While it is true that sunlight is the primary source of blue light, experts say that you still absorb blue light even if you’re indoors. Blue light from artificial lighting, computer monitors, televisions, and smartphones enter your eyes easily. Also known as high-energy visible light (HEV), blue light from the sun and your digital devices can affect your health. Blue light blocking glasses have special filters that absorb or inhibit blue light. With the help of these glasses, you can prevent the harmful effects of overexposure. In case you are uncertain if blue light glasses truly work, here is some information you should consider.
Prevent Eye Strain
Medical research substantiates that extended exposure to blue light can cause lasting eye damage. You may already be experiencing digital eye strain from being in front of your computer screen for hours each day. Your discomfort worsens when you use your gadgets, watch TV, or read your book under artificial lighting.
Studies show that the cornea of your eyes isn’t efficient in filtering out blue light. Because of this, your retina receives blue light continuously, damaging light-sensitive cells. Eye experts say that HEV light has a short wavelength. It is difficult to focus because it disperses in your eye and lowers contrast. As your exposure lengthens, your eyes start to tire and your vision blurs or doubles. You can also develop headaches and eye pain. Blue light glasses can prevent all this from happening, if you wear them while you work, study, or go out for a walk.
Fights Age-Related Macular Degeneration (AMD)
Studies establish that AMD is one of the main causes of blindness in the United States. Wearing blue light glasses helps battle this eye condition by reducing AMD symptoms like blurred vision.
Ophthalmologists explain that melanin is also in your eyes. This pigment absorbs blue light and UV light at the same time. If you have more melanin, your eyes can have more protection from blue light. As you age, you lose melanin. This makes you susceptible to acquiring eye diseases such as AMD. By wearing blue light glasses, you can protect your eyes from absorbing blue light and accelerating the development of AMD.
Helps Improve Your Sleep
Authorities on sleep state that blue light helps regulate your sleep-wake cycle or your circadian rhythm. Your body uses this cycle to know what time to sleep and what time to wake up. Scientific journals corroborate that blue light increases your wakefulness and energy levels. This may sound good, but if you use your gadgets or watch TV before bed, falling asleep becomes difficult. Blue light tends to disrupt your natural sleep cycle. If you wear blue light glasses, your body can produce melatonin and signal your body that it’s time to get some sleep.
