Every page describing blinking exercises for dry eyes mentions approximately the same routine, and none cites the randomised trial which tested it. Two quote a figure for the reduction in blink rate caused by a screen, neither mentioning the source, and the longest at 4200 words cites "recent research from 2025" four times without specifying any paper.
There is a paper. It is short, recent, and includes two findings which bear directly on the recommended eye-care regimen following a day's work at a computer, which is presumably the context in which most people would perform blinking exercises.
Neither of these findings are mentioned on any of the pages describing blinking exercises for dry eyes.

What screens actually do to your blinking
Blinking at a screen causes two distinct problems: decreased blink rate, and an increased rate of incomplete blinks. The latter is connected to symptoms in a way the former is not, though both are frequently mentioned in the same breath. The numbers from the 2013 study in Optometry and Vision Science are lower than the figures quoted in the blinking exercises pages, but are more informative.
A group of 21 subjects was video-recorded for a continuous 15-minute desktop reading task at a distance of 50 cm, with blink rates assessed for each subject (PubMed). Mean blink rate for all subjects during the task was 11.6 blinks per minute. The mean percentage of incomplete blinks was 16.1%, ranging from 0.9% to 56.5% for individual subjects with a standard deviation of 15.7 from the mean.
Symptom score was correlated with percentage of incomplete blinks (p = 0.002).
These are small effect sizes in a sample of 21 subjects measured over a span of 15 minutes, and the paper itself notes that the task is not representative of a typical workday. What it does show is that partial blinks are both common and highly variable between subjects.
You will find references to a resting rate of fifteen-to-twenty blinks per minute on nearly every page describing the condition. They are not in this one, or either of the others below, so I am happy not to cite them, and nobody else should either.
Blinking more often is not the answer
The same 2013 study investigated the obvious remedy and found it wanting - a tone sounded every four seconds raising them from 11.6 to 23.5 per minute on average. Symptom scores were unaffected.
The authors' suggested mechanism for the ineffectiveness of their test was that 'completeness' of the blink might be more important than frequency, and that simply telling a patient to blink more would rarely be practical.
Two caveats should be made to this conclusion. The tone was tested as a short-term intervention in the same brief laboratory session, rather than as a long-term treatment; this is a failure of proof of concept rather than a refutation of the usefulness of increasing blink rates as a treatment. Secondly, while the article suggests the impracticality of asking patients to blink more often, it might be better phrased as evidence of the absence of evidence.
It is the only trial ever performed on the efficacy of this kind of intervention, and one that failed to find an effect. Doubling one's blink rate is not a viable treatment for dry eye.
The routine that was actually tested, and what it moved
There has been one randomised controlled trial investigating the efficacy of various 'blinking exercises', including a dose-finding analysis to determine which protocol to use in the main trial. The result of this analysis was a prescription of fifteen close-squeeze-open cycles, three times per day. This reduced both symptom scores and the proportion of incomplete blinks, and had no effect on objective measures of tear film function, as the authors state clearly.
The main trial, published in 2025 in Contact Lens & Anterior Eye, involved 98 patients and was performed in two stages (PubMed). In the first stage, the variables tested were squeezing versus not squeezing, number of sessions per day (two to four), and number of cycles per session (five to twenty-five), tested using an instructional app.
Blinking exercises reduced symptom scores (p < 0.01), and the addition of squeezing reduced symptom frequency (p < 0.01). Forty cycles split between two sessions was better than ten cycles per session for symptom frequency (p = 0.015), and fifteen better than five cycles per day for that same measure (p = 0.008).
The second stage tested that optimized routine in 28 patients with dry eye disease for two weeks. The results showed that the participants' symptoms were reduced (p = 0.001), the frequency of symptoms was reduced (p = 0.027), the number of incomplete blink was reduced (p < 0.001), and the conjunctival staining was reduced (p = 0.041).
Now, proceeding to the other part of the same study, where the other half of the research is presented.
The study observed that there was no significant difference in blink rate, non-invasive tear breakup time, Tear meniscus height, or corneal staining between the groups at(p > 0.05). The exercises had an effect on the perception of the patients' eyes and their ability to close their eyelids, but they did not have an effect on objective measures of the tear film typically found in a medical clinic, meaning that this is an intervention with a mechanism but no therapy, which the trial authors do not necessarily disagree with.
The cycle was to close the eyelids gently as if falling asleep and hold it for a moment, move to the next step: to close the eyes tighter and open them. It is in this act of closing more tightly that the meaningful effect on symptom frequency was hidden.
Twenty-eight patients, two weeks of treatment, and an app not compared to a sham procedure, not to standard care, but to nothing else, constitute the entire evidence base for the trial, which is considerably lighter than the confidence with which the routine is promoted on the Internet.
The finding that changes how you should think about it
Two weeks after participants discontinued the exercises, gains across all the measures were found to be largely reverted to the baseline level (p > 0.05). The trial reports on this fact in the same paper, as a detail pertaining to the positive result, which makes the intervention a habit one continues indefinitely, and not something that one does until a stop date, and also constitutes, in combination with the positive result, the single most important sentence in the study for the purpose of making the decision to participate.
Take it as brushing your teeth and not as a pill with an expiration date.
In practice, it means anchoring the sessions to existing rituals instead of a phone alarm one is likely to snooze on Monday through Friday. Getting it done once before the morning coffee, once after lunch, and once when the laptop is powered down for the day, is likely to be more effective than trying to fit it in somewhere around 4 PM when the mind is already elsewhere. A session can be concealed almost anywhere without attracting suspicion.
Palming, eye rolling and "eye yoga", graded honestly
Being able to palm something like that is convenient, effortless, and completely safe, and the lack of evidence of negative consequences is not exactly a negative claim, it is simply an observation that has not been made yet.
Rubbing your palms together and cupping them over closed eyes after two hours of gazing into a laptop screen is everyday advice in India. It is taught in yoga class along with breathing, in school assembly, in corporate relaxation sessions, and on every second eye-hospital blog. No one is keeping it secret, so there should be no mystery about it.
The only controlled trial that includes it as an intervention is a 2020 study in the International Journal of Yoga, on 32 undergraduate optometry students with symptoms, 16 in each group (PubMed). The treatment group performed a ten-step instructor-led routine, including palming, for 30 minutes per day, five days a week, over six weeks. Eye fatigue questionnaire scores fell in that group (p = 0.003) and rose in the control group (p = 0.044).
Look at the trial design before you read the conclusion.
Palming was only one of ten steps, the first of which was blinking, an intervention in itself supported by one trial. It is impossible to say what changed things based on this information, only that the whole package most likely did not do so dramatically.
Only one outcome measure was used, a questionnaire. There was no objective test of eyesight in either group. The control group received no treatment at all versus 30 minutes of personal instruction for the treatment group. Questionnaire results are known to be easily biased by suggestion. The sample size was small, relevant only to a single university. The paper has no limitations section, and the authors hedge their language when discussing the possible mechanism.
Rolling one's eyes sideways, looking from near to far and back, and focusing on one's own reflection. If you want to do this exercise, there is no harm in it. It is even a good idea if you find it relaxing after a long day of staring at screens. It is malpractice if branded as a specific treatment for eye fatigue, and no web page listing various eye relaxation techniques side-by-side is being completely honest about them all.
Warm compresses, breaks, and the rest of the resting routine
A warm cloth on your eyes is the sort of advice an eye doctor would give, and most people already do something like that. No trial has been tested for this entry, and if someone gives you a percentage for it, they're making it up. It's completely free and most people would enjoy the sensation, and if you're already eleven at night, that's probably a good amount of motivation right there.
Forced air over your face is worth looking into before blaming your blinking, and a fan pointed directly at you or the air conditioning vent in your office directly over your head is free. That's the cheap fix on this list, and it's not even up for debate.
Taking breaks from screens is the other half of the argument, and rather than a bullet point on their own, they get their own long-winded paragraph: a ten minute argument for them if you've been doing the twenty-twenty-twenty rule religiously.

What this actually adds up to
Three sets of fifteen close/open blinks, with a quick squeeze in the middle, is the only routine mentioned that has a proper dosage to back it up, and the blinking itself has nothing to prove its worth besides the recommendation. Palming is a nice recommendation, and only that.
None of the trials above measured whether any of this corrects eyesight, improves a refractive error, or undoes hours of screen time, and a resource that tells you otherwise is going beyond what these papers actually tested.
Keep an eye on the boundary. Persistent redness, pain, discharge, light sensitivity or blurring that does not clear when you look away from the screen is not a blinking problem, and the correct next step is an eye doctor rather than another exercise. Screen-related dryness and fatigue tend to ease with rest, changed habits and time.
All things considered, this routine is quick, has one small trial behind its dose, and needs upkeep to keep working. Whether that trade is worth three sessions a day is the part left for you to weigh.
