Are Online Eye Tests Reliable and When Are They Useful?

Today, you can have your eyes checked without actually seeing your eye doctor using online vision tests. Many eye clinics offer these tests that you can accomplish via your smartphone. They claim to determine how sharp your vision is, if you have astigmatism, or experiencing eye sensitivity.  

Discover if online eye tests are any good and when they are useful from a local eye exam doctor. 

Are Online Eye Tests as Good as Visiting Your Eye Doctor?

Typically, an online eye test only checks your visual acuity and gives an estimate of your refractive error. Sometimes, it includes contrast sensitivity and color blindness. However, this kind of test can’t determine if you have conditions like glaucoma, cataracts, or macular degeneration. 

Keep in mind that routine eye exams with your eye doctor are still irreplaceable. Get your eyes checked as frequently as advised by your eye specialist. Regular comprehensive eye exams can help with the early detection and treatment of different eye conditions, especially those that don’t show symptoms until their later stages. 

When Are They Helpful?

When you’re away, and you break or lose your glasses or contact lenses, that’s when online eye tests are most useful. Sometimes, an online vision test can help keep track of your eyesight and refractive error between routine eye exams. Still, it helps to know that the results of some online eye tests have been validated with limited studies because it’s still a new and developing technology. More studies are required to ensure the accuracy of prescriptions generated by online vision tests.
