Needs by age: 0-3, 3-7, 7-12

The 0-3 age range is generally for congenital or early-detected high hyperopia, strabismus, or — rarely — eyewear fitted after congenital cataract surgery. At this age the visual cortex is developing rapidly; the glasses are a medical tool to prevent amblyopia (lazy eye), not an aesthetic choice. The frame should have silicone temples, a flexible polymer body, and no nose pads; Miraflex Baby Plus and Tomato Glasses TKAC are our first recommendations at this age. The 3-7 preschool stage is when a child starts to own their identity as a 'glasses wearer' — let them choose the colour. The frame has to survive drops, chewing, and being put on and taken off twenty times a day. The 7-12 school years are when the risk of onset myopia is highest. As screen time and near work increase, myopic progression averages -0.50 to -0.75 dioptres per year; at this point myopia control lenses should be on the table.

Myopia control lenses: MiYOSMART and Stellest

Childhood myopia is the fastest-growing topic in optics over the past decade. We used to say 'give them the prescription, they'll grow into it, it'll settle'; today we know that when myopia progresses beyond -6.00, the risk of retinal detachment and glaucoma in adulthood rises significantly. Hoya MiYOSMART (D.I.M.S. technology) and Essilor Stellest (H.A.L.T. technology) both operate on the principle of 'peripheral myopic defocus': the centre of the lens carries the standard prescription, while the periphery contains microscopic lenslets that create defocus zones. By pushing the peripheral image in front of the retina, the eye is signalled to slow its elongation. Clinical trials on both products show roughly 60% slowing of progression over three years. We recommend them for children aged 8-14 whose myopia is progressing faster than -0.50 per year. They cost more than standard lenses (as of 2026, around 8,500-12,000 TL per pair), but considering the side effects of high myopia in adulthood, it's a long-term investment.

Impact resistance: polycarbonate and Trivex are mandatory

Let's be clear: we don't accept standard organic (CR-39) lenses for children. Polycarbonate is roughly 10 times more impact-resistant than CR-39; Trivex is even better and has superior optical clarity (Abbe value of 43, versus 30 for polycarbonate). If a child running around takes a ball, stone or stick to the frame, CR-39 will crack or shatter — and can cut the eye. Polycarbonate and Trivex flex, they don't break. The cost difference is modest; the safety difference is significant. For children who play sport we additionally recommend a protective frame (a sports model like the RecSpecs Maxx 30); you don't give a child playing football, basketball or tennis a standard acetate frame — the ball or a friend's elbow will turn those glasses into history. All our children's lenses are UV400 standard — a child's retina absorbs three times the UV of an adult's, and that matters not just for sunglasses but for prescription glasses too.

Frame durability: Lindberg Kid, Ray-Ban Junior, Tomato

We keep three brands of children's frames in regular stock for a reason. Lindberg Kid (particularly the Air Titanium and Spirit Kid ranges) weighs around 1.5 grams — even an adult Lindberg is only 1.8 grams. The screwless Danish engineering won't break when a child drops it; the only flex point is the temple hinge, adjusted in five minutes at the bench. It's expensive (over 10,000 TL) but lasts 4-5 years; the bridge and temple width can be adjusted to the millimetre as the child grows. Ray-Ban Junior (models RY1531, RY1592) puts the classic Wayfarer aesthetic into a flexible rubber-polymer temple; drop-resistant, in the 4,000-6,000 TL range. Tomato Glasses (made in Korea) is the world leader in the 6-month to 7-year range — silicone temples, screwless hinges, virtually impossible for a child to break. The anatomical nose design works without separate nose pads; 3,500-5,500 TL range. Miraflex is another solid alternative for infants and preschoolers. Etnia Barcelona Kids and Tom Ford Boy exist too, but the three above stand out for durability.

Fit and joints: sizing the child, not the adult

Children's frame sizing is interpreted differently from adult sizing. The nose bridge typically falls in the 14-18 mm range (versus 18-22 mm for adults); below age 7, if the bridge doesn't sit properly, the frame slides down and the child starts using it 'like a spoon,' looking out from above the lenses. For a low bridge, we recommend Tomato or models with silicone nose pads. Temple length is around 120-135 mm (adults run 140-150 mm); a soft silicone curve behind the ear is essential — hard metal pressing against the ear will lead the child to take the glasses off within 20 minutes and refuse to put them back on. Hinges should be spring hinges; when a child tugs on the glasses, the spring flexes and prevents the temple from snapping. We measure all of this with the child seated at the bench in the shop; many of the glasses people bring in for repair after buying online have these adjustments wrong from the start.

School performance: how glasses make a difference

The impact of properly fitted glasses on a child's school performance is bigger than parents expect. An 8-year-old who can't see the board clearly loses focus from boredom — and ends up labelled as 'disruptive' in class. If the prescription is wrong while reading, letters blur and the child says 'I don't like reading.' We always ask parents this question: 'At what distance does your child complain?' Distance trouble points to myopia; headaches at near reading point to hyperopia or astigmatism; asthenopic symptoms in both directions suggest accumulation problems; if a child wanders out of class with crossed-eye signs, a strabismus referral is needed. Schedule the annual eye check in summer, before school starts; when we detect a change in prescription, the new pair is delivered within a week — in time for the new school year.

Check-up frequency: every 6 months, not annually

An annual check-up is usually enough for adults, but children are different. Below age 6, the eye changes quickly — refraction should be checked every six months. Between 6 and 12, annual changes average -0.50 to -1.00 dioptre; that can be caught at six-month intervals but is sometimes missed at annual ones. Particularly when a fast progression is identified — for example, -1.50 in November and -2.25 by May — myopia control lenses should come into the picture. Come back to the bench every six months, even if no new glasses are needed, so we can check the lens condition, screws and hinges. Expect a child's glasses to retire after about 18 months of active wear; reusing a three-year-old frame with a fresh prescription looks economical on paper but doesn't fit the growing face.
