Frequently Asked Questions
About Vision Therapy

A consultation at Caring Vision Therapy costs between ₹1,000 and ₹2,000. Online consultations sit at the lower end of that range (₹1,000 to ₹1,500); in-clinic assessments in Chennai and Hyderabad sit at the higher end (₹1,500 to ₹2,000) because they include hands-on diagnostic testing, and complex neuro-visual cases such as post-concussion or post-stroke assessment are ₹2,000. The exact figure within each band depends on the condition being assessed, and you are told it when you book. The therapy programme is quoted separately, in writing, after your evaluation - because the number of sessions a condition needs varies too much to price in advance honestly. For context, a complete vision therapy programme in the United States typically costs between $2,000 and $6,000; in India, equivalent care from internationally credentialled practitioners is available at a fraction of that. See our vision therapy cost guide for the full fee table, and our Payments page for accepted payment methods.

Vision therapy is a structured, evidence-based program that improves how the eyes and brain work together. It targets eye coordination, focusing, tracking, and visual processing skills.

Children with learning-related vision challenges, adults experiencing eye strain or binocular vision disorders, and patients recovering from neurological conditions may benefit.

Yes. Vision therapy is supported by clinical research and follows globally accepted neuro-optometric rehabilitation standards when prescribed for appropriate conditions.

How long vision therapy takes depends on the condition being treated, the severity, the patient's age, and how consistently the home exercise programme is followed. Here is a realistic breakdown by condition:

• Convergence insufficiency: 12 to 24 weekly sessions for most cases. The CITT clinical trial established 16 to 24 weeks of supervised office-based vision therapy as the gold standard. Mild cases may show measurable improvement in 8 to 12 weeks.
• Amblyopia (lazy eye): 6 to 18 months depending on severity, the degree of suppression, and the patient's age. Adult amblyopia takes longer than childhood cases but still responds to structured therapy. Early results are often visible within 2 to 3 months.
• Strabismus (squint): 3 to 12 months for intermittent forms treated non-surgically. Post-surgical rehabilitation after squint surgery typically runs 12 to 24 additional weeks to build functional binocular vision.
• Visual processing disorders: 16 to 24 weeks for most school-age children. Improvements in reading fluency, copying speed, and visual memory are often reported by parents and teachers within the first 8 to 10 weeks.
• Post-concussion / TBI visual rehabilitation: 6 to 24 months depending on injury severity and the number of visual systems affected. Progress is slower but still clinically meaningful for patients years after their injury.
• Post-stroke vision rehabilitation: Highly variable - 6 months to several years for hemianopia and visual neglect. Prism therapy and scanning training can produce functional improvements even in chronic cases.

Most patients complete 24 to 48 total sessions (weekly or bi-weekly) across the full programme. Sessions are typically 45 to 60 minutes in clinic, plus 15 to 20 minutes of prescribed home exercises daily. At Caring Vision Therapy, we give you a written timeline and milestone targets at your initial evaluation so you know what to expect at each stage.

Children as young as 3 or 4 years old can begin certain types of vision therapy, particularly for conditions like amblyopia and strabismus where early treatment gives the best outcomes. The program is always designed around the child's age, attention span, and ability to participate. Older children and teenagers respond just as well and typically progress faster because they can follow instructions more easily.

Yes, in many cases. Vision therapy is highly effective for certain types of squint, particularly intermittent exotropia, accommodative esotropia, and convergence insufficiency-related strabismus. Whether surgery is needed depends on the type, degree, and duration of the squint. We do a thorough neuro-optometric evaluation first to tell you honestly whether vision therapy alone is appropriate for your specific situation.

Vision therapy does not cure dyslexia. Dyslexia is a language-based learning difference and needs a different kind of support. However, many children with dyslexia also have functional vision problems such as poor eye tracking or weak eye teaming that make reading even harder. Vision therapy addresses those visual inefficiencies, which can make a real difference to reading comfort even though it is not treating dyslexia itself.

Absolutely. Adults make up a significant portion of our patients. We see working professionals with digital eye strain, adults with binocular vision disorders that were never addressed in childhood, and patients recovering from strokes or brain injuries. The brain remains adaptable at any age, and many adults are surprised by how much improvement is possible.

Coverage varies a lot depending on your provider and policy. Some plans cover parts of the evaluation or certain treatments. We will walk you through the billing clearly at your consultation so there are no surprises. See our vision therapy cost guide for more details on pricing and what to expect.

Common signs include avoiding reading, losing their place on the page, headaches after school, covering one eye, squinting, poor handwriting, or seeming bright but struggling academically. Many of these children pass a routine eye chart test which only checks distance vision, not how the eyes work together. A functional vision evaluation looks at the things a standard test misses. Check our Symptoms page for a full list of warning signs.

Yes. Double vision caused by binocular vision dysfunction, convergence insufficiency, or neurological events like concussion, stroke, or traumatic brain injury often responds well to vision therapy. The key is identifying the root cause first through a proper neuro-optometric assessment. Treatment is then designed specifically for that cause rather than guessing.

Yes. If your symptoms like headaches, blurred vision after screen use, tired eyes, or difficulty staying focused are being caused by a focusing or eye teaming problem, then vision therapy can make a real difference. We see a lot of IT professionals, students, and remote workers with this exact issue. A functional vision evaluation will tell you whether your symptoms have a visual cause that therapy can fix.

Yes. Neuro-optometric rehabilitation is specifically designed for patients with visual problems following stroke, traumatic brain injury, concussion, or other neurological events. Common issues include double vision, visual field loss, balance problems, light sensitivity, and difficulty reading. We provide structured rehab programs for these patients and often work alongside neurologists and physiotherapists as part of a wider recovery team.

The main difference is diagnosis and supervision. Vision therapy starts with a thorough evaluation to identify exactly what is not working. Then a qualified optometrist designs a programme using specialised instruments, therapeutic lenses, and prisms, and monitors your progress throughout. Generic eye exercises from the internet are not tailored to any specific diagnosis and are not medically supervised. Doing the wrong exercises for the wrong condition can actually reinforce the problem rather than fix it.

Vision therapy in India costs significantly less than in the US, UK, or Australia while delivering internationally equivalent clinical standards. The cost at Caring Vision Therapy is personalised based on your diagnosis, the length of your programme, and whether you are attending in-clinic or via telehealth. We give you a clear and transparent fee structure at your initial evaluation so you can plan ahead. See our vision therapy cost guide for a detailed breakdown.

Patching is one tool, but it is not the only option and on its own it does not address the binocular vision side of amblyopia. At Caring Vision Therapy we use a multimodal approach that includes binocular vision training, monocular stimulation, and optometric syntonics phototherapy. For many patients, especially older children and adults, this approach gives better long-term results than patching alone. We assess each case individually to decide what combination of approaches is most appropriate.

The Convergence Insufficiency Treatment Trial (CITT), a large randomised clinical trial funded by the US National Eye Institute, found that 73% of children who received supervised in-office vision therapy achieved successful or improved outcomes - compared to far lower rates in home-based pencil push-up exercises and placebo groups. At Caring Vision Therapy, our supervised in-clinic therapy follows these same evidence-based protocols, which is why outcomes are consistently strong when therapy is administered by a trained specialist. See our full vision therapy success rates guide for condition-by-condition evidence.

Neuro-optometric rehabilitation is a specialist branch of vision therapy for patients whose visual problems have a neurological origin - stroke, traumatic brain injury, concussion, multiple sclerosis, or other acquired neurological conditions. Standard vision therapy primarily addresses binocular vision dysfunction and developmental vision problems in children. Neuro-optometric rehabilitation additionally addresses visual field defects, visual midline shift, photosensitivity, oculomotor impairment, and visual-vestibular integration issues arising from neurological injury. It is typically delivered alongside physiotherapy and occupational therapy as part of a multidisciplinary recovery team.

Look for optometrists with post-graduate certification from the College of Optometrists in Vision Development (COVD) or fellowship credentials from the American Academy of Optometry (FAAO). These are the internationally recognised qualifications specific to binocular vision and vision therapy. In India, FCOVD/FOVDR-certified practitioners are extremely rare. Caring Vision Therapy is one of the very few centres in the country where the lead clinician holds FCOVD/FOVDR certification, FAAO fellowship, MCOptom-UK qualification, and NORA membership - the full suite of internationally accepted credentials for neuro-optometric rehabilitation practice. We offer in-clinic evaluation in Chennai and Hyderabad, and telehealth consultations for patients who cannot attend in person.

Vision therapy does not treat ADHD itself, but it can significantly reduce ADHD-like symptoms when they are caused or worsened by an underlying visual problem. Research, including the landmark CITT study, has shown that convergence insufficiency - a very common binocular vision disorder - produces symptoms nearly identical to ADHD: inattention during reading, short concentration spans, difficulty completing near tasks, and avoidance behaviour. When this visual cause is treated with vision therapy, academic performance and attention often improve noticeably. Every child with an ADHD diagnosis should have a thorough functional vision evaluation to rule out a visual contributor. We see this regularly at our Chennai clinic.

Yes. Computer vision syndrome (CVS) - also called digital eye strain - causes headaches, blurred vision, tired eyes, and neck pain after prolonged screen use. When CVS is caused by an underlying binocular vision problem such as convergence insufficiency, accommodative dysfunction, or poor vergence flexibility, vision therapy directly treats the root cause rather than just managing symptoms. Many IT professionals, students, and remote workers at our Chennai clinic achieve lasting relief from CVS through a targeted vision therapy programme - without relying on blue light glasses or screen filters, which do not address the underlying visual mechanics.

Myopia management is a comprehensive, evidence-based approach to slowing the progression of short-sightedness (myopia) in children. It goes beyond simply prescribing glasses - it includes strategies such as atropine eye drops, orthokeratology (overnight reshaping lenses), myopia-controlling spectacle lenses, and structured outdoor time guidance. Myopia control is a broader term used interchangeably. Caring Vision Therapy offers myopia management consultation in Chennai to identify which approach suits your child's level of myopia, lifestyle, and progression rate - and to monitor and adjust the programme over time. Early intervention in childhood produces the most significant long-term benefit.

Yes, in many cases. Migraine, visual vertigo, and chronic dizziness often have a significant visual component. Binocular instability, accommodative dysfunction, and poor visual-vestibular integration can trigger or worsen migraine episodes and vertigo. Our neuro-optometric team specifically evaluates these visual contributors and provides targeted treatment including therapeutic prism lenses, visual-vestibular retraining exercises, and syntonics phototherapy. Patients with post-concussion migraine, visual vertigo, or chronic dizziness frequently respond well to vision therapy when visual factors are identified as a contributing cause.

Orthoptics is a clinical discipline focused on diagnosing and treating disorders of eye movement and binocular vision - primarily strabismus (squint) and amblyopia (lazy eye). Orthoptic techniques include prism exercises, patching protocols, and binocular fusion exercises. Vision therapy is a broader umbrella that includes orthoptic techniques alongside advanced neurological, perceptual, sensorimotor, and neuro-rehabilitative training. At Caring Vision Therapy, our practitioners integrate orthoptic principles within a comprehensive vision therapy framework - delivering the precision of orthoptic care combined with the depth of neuro-optometric rehabilitation. This integrated approach produces stronger, more lasting outcomes than orthoptics alone.

Yes. Every patient at Caring Vision Therapy receives a structured home vision therapy programme - specific exercises prescribed to consolidate weekly in-clinic gains between sessions. For patients outside Chennai and Hyderabad, we offer a fully online vision therapy programme via telehealth: remote consultation, digital exercise prescription, and video-supervised home therapy. We have delivered complete therapy programmes to patients across India and 20+ countries this way. Home-based vision therapy is most effective when designed specifically for your diagnosis and monitored by a qualified specialist - not generic exercises from the internet.

Yes. Sports vision training is a specialised application of vision therapy that improves the visual skills most critical to athletic performance: visual reaction time, dynamic visual acuity, depth perception, peripheral awareness, eye-hand coordination, and anticipation. Elite athletes in cricket, badminton, football, and combat sports benefit significantly from structured sports vision programmes. A sport vision assessment identifies which visual skills are limiting your performance, and a tailored training programme builds them systematically. We offer sports vision assessment and training in Chennai for athletes at all levels.

A Brock string is a simple but highly effective vision therapy tool: a long string with coloured beads threaded onto it at measured intervals, used while fixating on each bead in sequence. When both eyes are working together correctly, you see two strings forming an X or V shape at the bead you are looking at - this is the normal binocular response. If one eye is suppressing or the eyes are not properly coordinated, the X pattern breaks down or disappears. The Brock string is used to diagnose and treat convergence insufficiency, divergence excess, suppression, and poor eye teaming. It is one of the oldest and most research-validated vision therapy tools still in active clinical use. At Caring Vision Therapy, Brock string exercises are prescribed as part of supervised in-clinic therapy and as home practice where appropriate for the patient's programme.

Convergence exercises are vision therapy activities that train the eyes to turn inward correctly when looking at near objects - the movement required for reading, writing, and all sustained close work. Convergence insufficiency is one of the most common binocular vision disorders and causes symptoms including headaches, eye strain, double vision, words shifting on the page, and difficulty sustaining focus during reading or screen work. Clinical convergence exercises include Brock string work, dot-card exercises, barrel cards, stereoscope procedures, and computer-assisted vergence training. The Convergence Insufficiency Treatment Trial - the largest randomised controlled trial in this field, funded by the US National Eye Institute - found that supervised in-office convergence therapy produced successful outcomes in 73% of children, compared to far lower rates with home-based pencil push-up exercises alone. At Caring Vision Therapy, convergence rehabilitation is among our most frequently treated conditions and most patients complete a structured programme within 16 to 24 weekly sessions.

Home exercises can provide some benefit for mild convergence insufficiency, but the clinical evidence is clear: in-office vision therapy produces significantly better outcomes than home exercises alone. The CITT (Convergence Insufficiency Treatment Trial), the definitive randomised controlled trial funded by the US National Eye Institute, found success rates of 73% for in-office vergence therapy versus 33% for pencil push-up exercises done at home. That is more than twice the success rate.

Why the difference? In-clinic therapy uses specialised instrumentation (prism bars, stereoscopes, vectograms, computer-assisted vergence systems) that challenge the convergence system in graded, progressive ways that cannot be replicated at home. The therapist also monitors your responses in real time and adjusts the difficulty and sequence of procedures based on objective binocular feedback - something no home programme can provide.

Home exercises that are commonly prescribed as part of a supervised programme (not as a standalone treatment) include: pencil push-ups (tracking a pencil tip from arm's length slowly toward the nose until it doubles), Brock string exercises (threading coloured beads on a string, fixating on each in sequence while maintaining the binocular X-pattern), dot card exercises, and barrel card fixation. These home activities are valuable as a complement to weekly in-office sessions - reinforcing the neural changes being built in the clinic. When used as a substitute for in-clinic therapy, their effectiveness is limited and the research confirms this.

For adults and children with moderate to severe convergence insufficiency, or for anyone whose convergence insufficiency is causing significant reading difficulty, headaches, or double vision, in-clinic therapy at a FCOVD/FOVDR-certified centre is the appropriate evidence-based treatment. Home exercises may be suitable for very mild cases or as a maintenance strategy after completing a full clinic programme. At Caring Vision Therapy in Chennai and Hyderabad, we assess severity at evaluation and advise honestly on the level of intervention needed.

Choosing the right vision therapy clinic in Chennai is important because the quality and structure of the programme directly affects your outcomes. Here are the criteria we recommend you evaluate before committing to any centre:

• COVD certification: The College of Optometrists in Vision Development (COVD) is the international gold standard certification for vision therapy practitioners. A COVD Fellow or Member has completed rigorous post-doctoral training, passed clinical examinations, and demonstrated competence in binocular vision rehabilitation. Caring Vision Therapy is FCOVD/FOVDR Fellow & Member certified - one of the very few in India.
• Comprehensive initial evaluation: A credible vision therapy clinic begins with a 60 to 90 minute functional vision evaluation - not a 10-minute screening. If a clinic offers to start therapy without a thorough diagnostic evaluation, that is a red flag.
• Personalised programme design: No two patients have the same diagnosis. A quality centre creates an individualised therapy programme based on your specific binocular vision assessment results - not a generic protocol.
• Evidence-based protocols: The clinic should use clinical procedures validated by peer-reviewed research (CITT, ATOM2, BVAT, NORA protocols), not proprietary exercises with no scientific basis.
• Transparent outcomes reporting: Before-and-after binocular vision testing data, not just subjective symptom reports, should confirm your progress at regular intervals.
• Dedicated vision therapy practice: A clinic that offers vision therapy as one service among many (alongside glasses, contact lenses, LASIK, etc.) is fundamentally different from a centre exclusively dedicated to vision therapy and neuro-optometric rehabilitation.

Caring Vision Therapy is India's only exclusively dedicated vision therapy and neuro-optometric rehabilitation centre with FCOVD/FOVDR international board certification, FAAO and MCOptom credentials, and NORA affiliated membership. We have treated over 20,000 patients across 20+ countries.
