Yes, online eye exams exist, and several companies offer them for between $15 and $50, with a few options that are free. These tests let you check your vision from home using a smartphone, computer, or tablet, and a licensed eye doctor reviews your results to issue or renew a prescription. But they come with significant limitations: they’re designed for a narrow group of people and can only measure how sharp your vision is, not whether your eyes are healthy.
How Online Eye Exams Work
Most online vision tests follow a similar process. You position yourself a set distance from your screen (some services have you hold a credit card or driver’s license up to calibrate the display size), then read letters or symbols that get progressively smaller. The test takes 5 to 15 minutes depending on the platform. Your responses are sent to a board-certified ophthalmologist or optometrist licensed in your state, who reviews the results and either issues a new prescription or confirms your existing one.
In 2023, the FDA cleared the first online visual acuity test, made by the telehealth company Visibly, for adults ages 22 to 40. The FDA was explicit that the test is not a substitute for screening or diagnosis of eye diseases. That distinction matters: these tests measure refractive error (whether you’re nearsighted, farsighted, or have astigmatism) but nothing else.
Who Qualifies for an Online Exam
The American Academy of Ophthalmology says online vision testing should be limited to healthy adults ages 18 to 39 who already have a mild or moderate eyeglass prescription and no symptoms of eye disease. If you have a high-power or irregular prescription, these tests aren’t accurate enough to be useful.
You should skip online testing if any of the following apply to you:
- Diabetes or high blood pressure, since both conditions can damage blood vessels inside the eye
- A family history of glaucoma
- Any current eye symptoms like flashes, floaters, pain, or sudden vision changes
- No recent in-person eye exam, meaning you don’t have a baseline for comparison
- Age 40 or older, when the risk of age-related eye conditions rises significantly
What Online Tests Cannot Detect
An in-person eye exam involves far more than reading a letter chart. Your eye doctor checks peripheral vision and depth perception, which are critical for detecting glaucoma. They inspect the lens for cataracts, measure internal eye pressure, and evaluate the muscles that control eye alignment and focusing, which can reveal neurological disorders.
Perhaps the most important part of an in-office exam is the retinal evaluation. By looking at the back of your eye, a doctor can spot macular degeneration, retinal tears or detachments, and damage to the optic nerve. The blood vessels in your retina also provide a window into your cardiovascular health: signs of high blood pressure, high cholesterol, and even early diabetes can show up there before you notice symptoms elsewhere. None of this is possible through a screen.
Major Providers and Pricing
Several companies currently offer online vision tests, all reviewed by a licensed eye care professional:
- 1-800 Contacts: $20, results in a few business hours, reviewed by a licensed ophthalmologist in your state
- LensDirect: $15, about 5 minutes, results within 24 hours
- Warby Parker: $15 (sometimes discounted to $5), about 10 minutes, results within 48 hours
- Lens.com: $30, about 10 minutes, results within 24 hours
- WebEyeCare: $50 for contacts, $40 for glasses, results in 1 to 2 business days
- AC Lens: Free, about 15 minutes, results within 24 hours
- Discount Contact Lenses: Free with a purchase, results within 24 hours
These prices reflect early 2024 data and may shift. Most services are designed for prescription renewals rather than first-time exams.
Insurance Coverage
Most vision insurance plans don’t cover online eye exams, but there are exceptions. UnitedHealthcare Vision offers its eligible members access to an online exam through 1-800 Contacts at no additional cost. That benefit isn’t available on all plans or in all states. For most people, online exams are an out-of-pocket expense, though the $15 to $50 price range is often cheaper than an in-office copay for those without vision insurance.
State Restrictions
Not every state allows online-only vision testing. South Carolina’s Supreme Court unanimously upheld a state law banning online-only vision tests for prescription renewals, ruling that the prohibition is constitutional. That law, in effect since 2016, requires patients to undergo in-person exams. Other states have varying telehealth regulations that may limit which services are available where you live. Before signing up for an online exam, check whether the provider operates in your state, as most will tell you upfront during registration.
How Long Your Prescription Lasts
A prescription from an online exam carries the same legal weight as one from an in-person visit. In most states, eyeglass prescriptions are valid for at least two years. California law, for example, sets the range at two to four years unless a doctor documents a reason for a shorter window, such as a condition likely to change your vision. Contact lens prescriptions typically expire after one year under federal law. Whether your prescription came from an online test or a physical office, the expiration rules are the same.
When an Online Exam Makes Sense
Online vision tests fill a specific niche: you’re a healthy adult under 40, you already know your approximate prescription, and you just need a renewal to order glasses or contacts. For that narrow use case, they’re fast, affordable, and legitimate. They work best as a convenience tool between full eye exams, not as a replacement for them. The American Academy of Ophthalmology recommends a baseline comprehensive eye exam by age 40 at the latest, with more frequent visits if you have risk factors. An online test that tells you “your vision is 20/20” can’t tell you whether something silent is developing behind the scenes.
