Answers to Common Questions

Q. How often should I have my eyes checked?

A. This depends on your age and medical conditions. Generally, if you are under the age of 18 or over the age of 65, you should have your eyes checked on a yearly basis. Between the ages of 19 and 64, every two years should be enough. If you have medical conditions, such as diabetes or a family history of glaucoma or macular degeneration, more frequent checks may be necessary.


Q. What is a digital eye test and how is it different from what my OPTOMETRIST does?

A. 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 eye for this process, and you can compare your new prescription to your old prescription immediately.


Q. How do you test my eye pressure without a puff of air?

A. We use the latest digital technology called transdermal tonometry, which is done on the outside of the closed lid. The air puff is older technology which is considered inaccurate due to the blink response associated with the discomfort it produces. In clinicals, transdermal tonometry has proven to be as accurate as the Goldmann tonometer which is the industry standard.
