NAKED EYES ARE NOT DESIGNED TO STARE AT DIGITAL SCREENS AND ARTIFICIAL BLUE LIGHT
I developed serious "dry eyes" and eyestrain from working a computer for 10+ hours a day.

My optometrist suggest " computer glasses " by the leading manufacture in the field GUNAR
I felt immediate relief and now I make the Gunar glasses a part of my day. They are truly effective

It is summed up perfectly on their website:
" GUNNAR is the only patented computer eyewear recommended by doctors to protect and enhance your vision. GUNNAR’s premium computer eyewear defends eyes against short and long-term effects of digital eyestrain. Our patented lenses add focus, block harsh blue light and glare so your eyes can finally relax. Focus longer. Work more efficiently. Be comfortable doing it."
