Equipment Preview: Corvis ST

The Corvis ST (by Oculus) is an applanation tonometer with a rather special difference...

Augmented Reality: Part 3

In part one we had a brief overview of augmented reality spectacles, predominantly from Project Glass (Google Glasses). In part two we took a look at Innovega Inc.'s amazing contact lens design for augmented reality displays. Today I want to look at some of the patents behind Google's augmented reality effort. Join me after the break...

Gorilla glass glasses?!

A tiny bit of conjecture for you all this morning having just had a patient in with some particularly wrecked spectacles. Why not use Gorilla glass!? Follow me after the break as I go bananas about this new type of glass...(couldn't resist that, sorry)

App Review: Parks 3 Step

 Made by Dr Robert Burke at Calgary Vision Centre, the Parks 3 Step app aims to simplify the potentially troublesome binocular vision test for those practitioners with an iPhone (it's not yet available on Android). It's up on the App Store for £0.69 ($0.99).

Discussion topic: automated refraction booths

Bit of a heavy topic for a Thursday evening but none the less an important one. In Hong Kong they have booths on the street which can perform a full refraction routine, including subjective refraction. They're apparently accurate enough to fall within the British standards required for refractive accuracy. Obviously if these landed in the UK (legal provision of sight test issues aside) they would pose a threat to the "quick refraction to produce sale of spectacles practices" more than the clinically high end whom aren't as reliant on spectacle sales.

But would they also threaten the core role of optometry in the UK? Thoughts below!

Augmented Reality Part 2: Contact Lenses

As if augmented reality glasses weren't enough of a mind bender Innovega Inc (no I'd never heard of them either) have announced a special contact lens which allows augmented reality displays to be focussed from one inch!

There's a great video demonstration of that after the break (albeit with a camera so not a really fair comparrison to the human eye...that didn't stop the Pentagon though!)...

Advanced Binocular Refraction Seminar

Just a quick summary for those who couldn't make the conference hosted by Carl Zeiss Vision and Supervisionaries. Its been a fantastic two days and I think my brain will take some time to recover from the information overload. The seminar was on the MKH (correction of heterophoria according to the methodology of J-Haase) technique used widely on the continent but very rarely here....continued after the break

Augmented Reality

Augmented reality displays are only ayear or two away (at most) and we already know that Oakley and Google are definitely releasing some. Find out after the break what on earth this means for optometry?

The 3D display knowledge gap

3D displays are becoming more prevalent yet there is very poor understanding of their mechanisms by the vast majority of Optomertists.

There are two main types: polarised glasses and parralax screens. I'm sure we all understand the demands that a polarised stereoscopic image has on the binocular vision system, but how many feel comfortable with the workings of parallax screens?
How do they affect patients binocular status?

Are you in your practice ready for the ongoing 3D revolution or are you being left behind and not able to care fully for your patients?

Look out in your optometry magazines for upcoming information articles about this in the near future.



Welcome to the technology blog for optometrists. I hope to be able to bring news, views and opinion on the latest developments in the technology sectors and the impact they have on optometry. With augmented reality displays and holographic displays coming in fast are we prepared as a profession for the huge leap is visual demands that will occur in the next ten years?

I hope you have fun reading and discussing the points. Please feel free to email any topics you'd like me to cover.
