Do you have tired and sore eyes just daily or after long periods of reading/ working on a computer? If your eye doctors are unable to diagnosis a vision issue, you may benefit from some of the "migraine glasses" that help block out the blue light. I find these glasses helpful, especially if I need to be on my laptop or if I am going to be subjected to certain kinds of lighting. Have you considered that something along these lines may be what is causing your eyes to feel tired and sore? Best wishes - Amanda (team member)
