I was satisfied with everything but the clinical test to measure my degrees. I have strong astigmatism and developing myopia. The test to determine my eyeglasses degrees typically takes no less than 15 minutes.This provider only made me read the line on the screen 3 times, taking less than 5 minutes.My new eyeglasses aren't optimal. I wouldn't recommend this doctor.
