeed emit blue light, but more blue light is emitted from natural lights, like daylight. The risk of eye damage from blue light is significantly lower than that from sunlight. Thus neither of them approaches any safety limits for the eyes. Hence the potential of blue light emitted from the devices is very less than that of the other lights.
What are blue light glasses?
Blue light glasses have a special protective coating that helps to block the blue light from every possible source. These lenses are specifically designed to block the blue light from entering the eyes. The glasses filter the blue light and prevent them from entering the eyes and causing any damage. Usually, the blue light glasses have some yellow tints, to counterbalance the blue light. It is usually invisible to us.

The eyes need to be protected and blue light glasses help to do so. By blocking the blue light from penetrating through the glasses and entering the eyes, the blue light glasses protect the eyes.
Does blue light protect the eyes from digital strain?
When we continuously look at the screen, we experience digital strain. Our eyes feel fatigued, sometimes vision blurs, and sometimes causes headaches. This becomes very stressful and results in causing multiple diseases related to other parts of the body. This may not show the results immediately, but slowly it starts damaging our body.
