I never had issues with sleep, but I work in the operating room doing 12 hour shifts. Under fluorescent lights looking at screens all day. My eyes get tired and I was getting headaches by midday.
I am definitely feeling a lot less ice strain at the end of the day..
My daughter insisted I get these glasses. I ordered a prescription pair and I can’t believe the difference! I wear them reading but especially when using the phone or computer. I have had past problems with vertigo and tired and dry eyes and I truly believe these have made a difference! Highly recommend!
Love them
I notice a lot less eye strain, reduced headaches and increased focus when using screens while wearing the Nate Daylight glasses. Very comfortable to wear, would highly recommend!
It is truly relaxing to wear these while working online during the day. I love the frames!
