We live in a digital world where we spend nearly half of our time in front of a screen. Our lives have been made better and easier thanks to digital technology, but there are some drawbacks. The effect of light on our eyes is one of the most important factors to consider in this digital world.
White light contains all the wavelengths from red to blue. Blue light exists naturally because of the Sun and is also emitted from our digital screens.
Research shows that light from 300 to 400nm wavelength is safe for our cornea but as it reaches 415-455nm, it becomes extremely harmful and toxic for our eyes.
Light exposure to such wavelength is okay but excessive exposure causes serious complications like headache, eye strain, eye tears, and sleeplessness. Blue light glasses are a safe and fashionable way to safeguard your eyes by limiting the penetration of those short wavelengths.
Here is what you need to know about the radiations and your eye health
What Do Blue Light Glasses Do?
Blue wavelength rays are blocked from reaching your eyes, protecting them from toxicity. Blue light rays decrease the generation of melatonin because they are high-energy rays.
Melatonin is created in response to darkness in order to maintain our sleep-wake pattern in tune with the rest of our lives. It’s necessary for healthier sleep.
Blue rays decrease melatonin synthesis, resulting in insomnia and other vision problems. The melatonin-suppressing effects of blue light are eliminated when you wear blue light spectacles.
This in return improves the quality of sleep and overall health of our eyes. You can shop for better quality glasses at Vision Direct to protect your eyesight from harmful rays.
Blue Light Is Not Evil At All
You are about to hear a lot of disadvantages of blue light, but it’s also wise to note the benefits. For instance, some blue light absorption is important for our general health. Blue light has been shown to control circadian rhythm (the body’s wake and sleep cycle), help neurocognitive performance, improve memory, and improve mental health, according to research.
Melatonin synthesis is only affected by extensive exposure to blue light. To put it another way, entirely shutting out blue light isn’t something we should aim for.
While it is feasible to wear your blue light glasses at all hours of the day and night, it is preferable to adopt a more balanced approach to the issue.
Other Techniques for Avoiding Eye Strain
The following are some eye strain prevention measures recommended by science:
- Keep an arm’s length away from monitors, or about 20 inches.
- Look down at the computer screen.
- If your eyes are dry, use rewetting drops to increase moisture.
- To make it more pleasant to look at, modify the illumination and the contrast levels of the display.
- If necessary, use a matt display filter.
- If an ophthalmologist has recommended glasses, use them when using a screen.
Final Thoughts
With more digitalization, we are spending more time in front of the screens than we should, we work in front of a screen, then we spend our leisure time in front of the TV or on our Mobile phone, everything includes a screen.
We shall limit our screen time as well as use blue light glasses to keep our eye health in check. People who spend more time in front of screens face issues like headaches, eye strain, stress, and also major psychological issues.
You can protect yourself from these issues by using glasses, staying at a safe distance, and by using other remedies for protecting your eyes.
