Eye Test Schedule by Age: Children, Screen Workers and Over-40s
Here’s the routine eye test schedule in one breath: babies get eye checks at birth and in the first months, children get a proper vision test before starting school and then every 1 to 2 years, adults every 2 years, and from 40 the check should include eye pressure, with yearly visits for people with diabetes, a family history of glaucoma, or anyone over about 60. Below is the chart by age, the signs a child can’t see the board, and what a real eye test involves compared with the two-minute machine reading at the optician.
Quick facts
- Newborn to 1 year: red reflex and eye movement checks at birth and at the baby checks
- 3 to 5 years: a proper vision test before school
- School age: every 1 to 2 years, yearly once glasses are prescribed
- Adults 18 to 39: every 2 years if eyes are healthy
- 40 plus: full check with eye pressure, then every 1 to 2 years
- Diabetes: a dilated retina check every year, at any age

Eye test schedule by age at a glance
Treat this as the general pattern. An eye doctor may ask to see you more often if they find something, and that advice wins.
| Age or group | When | What’s checked |
|---|---|---|
| Newborn | At birth, then at early baby checks | Red reflex (cataract, rare tumours), eye shape |
| Babies up to 1 | At routine checks | Following objects, eye alignment (squint) |
| 3 to 5 years | Once, before school | Vision chart with pictures or letters, lazy eye, squint |
| 6 to 17 years | Every 1 to 2 years | Vision, short sight (myopia), glasses power |
| 18 to 39 years | Every 2 years | Vision, glasses power, eye health |
| 40 to 59 years | Baseline at 40, then every 1 to 2 years | Adds eye pressure and optic nerve (glaucoma), near vision |
| 60 plus | Every year | Cataract, glaucoma, macula, glasses |
| Diabetes (any age) | Every year | Dilated retina check |
What age do kids get eye exams, and how often after that?
Babies: the red reflex and squint checks
At birth, a doctor shines a light into each eye to look for the red reflex, the same red glow you see in flash photos. A white or dull reflex can mean a cataract or, rarely, a tumour, and it’s checked again at the early baby visits.
Newborn eyes often wander for the first couple of months. That’s normal. A squint that’s still there after about 3 months, or one that is constant at any age, needs an eye doctor, because the brain can start to ignore the turned eye.
Before school: the test that catches lazy eye
Between 3 and 5 years, every child should have a proper vision test, even if they seem to see fine. Lazy eye (amblyopia) is the reason. One eye sees less clearly, the brain quietly relies on the good eye, and the child never complains because they don’t know any different. It responds best to glasses or patching when caught early, ideally well before 7 or 8.
School-age children: every 1 to 2 years
Short sight usually starts or gets worse during the school years, sometimes quickly. A check every 1 to 2 years suits most children; once a child wears glasses, a yearly check keeps the power right.
Time outdoors in daylight is the habit eye doctors mention most for children’s eyes, often around 2 hours a day, alongside breaks from close-up work and screens.
Signs a child can’t see properly
Children rarely say “I can’t see.” They adapt. Watch for these instead:
- Sitting very close to the TV or holding the phone or book near their face
- Squinting, frowning or tilting the head to look at something
- Covering or closing one eye
- Rubbing their eyes a lot, or watery eyes during homework
- Headaches after school, losing their place while reading, or skipping lines
- Copying wrongly from the board, or the teacher says they seem “not to pay attention”
- An eye that turns in or out, or a white glow in the pupil in photos
Any of these means book an eye test now, not at the next routine date.
Did you know? A child with one weak eye can pass as “fine” for years, because the good eye does all the work.
Adults, screen workers and over-40s
For healthy adults with no eye problems, a check every 2 years is the usual advice. Glasses wearers may go yearly if their power keeps changing.
Long hours on a screen don’t damage the eyes, but they do cause dry, tired, aching eyes and headaches, and an out-of-date prescription makes all of it worse. For the day-to-day part, see our eye care tips for computer users and the 20-20-20 eye break; this page is only about when to get tested.
At 40, get a full baseline check that includes eye pressure and a look at the optic nerve. Glaucoma (kala motia) steals side vision so slowly that most people don’t notice until a lot is lost, and damage can’t be reversed. After that, every 1 to 2 years, and yearly if a parent or sibling has glaucoma, you have diabetes or high BP, or you’re very short-sighted. Near vision also starts to blur in the 40s, which is normal and needs reading glasses, not worry.
From about 60, a yearly check is sensible. Cloudy, glary or dull colours can mean a cataract; our guide to early cataract signs explains what to look for. People with diabetes need a dilated retina check every year from diagnosis, as covered in the yearly diabetic eye check.
What a proper eye test includes (and what a quick machine reading misses)
- History: headaches, screen hours, family glaucoma, diabetes, BP and medicines (steroids matter).
- Vision chart: each eye separately, distance and near.
- Refraction: finding the right lens power; the machine gives a starting estimate, then lenses are fine-tuned by hand.
- Eye pressure: the puff of air or a gentle probe, from 40 or with risk.
- Looking inside: the optic nerve and retina, sometimes with dilating drops that blur vision for 4 to 6 hours, so don’t drive yourself home.
- Extras when needed: a visual field test or scans if glaucoma is suspected.
The two-minute “computer eye test” at a glasses shop is only step 3’s starting estimate. It can’t tell you whether your eyes are healthy. An optometrist does steps 1 to 5; an ophthalmologist (eye specialist doctor) handles disease and surgery.
Myth: eye exercises can replace glasses
No exercise, palming routine or diet changes the shape of the eye, which is what causes short or long sight. Rest breaks help comfort, and they’re worth doing, but they won’t let a child who needs glasses see the board. Skipping glasses doesn’t make eyes “lazy” either; a child who needs them should wear them.
Missed a check? A busy-family version
If the routine date slipped past, just book the next one; nothing is lost for a healthy eye by a few months. Tie eye tests to something you already do each year, such as the new school session in April or August for children and your own birthday month for you. Book the whole family on one visit if the clinic allows it.
Vision drops suddenly in one or both eyes, you see a shower of new floaters, flashes of light or a curtain across your vision, an eye is red and painful with blurred sight, you see haloes round lights with a bad headache and vomiting, or there’s any eye injury. For a chemical splash, rinse with clean running water for at least 15 minutes, then go to emergency. In a baby, a white pupil in photos or a constant squint needs prompt review. Never put surma, kajal or home drops in a child’s eye.

Routine eye test questions, by age
How often should children have eye tests?
Once before school, between 3 and 5 years, then every 1 to 2 years through the school years. Children who wear glasses usually need a yearly check, because their power can change quickly while they grow.
How often should you have an eye test as an adult?
Every 2 years for healthy adults. From 40, the test should include eye pressure, and a yearly check suits people over about 60, anyone with diabetes, and anyone with a family history of glaucoma.
What age can children have their first eye test?
Babies are checked from birth, and an eye doctor can examine a child at any age if there’s a worry. A full vision chart test usually works from about 3, using pictures instead of letters.
Is an eye test every 2 years enough?
For healthy adults under 40 with stable vision, yes. It isn’t enough with diabetes, glaucoma in the family, fast-changing glasses, or over 60; those need yearly checks or whatever the eye doctor advises.
How often should an eye test be done over 70?
Once a year is the usual advice, sooner if vision changes. Cataract, glaucoma and macular problems become more common with age, and good sight also lowers the risk of falls.
Can a child’s eyesight be checked at home?
You can notice warning signs at home, such as squinting, sitting close to the TV or covering one eye. Printed or online charts can’t replace a proper test, because they miss lazy eye, squint and eye health problems.
Do screens make children short-sighted?
Lots of close-up work and too little time outdoors are both linked to short sight in children. Breaks from screens and books, plus daily outdoor play, are the usual advice, along with regular eye tests.
Does a diabetic need an eye test every year?
Yes. A dilated retina check every year is the standard advice from diagnosis, because diabetic eye damage causes no symptoms early and treatment works best before vision is affected.
Is the computer eye test at an optician enough?
No. The machine only estimates your lens power. A full test also checks each eye’s vision, eye pressure and the health of the retina and optic nerve.
Will wearing glasses make my child’s eyes weaker?
No, that’s a common worry without basis. Glasses let the child see clearly, and for lazy eye they’re part of the fix. Power may still change as the child grows, which is why yearly checks matter.
Do I need an eye test for a driving licence?
Licensing offices usually do a basic vision check, but it isn’t a full eye test. If you struggle to read signs, especially at night, get a proper test before you drive.
