High myopia (very short-sighted)
Myopia (near-sightedness) makes distant objects look blurry while near vision stays sharp — the most common refractive error, and easily corrected.
Beyond thick glasses
Being very short-sighted (high myopia) means distance is blurry without correction — but the eye is also stretched, which raises the long-term chance of earlier cataract, changes at the macula and glaucoma. Regular dilated exams matter even when glasses work fine. Step through the picture below.
Overview
In myopia the eye is slightly too long (or the cornea too steeply curved), so light from distant objects focuses just in front of the retina instead of on it. The result: street signs, whiteboards and faces across a room look soft, while reading and close work stay clear. Myopia usually appears in childhood and can progress through the teens. It is corrected with glasses, contact lenses or laser surgery — and in children, its progression can often be slowed.
Symptoms of myopia
- Blurry distance vision — signs, screens and faces across a room look soft
- Squinting or partly closing the eyes to see far away
- Sitting close to the TV or the front of the classroom
- Headaches or eye strain from squinting
- Trouble seeing while driving, especially at night
What causes myopia
- The eyeball is slightly too long, or the cornea too steeply curved, so distant images focus in front of the retina
- A strong genetic component — myopia runs in families
- A lot of close work and limited time outdoors in childhood are linked to its onset and progression
Myopia risk factors
- One or both parents with myopia
- Extensive near work and little time outdoors in childhood
- Childhood onset (it tends to progress through the teens)
Prevention & early detection
- Myopia can't be prevented, but a child's progression can often be slowed — more time outdoors plus myopia-control options (special contact lenses or glasses, or low-dose atropine drops)
- Regular eye exams keep the prescription current and catch progression early
Treatment
Glasses and contact lenses correct myopia simply. Laser vision correction (LASIK, PRK, SMILE) reshapes the cornea for suitable adults with a stable prescription, and lens-based options exist too. For children, myopia-control treatments slow how fast it worsens. An eye exam determines the right prescription and approach.
When to see an eye doctor
Distance blur that improves with glasses is routine — book an eye exam, and a child squinting or sitting close to screens should be checked. See an eye doctor promptly for sudden blur, blur in one eye, or blur with flashes, floaters or pain, which suggest something other than simple myopia.
Seek urgent care for:
- Sudden blurring, especially in one eye
- Blur with flashes, new floaters or eye pain
- A child squinting, head-tilting or sitting very close to screens
Frequently asked questions
What does myopia look like?
Near objects stay sharp while distant ones blur — street signs, screens across a room and faces at a distance look soft, and squinting briefly sharpens them. The simulator's Near / Medium / Far scene shows distance blurring while near stays clear.
Can myopia be cured?
It isn't 'cured', but it's fully corrected with glasses, contacts or laser surgery. In children, myopia-control treatments can slow how quickly it progresses.
Why is my child's myopia getting worse?
Childhood myopia commonly progresses through the teens as the eye grows. More time outdoors and myopia-control options (special lenses or low-dose atropine) can slow it — ask your eye doctor.
Is myopia the same as astigmatism?
No. Myopia blurs distance because the eye is too long; astigmatism blurs or doubles vision at all distances because the cornea is unevenly curved. They often occur together, and both are corrected with glasses.
