A couple weeks ago I bought this “ucansee” trial frame kit / trial lens set on Amazon for $220. It’s currently “unavailable” on Amazon but I’ve seen it from other web vendors and direct from the ucansee.us site. I was concerned about spending the money without the support of some review articles or knowledge of the product, but all worked out. I thought I’d save some others some bother and worry by sharing the info.
See the end of this post for the manifest of included lenses and other items.
A determining factor: lens dimension out-to-out: 38 mm
Only the “ucansee” product listing specified their lenses as “industry standard 38 mm”. That was one of the main reasons I bought this kit, knowing I would be buying the frame separately and it would have to accept the size lenses from the kit. It turns out that 38 mm really is “standard” (for metal anyway).
See my separate review of the lens frame I bought.
The frame (“eyeglasses skeleton”) that comes with the kit is a “pretend product” – “total toy”. The fatal flaw is the fixed PD’s which come with this category of item (sample frames in kits). If it’s not your PD, too bad for you…
Price point in scanning amazon and the web (and listening to a Jake youtube on the subject I think) I concluded that $100 (min price bracket I saw) was too low – mainly because that range includes only about 100 pieces. I didn’t want to get stuck having to buy extra pieces after supposedly buying a full kit.
I was also convinced by one product’s sales pitch that cases made of wood, fiber, cloth etc look nice when new but dry up, warp, split, mildew etc – better to go with metal case and plastic liners.
“Build” quality: no complaints – no projecting burrs in the aluminum case, the top lines up well and the lens holders are smooth and properly formed. Minor complaint: the case dents rather easily.
Trial lens frame material (the holder for each lens): I prefer metal just for aesthetics but after watching some youtube howtos I saw that professionals all had plastic (so it’s likely a decent lens holder material). Also the plastic framed lenses seem to go in and out of the frames easier than the metal (per the prof’ls on youtube videos) – though that could be mostly due to the higher-end lens frames too.
Don’t drop / break those lenses! I had to contact three optician/optometrist supply houses online to get one who would not require “a doctor’s RX” to sell me a single glass lens…geeez what a racket!
Summary: does the job, worth the money (IMHO)
