Dr. Kevin Tyber has became very rude in the past couple of years. He disrespect his patients. He pushes patients to buy the frames/glasses from his own shop. If the glasses are bought else were he would not even look at them. He gave me incorrect prescription. When I got my glasses I was not able to see things properly. Everything was blur. Dr. Tyber refused to see me again without paying him again. In the second visit he found a mistake in his prescription but again he blamed it on the place from where I bought my glasses. (note that I got my glasses from one of the top Eye glasses store chain in North America) Save yourself from humiliations and not see this doctor.
