Eye pain after wearing new gles?

It's hard to determine exactly what is going on, without seeing your eyegles. However, it sounds to me that your getting an unwanted prismatic effect from the gles (eye pulling or feeling cross eyed). In optics, your eyes will naturally pull towards the base of the lens. First, I would have your optometrist or your optician check your gles to see if they were ground properly. We take centering measurements to make sure your eyes are aligned with the optical center of the lenses. The optical center of a lens is the ONLY spot where light does not bend and is not dispursed. If the lenses are not squared up and inline with your eyes, you can/could feel an eye pulling effect. The higher your rx is the worse the feeling can be. Secondly, I do not feel that it is a lens material problem. Lens technology now a days is far superior than even 10 years ago. High Index lenses are much thinner and flatter than polycarbonate, and will give you the best vision possible. Most lenses, today, are made aspherically (flatter) vs. spherically (curved). Thirdly, notice your old axis was at 123 and the new axis is at 132. This is the astigmatism placement in 180 degree range. It is 9 degree's different. Was your optometrist trying to give you your old rx back? If so, it looks like the axis numbers were reversed, probably by accident. Did he/she mean to write 132 or was it meant to be written as 123? Sometimes this number does change and that can be normal. If/when it does change, the difference in amount can cause a feeling of nausea and such. And your eyes may take a few days to get adjusted. In your case, its only 9 degree's different which is not much for your amount of astigmatism. So I don't think this would be the case either. But I would verify with your doctor that the number was written correctly. IMHO, I don't think the gles were made properly, and this would be my first step. If they check them and say that they were made properly, you have the right to take them elsewhere and have them verified for a 2nd opinion. Any optician will be willing to do this for you at no charge. Good luck! Feel free to email me if you have any more questions or concerns!
