BLUE LIGHT FILTERING GLASSES
Eyes are the windows to our soul. What we see we perceive. As such it is very important to take good care of our eyes. How? By having good knowledge of what is harmful to our eyes and what isn’t.
Just like our skin, the cells in our eyes can be damaged by UV light. Fortunately, our eyes have evolved to naturally block much of the UV light they’re exposed to. Sunglasses block what’s left when we are outside.
Ultraviolet light isn’t the only type of light that damages our eyes. We see things because the wavelength that makes up the visible portion of the electromagnetic spectrum get through our eye’s natural protection and reach the retina. It is discovered that the highest energy wavelengths of visible light can cause similar damage to our eyes just as UV lights. Blue light is the highest energy visible light (HEV). Ah, here it is the reason behind your tired eyes! Read more to learn…
Blue light is all around us. It is emitted by the sun and artificial light sources, including digital screens such as your smartphone, tablet, computer, and others.
It is seen in studies that blue light in moderation is necessary for regulation of the sleep/wake cycles of our body even it helps in our mood and cognitive performances.
It is also seen premature aging can happen because of the blue light. Overexposure to blue-violet light can damage the retina and subsequently increase the risk of age-related macular degeneration.
So, not all bad, eh? We need some amount of blue light. But with the recent times with the boom in the electronics uses it is very important to take precautions. It is better to remain in the safer side than repent later.
- sore or tired eyes
- stiff necks.
Do you have any of those? You definitely need to take care of your eyes.
Just like sunscreen and sunglasses, blue light glasses are specially designed to protect our eyes from the harmful affects of blue light. They are scientifically made to allow the wears to feel no difference than looking through any ordinary glasses. These glasses are good for indoor settings. Let’s here discuss how they work.
To be specific not all blue light glasses are of the same quality. It is understood different brands will use different coatings and materials the effect price, effectiveness, and general comfortability. Features that determines the validity and effectiveness of any blue light glasses are:
- How much blue light is blocked
- Anti-reflective coating
- Lens material
- Warranty options.
Multiple layers of special coatings are “baked in” to the lens. Each coating or layeradjustshow the light is transmitted or reflected. The particular coatings used in blue light glasses are engineered to absorb or/or reflect a very specific range of wavelengths that scientists have found to be most harmful (380 nm – 450 nm).
To lessen the colour distortion, a good pair of blue light glasses must allow all visible light wavelength to pass through, except the most harmful ones.
As mentioned earlier, different brands have their own features to block different degrees of blue light, ranging from as little as 10% to over 90%.
Blocking blue light have essential physiological benefits lenses that block about 60 to 30 percent blue light are perfect to be used by average users as well.
People with especially strong sensitivity to light can benefit from glasses that block more than that percentage. Anyhow if one feels more sensitivity to light, one needs to speak to their eye doctor.
Tip: Look for blue light glasses that block more than 50% of blue light.
An anti-reflective coating (a.k.a. AR coating or anti-glare coating) is a particularly important component of how blue light glasses work. Glare is one of the most common causes of eyestrain, and digital devices have prominent reflective surfaces that compound the issue.
AR coatings minimize the amount of light that’s reflected away from the eye, allowing more light to transmit through the lens. Doing so reduces distracting glare while increasing contrast for a better, less-straining experience.
Tip: Always look for blue light glasses that have an anti-reflective coating.
If we look back, we can see that eye lens glass has come a long way. Once they were made of dangerous and heavy glass. Today, there is a plethora of lens materials available. Each one has its pros and cons. But more than cons today they have become much better.
Weight and optical clarityaffect how comfortable our glasses are to wear throughout the day. Some are durable and others are less durable. It all depends upon the wearer what he is looking for.
It is logical the best lenses for computer glasses should be the least distracting that is light weight and with the highest optical clarity that is the least colour distortion and reflection.
Tip: We’ve tested and studied the most popular lens materials and found that Trivex and Nylon lenses are the best options for computer eyewear.
In a digital world that won’t seem to never slow down and the exposure to the blue light is unavoidable, it may be beneficial to own a pair of these specs if we spend a significant amount of time at a computer.
After researching available options based on the criteria above, we have partnered with the best manufacturers of lenses Essilor and Hoya to supply us the best lenses for your needs.
