Blue Light Dangers

Just as ultraviolet light at the high energy end of the light spectrum does a lot of damage, so does the blue light near the high end. Your University Vision Center El Paso TX optometrist wants you to know why blue light is harmful and how eye care in addition to optometry can mitigate the damages.

Why Does Blue Light Matter?

The colors in the visible light spectrum are long or short. Red light rays, for example, are long while blue light rays are short. The energy each expends affects us in different ways. Since the short blue light rays are closer to the invisible and stronger end of the light spectrum, they can damage us. It isn't uncommon for those who use computers, for example, to require eye surgery at some point while paying numerous visits to the eye doctor. How does blue light hurt the eyes?

Blue Light Is Bad

Every eye doctor and optometrist has warned that electronics emit blue light. However, no one can stop noses being buried in smartphones, tablets, and computers. Each wavelength of color in the light spectrum penetrates a certain layer of the eyeball. Blue goes through all the layers to the retina, where vision is permanently damaged.

Other Blue Light Concerns

The body's circadian rhythms dictate when we sleep and awaken. Blue light, also found in sunlight, tells the body it's not time to sleep, even if it's midnight. Any eye doctor will tell patients to turn off the phones, TVs, and computers two to three hours before bed as an aid to eye care.

What You Can Do

To prevent damages to the layers of the eyes, so you don't require eye surgery, and to restore normal circadian rhythm function, optometry professionals suggest wearing special anti-blue light glasses and not using electronics two to three hours before bed. Some people take their electronics to another room before bed to avoid the temptation of using them. Your University Vision Center El Paso TX, professionals will be happy to tell you about blue light when you call to learn more about it.
