Blue Light Exposure: How It Damages Our Eyes

Blue light isn't a term for those crazy lights found at parties. Blue light radiates from many of the devices you have in your own home that you may use every day. Unfortunately, this type of light has been linked to eye problems such as macular degeneration. 

Blue Light Dangers

Definition of Blue Light 

All light is made up of various colors including blue light. On the spectrum, blue light emits short wavelengths of light. Although it has short wavelengths, this form of light has high energy. 

All blue light doesn't appear as blue. White lights may consist of a high concentration of blue light. Ultraviolet light transmits the highest amount of energy and is more damaging than other forms of blue light. Blue light is found in sunlight, fluorescent lights, LED lights, flat screen LED televisions, tablets, smartphones and computer monitors. 

How Blue Light Damages the Eyes

The eyes don't filter blue light well. A majority of the blue light enters the eyes and passes through the lens and cornea. The blue light even reaches to the back of the eye where the retina is. This part of the eye is responsible for transmitting nerve pulses to the optic nerve in the brain. This particular area of the eye is sensitive to light.

Blue light transmits in scattered fragments, which makes it difficult for the eyes to focus on items that use this type of light. Consequently, the blue light emitted from a computer or cell phone screen is why people feel eye fatigue, eye pain or other symptoms of eye strain.

Blue Light and Macular Degeneration 

Several studies have linked an excessive amount of blue light exposure to an increased risk of age-related macular degeneration. The blue light causes changes in the sensitive cells in the retina. The changes ape the effects macular degeneration has on the cells. People who already have macular degeneration and are heavily exposed to blue light may potentially worsen their condition. According to the American Macular Degeneration Foundation, blue light and ultraviolet light may cause cataracts.
