How do I look after my eyes and ears without buying gadgets?

Three pages in this library are about eyes and ears, and each one says the fix is free and the thing sold for it mostly is not. Look out the window every twenty minutes is the afternoon ache at a screen. The earplugs make the band sound better is the pair handed out at the door that went into your pocket. What the captions actually fix is the setting that went from accessibility feature to ordinary habit. Two of them put a line first that is not about habit at all.

Every twenty minutes, look far and blink. Match the screen to the room. Look out the window every twenty minutes says that by three in the afternoon your eyes feel sanded, you have probably been told this is blue light, and probably been offered amber glasses for it. The page starts with what is happening, from the American Academy of Ophthalmology: there is no scientific evidence that the blue light from screens damages your eyes, and people blink far less often at a screen than they normally do, roughly five to seven times a minute instead of about fifteen. Dry eyes, and focusing muscles held at one near distance for hours, are the whole mechanism of the ache, and neither is damage. Three separate conversations arrive at the first fix from experience: blink on purpose, and use lubricating drops, the kind sold as artificial tears, when they feel dry. The rule that runs through the conversations and the Academy alike is twenty-twenty-twenty, every twenty minutes look at something at least twenty feet away for twenty seconds; one person points out that the numbers are arbitrary and the principle is not, another sets a timer, a third uses software that blanks the screen briefly, and one sits with their back to the office door so every person walking in forces a far look and a neck turn. The honest objection is on the page too: a hard break every twenty minutes wrecks deep work, and some jobs, a service desk, a monitored floor, do not allow it; the accounts who work that way say the parts that survive are the blinking, the drops, the brightness and the distance, which need no permission. On the glasses, the page says the eye doctors have answered: the Academy does not recommend blue-light-blocking eyewear for computer use, and if a pair makes your day feel better nobody there will take them off you, but the accounts that found relief in them were usually also doing the things that work. Brightness first: two separate conversations describe turning the screen down by a third or more and finding the strain eased, and one person’s test is to hold a sheet of white paper beside the screen and lower the brightness until a white page on the monitor matches it, because a screen far brighter than the room is a lamp you are staring into. Light behind the screen second: three separate conversations put a lamp or a strip of LEDs behind the monitor to cut the contrast with a dark wall. Distance and angle third: the Academy suggests about an arm’s length with the screen a little below eye level. One genuinely useful pair of glasses exists, from one account: an optometrist can prescribe lenses set for screen distance, which matters most if you are over forty, and the page calls that a prescription, not a product. The colour of the light matters once, at night: the tip that runs through the conversations is to warm the screen after sunset with the built-in night mode, the accounts credit it with easier sleep and fewer evening headaches, and the Academy agrees on the sleep half and goes further, limit screens in the two to three hours before bed. What the warm screen does not do is fix the 3pm ache, and the page’s disagreement is exactly that confusion, with its own decider: a racing mind and poor sleep after evening screens is the filter’s job, dry, aching eyes by mid-afternoon are the break’s and the blink’s, and people who work at screens often have both. One contraindication there is technical: on an OLED phone screen a strongly tinted filter left on for months can leave a permanent shadow on the panel, so use the built-in night mode or a plain dimming there rather than a coloured overlay. On children, three separate conversations carry the finding that time spent outdoors, looking at real distances, is strongly linked to less short-sightedness in developing eyes, which the page calls the one long-term screen concern with weight behind it; the fix is outdoors time, not tinted glasses.

Wear the filtered plugs at anything loud enough to shout over. The earplugs make the band sound better is written by people who put the free plugs in a pocket because they came to hear the music, and a lot of whom now have a sound in their heads that never switches off. Four separate conversations say the surprising part: a loud show is already distorted, the system overdriven and the mix too loud, and a pair of musicians’ earplugs takes the whole thing down evenly so the distortion falls away and you can hear the bass line, the vocal and the hi-hat as separate things again. The plug matters: two conversations and several single accounts say the cheap foam plugs block without control, which is the muffled experience people are afraid of, and what you want is sold as musicians’ or high-fidelity earplugs, a small filter that cuts the volume by a set amount across the range so the balance survives. One correction there: search for the type, not a brand, because one person struck the brand out of their own advice. Why it matters, from six separate conversations and a correction: the parts that hear are tiny hairs deep in the inner ear, and when loud sound bends them past their limit they die and do not grow back; the eardrum heals, the hairs do not. What goes first, three conversations say, are the frequencies that carry speech, so the damage does not feel like the world getting quieter but like people mumbling in a noisy room, and subtitles, and then, three conversations describe, a slow withdrawal from rooms full of people because following them has become work. The part four conversations lead with is that the damage they regret did not come from concerts: across five separate conversations it came from mowing the lawn, power tools, a motorbike, a job site, and across three conversations and two more, from headphones, games played loud to hear footsteps, music turned up to beat the background, a phone volume warning tapped away. The rule from a single account: if you are shouting to be heard where you stand, it is too loud, and more than about fifteen minutes at that level is too long. The numbers the page checked because the conversations did not hold them: the US occupational-health guidance is an average of 85 decibels over an eight-hour day, and every three decibels above that halves the safe time, so a concert or a club at 100 to 110 lets you have minutes, not hours, a loud restaurant sits around the level where a full day is the limit, and a petrol lawnmower is above it. For headphones, two conversations say to find your comfortable level and take it down a notch or two, the ear adjusts within a day, and the World Health Organization’s rule of thumb is about sixty per cent of maximum for no more than sixty minutes at a stretch. Two things that do not protect you, from the cautions: noise-cancelling headphones, which do nothing for the damage your own volume does, and a single gunshot or a smoke alarm at close range. Not having symptoms yet is not evidence you are fine, one account explains, because each unrested exposure spends a little you cannot get back and the ringing only starts once enough is gone. If you already have the ringing, the page’s first distinction is one the people there got wrong and corrected twice: not all ringing is noise damage, wax against the eardrum, an infection, a jaw problem, a stress period and several medicines can all cause it, and those can be temporary and treatable, so the first stop is a doctor, ideally an ear specialist; one caution says that, rarely, ringing in one ear is the first sign of a growth on the hearing nerve. If it is noise damage, six conversations say it does not reverse, and the honest range is wide, from a mild inconvenience to, in their words, a scream in a quiet room, with one caution and one account saying plainly that severe tinnitus has cost lives. What helps, from the people living with it: three separate conversations and a run of single accounts mask it for sleep with a fan, rain sounds, brown noise or a quiet podcast, one caution says keep the masking a little quieter than the ringing, not louder, five single accounts describe the brain learning to file the sound away over months, and one says hunting for the ringing in silence teaches the brain to amplify it. Two lines the page puts first. If your hearing drops suddenly, one ear goes dull, or a loud ringing starts after a gig, a gunshot, a smoke alarm, treat it as urgent and get seen the same day, at an emergency or urgent-care service if that is what is open, because some sudden hearing loss can be treated and the window is short. And do not wear earplugs all the time as a precaution: one account who did, and a correction, describe ears that became painfully sensitive to ordinary sound; plugs are for the loud thing, not for the day.

Turn the captions on for the dialogue. Do not expect them to teach a child to read. What the captions actually fix says that somewhere in the last decade watching with captions went from an accessibility feature to an ordinary habit, and a lot of the people doing it feel vaguely defensive about it. The accounts begin as a confession and end as a chorus: turn them on and you discover how much you were mishearing all along, whole characters’ names and years of lyrics people with perfectly good hearing had wrong. The fixing list is practical: the modern audio mix flattens dialogue under music and effects, and no amount of good hearing recovers a line the mix buried; accents stop being a barrier; the baby stays asleep because the volume can come down; and for people with hearing loss, tinnitus, or the kind of attention that slides off pure audio, the text is an anchor. Then the correction the page exists for. The belief that captions teach a child to read runs right through the accounts, backed by warm anecdotes of early readers who grew up with text on every screen, and the page says the anecdotes are surely true and the arrow is the problem: a six-week randomized trial with primary-school children, published in 2025 and checked for the page in August 2026, found around sixty-six hours of subtitle exposure produced no reading-fluency gain beyond ordinary schooling, and eye-tracking showed why the legend feels true, children who already read well look at subtitles and children still learning mostly do not. Leave the captions on for kids by all means, the page says, the cost is zero and the dialogue benefits are real, but if the goal is literacy the evidenced tool is reading together. For a language, the accounts say subtitles in the language you are learning beat subtitles in your own, which quietly teach you to ignore the audio. The page treats the other camp with respect: some people genuinely watch worse with text on the screen, captions can reveal a punchline a beat before the delivery, spoil an off-screen sound cue by naming it early, and drag your eyes to the bottom of the frame during the exact shot the director composed, comedy suffers most, and one account’s rule is genre-based, captions off for comedies, on for everything dense. On trusting them: captions get shortened, a professional in the accounts says character limits and reading-speed standards force it, and quality varies, so when a line matters, a name, a number, a lyric, treat the caption as a strong hint rather than a court record. Three edges the page keeps: if you are the one listening for a baby, captions plus headphones can quietly remove the very sound you are on duty for, so leave one ear on the room; one deaf account raises a cost nobody else could see, that growing up leaning entirely on text they never developed lip-reading, worth a thought if captions are standing in for a hearing conversation someone should be having with a doctor; and what years of caption-reading do to auditory processing long-term is asked in the accounts and answered nowhere.

Who these pages are not for. The screen page treats no eye condition: if your eyes are consistently red, watery, blurry, painful or sensitive to light, or your vision has changed, that is an optometrist or ophthalmologist and not a habit problem, one person there had strain severe enough to affect their driving; and lubricating drops are for occasional dryness, so needing them every hour is a symptom worth mentioning to a doctor. The earplug page is not a diagnosis; anyone whose hearing dropped suddenly has the same-day line, anyone tempted to wear plugs all day has the accounts who made their ears worse, and its decibel figures are occupational guidance as of 2026, not a personal guarantee, since some people there were damaged by less than others shrugged off. And the caption page says its children’s-reading research was current in August 2026, that science moves, and that if you are reading years later that claim is the one to recheck.
