Blurry vision — what's causing yours?

Distance blur, near blur, ghosting, or sudden vision loss — the pattern points to different conditions. Match your symptoms honestly before choosing laser, lens surgery, or an eye test.

Match your blur pattern

Where and when vision blurs is the fastest clue to the underlying cause. Refractive errors (myopia, hyperopia, astigmatism) are treatable with laser or lens surgery when clinically suitable — but cataracts, keratoconus, and sudden vision loss need different pathways. Only an eye test confirms your diagnosis.

What you notice Likely cause Typical age Guide
Distance blurry, near clear — road signs, TV, faces across a room Myopia (short-sightedness) Any age; often teens–30s Can't see far guide · Myopia · LASIK
Near blurry, distance OK — reading, phone, menus (especially after 40) Presbyopia or hyperopia 45+ (presbyopia) · any age (hyperopia) Can't read small text · Presbyopia · RLE
Blurry at all distances — ghosting, streaks around lights Astigmatism Any age; often with myopia Astigmatism guide · LASIK for Cyl
Progressive blur — new glasses help briefly, then fail again Keratoconus (screen first) Teens–30s KC guide · Pentacam
Dull colours, glare at night, frequent prescription changes Cataracts Usually 55+ Cataracts · Surgery
Vision clears after blinking, then blurs again — gritty eyes Dry eye (often post-LASIK or contact lenses) Any age Dry eye guide
Sudden blur in one eye, flashes, curtain shadow, severe pain Medical emergency — not refractive surgery Any age Seek urgent same-day eye care

Common questions

Blurry vision — FAQ

Direct answers before you book an eye test or eligibility check.

Blurry vision usually means light is not focusing sharply on the retina. Common refractive causes are myopia (distance blur), hyperopia and presbyopia (near blur), and astigmatism (blur at all distances). Cataracts, dry eye, and keratoconus also blur vision — pattern and age help distinguish them. Only an eye test confirms the cause.
Distance blur with clear near vision is classic myopia — but astigmatism, early cataracts, and dry eye can mimic it. If your phone is sharp but road signs blur, myopia is likely; book an eye test to measure your −Sph.
One-eye blur may be a simple prescription difference, contact lens issue, or early cataract in that eye. Sudden one-eye blur with flashes, floaters, or a shadow across vision needs urgent same-day assessment — not refractive surgery planning.
Seek urgent care the same day for sudden painless vision loss, curtain or shadow across vision, new flashes with floaters, severe eye pain with blur, or chemical injury. These are not LASIK candidates until the acute cause is treated.
LASIK permanently corrects blurry vision from myopia, hyperopia, and astigmatism when your prescription is stable 12+ months and corneal mapping is suitable. It does not treat cataracts, keratoconus, or presbyopia as a standalone fix — those need lens surgery or other pathways.
Reading blur after 40–45 is usually presbyopia — the natural lens stiffens. Distance may stay acceptable. Reading glasses or lens replacement with a trifocal IOL address it; standard distance LASIK alone does not restore full near vision.
