Myopia is a refractive error: the eyeball grows slightly too long, or the cornea curves too steeply, so light focuses just in front of the retina instead of on it. Distance vision blurs; near vision usually stays clear.
It is not a disease of the eye and it is not caused by reading in dim light. It cannot be reversed by exercises or drops — but it can be corrected, and in children its progression can be slowed.

Adults usually notice it themselves. Children almost never do — they assume the world looks this way for everyone, so parents and teachers are often the first to spot it.
Distant boards, road signs and number plates look blurred while your phone stays sharp.
You narrow your eyes to make far-away things clearer.
Headaches or aching eyes after driving, meetings or a long day of screens.
Night driving feels harder — headlights glare and edges lose definition.
You need to sit closer to the television than others in the room.
Your glasses or lens power has changed more than once in recent years.
Any one of these is worth an eye check.
Sitting very close to the television, or holding books and tablets close to the face.
Screwing up the eyes or tilting the head to look at the board.
Copying from the blackboard has become slow, or marks have quietly dropped.
Frequent eye rubbing, blinking or complaints of headache after school.
Losing interest in outdoor games and sport that need distance vision.
Sitting at the front of the class to see, or asking friends what is written.
Clear vision depends on light landing exactly on the retina. In a myopic eye the eyeball is slightly too long from front to back, or the cornea is curved too steeply — either way, light comes to a focus just short of the retina and distance images blur.
Most myopia begins in childhood, between roughly six and fourteen years, as the eye grows. It typically increases through the growing years and settles in the late teens or early twenties.
Genetics matter most — a child with one myopic parent is at higher risk, and with both parents higher still. Environment then shapes how fast it progresses.
Family history — the strongest single factor; risk rises with one myopic parent and rises further with two.
Age — onset is most common between six and fourteen, and progression tracks the growing years.
Prolonged near work — long hours of reading, study and screens without breaks are linked to faster progression.
Little time outdoors — children who spend less time in daylight are at higher risk — outdoor time appears protective.
Urban living and schooling pressure — both are associated with the rising rates of childhood myopia seen across India and Asia.
Myopia is measured in dioptres (D) — the minus number on your prescription. The grade guides both which treatments suit you and how closely your retina needs watching.
Usually corrected easily with glasses, contact lenses, Ortho-K or laser vision correction. Retinal risk is close to that of a normal eye.
Most correction options still apply. Regular checks matter, and corneal thickness decides whether laser or an ICL is the safer route.
Correction is very possible, often with an ICL. The priority alongside vision is lifelong retinal monitoring, because the eye is stretched.
A small proportion of very high myopia keeps progressing into adulthood and stretches the retina and choroid enough to affect vision permanently. It needs long-term retinal monitoring rather than correction alone — our OCT imaging and dilated retinal examination are used to track it.
Confirming myopia takes minutes; deciding what to do about it takes a full workup. A comprehensive examination measures not just your number but the shape, thickness and length of your eye — the details that determine which treatments are safe for you.
In children we use cycloplegic refraction — drops that relax the focusing muscle — because an active young focusing system can otherwise disguise the true power.
What a comprehensive eye check includesThere is no single best treatment — only the one that fits your age, your number, your cornea and your life. Here is the full range available at our centre, and who each option usually suits.
Not everyone is a candidate for every option. Suitability, benefits and risks depend on your prescription, corneal thickness and shape, age and overall eye health, and can only be determined after a detailed evaluation with our doctors.
Glasses correct today’s vision but do not slow tomorrow’s increase. Myopia management is a separate plan, and the earlier it starts, the more years of progression there are to influence. Our specialists build it around your child.
Power and axial length recorded each year, so progression is measured rather than guessed at.
Overnight lenses studied specifically for slowing progression, with clear glasses-free days as a bonus.
A specialist-supervised nightly drop used alongside glasses where progression is documented.
Around two hours of daylight a day, plus breaks from near work — small, free and genuinely protective.
Myopia management may slow progression in many children; it is not a cure and does not guarantee that a child’s power will stop increasing.
A highly myopic eye is a longer eye, and a longer eye has a thinner, more stretched retina. That raises the lifetime risk of several conditions — which is exactly why a dilated retinal examination belongs in your routine check, whether or not you wear glasses comfortably.
Retinal detachment — a stretched, thinner retina is more prone to tears and detachment, which is a surgical emergency.
Myopic macular degeneration — stretching at the centre of the retina can permanently affect detailed vision in very high myopia.
Early cataract — cataract tends to appear earlier in highly myopic eyes than in others.
Glaucoma — the risk of raised eye pressure damaging the optic nerve is higher, so pressure checks matter.
These are not part of ordinary myopia. If any appear — especially with a high number — get examined the same day.
A sudden shower of new floaters — dots, threads or cobwebs drifting across your vision.
Flashes of light, especially in the corner of your vision or in the dark.
A dark curtain or shadow moving across part of your field of vision.
A sudden drop in vision, or straight lines that begin to look wavy or bent.
Eye pain with redness, haloes around lights, or vision that clouds over quickly.
Habits will not remove an existing number, and no exercise reverses myopia. But in growing children, how the eyes are used every day genuinely influences how fast the power climbs.
Daylight exposure is the best-supported protective habit for children. Outdoor play counts; so does the walk to school.
Every 20 minutes of near work, look at something about 20 feet away for 20 seconds. It eases strain and breaks sustained focus.
Books and screens roughly an elbow’s length from the eyes, not resting on the nose. Sustained very-close work is the pattern to avoid.
Dim light does not cause myopia, but it does cause strain and encourages children to move closer to the page.
Age-appropriate limits with real breaks work better than blanket bans — particularly for study-heavy schedules.
The only way to catch a rising power early enough to act on it. Book it with the school year, not after the marks drop.
Every option under one roof — glasses, contact lenses, Ortho-K, atropine, LASIK, SMILE, Contoura Vision and ICL — so the advice is not shaped by what we happen to offer.
Contoura Vision and SMILE together — the only centre in Gurgaon offering both, which widens what is possible for your cornea.
Paediatric myopia management — axial length tracking and a written control plan, not just a new prescription every year.
Retina care in-house — high myopia is followed with OCT and dilated examination by our retina team, in the same building.
NABH-accredited, 20+ years — senior specialists, 1.2 lakh+ surgeries, and transparent pricing with Easy EMI arranged by our counsellors.
