Symptoms and breaks
Exercises
None of these is shown to lower your prescription. Each tag says how much evidence there is for the exercise itself. A finished run is logged, but it is not a break and does not count toward the streak.
On myopia: the American Academy of Ophthalmology says "there is no scientific evidence to suggest that eye exercises, vitamins or pills can prevent or cure myopia" (Nearsightedness: What Is Myopia?, 12 Jan 2026). A 2024 meta-analysis of 11 controlled trials (Lin et al., Eye; full text read) has one pooled result favouring exercise, a "protective/mitigating effect" with risk ratio 0.40 (95% CI 0.23–0.71). Three of its seven studies counted eyes, not people, without allowing for two eyes belonging to one person. Without them it is 0.53 (95% CI 0.18–1.59, P = 0.26), no longer significant. Refractive error did not differ (SMD −1.74, 95% CI −6.27 to 2.79), no study measured eye length, and all but one study was of children. The authors conclude that eye exercises have "limited to no efficacy in preventing or controlling myopia progression".

The 2 h target
This is a children's figure, and it was set to stop myopia starting, not to slow it. China's 2018 national plan (教体艺〔2018〕3号) says children should get more than 2 hours of outdoor activity a day. The best trial, He et al., JAMA 2015, added 40 minutes of outdoor class a day for 3 years: 30.4% of first-graders who were not myopic at the start became myopic, against 39.5% without the extra time.
For someone already myopic the evidence is weak. A 2017 meta-analysis (Xiong et al.) found no effect of outdoor time on progression in eyes that were already myopic. A 2024 Cochrane review (Kido et al.) says it is uncertain whether more time outdoors reduces progression. No trial of outdoor time in adults was found, only observational studies.
Treat 2 h as something to aim for, not a dose shown to work for an adult. This page counts your time and promises no result. The trials were read as abstracts, and the Chinese plan through a repost.
Rx
One entry per eye exam, copied from the slip. Prescriptions stay in this browser's storage and never go into the app's code.
Log an exam
Next dilated exam
Every 12 months is this app's choice. The guidelines disagree. The American Optometric Association's 2023 guideline recommends a comprehensive eye exam every year from age 18 to 64 (AOA, 8 Mar 2023). The American Academy of Ophthalmology advises an exam every 5 to 10 years under 40, for adults without risk factors (AAO Preferred Practice Pattern). A trade report says the AAO's 2026 update asks for a yearly dilated exam at −6.00 D or worse, or an eye longer than 26 mm (Review of Optometry, Feb 2026). The guideline itself wasn't read, so this app doesn't rely on it. Ask your eye doctor which interval applies to you.
Trend
Log two exams to see a trend.
The ±0.50 D band is an assumption, rounded up from one study. Otero et al., J Optom 2019 refracted the same eyes in two sessions within a week. For a standard clinical refraction, the SE of right eyes varied with a standard deviation of 0.13 D. That puts 95% of repeat pairs within about ±0.36 D (2.77 × 0.13; this calculation is the app's, not the paper's). Exams by different examiners or clinics probably vary more, but no figure for that was verified. Only the abstract was read.
Exams
No exams logged.
SE, the spherical equivalent, is sphere plus half the cylinder: one number per eye, so exams can be compared.
Get care right away
Go to your eye doctor or an emergency room right away if you notice any of these:
- a lot of new floaters: small dark spots or squiggly lines that drift across your vision;
- flashes of light in one eye or both;
- a dark shadow or "curtain" at the side or in the middle of your vision.
These can mean a retinal tear or detachment. The National Eye Institute calls a detachment a medical emergency and says its symptoms often come on quickly. It also says a small detachment may cause no symptoms. It lists extreme nearsightedness, especially degenerative myopia, as a risk factor, but gives no figure for how much the risk rises.
Facts
What the evidence says, quoted from the source and linked. Each card says whether the full text or only the abstract was read.
What can and can't lower the number
No home method has been shown to lower a myopic prescription. Drops and special lenses slow its growth, in children, and do not reverse it. Surgery changes the number but not the eye's risks.
Tested, and didn't work
- Eye exercises. The American Academy of Ophthalmology says nearsightedness "cannot be corrected with eye exercises" (Coats, AAO, 10 Mar 2014). A 2024 meta-analysis of 11 trials found "limited to no efficacy" (full text read; details on the Exercises page).
- The Bates method. 15 myopic adults, aged 18–53, were randomly given 3 weeks of Bates-style training or a control routine. There were "no statistically significant changes in refractive error with either form of treatment" (Thompson et al., Aust Orthopt J 2004; abstract read). Small and short, and the only trial found.
- Pinhole glasses. 15 myopes wore them for near work for 3 weeks. Their refractive error did not change (right eye p = 0.08, left p = 0.09) (Che Azemin & Che Arif, Int J Allied Health Sci 2018; abstract read). There was no control group, and no larger trial was found.
Slows it, in children
- Atropine drops and myopia-control lenses: multifocal soft contacts, peripheral-plus and multifocal spectacles, orthokeratology. A 2025 Cochrane review of 104 trials in 17,509 children aged 4 to 18: "These interventions may slow refractive change and reduce axial elongation, although results were often heterogeneous. Less evidence is available for two years and beyond" (Lawrenson et al.; abstract read). High-dose atropine rated best: 0.90 D less change than controls in a year (95% CI 0.62–1.18, moderate certainty). Most of the others were rated low or very low certainty.
- Slower, not lower. The AAO says these treatments "will not reverse the myopia you already have. They only keep your myopia from getting worse" (Bensinger, AAO, 2 Sep 2020).
- Adults are untested. The review took children only, and one search found no adult trial of atropine or these lenses. Adult eyes can still change, though: of 691 people examined at 20 and again at 28, 37.8% had a myopic shift of 0.50 D or more in at least one eye (Lee et al., JAMA Ophthalmol 2022; abstract read).
LASIK changes the number, not the risk. It works "by reshaping the cornea" (AAO). The International Myopia Institute says that after corneal surgery or lens procedures in a highly myopic eye, "the refraction of the eye may be normal, but the risk of pathologic myopia remains" (IMI, Flitcroft et al., 2019; IMI's web copy read, not the journal article). Whether LASIK leaves the eye's length exactly as it was is not settled here: one pilot of 10 eyes measured changes of 0.04 to 0.32 mm a month after surgery (Chalkiadakis et al., Clin Ophthalmol 2010; full text read), and no larger study was found.
When myopia counts as high
There is no single line. The WHO draws it at −5.00 D, the International Myopia Institute at −6.00 D.
WHO: "the spherical equivalent objective refractive error is ≤ –5.00 D in either eye". It chose that line because uncorrected vision at −5.00 D is 6/172, "much worse than the threshold for blindness". The same report says "there is currently no internationally agreed threshold" (WHO–Brien Holden Vision Institute, The impact of myopia and high myopia, 2016; part read, from a mirror copy).
IMI: "≤ –6.00 D when ocular accommodation is relaxed", for each eye on its own. It chose −6.00 D "for consistency with the lower threshold for myopia", and says "there is no clear biological basis" for any cut-off (IMI, Flitcroft et al., 2019; web copy read in full).
So between −5.00 D and −6.00 D an eye is high myopia by one definition and not by the other. Neither line marks a point where risk jumps. Your spherical equivalent for each eye is on the Rx page.
Screen setup
About 50–70 cm away. The top of the screen at or below eye level. Brightness matched to the room.
- Distance. The American Optometric Association says "20 to 28 inches from the eyes", which is 51–71 cm (AOA). The same page also gives 16 to 30 inches elsewhere. OSHA gives a wider range: "between 20 and 40 inches (50 and 100 cm)".
- Height. "Place monitor so top line of screen is at or below eye level" (OSHA). The AOA puts the centre of the screen 15 to 20 degrees below eye level.
- Brightness. "Adjust your screen brightness to match the level of light around you" (AAO, 27 Jun 2024).
These are guidance pages, not trial results. They say what is comfortable, not what is proven to reduce strain, and nothing here touches myopia itself. All three pages were read in full.
Blue-light lenses
They may not reduce eye strain from screen work. The evidence is low-certainty and short.
A 2023 Cochrane review of 17 trials: "There may be no difference in subjective visual fatigue scores with blue‐light filtering lenses compared to non‐blue‐light filtering lenses, at less than one week of follow‐up (low‐certainty evidence)" (Singh et al.). The number behind that is one trial of 120 people: 9.76 units worse with the lenses, 95% CI −33.95 to 53.47, an interval wide enough to include no difference at all. Its key message: blue-light lenses "may not reduce short‐term eyestrain associated with computer work".
"May", not "probably". The review says "probably" only for its moderate-certainty finding, on sharpness of vision. Eye strain was rated low. The abstract and plain-language summary were read, from the full text on PubMed Central.
Settings
Theme
System follows your OS setting and switches when it does.
Anything logged before this hour counts toward the day before. Set it past the time you usually stop, so a late session lands on the day it began.
Break reminders
These are also your desk days. The streak counts only them; other days are neither done nor missed.
A change here re-scores past days too. Tick Saturday and every past Saturday becomes a miss; untick it and they are off again.
Check-in nudge
Once a day, only while the app is open, and not at all once the check-in is saved. A system notification when they're allowed, otherwise a note inside this window. Quiet hours don't apply: you chose the time.
Storage
Saved in this browser under vis.v1, schema v. Sync, below, copies records out; a backup file is the copy that doesn't depend on Turso.
The backup has every record and your settings. It leaves out the Turso token and a running outdoor timer. Restore only adds records or swaps in a newer copy of one you already have, so it can't delete anything; with the box ticked it overwrites settings, except the reminder and nudge switches, which stay as this device has them. Tick the box before you pick the file.
CSV, for a spreadsheet
Removed entries are left out. Outdoor entries added with +15 min are marked estimate = yes. Exercises are in the backup only.
Sync
Copies your logged records (breaks, check-ins, exercises, outdoor time, Rx) to your own Turso database, so the laptop and the phone see one history. Settings, a running outdoor timer and this token never leave this device.
Both values come from Turso. The URL starts with libsql://; create a read-write token for this one database. The CLI gives them with turso db show <db> --url and turso db tokens create <db>. The dashboard should show both on the database's page; those steps were not checked against Turso's docs, the two commands were.
Sync stays off until Test connection passes. Editing the URL or token turns it off again.
The token sits unencrypted in this browser: anyone with this browser profile can read it. To revoke it, run turso db tokens invalidate <db>, which revokes every token for that database's group.
