I have had a lot of eye/vision issues with my diabetes. Since July 2009, my eyeglass prescription has changed 4 times. I have retionopathy and cataracts. I have had a diabetic eye exam done in September 2009. My eye doctors have both told me that blood sugar readings need to be around 120 consistantly before any vision issues can be resolved. I have also been told that your vision changes with your blood sugar readings. If you see an eye doctor, and you need glasses, your eyeglass prescription will be based upon what your blood sugar is on the day of your exam. If your blood sugar is 200 on the day of your exam, and you get classes and then a month later if your blood sugar drops to 150 or lower, your prescription more than likely will be different. I go to Wal-Mart to get my glasses. They will change your prescription for free if your prescription changes within 60 days. This has saved me hundreds of dollars. Check with your vision care specialist to see if they have a such a quarantee. Please get your eyes checked. This is very important. Most eye doctors know that people with diabetes may require more treatment than the average person and are willing to help. Just be honest and let them know what your blood sugar readings really are. Most will not give you a big lecture. Be patient and take good care of your eyes.
