Medical Forum / General / Vision / September 2006New glasses issue
I don't know very much about glasses other than what I have read online. I just got my new lenses and I am not sure if the problem I am having is me or the glasses. With my old frames, I never had this issue. I am near sighted and can now see objects further away really clear, which is great. The issue is that I am now getting headaches looking at objects that are up close. I have always removed my glasses to read, but now I can't enjoy meals with my family because looking at the food on my plate gives me a headache with my glasses but without my glasses, I can't see my family's faces. Could it be because my prescription is stronger now? I don't have this problem when I wear my contacts. What could be causing this and how can I fix it? Is my optometrist at fault or the people who made my glasses? Also, I am using polycarbonate lenses which are supposed to be anti-reflective but I now feel like I have eyes on the back of my head because I can see any light source from behind me reflected onto my lenses, particularly towards the corners of my lens. This has been incredibly frustrating. Dear Friend, Please post your new prescription. It could be there is an error in the prescription. If you have the older prescription -- perhaps you could post that. Sometimes the astigmatic component is excessive, and will cause distortion in your perpherial field. You might prefer a "spherical" prescription -- if that meets your the legal visual requirements needs. Best, Otis > I don't know very much about glasses other than what I have read > online.

You may need progressive lenses, which have a different strength for distance (top) and reading (bottom), with a progressive transition area in the middle. This is likely if your age is 40 or more. Please list your Rx and your age. Also, specify the brand of the lens. Polycarb is the worst possible lens material you can purchase from a optical quality perspective. It can be particularly bad in a mid to high power aspherical design anywhere but dead center (when you are reading or looking at people slightly off-center, you are probably not using the center of the lens). You might want to ask for a remake of the lens using 1.60 material. Even 1.67 would be better from a high quality lens manufacturer. It is not unusual for someone to get a lens power that is a bit too strong, so mention your problems to whomever did the eye exam. The reflections are probably caused by polished edges. Do not get polished edges. >I don't know very much about glasses other than what I have read >online.

If you don't have the same problem with contacts, you can (probably) rule out the extra work your eye muscles have to do when focusing on near objects with far vision corrected. One of the big differences between glasses and contact lenses for people with myopia (like you and me) is that glasses make objects look smaller than they really are. If you have -5.00D correction, for example, objects look about 10% smaller through glasses than contacts (or with no correction at all). I've only recently started wearing contacts myself, and find that this de-magnification is pretty irritating when I have glasses on instead of contacts. My correction is -3.75D, so the difference in apparent size is somewhere around 7% for me. >Also, I am using polycarbonate lenses which are supposed to be >anti-reflective but I now feel like I have eyes on the back of my head >because I can see any light source from behind me reflected onto my >lenses, particularly towards the corners of my lens. > >This has been incredibly frustrating. I find the reflections pretty annoying as well. Overall, I think it's probably just the price you pay for having worn contacts. All the annoyances of glasses are magnified in perception. Having a stronger prescription can certainly magnify some of these effects. Every time I've gotten a new (stronger) prescription, it took me time to get used to the new size distortion magnitude. If you have contacts, then you're probably not wearing the glasses very often, which will certainly make it more difficult to adapt to the new prescription. If it really bothers you, then leave the contacts out entirely for a week, perhaps, and wear only glasses. It may or may not help in the end, since you're likely to experience at least some of the symptoms each time you move from contacts to glasses. At least, that's the case for me.

It's possible, if not likely, to have these problems even if the Rx and lens design/fabrication is spot on. Although errors are possible, the fault here is probably a lack of communication- your eye care provider(s) should have anticipated these problems and should have explained to you why they may occur. >Also, I am using polycarbonate lenses which are supposed to be >anti-reflective but I now feel like I have eyes on the back of my head >because I can see any light source from behind me reflected onto my >lenses, particularly towards the corners of my lens. This doesn't happen with your previous pair? It's normal to see some reflection on the lens, even when coated, if the light from behind you is very bright. Mention this to your ECP when see them in regards to the vision problems.
