What are the benefits of Trataka?
Trataka, the yogic practice of gazing steadily at a candle flame or another fixed point, has a small but real evidence base. The best-studied benefits are less visual fatigue in heavy screen users, sharper attention right after a session, better scores on short working-memory tasks and less mind-wandering, although each rests on small, short studies.
A calmer heart rate, lower anxiety and better sleep have promising early signals, but those studies are too small or too loosely controlled to count as established.
Several popular claims are unsupported or untested. Trataka has not been shown to improve eyesight or reverse myopia, cure eye disease, treat ADHD or open a "third eye".
This guide sorts each common claim by the strength of the evidence behind it, links every study, and ends with a simple way to test the practice for yourself. For an introduction to the technique itself, start with the Trataka meditation guide.
How strong is the evidence for Trataka overall?
Promising, but early. A 2025 systematic review of Trataka and cognition describes the practice as promising for the mind, eyes and brain. It also notes that the studies vary widely in method and that direct evidence for how Trataka works is limited (Roj et al., 2025).
Three patterns run through the research:
- The studies are small. Most enrolled between 24 and 120 people. The largest trial had 300.
- The follow-up is short. Interventions lasted from a single session to eight weeks. Reviewers keep asking for larger studies with long-term follow-up (Chetry et al., 2023).
- The comparisons are uneven. Some trials compared Trataka with an active alternative such as eye exercises or relaxation training. Others compared it with no practice at all, or bundled gazing with breathing, chanting or meditation, which makes it hard to credit the candle alone.
Participants always know whether they are doing Trataka, and many outcomes are questionnaires or short lab tasks, so expectation can shape results. None of this makes the findings worthless. It means the honest question is "what was measured, in whom, and for how long", not "what does Trataka do".

Which Trataka benefits have the best evidence?
"Best" is relative here. The findings below come from controlled studies, but those studies are still small and short.
Less eye strain and visual fatigue from screens
This is the most-studied benefit, which surprises people who assume steady gazing must strain the eyes. The results are encouraging but not settled.
In a 2022 randomized controlled trial, 106 volunteers who used digital displays for long periods were split evenly between two weeks of Trataka and a control group. On standardized questionnaires, the Trataka group reported less visual strain and less mind-wandering, along with higher state mindfulness (Swathi, Saoji and Bhat, 2022).
A larger 2024 trial randomized 300 IT professionals with computer vision syndrome to two weeks of Trataka, cold eye packs or a waitlist. Both Trataka and cold eye packs improved self-rated visual strain and fatigue compared with the waitlist, and neither beat the other (Saoji et al., 2024). Trataka helped in that trial, but no more than a simple cold compress.
A 2026 systematic review and meta-analysis found 21 relevant studies and pooled three of them. Visual fatigue scores fell significantly within Trataka groups, but the difference from control groups was not statistically significant, and the authors called the evidence limited and inconclusive (Shetty, Kamath and Annapoorna, 2026).
Why would a gazing practice ease eye strain? The Trataka protocols we could check in detail, such as the 2021 memory study below, pair the gaze with eye exercises, closed-eye visualization or relaxation. Every session is also a break from the screen. The benefit may come from the whole routine rather than from the fixed gaze alone. For the wider picture on screen fatigue, see whether gaze training can reverse screen attention damage.
Sharper attention right after a session
In a 2016 study, 30 healthy young men completed the Stroop color-word test after a Trataka session and after a control session. Performance was better after Trataka, which the authors interpreted as improved selective attention, cognitive flexibility and response inhibition (Raghavendra and Singh, 2016). The Stroop test asks you to name the ink color of a word while ignoring the word itself, so it measures how well you override an automatic response.
Research in younger people points the same way. A randomized study of 80 adolescents found better Stroop scores and lower anxiety after a program combining meditation, eye exercises and Trataka, compared with a group that kept its usual routine (Sherlee and David, 2020). Because the program bundled three practices, it cannot show which one did the work.
The clearest single-session studies measured performance soon after practice, not a week later. That is why Trataka fits best as a short warm-up before demanding work. The five-minute Trataka warm-up for deep work turns this into a routine you can test.
Better performance on working-memory tasks
Working memory is the mental workspace you use to hold and manipulate information for a few seconds, like keeping a phone number in mind while you dial it.
In a 2021 study of 41 healthy, yoga-experienced young adults, a Trataka session improved forward performance on the Corsi block-tapping task, a test of visuospatial memory. It beat both baseline and an eye-exercise session, and forward span rose from an average of 5.5 to 6.1 blocks. The harder backward version of the task showed weaker results (Swathi, Bhat and Saoji, 2021).
A 2014 trial began with 60 adults aged 60 to 80. Digit span improved within the group that completed 26 days of a multi-part Trataka program, although the difference from the wait-list group was only a trend. The clearest difference between groups was on a mental-flexibility task, the Trail Making Test B (Talwadkar, Jagannathan and Raghuram, 2014).
None of this shows better long-term memory, learning or grades. Our full review of Trataka and working memory walks through these numbers and their limits.
Less mind-wandering
The same 2022 screen-user trial that measured eye strain also found less mind-wandering and higher state mindfulness after two weeks of Trataka (Swathi, Saoji and Bhat, 2022).
That fits the practice's core mechanic. You keep returning attention to one point, and each return is a small repetition of noticing that your mind has drifted. Still, this is one trial measured by questionnaire, so treat it as a promising signal. If a restless mind is your main problem, how Trataka helps calm the monkey mind covers the practical side.
Which benefits are promising but preliminary?
These findings are interesting enough to mention and too thin to rely on. Each rests on a small study, a single session, a special population or a design without a proper control group.
A calmer heart rate, breathing rate and blood pressure
In a 2014 study of 30 healthy men, breath rate and heart rate fell after a Trataka session but not after a control session. The authors read the heart rate variability data as a shift toward calm, with more vagal tone and less sympathetic arousal (Raghavendra and Ramamurthy, 2014).
A 2021 randomized trial of 60 adults with primary hypertension found that Trataka significantly lowered systolic blood pressure and heart rate right after the practice, with no significant change in the control group (Kusuma et al., 2021).
These are short-term changes measured right after practice. They do not show that Trataka lowers blood pressure over months, and Trataka should never replace prescribed treatment.
Less anxiety
A 2024 randomized trial enrolled 120 children aged 8 to 11 who needed local anesthesia for dental treatment. After four weeks of training, the Trataka group showed a greater drop in anxiety scores than a group taught relaxation techniques (Pandya, 2024).
The adolescent study above also reported lower anxiety, but its program combined Trataka with meditation and eye exercises. Both studies involved young people, and neither shows that Trataka treats an anxiety disorder in adults.
Better sleep
In a small study, 29 people with insomnia practiced Trataka for 45 minutes a day for 10 days. Their scores on the Insomnia Severity Index and the Pittsburgh Sleep Quality Index improved significantly (Shathirapathiy, Mooventhan et al., 2020).
There was no control group, so the improvement could reflect time, expectation or simply a calming evening routine. A 45-minute daily session is also far longer than most home practice. If you try Trataka before bed, never leave a flame burning when you are drowsy, and get a medical assessment for sleep problems that persist.
Lower eye pressure in glaucoma: conflicting results
A 2022 randomized trial studied 60 people aged 52 to 67 with type 2 diabetes and high-tension primary open-angle glaucoma. Alongside their usual diabetes medication, half practiced Jyoti-Trataka for 55 minutes a day for a month, gazing at a candle flame about four feet away. That group showed significant reductions in eye pressure, blood pressure and fasting blood glucose, while the control group showed no significant change (Ismail et al., 2022).
A second randomized trial, run at the All India Institute of Medical Sciences, points the other way. It added four weeks of modified Trataka, eye exercises, Om chanting and breathing practice to the usual treatment of 72 glaucoma patients. Eye pressure did not differ significantly from the control group, and the authors concluded that the practice cannot be recommended for managing raised eye pressure (Sankalp et al., 2022).
A 2023 systematic review of yoga and eye pressure in glaucoma found improvement signals for some practices, including Jyoti-Trataka. It also found that inverted postures raised eye pressure quickly, and it called for larger and longer studies (Chetry et al., 2023).
This is not a reason to self-treat glaucoma. If you have glaucoma or high eye pressure, talk to your ophthalmologist before trying any gazing practice, and never stop prescribed treatment.
Which Trataka benefits are not supported?
Better eyesight or curing eye disease
The Hatha Yoga Pradipika, a 15th-century hatha yoga manual, credits Trataka with eradicating eye diseases, fatigue and sloth (read a translation). The little modern testing available does not support the eyesight part of that promise.
In a 2018 randomized study, 24 people with myopia (48 eyes) practiced either Bates eye exercises or Trataka for eight weeks. Neither method significantly reduced refractive error or improved visual acuity (Tiwari et al., 2018).
If your vision is blurry, see an optometrist. Trataka is not a substitute for glasses, contact lenses or medical eye care.
Treating ADHD
Trataka exercises skills that ADHD affects, such as holding attention on one thing and resisting distraction, which is why the idea appeals. But we could not find a published trial of Trataka in people diagnosed with ADHD. The studies in this guide involved healthy adults, older adults, adolescents, children facing dental treatment and patients with other conditions.
Our evidence review on Trataka for ADHD covers what is reasonable to try alongside established care, not instead of it.
Opening the third eye or gaining psychic abilities
In yogic tradition, Trataka is linked with the point between the eyebrows, often called the third eye, and with inner vision. These are spiritual ideas, not measurable outcomes, and no study has tested them. If the tradition matters to you, it can give your practice meaning. It should not be presented as a proven benefit.
Why might Trataka have these effects?
Researchers have proposed several explanations. None has been confirmed directly.
- Attention training. Each time you notice your gaze or mind drifting and return to the flame, you rehearse the same control process used to resist distraction. This fits the Stroop and mind-wandering findings.
- A shift toward calm. Lower heart and breathing rates after practice suggest a more relaxed physiological state, which could help explain the anxiety and sleep signals.
- Visual and eye-movement effects. Steady fixation engages the systems that control where the eyes point. The 2025 review proposes a model linking sustained gaze to attention networks, but presents it as a hypothesis to test rather than an established mechanism (Roj et al., 2025).
How can you test Trataka's benefits for yourself?
Research tells you what happened on average in small groups. A two-week personal experiment tells you whether Trataka helps you.
- Pick one outcome. Choose the benefit you care about most, such as eye fatigue at the end of a screen day, how long you can read before your mind drifts, or how long it takes you to fall asleep.
- Take a baseline. Rate or time that outcome for three to five days before you start.
- Practice briefly and consistently. Start with two to four minutes a day, with the candle at eye level about an arm's length away. Blink when you need to, then close your eyes and rest. The beginner's guide covers setup, and the session-length progression shows how to build up.
- Run it for two weeks. That matches the length of the main eye-strain and mind-wandering trials.
- Compare honestly. If your measure has not moved after two weeks, Trataka may not be the right tool for that problem.
Keeping the log is the part most people drop. If you want a tool that tracks your progress over time, guided sessions with blink feedback and a session history can handle the timing and record-keeping for you.
Who should be cautious with Trataka?
Short, sensible practice appears low risk for healthy adults, but steady gazing is not right for everyone:
- Glaucoma, retinal disease or recent eye surgery: get clearance from an eye doctor first.
- Photosensitive epilepsy: avoid flickering flames, use a static, non-luminous target such as a black dot, and check with your doctor.
- Dry eyes or contact lenses: keep sessions short and blink freely.
- Children: always supervise an open flame.
Stop if you feel eye pain, get blurred vision that does not settle, or develop headaches. Our full guide covers whether Trataka is dangerous and how to practice safely.
Frequently asked questions
What is the main benefit of Trataka?
The most-studied benefit is less visual fatigue in people who spend long hours on screens. Two randomized trials found improvements, but in one of them cold eye packs worked just as well, and a 2026 meta-analysis judged the pooled evidence inconclusive. Short-term gains in attention and working-memory tasks are the other consistent findings.
How long does it take to see benefits from Trataka?
Some studies found changes in attention and working-memory tasks immediately after a single session. The eye-strain and mind-wandering trials ran for two weeks. Research has not yet shown how long any benefit lasts after you stop practicing.
Is Trataka good for your eyes?
For screen-related eye strain, the early evidence is encouraging but not conclusive. For eyesight itself, the one randomized test found no improvement in myopia. People with glaucoma, retinal disease or recent eye surgery should get medical advice before starting.
Does Trataka improve memory?
Small studies found better scores on short working-memory tasks after Trataka, mainly for forward visuospatial span. There is no evidence yet that it improves long-term memory, learning or grades.
Can Trataka help you sleep?
Possibly. One 10-day study of 29 people with insomnia found better sleep scores, but it had no control group. Treat evening Trataka as a calming routine to test, not as a treatment for insomnia.
Are candle gazing and Trataka the same thing?
Candle gazing is the most common form of external Trataka. The practice can also use a dot, a symbol or another fixed point, and an internal form involves holding the image in mind with the eyes closed.
How many minutes of Trataka should you do a day?
There is no proven ideal dose. Our progression starts at two to four minutes a day in the first week. Research protocols ranged from about 10 minutes of gazing within a 20-minute session to 55 minutes a day in a glaucoma trial.
