Visual acuity test
You want to know how well each eye sees: for yourself, before buying glasses, or to compare with last year.
What’s included: visual acuity of the right and left eye on a letter chart, each eye separately.
Each eye separately · with and without glasses
1,500 ₸ per test — and you get a number for each eye. If the number has dropped, we’ll tell you honestly when a full eye exam is needed.

Line 1 of 8
Hold your phone at arm’s lengthSit an arm’s length from the screen and cover your left eye with your palm without pressing. The letters will get smaller until they start to blur.
Which letter is underlined?
This isn’t a diagnosis: a phone screen can’t replace the chart at the clinic. There you have 5 metres, even lighting and each eye tested separately.
Visus, OD, OS — in plain words
Visual acuity is how small a detail your eye can make out from a distance. The test measures it in each eye separately. Normal is 1.0: from five metres you read the tenth line of the chart. Think of a camera lens: at 1.0 the photo is sharp, at 0.5 small print is already blurred.
In the doctor’s notes, acuity is written separately: OD — right eye, OS — left. That’s why one eye is covered during the test. With both eyes open, the stronger eye hides the weaker one, and people go for years without knowing one eye sees worse.
The first number is recorded without correction, the second with lenses. If acuity improves with lenses — it’s the eye’s optics, and glasses, contact lenses or laser can fix that. If it doesn’t — the cause is looked for in the eye itself.
Some people see better than normal. It’s an individual trait, not a reason for pride or worry. What matters more is how your number changes from year to year. If it drops by a couple of lines — that’s your reason to come in.
Honestly, before you book
The chart checks sharpness in the centre. Eye diseases often start somewhere else. Glaucoma, for example, leaves central vision alone for a long time: first it eats away at the edges of the visual field, while the person still reads the tenth line with ease. It’s like checking a car by how brightly the headlights shine: the lights are fine, but you’ve learned nothing about the brakes.
You can’t feel it or see it on a chart. At the full eye exam, pressure is measured by a device without touching the eye — with a puff of air.
The doctor examines the retina and optic nerve through a dilated pupil. Letters won’t tell you anything here.
The chart is straight in front of you. What happens at the sides is checked with another test — perimetry.
Prices from the clinic’s price list
The acuity test answers “how well do I see?”. The full eye exam answers “why?”. The first costs about as much as a cup of coffee and gives you a number for each eye. The second is one visit, after which the doctor explains what’s going on with your eyes and what to do about it.

No drops, no touching
You sit and read letters — that’s all you need to do. Pupils aren’t dilated, so you can drive straight after the test. Adults and schoolchildren manage it equally well.
Walk through the clinic — 8 rooms in a minuteStarting with diagnostics
With an occluder, one at a time. That way the stronger eye can’t help the weaker one, and each gets its own number.

Line by line, from large to small. The last line you read confidently — that’s your number: 0.6, 0.8, 1.0.

If the number is below normal, lenses are placed in front of your eye. If it goes up — glasses, contact lenses or laser can correct your vision. If not — that’s a reason for a full eye exam.
Sound familiar?
Vision declines so slowly that your eye has time to adapt. People don’t notice the number, they notice the little things around it. Here’s what most often brings people in for an eye test.

If it’s for a child
A child won’t say “I can’t see well” — they have nothing to compare with. They just move closer. A device you look into like a little window works even with toddlers, and a paediatric ophthalmologist explains the result to you, the parent.

A number without an explanation is only half the job. If your acuity has dropped or one eye sees worse than the other, an ophthalmologist will find the cause at the full eye exam and tell you what to do about it. These three doctors carry out full eye exams at the clinic’s listed prices.

Ophthalmologist, full eye exams

Questions
The visual acuity test is 1,500 ₸ per test: acuity of the right and left eye. A full eye exam with eye pressure, the back of the eye and a talk with the doctor is 20,000 ₸ per visit; a follow-up visit is 13,000 ₸ per visit.
Not necessarily. Acuity shows sharpness in the centre of your visual field. The chart doesn’t check eye pressure, the retina, the optic nerve or the edges of the visual field. Glaucoma, for example, leaves central acuity unchanged for a long time. So once a year, after 40 or if glaucoma runs in your family, it’s worth having a full eye exam.
The acuity test tells you how well each eye sees. The full eye exam tells you why: on top of acuity it adds autorefraction, no-touch eye pressure, the drainage angle and back of the eye with dilated pupils, lens selection, a slit lamp exam and a talk with the doctor.
You can get a rough idea, but not a measurement. Letter size on screen depends on the phone and the distance, so we count lines, not acuity. This isn’t a diagnosis. The exact number comes from the chart at the clinic: five metres, even lighting and each eye separately.
No preparation is needed. Pupils aren’t dilated for the acuity test, so you can drive straight away. If you wear glasses, bring them: acuity is checked both with and without them.
OD is the right eye, OS the left. Acuity is recorded for each eye separately: first without correction, then with correction. If the number goes up with lenses, it’s the eye’s optics; if not — the cause is looked for deeper.
Yes. For a schoolchild who moves closer to the board or the TV, it’s best to start with a paediatric ophthalmologist: the doctor checks more than acuity and explains the result to the parent.
