Hi all, I had my routine eye exam today. I haven't tested my eyes for the past 5 or 6 years. I don't wear any eyeglasses or contact lenses. I am very new to this eyeglasses terminology and other stuff. I had a feeling of some pressure above my right eye and went to optometrist to check on that. I don't have any pain. Just feel like a pressure above my eye. He tested and said, there are no issues inside my eyes and while testing to read the alphabets on the board, I feel little difficult to read few letters and he prescribed an eyeglass for me. He said the eyeglass may help to relieve my pressure like feeling and try wearing for 2 weeks. Then told me to check with my PCP after that if this problem continues. He said,it might be due to sinus infection. So I have to check with PCP. The prescription says some values and I don't really understand what are those. I went to the nearby optic store and they didn't accept my insurance for the eyeglass. So,I came back. I am checking for some stores which accept the insurance. The prescription says,the sphere value for RT is -0.25 and LT is Plano. The cylinder for RT is -0.75 and LT is -0.25. I don't know what to check while buying the eyeglass. Or the optician will help us to get the required eyeglass with all those mentioned values. Can somebody help me to understand the things to look when buying an eyeglass. What is the chepaer store to buy an eyeglass? Any online sites available or in store? Thanks for reading this.
