The Dangers of Online Eye Tests
Online eye tests are just that, simple vision tests like you might have received in grade school. All it can do is measure your basic vision to determine nearsightedness, farsightedness, or astigmatism to determine an eyeglass prescription for you.
However, since this is a test that is essentially a self test, as opposed to one carried out by a trained professional, its basic accuracy is very questionable. What many do not realize is that when an optometrist performs an eye exam to determine your prescription, some measure of judgement on their part is required, based on factors such as your age, profession, or hobbies. These factors can lead them to recommend specific lens types better suited to your needs.
Online vision tests are incapable of this.
In fact, studies show that almost half of prescription glasses ordered online have incorrect prescriptions or fail to meet safety standards.
Because of this the American Optometry Association (AOA) has made statements condemning online eye tests.
Furthermore, proper eye exams do far more than simply testing your vision. If you only use these basic vision tests to judge your eye health, you can put your eyes, and your vision, at risk.
