FAQs about Anti-blue Light Glasses

Nov. 30, 2022

Anti-blue light glasses are becoming increasingly popular because of their ability to reduce eye strain. Even though there have been some studies that show that blue light filtering glasses can protect your eyes from blue light that can damage your retina. But for people who are considering whether to invest in a pair of anti-blue light glasses, there are still many questions. This article will answer some of the most frequently asked questions about anti-blue light glasses.


Anti-blue Light Glasses


1. Do anti-blue light glasses really work?


The answer is yes. Blue light lenses do help prevent blue light from digital screens from entering your eyes, which can help prevent or alleviate some of the discomforts you may experience from prolonged exposure to digital screens.


2. Can anti-blue light glasses hurt my eyes?


Blue light is a type of harmful light emitted by electronic devices such as tablets, smartphones, and laptops. Anti-blue light glasses not only won't hurt your eyes, but they can also protect your eyes from blue light.

3. How can I tell if the lenses have blue light protection?


Anti-blue light glasses are an added feature to your eyeglasses, and if you don't specifically request them at the time of purchase, your lenses may not have blue light protection.


4. Can anti-blue light glasses relieve eye fatigue?


Because prolonged viewing of digital screens can cause eye strain, wearing anti-blue light glasses alone is usually not enough to prevent eye strain. Although there is no conclusive evidence that blue light-blocking glasses can prevent eye fatigue, most users have reduced eye fatigue when using electronic devices.



5. Can blue light glasses relieve headaches?


Headaches are a common symptom of eyestrain, which is caused by prolonged viewing of digital screens. Although blue light glasses do not completely prevent digital eye fatigue, when wearing blue light glasses and using digital devices, anti-blue light glasses may reduce some of the light reaching your eyes, thus reducing eye fatigue. So, if you get frequent headaches when using electronics, then blue light glasses may be worth a try.


6. Can anti-blue light glasses improve sleep?


A study published in the Chronobiology International Journal in 2021 showed that using anti-blue light glasses before bedtime can improve sleep. This is because blue light affects the body's natural production of melatonin, a hormone that helps you feel sleepy.


7. Can I wear anti-blue light glasses all day? 


Wearing anti-blue light glasses for long periods of time will not have adverse effects. If you spend a lot of time in front of a screen, wear anti-blue light glasses throughout the day.


8. Do anti-blue light glasses help when driving at night?


Blue light glasses can reduce some glare from oncoming headlights, street lights, etc., and therefore can help users drive at night.
