Why So Blue About Blue?

For those on computers, smartphones and other digital devices, blue light can play an important role in your life.

Blue light waves are among the shortest, highest energy wavelengths in the visible light spectrum. These “blue” wavelengths flicker more easily than longer wavelengths. This flickering creates a glare that can affect sharpness and clarity. This flickering and glaring may be one of the reasons for eyestrain, headaches, migraines, physical and mental fatigue and poor sleep patterns caused by many hours of sitting in front of a computer screen or other electronic device.

Overexposure to blue light may also cause oxidative damage to the back of the eyes which may increase risk of macular degeneration as we age. This is a concern especially in children who are starting on digital devices at a much younger age.

“…focus on preventative eye health….”
“.. providing quality, stylish eye wear….”
“…bring out the uniqueness in you.…”

But don’t feel blue about blue! There are now options to ease the strain of this blue light. Come in and we would be happy to discuss them with you!
