Are you feeling too much strain on the eyes?
Or,
After reading an article about harmful rays, are you just worried about your eyes?
We’ve all been through this, but the rookie mistake made is caused by confusion about the type of harmful light. This mistake might even lead to you buying the wrong pair of glasses.
Scroll through the article to learn about blue and UV light glasses and understand which one is right for you.
Definition
The blue light glasses are made to block out the blue light that is emitted by the digital screens, whereas the UV light glasses protect against the harmful ultraviolet (UV) rays.
Effects
The blue light emits from the screen and is usually visible. This light apart from causing damage to the eyes also causes sleeplessness if faced for long durations.
The UV light on the other hand cannot be spotted via the naked eye but is way more hazardous, not just to the eyes, even to the skin. This light is likely to affect the cornea and lens of the eye.
Benefits
The blue light glasses help in keeping our eyes calm, along with a night of better sleep and sleep time, whereas UV light glasses make the eye have better visibility.
Type Of Lens
The blue light glasses protect with the help of a polymer layer, whereas the UV light glasses come along with a coating that protects most of the UV rays.
Usage
The blue light glasses can be used all time and are recommended the most while using gadgets like smartphones, computer screens, etc. On the other hand, UV light glasses are worn outside, especially on bright sunny days.
Invention-Related Facts
The difference between the invention of both the glasses is of more than 150 years! Fascinating, isn’t it?
The blue light glasses were recently invented by Johann Wilhelm Ritter in 1936, compared to the ages-old UV light glasses invented in 1784 by Benjamin Franklin.
Blockage Of Rays By Eye
The retina of our eye needs ultimate protection from harmful rays. Gladly, the cornea and lens of the eye do protect the retina and the back of the eyeball from UV rays, but it fails to do so in the case of blue light.
Harmful Nature
Blue light these days is unavoidable and without protection for our eyes, it might lead to blindness at a later stage of life. It is caused by long-term exposure to blue light.
Moving to the UV light is likely to cause cancers of the ocular adnexa, pinguecula, and photokeratitis. Long-term exposure to UV light can even cause cataracts.
Benefits of Lights
Apart from the harmful nature, there are a few benefits of these lights too.
Blue light:
- Better memory
- Improved moods
- Hike in alerting levels
UV light:
- Exposure to Vitamin D
- Hike in energy levels
- Better moods
Brownie Advice
The blue light glasses should be used for protection from artificial sources of light and should not be used to filter the sun’s blue rays as they might lead to disruption of your sleep and hormones.
Also, blue light is surprisingly used to treat seasonal affective disorder, which is a depression caused by seasonal changes.
Conclusion
Undoubtedly, both glasses have their own features and benefits, and the eye needs protection from both harmful rays. You can also try polarized glasses for more protection.
But, if you are a person who stays indoors most of the time and has a lot of screen time, you totally need blue light glasses, and if you are someone with a field job or have to stay outdoors for longer periods, you should go for UV light glasses. For more protection, you can wear sunglasses indoors too!
Make sure to buy both for the ultimate protection, so you can wear them at respective times when required.
