My 17 year old daughter's vision has gotten increasingly worse over the past 6 years since she started wearing glasses. At first the opthamologist told us that her vision was correctable, and she would not need to wear glasses in 2 years. Well its been 6 years, and her eyesight is getting worse. We are currently living in Korea, and this past summer we got my daughter a new perscription of eyeglasses while visiting the U.S. the Opthamologist said that she had astigmatism. She has never had this before, we knew she complained of needing new glasses, but we never knew her vision had changed this drastically. So we bought my daughter a new pair of glasses, with the correct perscription. About 2 weeks later after returning home, my daughter complained of blurry eyes. We got her eyes checked and strangely her eyesight had gotten worse. This has been going on for far too long, and her eyesight is getting worse. Her astigmatism is more pronounced, and her perscription becomes stronger with each eye visit, what could possibly be the problem?
