Hello, I bought a new pair of glasses a little over a month ago and at first they seemed hard to adjust with some eye tension and some headaches but eventually went away but now I’m noticing that my right eye is blurry when looking at words numbers like on a digital clock from a distance of about 6 feet and greater but up close I don’t notice any difference? I went back to the eye doctor and they put me on the eye machine to look at the chart and when they adjusted the focus i could see perfect out of my right eye and was told the prescription was the same as the glasses? I put my glasses back on and the blurriness is still there as before? what could this be?
