People are spending more time than ever looking at different digital screens, such as televisions, computers, and smartphones. In addition to physiological and musculoskeletal issues that can result from too much screen time, blue light can harm your eyes.
In addition to the blue light emitted by digital screens and fluorescent lighting, you will find it in the sun’s rays as well. The sun’s rays contain all colors, including blue, green, orange, and red. Each of these colors radiates different energy levels. On one end of the spectrum, blue light has more energy and shorter wavelengths. Red light, on the other hand, has less energy and longer wavelengths.
Experts are yet to confirm whether wearing blue light glasses can help protect people’s eyes from potential damage due to long-term exposure to blue light. According to manufacturers of blue light glasses, however, they can filter out blue light. These glasses have surface coatings or filtering materials on the lenses designed to block a portion of blue light.
If you suspect that your vision and eye symptoms stem from blue light exposure, you should consider wearing blue light glasses to minimize your exposure. Symptoms and signs of digital eye strain include headaches, dry eyes, and blurry vision. Most blue light glasses feature non-glare protection as well. Even if you do not have a prescription, you should consider wearing them to enjoy the following benefits:
Looking at a digital screen all day can stress your eyes. It may lead to muscle and eye strain. Ergonomic adjustments can solve the muscle problems associated with sitting in front of a digital screen for many hours. When it comes to reducing eye strain, however, blue light-blocking glasses are your best bet. They help increase contrast on the screen, which makes it easier to focus.
Your eye lens and cornea block out most of the harmful UV rays from reaching your retina. Unfortunately, they are not effective when it comes to blocking blue light. Any damage to your retina can increase your likelihood of developing certain eye diseases, such as macular degeneration. Blue light can even breach your retina, which may increase your risk of getting cataracts. Wearing blue light-blocking glasses can reduce the risks.
Spending a lot of time in front of a screen before bed will make you feel more alert. But, unfortunately, this delays the release of melatonin, a sleep-inducing hormone that starts releasing about two hours before bedtime. This delay will make it more difficult to fall asleep quickly. If you cannot avoid spending time in front of a digital screen before bed, wearing blue light glasses may be a good idea.
Blue light can trigger and exacerbate headaches and migraines. Using these glasses to block blue light may reduce headaches and migraine attacks.
If you want to avoid most of the problems associated with blue light, limit your use or step away from your digital devices. If you are unable to take such measures, consider using blue light glasses. With these glasses, you will not need to make drastic changes to your lifestyle.
