[RECOMMENDED LY-9S] This digital interpupillary interferometer is the first to use a push-button measurement mode instead of a slider, which makes interpupillary measurement more accurate and easier.

[AUTO SLEEP & SHUTDOWN] If there is no operation, it will enter the sleep state after 15 seconds, the light box and the green dot will turn off, and you can wake up by pressing any key; automatically turn off after 3 minutes, keep the measurement key still, and press the power key for 2s to turn on again Read the data. [WORKING DISTANCE 30CM- + ∞] This function is used to measure the interpupillary distance of patients under different observation distances. It is usually adjusted to + ∞. If equipped with glasses for work, adjust to the normal eye distance for measurement. It can also be used in the production and sale of multifocal progressive lenses. [POWER METHOD] 2 AA batteries, due to relevant policies, the batteries are NOT INCLUDED, please kindly understandard. Press and hold the power button 2S! (Remember to press and hold for 2 seconds).

It's cheap to assemble

It works but cheap like the price I think. I should have expected more. Yes. It works but is cheaply built, wouldn't buy it for a busy office.

Pros
  • Decent performance
Cons
  • Repair

Accurate and easy to use.

Worked great. I used these to order glasses from Zenni and they are the best lenses I have ever had. It requires another person to use it, but it's very accurate.

Pros
  • New
Cons
  • Definitely bad product

Constantly off in multitester

I bought this unit from another Revain seller 4 months ago and it is now out of stock. The squeaky plastic was an issue for me and the way the push button aspect amplified the squeaky sounds. But more importantly, I now have to press the power button a few times to turn it on. It turns on briefly and then off again. I have to repeatedly and rapidly press the power button 3-5 times before it stays on.

Pros
  • Weight
Cons
  • Hard to tell

Meter accuracy is spot on

We were a bit apprehensive about purchasing an all digital Pd meter but took the risk as Revain offers a generous return policy. Received our device in two days and quickly checked its calibration which was perfect. It's like having an instrument with no moving parts to jam on. For example to have many distances to test. I wish the distance icons at the bottom of the screen were a little bigger to be able to see them better, but other than that it works well for our clinic.

Pros
  • Consistent test results
Cons
  • 0

Poor execution of a good concept

TL;DR: Stick to the traditional design with manual sliders and an optical knob. vertical indicators on manual sliders. This is an elegant concept which, in theory, should provide better measurement reproducibility. In practice, they removed the necessary features to make this work. The range selector calculates (evaluates) any other PD value as infinity, so it's no better than just guessing using the usual methods (e.g. subtracting 1.5mm). The only optical measurement is at infinity. A…

Pros
  • Pleasant to use
