If this sounds familiar to you, chances are you may be experiencing common symptoms of digital eye strain associated with prolonging blue light exposure.
Necessity to protect our eyes alleviates the symptoms and maintains our eyes healthy long-term.
According to the BrightFocus Foundation, as many as 11 million U.S. people currently have some form of age-related macular degeneration.
Worldwide, they expect it to affect almost 288 million people by 2040.
This number is expected to reach 22 million by 2050.
According to an article Indian Journal of Ophthalmology:
A total of 407 usable responses were obtained; the average age of respondents was 27.4 years.
Typically, 93.6% of respondents reported an increase in their screen time since the lockdown was declared.
The average increase in digital device usage was calculated at about 4.8 ± 2.8 h per day.

| Screen Time |
The total usage per day was found to be 8.65 ± 3.74 hours.
Sleep disturbances have been reported by 62.4% of people.
Typically, 95.8% of respondents had experienced at least one symptom related to digital device usage.
56.5% said that the frequency and intensity of these symptoms increased since the lockdown was declared.

Lets answer this one-on-one:
Blue light is part of the visible light spectrum (380 to 500nm range).
About one-third of all visible light (spectrum) is considered high-energy visible, or “blue,” light.
Artificial sources of blue light include fluorescent light, CFL bulbs, LEDs, LED televisions, smart phones and tablet screens.
Are there any Health Benefits Of Blue Light?
According to Heath Canal,
Blue light boosts alertness, helps memory and cognitive function, and elevates mood.
Inadequate exposure to blue light can also contribute to the recent increase in myopia, or nearsightedness.
Even though Blue-light exposure from screens is minimal compared to the amount of exposure from the sun.
However, there is concern about Screen time and Screen exposure when is too closeto the eyes.
Scientists at the University of Toledo, may have discovered how blue light emitted from our technology has a potential to lead to macular degeneration — one of the leading causes of vision loss.
Macular degeneration is the result of photoreceptor cell death in the retina.
The function of the photoreceptor cells is to capture visual images.
When these photoreceptor cells die, there’s no regeneration.

Blue Light Isn’t the Main Source of Eye Fatigue and Sleep Loss!
According to Jstor Daily, Blue light has gotten a bad rap, getting blamed for the loss of sleep and eye damage.
Personal electronic devices emit more blue light than any other color.
Blue light has a short wavelength, which means that it is high-energy and can damage the delicate tissues of the eye.
It can also pass through the eye to the retina, the collection of neurons that converts light into the signals that are the foundation of sight.
When it comes to protecting our vision and keeping our eyes healthy, blue light isn’t your biggest concern.
Does Blocking the Blue Make Sense?
Based on research, in a nutshell, the answer is “no.”
The truth is that any bright light too close to bedtime interferes with sleep.
How?Blue light in the evening tricks your brain into thinking it’s daytime, which inhibits the production of melatonin and reduces both the quantity and quality of your sleep.
The leading blue-blocking anti-reflective coating blocks only about 15% of the blue light that screens emit.

You could get the same reduction just by holding your phone another inch from your face.
How Can I Reduce The Negative Effects Of Blue Light?
- Turn off your electronic devices before bed.
The American Academy of Pediatrics recommends that bedrooms be “screen-free” zones for children. - As for eye strain, ensure that you have the appropriate glasses or contact lens prescription.
Contact an optometrist or ophthalmologist can give you this information. - Follow the “20-20-20” rule: The American Optometric Association defines this rule as taking a 20-second break every 20 minutes to look at something 20 feet in the distance.
This will allow your eyes to blink and relax.
Conclusion:
Eliminating blue light alone doesn’t cut it when it comes to improving sleep, or eye strain.
Think twice before purchasing products you don’t need (blue-blocking anti-reflective coating glasses).
Instead, keep screens out of your sleeping hours and dim them before bedtime.
Best Advice: Keep your eyes lubricated. And don’t forget to blink!
