Are Blue-Light Protection Glasses Worth It?
Whether you are working on your computer, or just soaking up some sunshine; you are due to be exposed to blue light. Some people believe it is not harmful, but in reality, blue light is very close to UV light on the visible light spectrum, meaning it can have a significant impact on your eyes. So, are blue light eyeglasses actually worth it? And what is the real effect of blue light on your eye health? Let’s discuss what our expert optical team has to say.
Blue light
Sunlight contains different types of colored lights such as red, orange, yellow, green, blue, indigo, and violet lights. Each of them has a specific wavelength and energy level, and if we combined the spectrum of colored light rays; we will get sunlight or white light.
So, blue light is only one type of spectrum of colored light rays. The danger of blue light is that it has a short wavelength, but a high energy level. Keep in mind that this blue light can be emitted from different sources. Of course, the biggest source is the sun, but there are human-made sources which we get our exposure from. Especially, in the last years, after the widespread of digital screens including computers and smartphones.
The big threat of blue light does not come from the sun, it is actually coming from spending too much time in front of our digital screens and smart devices. The damaging effect usually takes a long time to appear, and it’s permanently on your eye health.
The effect of blue light on the eyes
As mentioned above, a shorter wavelength of blue light makes it easier to penetrate your eyes. In other words, these blue light rays will reach your retina, which is in the back of your eye, passing through your cornea and lens.
The research found that there is a possibility of permanent damage to light-sensitive cells located in the retina after too much exposure to blue light. However, the blue light-emitting digital screens are usually lower than the natural sunlight. So, you need more time for any potential damage from the digital screens.
Blue light Protection glasses
Blue light protection glasses or blue light blocking glasses are normal eyeglasses that contain special lenses to block or reduce the amount of blue light passing through your eyes and damaging them. They usually come with unnoticed yellow tine that works on counterbalancing the blue light rays.
