Light is a complex thing to understand. When you step outside to the sun, you flip a wall switch in your home, you turn on and use your computer, you check your mobile phone or tablet, or you watch TV, you are exposing yourself to various kinds of visible and even invisible rays of light.
These can have an effect on the body, which can either be good or bad, depending on the type of light.
Blue Light Effects
A recent study conducted by the lender of America confirmed that almost 50% folks consumers couldn’t live without their cellular devices even for per day. It really is indeed hard to withstand since the majority of us depend on smartphones to check emails, talk to our loved ones, and even read the news. But what most of us don’t know is that the blue light emitted by our precious devices can harm our vision – and in the long run, it could even have a negative impact on our health.
Continual exposure to blue light when looking at our devices can affect our eyes mainly in two ways:
1. Digital Eye Strain
This the most common side effect of extended device use. Looking at the display means our blink rate reduces and this causes eye strain. Symptoms include dry, runny, and/or tired eyes. This problem is temporary, but it can become chronic if unaddressed.
2. Permanent Eye Damage
This appears like a significant problem since it is. Blue light is precisely what you believe that it is: light that emits a blue color. And that is evidently a harmful kind of light since it gets the highest energy wavelength out of most types of noticeable light. Blue light may also penetrate to the trunk of the eye, completely the natural filter systems of our eye. Over time, this could contribute to Eye diseases, including macular degeneration.
Fortunately, there are ways to resolve both of these eye problems. To get started with, since digital Eye strain is caused by reduced blinking, the perfect solution is to blink more. This will keep the eyes lubricated. Another method is to apply the 20-20-20 rule where you stare at something that’s at least 20 ft away for 20 mere seconds every 20 minutes. For the second one, the perfect solution is simple: cut back on your use of devices, especially at night.
Talk to an eye doctor as well to get lenses that can filter out blue light. By doing these simple solutions, you can protect your eyes, keep them healthy, and help them last longer than our devices.
