i have an eye appointment at walmart tomorrow and i haven't had an eye exam in three years yea i know thats pretty bad i was just wondering how the did the exam as in do they have a machine like lens crafters or if i have to read the letters on the chart because if it's the chart i'll probably be guessing the letters because my eye is way off from my last prescription
The eye doctor that has an office at walmart has all the same equipment as any other eye doctor. Do not guess letters. If you have to guess, let the doctor know that you cant make them out and are going to give your best guess. Don't want to skew your results. There should also be a part of the exam, looking at the chart, the doctor will ask you the smallest row that you can see clearly. Just be honest so you get the right prescription.
