People spend many hours using digital devices, such as television screens, tablets, and phones. Adults spend more than six hours staring at screens every day, while teenagers take around seven hours daily.
Apart from physiological and musculoskeletal problems, blue light harms your eye health. Below are the benefits of using blue light glasses compared to regular ones.
Improves The Quality Of Your Sleep
Blue light is emitted by fluorescent lighting, digital screens, and sun rays. That coming from the sun has more energy and shorter wavelengths. Exposure to it when outdoors makes you more alert. In the same way, too much screen time before your bedtime makes it hard for you to sleep immediately.
The short wavelengths in the blue light delay the release of a hormone called melatonin, which helps induce sleep. If you cannot stop using your devices an hour before your sleeping time, it is ideal that you get blue light glasses. Unlike regular glasses that cannot block the wavelengths that affect sleep, they can help you sleep better than before.
Staring at your screen for a long time can strain your eye muscles. Blue light is not easily focused because it scatters with more ease than other types of visible light. When you spend many hours using a digital screen, the visual from the blue light contributes to your eyestrain by reducing contrast.
Research shows that blue light glasses are different from regular glasses. They significantly increase the contrast, thus reducing eyestrain.
Research shows that blue light can worsen headache pain. It increases muscle tension and throbbing. Using blue light glasses helps block all types of light wavelengths except the ones from green light when you have a headache or migraine.
Regular glasses can let in blue light wavelengths, which will make the headache worse. Some patients report a reduced light sensitivity when wearing blue light glasses.
Reduces The Chances Of Getting Eye Diseases
Your eye lens and cornea can block out the harmful ultraviolet rays from reaching your retina. However, they cannot do so for blue light. When your retina gets damaged, you have a heightened chance of getting macular degeneration or cataracts. Such conditions can make your eyesight worse and even lead to vision loss.
Wearing blue light glasses helps protect your retina and the structures of your eyes from damage, unlike regular glasses. As a result, you reduce your risk of eye diseases.
Reduces Dry Eyes
Spending long hours using your phone, computer, or tablet can reduce your blinking frequency. You will stare for a long time and not blink as often as you should. The blue light emanating from the screens also increases eyestrain, which results in your eye becoming dry due to the lack of enough lubrication. You are likely to experience these symptoms:
- Scratchy, burning, or stinging sensation in the eyes.
- Eye redness.
- Stringy mucus in your eyes.
- Difficulty wearing contacts.
- Difficulty driving at night.
- Eye fatigue.
- Watery eyes due to irritation.
- Blurred vision.
Wearing blue light glasses will filter the light causing your eyestrain. Doing so will help protect you from dry eye and blue light.
