Sven Can See review: Keep your lenses mostly free from fog


Techaeris Rated 9/10

Occasionally we get some items in for review that aren’t exactly tech, but are somewhat tech-adjacent. That’s the case with Sven Can See. Sven Can See is a spray that goes on glass — think glasses, camera lenses, or other glass surface — that claims to keep those lenses from fogging up. Keep reading to see whether or not Sven can actually see in this full review.

What’s in the Box

1 x bottle (.27oz) Sven Can See spray
1 x lens wipe


The active ingredients in Sven Can See are listed only as “Biodegradable Surfactants” that are odor-free and non-toxic. You are, however, warned not to spray yourself in the eyes or ingest any of the liquid. This should all be pretty self-explanatory, but still, it’s best to get those warnings out of the way ahead of time.

Sven Can See packaging

The spray bottle is a small tube with a blue cap. The cap has a clip that attaches to a pocket or the strap of a bag for easy transport. You’ll also get a small square reusable lens wipe with the Sven Can See logo and wordmark in one corner. In addition to its use after spraying your lenses, the cloth is good for cleaning the lenses prior to spraying.


The instructions are really very simple: spray, wipe, and go. It’s probably best to wipe first as well to clean any dust or debris off of your lenses. Once you’re starting with clean lenses, just spray a few squirts onto either side of your lenses if spraying on glasses, or onto your camera lens, and then wipe it all around using the included cloth. It takes just a couple of seconds, and you shouldn’t see any sort of film or remaining liquid on your lenses when you’re done. It’s as easy as that.


Once applied, Sven Can See will prevent your lenses from fogging up under most normal circumstances. You aren’t going to be completely impervious — a particularly steamy shower or a Halloween mask will still give you problems — but if you wear glasses, you know that there are plenty of circumstances where your lenses will fog up and Sven Can See will reduce at least some of those circumstances for you.

With the winter season upon us, I’ve found my glasses fogging up significantly less when walking in from outside. That, if nothing else, is worth the price of admission for me. Sven Can See suggests that each use will last for a minimum of eight hours. I found that each application would usually last for a few days under perfect conditions. If your glasses get wet or dirty you’ll start to see a diminishing performance, but then it is easy enough to reapply when needed.

Sven Can See master-level challenge
It’s good, but Halloween masks are a master-level challenge.


Priced at $10.95 for each spray tube, Sven Can See is very reasonably priced. You should get quite a few uses out of each tube — I’ve sprayed my glasses roughly 10 times and still have plenty left.

Wrap Up

If you find your glasses or camera lenses fogging up frequently, Sven Can See can help keep some of that fog away so you can see or shoot clearly.
