How to fit shooting glasses on a child: five checks at the kitchen table

There is no youth size in the standard

This is the fact that makes the whole exercise necessary. ANSI/ISEA Z87.1 tests a device — a frame and lens assembly, on a head form — and it certifies that the device passed. It does not define a youth category, a child's head size, or a minimum coverage area relative to a face. So "youth shooting glasses" is a frame-size claim made by a manufacturer, in its own words, with no standard behind the claim.

Those words are worth reading precisely, because they differ. Walker's says the Clearview Youth is "engineered specifically for smaller heads with wraparound design". Radians says the Ducks Unlimited DU-Y1 is "specifically designed to fit smaller heads and faces". Pyramex says the Mini Ztek is "a design better suited for slimmer facial sizes" — slimmer, not smaller, which is a different claim and suits a narrow-faced teenager better than a small child. Radians also sells a MICRO shooting glass it describes as a 10% smaller frame for youth, ladies or anyone wanting a smaller frame, though the page we read does not state an ANSI rating, so it does not get a card here.

Nobody in this category publishes an age range, and you should be glad: heads vary enormously at the same age. Fit it to the face in front of you.

Two measurements before you order

You only need two, and a soft tape or a piece of string will do.

Temple-to-temple width. Measure straight across the face from the outside of one temple to the other, at eye level. This is the number that decides whether a frame rocks. If a frame's total front width is appreciably wider than this measurement, it will sit on the cheekbones and slide down no matter how you adjust it. Very few makers in safety eyewear publish a front width, which is why the ones that do are worth seeking out — Revision publishes the Sawfly at 144 mm for Small and 157 mm for Large, and the Bollé Tryon OTG at 132 mm.

Ear-to-eye length. Measure from the outer corner of the eye back to the point where the ear meets the head. This decides whether the temple arm reaches far enough to bend behind the ear rather than pressing on the side of the head. Where makers publish a temple length, compare it to this: the Edge Hamel's 140 mm and the Revision Sawfly Large's 180 mm are adult numbers, and a child needs far less.

Write both down. They stay useful for years, because they let you order online without a fitting and they let you tell whether the pair you already own has been outgrown.

The five fit checks, in order

Do these with the glasses on the child, in daylight, before the first range trip rather than at the range.

One: coverage. The top of the lens should sit above the eyebrow and the bottom should reach the cheekbone. If the eyebrow is above the lens, there is an open channel for anything arriving from above — which on a firing line is a hot casing and in the yard is a wood chip. If the lens stops short of the cheekbone, the whole lower field is open. Coverage comes before comfort because it is the thing you cannot adjust.

Two: the bridge. The frame's weight should sit on the bridge of the nose with the lens close to but not touching the eyelashes. Touching lashes means the frame will get pushed up within minutes. A visible gap of more than a few millimetres between the lens and the brow means the frame is too large. Rubber nose pieces — the DU-Y1 and the Mini Ztek both have one — make a real difference here because they stop the slide rather than just cushioning it.

Three: the temples. The arm should run straight back and begin to curve after it has passed the ear, not before it. An arm that bends early presses into the side of the head and leaves a red mark; an arm that is far too long levers the frame off the nose. Flexible temples with rubber tips, which Radians states for the DU-Y1 and Pyramex for the Mini Ztek, forgive a lot of this.

Four: the shake test. Have the child look down at their shoes, then shake their head side to side twice. If the glasses move more than a millimetre or two, they will move during a gun mount. This is the single most informative test on the list and it takes three seconds.

Five: the mount test. With an unloaded firearm, or a broom handle if you are at the kitchen table, have them take the shooting position they will actually use. Watch the glasses. If the stock comb touches the frame, or the frame shifts as the cheek comes down, the frame is sitting too low — and a young shooter will respond by lifting their head off the stock, which is a miss and a habit at the same time. Fix the frame, never the cheek weld.

Testing the fit under ear muffs

Do this as a separate step, with the muffs the child will wear, because almost every fit that works bare-headed fails here. A muff cup seals against the side of the skull, and a small head gives it less room; the cup lands directly on the temple arm.

Two things to look for. Does the cup lift the glasses off the nose when it settles? That is the arm being too thick, and the answer is a thinner temple — the frameless clay frames with thin metal temples are the best thing on this site for it. And can you see daylight between the cup and the head where the arm crosses? That is a broken acoustic seal and it costs real hearing protection, which matters more than the eyewear question you came here to solve.

If both fail, the answer is usually to change the glasses rather than the muffs, because muffs that fit a child are harder to find. The frames that clear a cup, and why, are on best shooting glasses for ear muffs, and the combined-system view is on glasses and ear protection combos.

Frames makers actually size for children

The full youth ranking, including the goggles for air-gun and airsoft use, is on best youth shooting glasses. If the shooting is trap rather than general range work, the tint question is covered on youth trap shooting glasses.

How to tell they have outgrown it

Four signs, and none of them involves a birthday.

The temple arms now bend before they pass the ear, leaving a mark. The lens no longer reaches the cheekbone when the child looks straight ahead. The frame slides down within a few minutes of putting it on, even with a rubber nose piece. Or they have simply started pushing it up onto their forehead, which is the behavioural version of the same message.

At that point the good news is that the options widen a great deal, because small adult frames are a real category with published dimensions: Revision's Sawfly in Small, Pyramex's Mini Ztek, and the frameless clay frames. Those are collected on best shooting glasses for small faces.
