Vision Therapy Online: Telehealth, Apps, VR and the Studies

Updated 2026-10-25

Written by the Optics Trainer team from published research, with every source linked below.

Vision therapy online means doing some or all of a vision therapy program through a screen. That can be a video visit with a therapist, a computer program your clinic prescribes and checks over the internet, an app, or a VR headset. This guide explains each model, what studies of remote and home digital therapy found, and what the American Optometric Association (AOA) says about telehealth. For home versus office care in general, see our guide to home vision therapy. This page is about the online and remote delivery model.

What is online vision therapy? Four models

"Online vision therapy" and "virtual vision therapy" are used for quite different things. Asking which model a program uses helps you compare them:

Clinician-led telehealth sessions: a therapist guides exercises over live video, usually after an in-person exam.
Clinic-prescribed home computer programs: the clinic sets up a program such as HTS2, the patient trains at home, and the clinician reviews results online and changes settings.
App-based training: phone, tablet or web programs. Some are prescribed and monitored by a clinic. Others are sold directly to the public with no clinician involved.
Virtual reality: headset programs, some prescription-only, that show each eye its own image.

Clinic-prescribed home computer programs, such as HTS

The Home Therapy System (HTS) is the program used in the CITT and PEDIG convergence insufficiency (CI) trials. As of October 2026, the company's HTS2 page describes a web-based home eye exercise system developed by Dr. Jeffrey Cooper and Rodney K. Bortel. It runs on most iPads, Android tablets, Chromebooks and Windows and Mac computers. From their own computer, clinicians can review each patient's results and practice history, adjust the program and message the patient. The program can also raise the difficulty on its own. For families, training happens at home while the clinician can still see the date, length and score of every session. The page also states that HTS2 does not treat or diagnose any specific medical condition or disease.

Visitrain, a clinic-monitored phone app, was tested in a 2026 study described below.

Online vision therapy for convergence insufficiency: what studies found

Most studies of remote and home digital therapy are in CI. The 2008 Convergence Insufficiency Treatment Trial (CITT) randomized 221 children aged 9 to 17 to four treatments. One group used the HTS program at home for 15 minutes a day, plus pencil push-ups. After 12 weeks, 33% of that group were successful or improved, compared with 73% for weekly office therapy with home practice and 35% for placebo. A 2016 trial of 204 children tested home therapy alone and found 23% success with home computer therapy, 22% with push-ups and 16% with placebo. A 2020 Cochrane review rated the evidence high certainty that office therapy with home practice beat home computer therapy in children. Our guide to convergence insufficiency games covers these trials in detail.

Newer studies tested digital home programs with remote monitoring:

Virtual vision therapy and telehealth sessions

In the 2026 Visitrain study, patients used the app on their own phones at home for 15 minutes a day, and an optometrist monitored their progress remotely and adjusted the settings. The office group followed a CITT-style program. Office therapy was ahead on near point of convergence and eye-teaming range at one month, and the groups did not differ significantly at three months. App compliance was 95%. The authors called for controlled trials, and several of them work for the company that makes the app.

We did not find a randomized trial of live video vision therapy sessions. Published data on remote care include surveys from the COVID-19 period. In a 2020 survey of UK and Irish orthoptic departments, with a 79% response rate, 94% reported a rise in tele-consultations by phone and video. Most departments said the remote visits were going well. The main problems they reported were IT, ethics and confidentiality. By summer 2020, 92% still used teleconsultations, with triage to decide who needed to come in. In a 2026 report from one children's eye service, 91.2% of offered home vision tests during remote follow-up gave usable results.

Vision therapy games online and virtual reality vision therapy

Game-based and VR programs have been tested mostly for intermittent exotropia (an outward drift that comes and goes) and lazy eye:

A 2024 prospective study, in which children chose whether to train, followed 55 children after surgery for intermittent exotropia. The 29 who did an online dichoptic game for 3 months had better distance depth perception and less distance drift than the 26 who did not. Software records showed 28 of 29 finished all 180 sessions. The authors called for randomized trials.
A 2026 randomized trial of 177 children aged 6 to 18 found a home VR program improved distance control of intermittent exotropia at 12 weeks compared with observation, by 0.33 points between groups, which the authors called modest. Long-term follow-up was still under way.
Luminopia is a prescription VR treatment for amblyopia used at home. The FDA granted it De Novo authorization in 2021 for ages 4 to 7, and in April 2025 cleared it for ages 4 to under 13. Our guide to VR lazy eye treatment covers it.
For CI, a 2025 review found only three VR studies and said the evidence was not enough to draw firm conclusions.

Online vision therapy for adults

Fewer studies included adults. The 2020 Cochrane review called the adult CI evidence "less clear." In the 2020 CINAPS trial of 50 adults with CI, home practice was entirely computer-based. The Visitrain study included patients up to age 46. In a 2024 study of adults with double vision, with an average age of about 62, one of the home vergence programs sent results to a remote server so the clinician could follow daily performance. Two of the authors helped found the company that makes that program. See our guide to eye exercises for double vision.

Telehealth rules: what the AOA says

The AOA's 2025 position statement on telemedicine says in-person care by an optometrist is the criterion standard for a comprehensive eye exam. It says the standard of care must be the same whether care is given in person or remotely. Remote patient monitoring may be appropriate, for example, to confirm that a treatment is working as expected. Unless the law allows otherwise, an optometrist giving telemedicine must be licensed in the state where the patient is. Optometrists must refer for in-person care when it is clinically appropriate and have a plan for local urgent and emergency care. We did not find a telehealth statement on vision therapy from COVD or the AAO.

Questions to ask any online program:

Who diagnosed me, and in what kind of exam?
Is my clinician licensed where I live?
Who reviews my results, how often, and what happens if I fall behind?
When do I come in person for a recheck?
If headaches, eye pain or double vision appear during an exercise, should I stop and call?

Where Optics Trainer fits

Optics Trainer is an online, non-prescription training app. It runs in web browsers and on iPhone, iPad, Android and Meta Quest. It includes eye teaming games with convergence and divergence levels, binocular games where each eye gets its own target (red-blue glasses on phone, tablet and computer, built in on Quest), and sports and performance games for reaction time, tracking and peripheral awareness. Its Drills tab has watch-and-follow saccade, pursuit, peripheral awareness and multiple-object tracking drills with no score, at slow, medium or fast speeds for 1, 2 or 3 minutes.

Optics Trainer is not telehealth, and no clinician monitors it. It was not part of the studies described above, it is not a treatment or diagnosis, it is not FDA cleared, and it does not measure anything. Optics Tracker, on our clinic site, is our measurement product for eye care professionals. Optics Trainer is not a substitute for professional diagnosis or prescribed care. Consult your eye care professional for guidance about your specific condition.

As of October 2026, mobile and web training is $14.99 a month or $149.99 a year. The phone and tablet apps start with a 7-day free trial, and a free web account includes 3 plays a day. VR training on Meta Quest is $19.99 a month or $199 a year after a 7-day free trial.

Frequently asked questions

Does online vision therapy work?

It depends on the model and the condition. In children with convergence insufficiency, a home computer program plus pencil push-ups did no better than placebo on symptoms in CITT, and office therapy with home practice had the highest success. Newer apps with remote monitoring have been tested in studies of 25 and 33 people.

Is virtual vision therapy as good as in-office therapy?

We did not find a randomized trial comparing live video therapy with office therapy. In a 2026 retrospective study of 33 people with CI, an app with remote monitoring was behind office therapy at one month, with no significant difference at three months. The authors called for controlled trials.

Can I do online vision therapy for convergence insufficiency?

Clinics do prescribe home computer programs for CI, often with online monitoring. In trials of children, office therapy with home practice had the highest success rates. Ask your eye care professional whether a remote program fits your diagnosis and how it will be checked.

Are there vision therapy games online?

Yes. Some are prescribed and monitored by clinics, and others are sold to the public. A 2024 study of an online dichoptic game after surgery for intermittent exotropia reported better distance depth perception in the group that trained. Children chose which group to join, so the study was not randomized.

Is online vision therapy good for adults?

There are fewer adult studies. A 2020 Cochrane review called adult CI evidence less clear. Some studies of computer-based home practice included adults, such as the CINAPS trial of 50 adults and a 2026 app study of people up to age 46.

Do I need an eye exam before online vision therapy?

The AOA says in-person care is the criterion standard for a comprehensive eye exam. Symptoms like blur, double vision and headaches have many causes, so a full exam with a binocular vision evaluation should come first. Sudden double vision is different: MedlinePlus says to seek emergency care, and with weakness, trouble speaking or a severe headache, call 911.

What is virtual reality vision therapy?

It uses a headset to show each eye its own image. A prescription VR treatment, Luminopia, is FDA cleared for certain children with amblyopia. A 2026 randomized trial found a home VR program improved intermittent exotropia control at 12 weeks, by an amount the authors called modest.
