From checking emails on your computer to scrolling through social media on your phone, you might spend several hours each day looking at screens. Electronic devices with screens emit blue light, which consists of rays that have shorter wavelengths and more energy. While using these devices, the eyes absorb blue light, which may adversely affect your vision and health. Fortunately, glasses with blue light lenses have special filters that may provide protection. Here's why many optometrists recommend wearing them.
Reduce Digital Eye Strain
Digital eye strain, also known as computer vision syndrome, is a condition that may occur due to prolonged use of devices with digital screens. Blue light reduces contrast on screens, causing eyes to work harder to focus and resulting in symptoms such as blurry vision, headaches, and eye dryness. The glare produced by blue light may also cause the eyes to strain and produce these uncomfortable symptoms.
Prescription glasses that block blue light have a yellowish tint that increases contrast on screens and anti-reflective lenses that reduce glares, which can relieve symptoms of digital eye strain.
Get Better Sleep
Melatonin is a hormone the brain produces and releases into the bloodstream, promoting feelings of sleepiness. Exposure to blue light can inhibit melatonin production, which may make it difficult for you to fall asleep and lead to insomnia. Glasses with blue light lenses block out excess blue rays. This can help your brain produce more melatonin, allowing you to get more restful sleep. You may also promote a good night's sleep by ceasing device use about an hour before bedtime.
