An online eye exam is an automated and interactive vision test that claims to measure visual acuity. It may seem like a convenient way to evaluate your vision or get an eyeglass or contact lens prescription from your computer, tablet, or smartphone. However, these tests are performed by a computer program, not a professional eye care practitioner, and they cannot and should not replace a comprehensive, in-person eye exam.

What Do Online Eye Tests Evaluate?

Online eye tests are more of a vision test than a true eye exam. They're designed as an attempt to measure your visual acuity and refractive error, and in some cases contrast sensitivity and color blindness. They do not evaluate the health of your eyes.

The accuracy of prescriptions provided by online vision tests is questionable. Providing the correct optical prescription requires direct communication and experienced analysis from an eye doctor — professional skills that cannot be accurately replicated through an online program.

The Importance of a Comprehensive Eye Exam

Optometrists undergo years of study and specialized training. Comprehensive eye exams enable your eye doctor to detect signs of diseases that may affect your entire body, including hypertension, high cholesterol, diabetes, strokes, Sjogren's syndrome, and neurological diseases such as multiple sclerosis.

Is a Virtual Eye Test Cost-Saving?

Some people believe an online eye test saves time and money. However, these virtual tests offer only a fraction of the services you'd receive from a thorough ocular exam. Anything less can put your eyes and vision at serious risk.
