These browser activities are for practice only when recommended by your eye-care professional.

Scanning

Match the pairs in this classic memory challenge to boost sustained attention and binocular coordination.

Best for building tracking accuracy across the visual field.

Tracking

Follow and click the numbered balls in sequence as they glide around the screen.

Supports smooth pursuit control and timing.

Saccades

React to balls that appear one at a time in different locations to sharpen quick eye movements.

Ideal for practicing rapid refixations and visual scanning.

Fusion Quest

Align complementary red and green portal pieces to practice using information from both eyes together.

Adaptive binocular alignment with measurable session feedback.

Binocular Invaders

Use complementary red and green/blue information together to aim at moving target cores.

Short, adjustable action practice with visibility checks and no lives.

What is diplopia (double vision)?

Diplopia means seeing two images of a single object. The images can be side by side, one above the other, or diagonally separated. Read the full explanation →

Dichoptic therapy FAQ

What is dichoptic therapy?

Dichoptic activities present different visual elements to each eye at the same time. Whether an exercise is appropriate depends on the cause of double vision and should be discussed with an eye-care professional.

Do I need special equipment?

Yes. Wear red/green or red/blue anaglyph glasses so each eye sees its target. Pair the glasses with balanced room lighting and sit 50–70 cm from the screen for consistent fixation.

When can vision rehabilitation help?

Double vision has many possible causes. An eye-care professional should assess it first; rehabilitation exercises may be considered as part of care for some diagnoses.

Are these exercises a substitute for medical evaluation?

No. The exercises described on this site are not a substitute for medical evaluation and should always be part of a plan led by your eye doctor and vision rehabilitation specialist.

Do eye exercises really help with double vision?

Exercise-based care is used for some specific diagnoses, but evidence and suitability vary. These activities are not validated for every cause of double vision; ask your eye-care professional whether they fit your diagnosis and care plan.

How often should I practice?

There is no single schedule that is right for everyone. Follow the plan from the clinician who knows your diagnosis, and ask before changing the length or intensity of practice.

How long does it usually take to see improvement?

There is no general timeline, and this site cannot predict whether these activities will change symptoms. Discuss changes with your clinician and stop if symptoms are new or worsening.

Therapy tips

Blend these strategies into your daily practice routine:

  • Only use activities and settings that your eye-care professional has recommended for you.
  • If your clinician asks you to track practice, note the activity and how you felt during and after it.
  • Pause or stop if an activity causes significant discomfort or makes symptoms worse, and contact your clinician for guidance.
  • Use the screen position and viewing distance specified in your care plan.
  • Safety note: If double vision is sudden, new, or rapidly worsening, or comes with severe headache, eye pain, weakness, confusion, or slurred speech, seek urgent medical care.
