Blue Light Awareness & Blocking
The light emitted by the plethora of digital screens that fill our daily lives is actually bad for us physically. They are the main source of harmful blue-violet HEV light. We are constantly exposing ourselves to this unnatural blue light from phones, computers, tablets, and televisions. SPEX Eye Care in Seattle and Bellevue can help you limit the amount of this blue light that enters your eyes by helping you find blue light blocking glasses that fit your style and needs.
What is Blue Light (HEV)?
Blue light is High Energy Visible (HEV) light, the harmful part of the light that digital screens emit. Visible light is in wavelengths of 380 to 700 meters with HEV light being between 380 and 500 nanometers.
Younger people who are exposed to excessive amounts of blue light have been shown to begin experiencing the signs of macular degeneration at an earlier point than others. In addition, there is research to support the claim that excess exposure to this light is the primary cause of vision loss for those over the age of 50.
As we spend around ten hours on average every day with digital screens, our exposure to blue light is growing. It is important to take steps to limit the damage this does.
Symptoms of Blue Light Fatigue (Digital Eye Strain)
Blue light fatigue is also known as digital eye strain or computer vision syndrome. It causes stiff necks, tired burning eyes, and headaches. The light also causes eyes to work harder and thus, puts them at risk of faster aging. Our eye doctor is trained to recognize this condition and help you overcome it.
How to Protect Your Eyes
Blue light blocking lenses are specially designed to filter out a substantial portion of the damaging blue-violet light of digital screens. They make screen time less damaging and more comfortable while reducing digital eyestrain. Our optometrist can help you combat blue light.
