Before going into the working and efficacy of blue light glasses, let us see what blue light is and how it affects our eyes. Sunlight consists of different colors of light. Also, every color has its wavelength and energy. Blue light is a constituent of the visible light spectrum. This light can damage the skin in various ways but most impact occurs on the eyes. Besides, many devices such as computers, television, mobile phones, light bulbs are a source of blue light. Prolonged exposure to this light causes several effects such as headache, eye strain, fatigue, and blurry vision.
Anti blue light glasses have special lenses designed to block blue light from reaching the eye. These lenses help filter out these high-energy waves and prevent eye damage. Besides, these lenses have a subtle yellow tint but it is unnoticeable. This tint helps filter the harmful blue light waves.
Do Blue Light Glasses Prevent Eye Strain
Several reasons may cause eye strain, and one of them is blue light. Concentrating on a computer screen for too long can cause stress on the eyes and fatigue in eye muscles. Also, looking at a screen too closely can cause eye muscles to strain. However, there are various methods to avoid this stress on the eyes and potential damage. Remember to take a short break every other hour to relax your eyes. Moreover, you can dim the brightness of the screen to avoid overexposure to blue light.
Nowadays, it is common for people to use digital devices for 10-12 hours a day. This practice has severe negative consequences on eye health and vision. Blue light blocking glasses are one of the methods to avoid these side effects. The lenses used in these glasses reflect the blue light waves in another direction. It means that the light waves can not penetrate through the lens.
Effect of Blue Light on Eyes
Blue light can significantly damage the eye retina leading to blurry vision. This damage leads to an eye disease called age-related macular degeneration (AMD). If it goes untreated, it can lead to blindness and distortion of vision. So, it means that exposure to blue light has permanent effects on eyesight. In everyday life, this light can cause mild to severe side effects such as headache and migraines, fatigue in the eyes, and vision distortion over time.
Blue light glasses can lower the risk of these side effects by protecting the eyes from damage. However, there are other ways to save yourself from this harmful light.
Taking a break away from the screen for about 20 minutes can decrease stress on the eyes. Also, it helps the eyes take some rest and relieve strain. Besides, you can balance the contrast and brightness on your computer screen accordingly. Decreased brightness level helps lower your concentration and gives a calming feeling to the eyes. Moreover, you can zoom the screen to help lessen your focus on the computer screen. Reading small text needs more focus and attention, which puts additional stress on the eyes. So, these small changes can help keep your eyes healthy and free of strain during long work hours.
Even though there are various methods to protect the eyes, sometimes you may forget to take breaks. So, wearing anti-blue light glasses is the best way to ensure that this light does not reach the eyes. Also, these glasses can uplift your casual look and make you appear more posed.
