Up to 15% back for an honest review

About two weeks after your lenses arrive I send you one request for a review. Leave one with a photo or a video of you wearing the glasses, drop me a line, and I refund part of what you paid.

I run BananaOptics on my own. I cut the lenses, I answer the emails, I pack the boxes. A review from someone actually wearing the glasses does more for a shop this size than any advert I could buy, which is why I am willing to pay for one. I do not give out discounts lightly otherwise. Ken

What counts

The photo or the video has to show you wearing the glasses. A shot of them lying on a table does not count. The point is to show how they actually sit on a real face, which is the one thing nobody else on the internet has.

It does not have to be a good review

The refund does not depend on the rating. One star earns exactly the same as five stars. I would of course be glad if you like them, but that changes nothing about the refund. I publish every review as it was written, and I do not delete one for being critical.

How to claim it

Once your review is published, email me at contact@bananaoptics.com and give me your order number. I refund within five working days, as a partial refund on your original order, so it lands on whatever you paid with. One refund per order.

Clear vision in the ski goggle you already own. No glasses squeezed underneath, no contacts drying out at altitude. The insert carries your prescription and sits behind the goggle lens, so the goggle keeps its own lens, its own look and its own fog protection. Single vision, progressive, astigmatism and strong values are all made here, to your numbers.

Not sure an insert is the right option for you? The three options for prescription ski goggles, compared by prescription, in five minutes.

Fitted in these goggles, and every other one I have tried

All eight photographed on the same day with the same V3 insert. I have not yet found a goggle it will not seat in. If yours is not listed, send me the model and I will check it before you order.

Tested, insert seated, photographed: Smith 4D MAG, Oakley Flight Deck M, Oakley Line Miner L, Smith Squad, Anon M4 Toric MFI, Oakley Fall Line M, Smith Reason OTG, 100% Strata 2.

Same frame in a larger size, fits too: Oakley Flight Deck L, Oakley Fall Line L, Smith Squad XL. A bigger frame only gives the insert more room.

Smaller sizes, expected to fit, not tested yet: Smith 4D MAG S, Oakley Line Miner M and S, Smith Squad S, Anon M4S. These I want to check in hand before I say yes, so send me the model.

The full list, one row per model and size, with every result: which goggles fit the prescription insert.

It sits where your glasses sit

Most goggle inserts park the lens wherever the goggle happens to hold it, which is further from the eye than your everyday glasses. That is why an insert can feel wrong even when the prescription is right. The V3 insert adjusts in two directions to fix that.

Height. The lens holders clip into a ladder of holes in the bridge, 3 mm apart. I choose the hole from your pupil height, so the centre of each lens sits in front of your pupil and not at an average.

Height adjustment explained: the hole ladder in the bridge of the V3 goggle prescription insert, 3 mm per step, set to your pupil height
The hole ladder. Each step is 3 mm. I pick the hole from your pupil height before the insert ships.

Depth. The insert holds itself in place with four arms that rest against the inside of the goggle, on the lens or on the rubber around it depending on the model. Without an adapter the prescription lens sits at its outermost position, furthest from your eye. Three push-on adapters, 5, 10 and 15 mm, ship with every insert. Pushed onto the bridge, each one moves the lens that much closer to your eye, back to the distance your own glasses sit at. For stronger prescriptions and progressives this is not a comfort detail: lens distance changes the effective power, and the further out a lens sits, the more the correction drifts. Setting it right is what makes a strong prescription work in a goggle at all.

Depth adjustment explained: the 5, 10 and 15 mm adapters and one pushed onto the bridge of the V3 goggle prescription insert, moving the lens closer to the eye
Top: the three adapters. Bottom: one pushed onto the bridge. 0 mm without, then 5, 10 or 15 mm closer to your eye.

Very high prescriptions are what I specialise in

Most suppliers stop at moderate values. I do not. Sphere from +5 to -7.5 is standard. Beyond that I work with a specialist lens lab: cylinders to -8, prism, and combinations other suppliers turn away. Two things make a high power work in a goggle where it fails elsewhere. The lens has to sit at the distance your prescription was measured at, which is what the depth spacers are for. And each lens has to be centred on your own pupil, which is why I ask for monocular measurements. Send me your values and I tell you honestly what is possible before you pay anything. The numbers behind all of this, vertex distance, fitting height and what each millimetre costs in dioptres, are in the high prescription ski goggle guide.

Which insert you get

Every order is built on the adjustable V3. For a very low single vision prescription I may fit the fixed V2 instead: it is optically simpler and looks cleaner in the goggle, and at low power the adjustments make no difference you would notice. I decide from your prescription and tell you which one is coming before it ships.

Magnetic lenses still swap

On the Smith MAG and Anon MFI goggles the lens still lifts off and snaps back with the insert in place. Photographed, not assumed.

Delivery and returns

Made to your prescription and shipped in about two weeks. 50 day returns. Not sure about your goggle or your values? Free check by chat or email, and I tell you exactly what is possible before you pay anything.
