Blue Light: How It Affects Your Vision and General Health
These days, many people spend most of their time in front of computers, televisions, smartphones, and other digital devices. This means hours of exposure to blue light, which the natural filters of your eyes don’t provide enough protection against.
In this post, your trusted local optometry clinic discusses how blue light affects your vision and general health.
What Is Blue Light?
Different colors of light have different effects on the human body. For instance, blue wavelengths are beneficial during daylight hours as they improve your attentiveness, mood, and reaction times. However, they tend to be disruptive at night. The prevalence of digital devices, such as smartphones increases people’s exposure to blue wavelengths, especially after the sun has set.
How Does Blue Light Affect You?
Blue light is just below UV radiation, which is harmful to different parts of your body, including the eyes. Experts believe that blue light has similar adverse effects on the eye as UV. Eye care specialists suggest limiting the use of devices that emit blue light. To keep track of your eyes’ condition, make sure to get a comprehensive eye exam regularly.
Another thing that blue light can affect is your sleeping pattern. While everyone’s circadian rhythm differs, the average length is 24 and a quarter hours. People who stay up late have a slightly longer circadian rhythm. It means that blue light exposure can affect your sleep-wake patterns. Some studies suggest a connection between nighttime activities and health conditions, such as diabetes, obesity and heart disease.
Moreover, to keep your eyes protected against blue light at night, try to use dim red lights for night lights. Avoid using digital devices two to three hours before going to bed. If you work at night in front of computer screens, wearing blue-light blocking glasses may help.
