Your OPTOMETRIST typically does a refraction with a manual machine, leaving room for human error. With digital eye tests, your previous glasses are scanned and input into the computer. Your eye is scanned, giving an objective reading of your eyes’ refractive error, and the computer program measures your subjective responses versus your current glasses and eye scan data.
The output is reviewed by an OPHTHALMOLOGIST, and an extremely accurate prescription is produced. There is no need to dilate your eyes for this process, and you can compare your new prescription to your old prescription Immediately.
