Blue light can be found everywhere, from sunlight and artificial lighting to TVs, computer displays, smartphones and tablets. Many studies have found this short wavelength within the visible light spectrum to be good for your eye health. Overexposure to it, however, can have a negative effect on your eyes.
Your local eye doctor from Northern Virginia Doctors of Optometry discusses how blue light affects the eyes in a bad way.
Digital Eye Strain
Blue light emitted from screens of computer displays and digital devices like smartphones and tablets is rather small compared to that coming from the sun. Still, you may be at risk of suffering from its negative effects, especially when considering the length of time you look at screens and how close you are to them.
Indeed, overexposure to blue light can cause digital eye strain. Also known as computer vision syndrome, it involves symptoms, such as fatigued and dry eyes as well as headaches. Apart from long screen exposure, computer vision syndrome is also a result of bad lighting and poor posture when doing work in front of the computer.
Fortunately, it can be alleviated through the use of computer eyeglasses. Doing eye exercises like the 20-20-20 rule and blinking more often during breaks have also been deemed important in relieving symptoms.
Damage to the Retina
Another negative effect of blue light on the eyes involves damage to the retinal cells, resulting in various vision problems that affect the retina. One of them is age-related macular degeneration (AMD). This is an eye condition where one’s central vision gets blurred while peripheral vision remains the same. The macula, or the sensitive part of the retina, gets damaged and may cause vision loss if left untreated and unmanaged.
