Dr. Kim provided prescription that was wrong; therefore, for 1 year my eyes glasses was not correct and may have caused my eyes to get worse. I did complain and was told 'it requires time to get use to' and it's the cheap 'lens' and I should have upgraded to better lens. Because I got my prescription from Dr. Kim and the glasses and lens from Target, I didn't know if it was the glasses or the prescription until I got checked recently and found the error. My 2015 glasses and 2017 was near the same, while my 2016, from dr. Kim was wrong and complete opposite (right to left eye). Dr. Kim even calibrated my original glasses wrong, insisting it was a '3 degree' but when I checked with target, it was only 1 degree for my right eye. How can 2 mistakes occur in 2 sitting? My eyes may have gotten worse because of Dr. Kim's error and I'm sad as it's not worth going to court over this. I just want people to know and be careful. Nothing can be done now as it's been over a year so Dr. Kim won't even replace my lens... Yeah, I should have complained more often, but now I know doctors are not always right in their diagnosis and you should trust yourself.
