Huanyu Manual Lensometer ±20D External Reading (AC 110V) | Outer Reading AC and DC Digital Lensometer Lens Meter Focimeter

Sturdy and accurate

I took off one star because it’s consistently off by about 0.25 (when measuring trial lenses), and I wish the numbers on the axis wheel were painted all the way around the wheel. Just FYI, the power switch has 3 settings: O (off), I (on), and II (I have absolutely no idea).

ESE PRODUCTO NO LO VOLVERIA A COMPRAR MUY MALO.

I am a Licensed Optician and utilized a Lensometer (manual, digital, various manufacturers) daily for 40 years. This Lensometer is fairly accurate, will analyze prism and identify the optical center of the lens. Not precise enough to scan for optical waves, but average person would not have the skill or experience to identify aberrations in the lens.However, this is the first Lensometer I’ve ever seen setup for a left handed person. A non issue for an occasional user novice, but very uncomfortable for someone trained on an industry standard model.

Economical. Does what it is supposed to do. Although the back lever that allows me to angle the lensmeter differently, has been stuck since purchase. I have to stack it on trays to use it comfortably.

Dosnt work at all. Dial dosnt move for the cylinder. The product was broken when received. Very disappointed.

Sent 2 and neater of them worked!
