What is myopia?
If you struggle to recognise faces across the street, frequently squint, or see clearly up close but not at distance, you may have myopia (short-sightedness) — a very common focusing error, not a disease.
Searching for "I can't see far away", "short-sightedness", or "near-sightedness"? Those usually mean the same thing as myopia — explained below.
I can't see far away — is that myopia?
Yes, usually. If distance blurs — road signs, TV, faces across a room — but your phone and book stay sharp, that is classic short-sightedness (myopia). Only an eye test confirms it.
Myopia means your eye focuses light in front of the retina instead of directly on it. Distant objects blur; near objects stay clear. It is usually caused by the eyeball being slightly too long or the cornea being a little too curved.
Dedicated symptom guide: Can't see far away — checklist, when distance blur is not myopia, and treatment paths.
It is not an infection and it does not mean your eyes are "damaged" in the everyday sense — but uncorrected myopia affects driving, sport, work, and confidence. Glasses and contacts manage it daily; LASIK, SMILE Pro, and ICL can correct it permanently when clinically suitable.
Short-sightedness vs long-sightedness: myopia blurs distance and keeps near clear. Hyperopia (long-sightedness) is often the opposite pattern — see our related guides if both distances feel off.
Symptoms of myopia
The classic pattern is blurry distance, clear near — road signs and faces across a room blur, but your phone and book stay sharp without glasses.
People also ask
- Why can't I see far away? Distance blur with clear near vision is the defining sign of myopia (short-sightedness). Your eye focuses far objects in front of the retina. Glasses, contacts, or surgery correct it after an eye test.
- Why can't I read road signs? Same reason — distance blur. Signs, number plates, and cinema screens look fuzzy until you move closer or put glasses on.
- My phone is clear but the TV is blurry — why? Classic myopia: near vision works, distance does not. The eye focuses close objects correctly but not far ones. Book an eye test to confirm.
- Is short-sightedness the same as myopia? Yes — myopia, short-sightedness, and near-sightedness are the same condition. Myopia is the clinical name; short-sightedness is what most people say.
- My vision suddenly became blurry — is that normal? A rapid change can mean your prescription shifted (common in teens and twenties) or another eye issue. Book an eye test within a few weeks; sudden one-eye blur with flashes needs urgent care.
- Why do I get headaches after driving? Squinting and straining to focus at distance causes eye fatigue and frontal headaches — especially at night when contrast is low.
Blurred distance vision
Mild myopia (−1 D) may blur from ~1 m; high myopia (−6 D+) can blur almost everything beyond arm's length without correction.
Squinting without realising
Squinting pinholes light into the eye and temporarily sharpens the image — a habit opticians look for in school-age eye tests.
Night driving difficulty
Low contrast makes distance blur worse. Driving and many sports rely on clear distance vision — myopes often struggle without correction.
Sport and outdoor frustration
Ball sports, swimming, and skiing suffer when distance judgement is poor or correction is unstable — a common reason people seek permanent correction.
How do I know if I have myopia?
You likely have myopia if distant objects blur while reading stays clear, and your prescription shows a negative Sph number (e.g. −2.50). Only an eye examination confirms it.
Self-check is not a diagnosis — but these patterns strongly suggest myopia:
- 1You sit closer to the TV or move your phone nearer than others need to.
- 2You pass a number-plate test only when you know where to stand, or not at all without glasses.
- 3Your last prescription shows minus sphere (Sph) — the higher the number, the stronger the myopia.
- 4Your glasses prescription has increased every year — common in teens; should stabilise by your early twenties.
Sound familiar?
- My glasses are getting stronger every year Normal during growth years. Surgery waits until the prescription is stable for at least 12 months — usually by your early twenties.

What causes myopia?
Myopia is mainly caused by the eyeball growing slightly too long during childhood, driven by genetics and too little outdoor time — not by reading in dim light or "using screens too much" alone.
One myopic parent gives roughly a 1-in-3 chance of myopia; two myopic parents, about 1-in-2. Environmental factors — especially less daylight during eye development — accelerate progression. Sustained near work adds to the picture when combined with limited outdoor time.
Wearing glasses does not make myopia worse. Not wearing them does not strengthen your eyes. These are persistent myths.
Myopia risk factors
Higher risk if you have myopic parents, spent little time outdoors as a child, do long hours of close work, or developed myopia before age 10.
Higher progression risk
- Both parents myopic
- Onset before age 8
- Less than 1 hour outdoors daily in childhood
- East Asian ethnicity (higher population rates)
Lower progression risk
- Stable prescription 12+ months (adults)
- Regular outdoor time in childhood
- Moderate prescription (−3 D or below)
How is myopia diagnosed?
Myopia is diagnosed through a comprehensive eye examination that measures how clearly you see distant objects — usually refraction, visual acuity, and often retinal checks for higher prescriptions.
Your optometrist or ophthalmologist will:
- 1Test distance vision (reading letters or numbers on a chart).
- 2Perform refraction to find your prescription (Sph, Cyl, Axis).
- 3Check eye health — especially retina if you are high myopia (−6 D+).
- 4If you later consider surgery, additional scans (Pentacam, corneal thickness) map suitability for laser vs implant.
You can request a written copy of your prescription from your optician or eye care provider — keep it for future consultations.
Can myopia be prevented?
No — you cannot fully prevent myopia if you are genetically predisposed. More outdoor time in childhood and regular breaks from near work may slow progression, not eliminate it.
Myopia control strategies (specialist contact lenses, atropine drops) exist for progressing children — not for adults seeking permanent correction. Once stable, the practical options are glasses, contacts, or refractive surgery.
Can children develop myopia?
Yes — myopia usually begins between ages 6 and 14, progresses through the teenage years, and typically stabilises in the early twenties. Early onset (before age 8) often means faster progression and higher final prescription.
Warning signs in children: sitting close to the TV, squinting at the board, falling behind in sport, or frequent prescription changes at optician visits. A comprehensive eye test — not just a school screening — confirms myopia and tracks progression. Myopia control (ortho-k lenses, atropine drops, specialist soft lenses) may slow progression in actively worsening children; these are managed by a paediatric or specialist optometrist, not replaced by adult laser surgery.
Parents often ask whether surgery is an option for teenagers — refractive surgery is generally deferred until 21+ with a stable prescription for at least 12 months. Read our full guide on when myopia stabilises.
Does screen time cause myopia?
Screen time alone does not cause myopia — but long hours of near work combined with too little outdoor daylight during childhood accelerates progression in genetically predisposed eyes.
Research points to outdoor light — not distance viewing itself — as the protective factor. Two hours of daily outdoor time in childhood is associated with lower myopia risk and slower progression. Screens are part of modern near work; the practical advice is balance: regular breaks (20-20-20 rule), outdoor time, and annual eye tests for children with myopic parents. Reading in dim light does not cause myopia — this remains a common myth.
Can myopia get worse? Is it dangerous?
Myopia often progresses in childhood and teens, then usually stabilises in your early twenties. Moderate myopia is not dangerous day-to-day; high myopia (−6 D+) needs annual retinal monitoring.
For most adults, myopia is a stable inconvenience — not a medical emergency. The main "danger" is practical: driving uncorrected, or missing retinal changes in very high myopia. Prescriptions above −6 D carry a modestly higher risk of retinal thinning and detachment — reason for yearly dilated exams, not panic.
How fast does myopia progress?
In children, myopia often increases by 0.5–1.0 D per year during puberty. Most people stabilise by 21–25; surgery requires stability for at least 12 months.
If your prescription is still changing every 6 months as an adult, wait before surgery — correcting a moving target leads to regression. High myopes occasionally progress into the late twenties; surgeons delay until stability is proven. Read: Can myopia return after LASIK?
Myopia progression in adults
Most adults have stable myopia by their mid-twenties. Progression after 25 is uncommon but not impossible — especially with high myopia, pregnancy, or undiagnosed eye disease.
If your distance prescription keeps increasing as an adult, do not assume laser surgery will fix a moving target. An ophthalmologist should rule out keratoconus, cataract onset, or blood-sugar-related shifts before any refractive procedure. Stable myopia for 12+ months is the standard prerequisite for LASIK, SMILE Pro, or ICL.
Understanding your myopia prescription
Look at the Sph column on your prescription: negative numbers (e.g. −3.50) mean myopia. The larger the minus, the blurrier distance vision without glasses.
| Sph value | Level | Day-to-day | Typical treatment |
|---|---|---|---|
| −0.5 to −3.0 D | Mild | Blur beyond 1–3 m; may cope indoors without glasses | LASIK · SMILE Pro |
| −3.0 to −6.0 D | Moderate | Full-time glasses or contacts for distance | LASIK · SMILE · ICL |
| −6.0 to −10.0 D | High | Essential correction at all times | Laser if cornea thick enough; ICL often preferred |
| Above −10.0 D | Severe | Extreme distance blur; retinal monitoring | ICL up to −20 D |
Also have astigmatism (Cyl on your prescription)? It is treated in the same procedure as myopia — see our astigmatism guide.
Best treatment for high myopia
For high myopia (−6 D to −10 D), LASIK or SMILE Pro may suit if corneal thickness allows. Above roughly −8 to −10 D, or with thin corneas, ICL is often the safer primary choice — correcting up to −20 D without removing corneal tissue.
High myopia also needs retinal health monitoring before and after any procedure. The best treatment is not the same for every high myope — it depends on prescription, corneal mapping (Pentacam), anterior chamber depth, and age.

Glasses manage myopia — surgery can correct it.
Compare everyday management with permanent options from −0.5 D to −20 D, including when each approach makes sense.
Treatment options for myopia
Glasses and contacts manage myopia daily. LASIK, SMILE Pro, and ICL permanently correct vision by reshaping the cornea or placing a lens inside the eye — when clinically suitable.
Laser · flap
LASIK
Corneal flap + excimer laser. Default choice for stable prescriptions with adequate corneal thickness.
Learn about LASIK → Laser · flaplessSMILE Pro
No corneal flap — lower dry-eye risk and contact-sport friendly within platform range.
Learn about SMILE Pro → Surface laserPRK
No flap — suitable when corneal thickness is borderline or surface treatment is preferred.
Learn about PRK → Implant · high myopiaICL
Lens placed inside the eye — no corneal tissue removed. Reversible and ideal for high prescriptions.

Browse eye conditions →Can LASIK fix myopia?
Yes — LASIK permanently corrects myopia up to roughly −10 D in suitable candidates by flattening the cornea so light focuses on the retina. It does not "cure" the longer eyeball, but you see clearly without glasses.
LASIK also treats myopia with astigmatism in one session. For severe or high myopia, eligibility depends on corneal thickness — not prescription alone. Read our detailed guides: Can LASIK fix severe myopia? · How much myopia can LASIK correct? Compare options in LASIK vs SMILE and LASIK vs ICL.
Who is not suitable for myopia surgery?
Surgery is not suitable if your prescription is still changing, you are under 21, pregnant, have uncontrolled glaucoma, keratoconus, or corneas too thin for safe laser treatment.
Usually not suitable now
- Under 21 or unstable prescription (<12 months)
- Pregnant or breastfeeding
- Keratoconus or progressive corneal disease
- Cornea too thin for safe LASIK/SMILE ablation
- Uncontrolled diabetes or glaucoma
- Prescription above −10 D for laser (ICL may still suit)
Often suitable if
- Age 21–55, stable 12+ months
- Healthy cornea on Pentacam mapping
- Realistic expectations (distance vision; reading glasses after 45 possible)
- No active eye infection or severe dry eye

Recovery after myopia treatment
LASIK/SMILE: most patients see clearly within 24–48 hours and return to desk work in 1–2 days. ICL: clearer vision over 2–5 days; full stabilisation within weeks.
For patients who choose to travel for surgery, a typical recovery timeline looks like this:
Day 0
Pre-op scans + procedure (15–20 min both eyes). Rest at hotel same day.
Day 1
Post-op check. Most LASIK/SMILE patients cleared to fly home.
Week 1
Video follow-up with Istanbul surgeon. Avoid swimming and eye rub.
Month 1–3
Vision stabilises. Final check before resuming contact sport (surgeon confirms).
How much does myopia treatment cost?
There is no fixed price. Cost depends on your prescription, whether LASIK, SMILE Pro, PRK, or ICL is suitable, and what your package includes — we provide a personalised quote after reviewing your profile.
Surgery pricing varies from person to person. Two patients with different prescriptions, corneal measurements, or astigmatism levels may need different procedures — and different aftercare plans.
Procedure type
Laser (LASIK, SMILE Pro, PRK) and implant surgery (ICL) are priced differently because the technology and theatre time differ.
Prescription strength
Higher myopia may require ICL instead of laser — or additional pre-operative scans and retinal checks.
Astigmatism
Toric corrections (for cylinder on your prescription) can affect lens choice and surgical planning.
Package inclusions
Hospital fees, post-op medication, follow-up checks, accommodation, and transfers may all form part of an all-inclusive quote.
