Spend more time tweeting and texting. No doubt, these technologies (TVs, PCs, Tablets, and Smartphones) ensure that the trying time was more bearable.

Unfortunately, many are unaware that these devices emit blue light which is likely to disrupt the sleeping order.

The purpose of this read is to enlighten our readers on the importance of blue light blocking glasses for people that can’t do without the aforementioned devices.

What are Blue Light Glasses?

The blue light glasses are special eyewear purposely designed to block out the blue lights emitted from the devices people use every day. These glasses possess surface coatings and other filtering properties on the lenses which block out the blue light to a certain degree.

The glasses are also suitable for people suffering from eye and vision symptoms because of their exposure to the emission of blue light. The blue light glasses can reduce their exposure to the blue light.

With that said, the emitted blue light is a short-wave blue light which is in varieties of color visible to the eyes. The range of the blue light is in the fragmentation of the electromagnetic spectrum. Which is approximately within the range of 400 to 500 nanometers (nm). It is believed that anything above 440nm could cause damage to the eye.

The Science Backing the Blue Light Filtering Glasses

A 2017 study carried out by the University of Houston shows that the blue light filtering glasses increases the melatonin levels of the participants in the night by 58%.

Another 2019 research has proven that blue light filtering glasses can be helpful in the treatment of sleeping disorders in people who have Parkinson’s disease.

According to Lisa Ostrin, a Professor at the University College of Optometry, the blue light blocking glasses can help in the improvement of sleep. Allowing people to continue using their devices.

With the blue light filtering glasses, you also get to be productive at night.

Effect of Blue Light on the Eyes

We must discuss some of the effects of the emission of blue in the eyes

Effect of Blue light on Cornea

The cornea is situated in the front end of the eyeball. This part of the eyes is the first to encounter the light when entering the eyes. However, the survival rate of the cornea epithelial cell after the blue light enters the eyes tends to decrease.

Effect of Blue light on the Retina

The retina is the first site of vision formation. It is also the lesion site of various eye-blinding diseases. When the blue light penetrates through the retina, it can cause retinal photochemical damages.

Effect of Blue light on the Lens

The opacity of the lens is one of the major causes of cataracts. The eye lens is a composite of enzymes, protein metabolites, and structural proteins, all of which absorb the blue light. However, when this absorption is constant and increases rapidly, the blue light resistance of the lens weakens.

Also, when the eyes are exposed to sunlight is another risk factor for cataracts. The blue light can produce reactive oxygen species in the mitochondria of epithelial cells of the lens. Which is likely to result in cataracts.

The Benefits of the Blue Light Glasses?

Now that you know some of the effects of the emission of blue light on the eyes. It is essential to discuss some of the benefits of blue light filtering glasses.
