Polarised or Photochromic? Sports Lens Tints for Scotland

A child almost never says “I think my vision is affecting my football”. What they say is that they do not fancy it this week. What the coach says is that they are not concentrating, or that they have stopped going for the ball in the air.
That gap between what a visual problem actually is and how it presents in a nine-year-old is the single most useful thing for a parent to understand. Children have no baseline for comparison. If the ball has always been slightly blurred at distance, or if their eyes have always struggled to work together as a pair, they assume everyone sees it that way. They do not report a problem. They quietly avoid the situations that expose it.
This is a guide to the practical side: what to buy, when, to what standard, and what questions to ask. All of it sits alongside our children’s eyecare service.
Stage | Usual setup | What parents most often miss |
|---|---|---|
Primary school PE | Impact rated frame, polycarbonate lenses | Assuming school PE is low risk because it is not competitive |
Club football & rugby | Impact rated frame with retention strap | A strap on an ordinary frame is not a sports frame |
Squash & racquet sports | Certified eye protectors to ISO 18527-2 | Not knowing certified protection is mandatory in junior championships |
Swimming lessons & club | Prescription goggles to their correction | Buying goggles in rough half dioptre steps off a shelf |
Cycling to school | Photochromic, secure fit, UV rated | Dark tints on dark winter mornings |
Teenage competitive sport | Contact lenses often become the better answer | Waiting for an arbitrary age rather than assessing maturity |
If your child is in more than one row, you probably need more than one solution. That is normal, and it is usually cheaper than people expect once the prescription work is done.
None of these prove there is a problem. Any two of them together are worth an appointment.
It is also worth knowing that a school vision screening is a screening, not an eye examination. It is designed to catch obvious distance vision problems and does a reasonable job of that. It is not designed to assess how the two eyes coordinate, how quickly they change focus, or the health of the eye, and children pass screenings while having something meaningful going on.
Most children who play sport in glasses are playing in their everyday pair, because nobody suggested otherwise. Three problems follow.
The baseline for sport is an impact rated frame in a material that deforms rather than snaps, fitted with polycarbonate or Trivex lenses. Both materials are substantially more impact resistant than standard plastic and are the default we fit for any child playing sport.
For most sports, impact rated eyewear is a strong recommendation. For racquet sports it moves closer to a requirement, and squash is the clearest case in the whole of junior sport.
A squash ball is close to the size of the eye socket and travels fast in an enclosed space. The World Squash Federation requires juniors, defined as under 19, to wear appropriate protective eyewear in its team and junior individual championships, and recognises eyewear certified to ISO 18527-2:2021, BS EN 18527-2:2021 and ASTM F3164-19. Many Scottish clubs apply the same rule at junior sessions regardless of competition level.
This applies whether or not your child needs a prescription. Protective eyewear for squash is protective equipment first, and a correction second. Plenty of juniors with perfect vision should be wearing it.
If your child plays squash, badminton or racquetball, ask the club what standard they require before buying anything, then bring that requirement to the appointment. We would rather fit to the club’s specification than have you buy twice.
The question we are asked most often by parents is whether their child is old enough. It is the wrong question. Age correlates loosely with what actually matters, which is maturity, motivation and hygiene.
A ten-year-old who is genuinely motivated, follows instructions carefully and has good hand hygiene will often manage daily disposable lenses better than a fifteen-year-old who is not interested. In sport specifically, lenses solve several problems at once: nothing to displace in a tackle, full peripheral field, and no frame between an elbow and the eye.
Daily disposables are usually the sensible starting point for young wearers, since there is no cleaning regime to forget and a lost lens is an inconvenience rather than an expense. We assess suitability individually as part of a contact lens fitting, and we will tell you honestly if we think a particular child is not ready yet.
If your child’s prescription is getting stronger year on year, there is a conversation worth having that goes beyond which frame to buy.
Progressive short sightedness in childhood is not simply a matter of needing stronger lenses each time. Higher levels of myopia carry increased long-term risk of eye health problems in adulthood, which is why slowing the progression matters rather than just correcting it. Myopia management covers the approaches available, and the consistent finding across all of them is that starting earlier produces more benefit than starting later.
Sport is relevant here too. Time spent outdoors is associated with slower myopia progression in children, which is one of the few pieces of eye health advice that costs nothing and that most children enjoy.
A children’s appointment with us runs the same full forty minutes as an adult one, which matters more with children rather than less. Testing a child properly takes patience, and a rushed appointment produces an unreliable result.
NHS-funded eye examinations in Scotland are available annually for children under 16. There is no reason to wait for a problem before the first one.
If you coach junior sport in Glasgow and you have a player who has gone quiet, drifted to the periphery, or stopped competing for high balls, it is worth a word with the parents before concluding it is confidence or commitment. It costs nothing to suggest, and it is one of the more common preventable reasons children leave a sport.

If they play contact sport, racquet sport, or any sport involving a fast-moving ball, yes. Everyday frames are not impact rated, they slip when a child sweats, and they break easily. The baseline for children playing sport is an impact rated frame with polycarbonate or Trivex lenses, which are substantially more impact resistant than standard lens materials.
There is no fixed age. Maturity, motivation and hygiene matter far more than the number. A well-motivated ten-year-old often manages daily disposable lenses better than a disinterested fifteen-year-old. Daily disposables are usually the sensible starting point for young wearers because there is no cleaning routine to forget.
Impact rated sports eyewear is considerably safer than ordinary spectacles for sport, and safer than playing with no correction at all. The materials are chosen to absorb impact and deform rather than shatter, and proper retention keeps the frame in position. The unsafe option is an everyday frame in a contact environment.
In World Squash Federation team and junior individual championships, juniors under 19 must wear appropriate protective eyewear, and the WSF recognises eyewear certified to ISO 18527-2:2021, BS EN 18527-2:2021 and ASTM F3164-19. Many clubs apply the same rule at junior sessions. Check your club’s requirement before buying, and note that this applies whether or not your child needs a prescription.
Yes. A school screening is designed to catch obvious distance vision problems and does that reasonably well. It does not assess how the two eyes coordinate, how quickly they change focus, or the health of the eye. Children pass screenings while having something meaningful going on, particularly binocular vision problems.
