II. How We Chose the Best Online Eye Exams

In curating our list of the best online eye exams, we looked for providers that are trustworthy, convenient, and place patient safety first.

Services available

There are two main types of online eye care available: basic vision screenings, to help determine if a comprehensive eye exam is needed; and eye exams, to confirm glasses or contact lens prescriptions. In order to make recommendations for all types of patients, we included both types of services on our list.


One of the key selling points of an online eye exam is convenience. We looked for services that require only minimal set-up, as well as tools that most people have handy, including a computer or smartphone with a microphone. We also prioritized services that have a quick turnaround time for results, so users can proactively take the next steps.

Optometrist review

For online eye exams for prescription renewals, it’s key that a board-certified optometrist reviews the results to confirm that you have the right prescription for your contact lenses or glasses. All eye exam services on our list include an optometrist review as standard practice.

III. The Best Online Eye Exams



Launched in 1995, 1-800-Contacts is an e-commerce pioneer, making it faster and easier than ever for customers to purchase their contact lenses. They have recently made the process even more convenient by offering their Express Exam, which lets customers renew their prescription online without having to visit their eye doctor.

The Express Exam process is simple. Customers answer basic questions about their age, location, and eye health history to confirm their eligibility for the online exam. Eligible customers upload pictures of their eyes so the doctor can check for redness or irritation, followed by a simple vision test to check if the patient can see clearly in their current contacts. Customers must have a smartphone or computer with a camera and microphone to complete the vision test.

A board-certified ophthalmologist will review the results within 24 hours, and determine if the prescription is valid, or if adjustments are necessary.

Many people remember having their vision tested by a school nurse when they were elementary students. While not a comprehensive eye exam, these tests help identify possible vision problems that need further assessment and remediation.

Thanks to computer and smartphone technology, those types of vision assessments are now available to everyone from the comfort of their own home. Essilor, a leading international ophthalmic optics company, is one such provider of these online vision tests.

With Essilor, the process is fast and simple. Using only a computer, patients complete basic tests to assess different aspects of their vision, including  visual acuity, astigmatism, light sensitivity, near vision, color vision, and age-related macular degeneration (AMD).

Based on their answers, users will receive results and recommendations for further actions. While not a replacement for a comprehensive eye exam, this vision test can help patients identify problem areas to discuss with their eye doctor.

IV. What You Need to Know About Online Eye Exams

An online eye exam or vision screening is not a replacement for an in-person, comprehensive eye health exam. The frequency of in-person eye exams depends on many factors, including age, overall health, medical history, and whether you wear corrective lenses or have other vision problems. Generally speaking, it’s recommended that adults have an in-person eye exam at least every five years.

Online eye exams can be convenient tools for individuals who need to renew a prescription, while vision screenings can help individuals preliminary identify issues. However, these types of services do not test all of the aspects of eye health, including eye muscles, glaucoma screenings, retinal exams, visual field, and more.

“Literature shows that with the improvement of imaging and video conferencing technology along with the need for social distancing, the use of tele-optometry is becoming more useful and acceptable with patients,” says Susy Salvo-Wendt, telehealth specialist

For patients using an online eye exam as a way to confirm a contact or eyeglass lens prescription, different services may limit eligibility based on age, medical history, and whether the individual has other vision problems.

Additionally, consumers may also run into state restrictions when it comes to getting an online eye exam. Regulations for online vision care have been a subject of ongoing debate for several years, resulting in a patchwork of access to these services.

V. Latest News

As with many areas of medicine and healthcare, much of the current news about online optometry and eye exams reflects how the COVID-19 pandemic is affecting these services.
