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

Six pages in this library are about eyes and ears. Three of them say 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 those three put a line first that is not about habit at all. The other three are about the eye itself: Rinse the eye with water and do not rub it is for something in it, Put the drop in the pocket under your lower eyelid is for getting a drop in, and Check your child’s photos for a white glow in the eye is for a pupil that looks white in a photo. All three put their safety lines first.

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. Some people 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 what people said 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 people 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 people that found relief in them were usually also doing the things that work. Brightness first: some people 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: some people 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 person: 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 what people said is to warm the screen after sunset with the built-in night mode, people 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 what decides it: 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 caution 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, some people 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. Some people 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: some people 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 many people 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, some people 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, some people describe, a slow withdrawal from rooms full of people because following them has become work. The part some people lead with is that the damage they regret did not come from concerts: many people say it came from mowing the lawn, power tools, a motorbike, a job site, and some people say 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 one person: 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 people there did not give 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, some people 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 person 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 person warns that, rarely, ringing in one ear is the first sign of a growth on the hearing nerve. If it is noise damage, many people 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 the page and one person saying plainly that severe tinnitus has cost lives. What helps, from the people living with it: many people mask it for sleep with a fan, rain sounds, brown noise or a quiet podcast, one person warns: keep the masking a little quieter than the ringing, not louder, many people 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 person 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. People 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 people, 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, people 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 person’s rule is genre-based, captions off for comedies, on for everything dense. On trusting them: captions get shortened, a professional among people 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 person 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 among people and answered nowhere.

If something gets into your eye, do not rub it: rinse it with plenty of clean water. Rinse the eye with water and do not rub it puts an emergency box first, and it comes first here. If a strong chemical such as oven cleaner or bleach is in your eye, if a sharp object has pierced it, or if something hit it at high speed, this is an emergency: in the US call 911 or go to the emergency room; in the UK call 999 or go to A&E; elsewhere use your local emergency number. Do not drive yourself, the NHS says: ask someone to drive you or call an ambulance. Start rinsing at once and keep rinsing while you wait. The NHS says to run lots of clean water, not hot, over the eyeball for at least 20 minutes, with the flow not too strong; MedlinePlus, the US government’s health information service, says a gentle stream of cool tap water for 15 minutes for a chemical splash, then seek medical help right away. If you are unsure which to follow, keep going. The NHS says not to try to remove an object that has pierced the eye, and to take the container of the chemical with you. In the US, the Poison Help line, 1-800-222-1222, is free, open every day around the clock, and will advise on a chemical; do not let a phone call delay the rinsing. The NHS also says to get urgent care for severe pain, any change in your sight, an eye you cannot keep open, or blood or pus coming from the eye. In the UK, for something less urgent, NHS 111 can advise.

Why not rub: some people say rubbing an irritated eye can scratch the cornea or push an object deeper, the NHS says not to touch or rub your eye until it is better, and MedlinePlus says not to rub the eye or squeeze the eyelids when something is in it. Many people say flushing with water is the main safe way to get something out, and the health services say the same. People differ on a bowl against running water, and what decides it, they say, is whether it is grit or a chemical; for a chemical, the health services describe running water. Where there is no tap, the NHS says bottled water will do. Plain water is what the NHS, MedlinePlus and the US Centers for Disease Control name, and MedlinePlus also names saline solution. One person warns that undissolved salt in a homemade rinse can scratch the cornea and cause permanent vision loss. For a bit of grit or an eyelash, MedlinePlus says to examine the eye in good light without pressing on it and to try gently rinsing with clean water, and not to use cotton swabs, tweezers or anything else on the coloured part of the eye; one person warns that if rinsing does not get the object out, you should not ask others to take it out by hand, and should go to the emergency room. For pepper spray or tear gas, the CDC says to leave the area and get fresh air, and if your eyes are burning or your vision is blurred, to rinse with plain water for 10 to 15 minutes; to take contact lenses out and not put them back in; to wash the spray off your skin with lots of soap and water, put your clothes in a sealed plastic bag, and get medical care as quickly as you can, dialling 911 and explaining what has happened. On contact lenses after a chemical splash or spray, the page says the NHS and the CDC lines are the ones to follow, and to take them out if you can do it without delay; the sources differ on contact lenses in other cases, and the page gives each.

The drop page is the quiet half. Put the drop in the pocket under your lower eyelid is about drops going into an eye that is otherwise well, and it sends anyone with something in the eye back to the rinse above. The American Academy of Ophthalmology and a Moorfields Eye Hospital patient leaflet give the same method: wash your hands, tilt your head back and look up, pull the lower lid down away from the eye to form a pocket, and hold the tip over the pocket without touching the bottle to your eye, lid or skin. Moorfields adds that one drop is usually what the clinician advises, and to use only the number of drops you were told. Then close your eye gently; one person warns that squeezing your eyes shut as you squirt can push the liquid out down your cheek. Both then say to press the inner corner of the eye, where the tear duct is: Moorfields says for 30 to 60 seconds, the Academy for a minute or two. With more than one kind of drop, the Academy says to wait 3 to 5 minutes between them, and Moorfields says to leave five. If you flinch, the Academy says you can keep your eyes closed, put the drops in the corner near your nose and blink to roll them in, or ask someone to help; one person warns that a drop on a closed eye or on the skin nearby invites infection from bacteria on the skin and lids, and says to pull the lower lid down instead, while another says the risk is small and that they have done it for years without trouble. Moorfields says that if you think the drop missed, you can safely try again straight away. The Academy says to take contact lenses out before putting in drops, unless your ophthalmologist has told you to leave them in. Which drops to use, how many and for how long is for the person who prescribed or sold them. If your drops were prescribed and you cannot get them in at all, do not simply stop: ask your pharmacist or eye clinic, because Moorfields says aids and alternative bottles are often available.

If a photo, or dim light, shows a white glow in the middle of your child’s pupil, ask for an urgent eye examination and do not wait for the next routine check. Check your child’s photos for a white glow in the eye puts its safety line first. A white glow in the middle of your child’s pupil, a swollen or painful eye, uncontrolled eye movements or signs that your child cannot see well are reasons to get help now. In the UK, the NHS says to ask for an urgent GP or optician’s appointment or call NHS 111; in the US, call your child’s doctor today and ask for an urgent eye examination. If your child is seriously unwell, call 999 in the UK or 911 in the US. Photos are one way to notice a problem, not a test: the NHS lists other signs too, including a squint and a change in the colour of the coloured part of the eye, and a clear photo does not rule them out. The NHS describes the sign as a white glow or white reflection in the centre of the eye, the pupil, which you may notice in low light or in photos taken with a flash, and the American Academy of Ophthalmology puts it the same way: when light shines in the eye, as with a flash, a pupil that is usually dark can look white. It names the eye cancer behind the warning, retinoblastoma, which the NHS describes as rare, and it is written for babies and young children, since the National Cancer Institute says it occurs most often in children younger than 2, though it can occur at any age. Some people say a white pupil does not always mean cancer and can be a cataract or another cause, but that it is never a good sign and needs a professional look either way; the page cannot tell a harmless cause from a serious one by looking at a photo, and the examination does that. The reason to act quickly is what the NHS says about the outcome: retinoblastoma can usually be treated successfully if found early, and there is a high chance of losing some or all of the sight in the affected eye. In the UK, the NHS says that if your child is referred to a specialist, the appointment should happen within 2 weeks. In the United States, the American Academy of Ophthalmology says to call your child’s doctor right away if you notice anything unusual about your child’s eyes, and the American Association for Pediatric Ophthalmology and Strabismus says a child with a white pupil should see an eye doctor right away. So in the US, call your child’s doctor today, say what you saw and ask for an urgent eye examination. One person pointed out that the right specialist is an ophthalmologist, a medical doctor, rather than an optometrist. The page does not cover cost or insurance, so ask about both when you book. If you have seen a white glow and are told it is nothing, the NHS still lists it as a reason for urgent help, so it is fair to ask whether an eye specialist should see your child. One person says some phones remove red-eye from photos automatically, which can hide a white pupil, and that you can turn that feature off or look at the eye when the camera’s focus light comes on; the NHS says you may also notice it in low light, so a flash photo is not the only way to see it. In the UK, the NHS says a baby’s eyes are looked at in the newborn physical examination, within 72 hours of birth and again at 6 to 8 weeks, and one person pointed out that a routine check should catch a white pupil but can miss it, saying a pediatrician missed it at six months in their case, so looking at your own photos is an extra, not a replacement for those checks. Some people dismissed the warning as fear-mongering, and others defended it, citing cases where finding it early made the difference; the NHS, the National Cancer Institute and the American Academy of Ophthalmology each list a white pupil among the signs, so it is not a hoax, and nor is it a reason to feel alarmed about every photo. The page cannot diagnose anything. If your child is seriously unwell, or an eye is swollen or painful, or they seem unable to see, do not look through photos first: your child’s doctor or NHS 111 for an eye problem, and 911 or 999 if your child is seriously unwell. If your child already has an eye diagnosis, your child’s treatment team is the place to ask. It is about your own child’s photos; an adult with a changed eye, or a child with some other eye complaint, should see their own doctor or an optician.

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 people 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.
