What HOYA MiyoSmart IQ is
MiyoSmart IQ is a lens in Hoya’s MiyoSmart family, a spectacle lens made for children whose myopia is progressing. Like the lenses before it, it looks like an ordinary single vision lens from a conversation distance. The child looks through a clear central zone for everyday seeing. The myopia control element sits in the surrounding area of the lens.
MiyoSmart IQ builds on the design of the earlier MiyoSmart lens rather than replacing the idea behind it. Hoya’s own product information for the MiyoSmart range is the place to read the manufacturer’s full description.
From D.I.M.S. to D.I.M.S.+: what Hoya changed
The treatment pattern takes the shape of the eye into account. It should therefore land more consistently for the wearer. It is an evolution of a design that already worked, not a different technology wearing a new name.
Why the periphery of the lens matters at all
The principle is worth understanding. It explains why you cannot simply buy these lenses as a strength off a shelf.
In myopia, the eye focuses light from distant objects in front of the retina rather than on it. A conventional single vision lens corrects that for the point the child is looking at. That point is straight ahead, through the optical centre. Light arriving from the side lands on the peripheral retina, and that is a separate matter. Peripheral defocus has been the focus of myopia control research for two decades. Lens designs of this type, MiyoSmart included, manage what happens to that peripheral light. They leave central vision clear.
Two things follow from that. First, the clear central zone has to sit in front of the pupil. That is a fitting question, not a prescription question. Second, the treatment area only works as the designer intended. The lens must sit on the face the way the designer assumed. A lens like this asks more of the frame than an ordinary one does.
How the lens is made
A child will wear this lens through school days, sport and the daily business of being knocked about. The material therefore matters as much as the optics.
One practical note for parents: frame shape and the lens design depend on each other. That is a real constraint on frame choice. So settle the lens and the frame in the same conversation rather than one after the other.
MiyoSmart IQ and the rest of the MiyoSmart family
MiyoSmart is not a single product.
The sun lens matters more than it sounds. Outdoor time is part of every serious conversation about childhood myopia. Children who spend real time outdoors will squint, take their glasses off, or simply stop wearing them in bright light. A second pair follows the same design in a tinted lens. The correction and the treatment then carry on where children spend the brightest hours of the day.
Whether a family wants one pair or two is a decision about how a particular child lives, not a rule. What is worth knowing is that the option exists.
Choosing the frame: what a myopia control lens asks for
We carry luxury eyewear and unique designs from small independent houses. These are frames you will not find in a chain. We choose them because they are beautiful and made well. Design, proportion and how a frame suits a face come first here; fit is what makes a good-looking frame wearable. With a lens of this kind, that second half does real work.
A few frame qualities count for more than usual:
- A shape deep enough to hold the design. Very shallow or heavily cut-away shapes leave little room for the treatment area once we edge the lens.
- A bridge that holds position. A frame that slides down the nose moves the clear central zone with it. Adjustable pads or a well-judged fixed bridge both work; a bridge that is simply too wide does not.
- Temples that hold their adjustment. Titanium and good acetate both take an adjustment and keep it. A frame that needs straightening every week is a frame that spends most of the week out of position.
- Weight the child forgets about. Glasses a child actually wears are glasses that work.
We are an authorised dealer for Lindberg‘s titanium and acetate work. Our range also includes houses such as ic! berlin, Anne et Valentin, Masunaga and Lafont. Frames arrive in small, considered quantities. We choose each one for how it fits and feels on a person, not simply for how it looks on display. In-house, we also make bespoke handmade spectacles, cutting the acetate ourselves from our own colour range. We are the only optical boutique in Singapore doing this.
The fitting, and why it cannot be done from a photograph
At every fitting, we begin with the essentials: comfort, balance and eye position. We also check how the frame sits across the bridge and temples. With MiyoSmart IQ, those are not comfort details alone. Eye position in the frame is the thing the lens design depends on.
At a fitting, we measure the horizontal distance between the pupils. We also measure the height of each pupil within the chosen frame. We take both with the frame already adjusted to the child’s face. Vertex distance, pantoscopic tilt and the wrap of the front all change where the lens sits relative to the eye.
Many frames follow a higher bridge profile, so we pay particular attention to fit for Asian facial features. The frame then sits securely and comfortably, without slipping or resting on the cheeks.
This is the argument against choosing a child’s glasses from a website. A photograph is useful for inspiration. You can only really judge fit, proportion and comfort when you put a frame on. This lens design assumes a particular position in front of the eye. That position is not a detail you can guess at from an image. Children also grow, which is why a frame fitted in March may need reseating by August.
MiyoSmart IQ next to the other approaches
Spectacle lenses are one of several routes open to families, and it is fair to set them side by side.
Myopia control contact lenses
Daily disposable soft lenses designed for myopia control suit some children well. They particularly suit those who swim or play sport, where glasses are a nuisance. Such lenses ask for clean hands, a routine and a child ready to manage them.
Low-dose atropine
Eye doctors prescribe and monitor atropine eye drops, which sit outside what an optician supplies. Some families use drops alongside spectacles; that is a conversation for the prescriber.
Habits and time outdoors
Time outdoors comes up in every discussion of childhood myopia, as does how close a child holds a book or a screen.
None of these rules the others out. A spectacle lens has simplicity in its favour: the child puts the glasses on in the morning, and that is the whole routine.
Living with the lenses: cleaning, damage and replacement
Care is straightforward. Rinse first under a running tap to float off grit, then dry with a clean microfibre cloth. Dry-wiping a dusty lens is how most scratches happen. Hot water, alcohol wipes and shirt hems all shorten a coating’s life.
Prescriptions in growing children change, sometimes more than once a year. When they do, you do not need to replace a frame in good condition. We can glaze new lenses into the existing frame, provided it is still sound and still fits. See lens replacement for how that works.
Replace a lens with a chipped edge or a deep scratch across the centre, rather than living with it. A child may say the glasses feel fine while you can see them sitting low on the nose. Bring them in — the position is worth resetting whether or not the child has noticed.
Questions worth asking before you commit
Coming to this decision with a few questions ready makes the appointment more useful:
- What does Hoya’s own published material say about this lens? And how does the IQ design differ from the MiyoSmart lens my friend’s child wears?
- Will this frame shape hold the lens design once we edge it?
- How often should the glasses come back for readjustment, and is that included?
- If the prescription changes in six months, what happens to the frame?
- Does a second pair for outdoors make sense for how this child actually spends the day?
We have been fitting spectacles in Holland Village for nearly twenty years. The best way to settle any of it is to bring the child in and try frames on. The lens is Hoya’s work; making it sit where Hoya designed it to sit is ours.
