Lensometers are super simple pieces of technology. Sure- there’s that refraction of light piece that takes some advanced calculation from intricate circuitry boards- but other than that they’re slender towers with a display and some ink-marking pens along the way. Canton understands that simplicity and yet delivers a lensometer that sticks to the root fundamentals while providing some unique perks along the way. But before we dive into those goodies- understand that the Canton does everything you’d expect a lensometer to do and it does it very well. A green LED light source provides instant, powerful feedback, and the user interface is controlled by touch and is very well thought out. It’s ergonomic, responsive, and stylish. It reaches beyond your standard lensometer by providing terrific interfacing capabilities; USB, WiFi, RS-232C, and Bluetooth communication all come standard. With the being said, most EHR platforms haven’t written gateways for the Canton device, and when we tried to connect it to some major EHR Cloud providers, we ran into some issues that took some time to resolve. It also won’t connect to any digital refractions system you’re currently using. Knowing this, we were however able to transfer data to Android mobile devices and send the data from there. A cool party trick for those in mobile practice or maybe those that want lensometer data on their phone?


OUR TAKE: A great basic-yet-advanced lensometer choice for those not requiring digital refraction integration (ie. connecting to your Digital Phoropter)

*based on CPT 92015 assuming determination of refractive state

At long last, a Lensometer as advanced as the lenses it can now measure. The new 7” TFT Color LCD touch-display features details and neutralization refresh rates like never seen. Neutralizing lenses has never been easier- and, with the all-new 108-point refractive processor, accuracy is unmatched. Wavefront sensors use an array of lenses of the same focal length to measure the bending of light through virtually all types of lenses— detected automatically. 

Pixels. Color. Touch.

LM800 packs over 1 million pixels into a 7-inch display. And at the touch of a finger, the all-new designed user interface allows seamless navigation, clearing, and printing. Auto detection of lenses lend a simplified user-experience, allowing for ultra-quick neutralizations, and swift setting revisions. Bold fonts, minimal design, and spacial graphics make for lensometry quicker and more efficient than ever before.


  • Titltable user display for any operator position.
  • 60Hz refresh rate for instant lens feedback.

Optical. Capable beyond its size.

Not only does the lm800 automatically detect virtually any form of optical or contact lens, pupillary distance, pupil height, and progressive channel height measurements all come standard. Advance interface graphics make lens power acquisition a cinch- even on progressive and other multi-focal lenses. A magnetic nosepiece slides effortlessly with natural hand movements- even with large or narrow frame bridges. Lightweight ink markers have been slimmed down for ultimate precision and the polyethylene lens clamp moves effortlessly with minimal touch.

UV Transmittance:

Measure UV lens protection and blue/green light exposure, all at once.

Green LED Pathway:

LM800 employs specials green LED wavelengths to produce a more precise measurement.

LM800’s bold-text thermal printer produces rapid printouts with high-contrast for ultimate readability. The same data can instead be transferred automatically to a connected device, instead of printed.

Yes, the LM-800 now connects to any Android device via Bluetooth or WiFi – sending lens data instantly without any corded connection. Don’t have an Android device? LM-800 can still store, archive, and transfer data via USB and RS-232C connection.

You bet. The lm800 offer a tillable display for standing or sitting operating positions.

Yes, the LM-800 automatically detects virtually any form of optical or contact lens, pupillary distance, and pupil height.

The lm800 has a built-in thermal line printer that automatically prints data in a traditional lensometer format.

You bet. Any form of contact lens can be measure with the lm800.
