Gizmo Supply Digital LCD Optical Pupilometer (CE Approved)

Buying glasses from online retailers can be convenient and inexpensive. However, many buyers have difficulty measuring their pupillary distance (PD). Instead of using some of the bootleg (and potentially inaccurate) methods of measuring PD I decided to buy this pupilometer figuring that it would more than pay for itself if I was able to successfully buy glasses online. Well, it worked like a charm! My 10 year old son was easily able to measure my PD. I also had a coworker who used to work in an optical shop verify his measurement and he was spot on. Ordered my glasses from an online retailer and they turned out fantastic.I would have really given this unit a 4.5 star rating if I could only because the included instructions were AWFUL. I don't think they even conincided to this unit. Be aware that the unit requires 1 AA battery which is not included. Regardless of the poor instructions, you can easily figure out how to use the unit from doing a couple Google searches. Otherwise, I highly recommend this unit.

Poor quality and did not have ability to measure a near pd.

Had some trouble getting the item delivered, but the seller addressed that promptly. Item works great, easy to use if you google for instructions. Saved money buying glasses for three kids who need a new pair ever year. Thank you.
