Using the ipod or iphone for near acuity testing
« on: September 19, 2012, 06:29:15 am »
Hello,

I am inquiring about using the AT20P visual acuity tester for the ipod/iphone.  Can it be used independently from connecting to the desktop computer?  I already have a visual acuity software on my desktop computer but need a way to test near acuities. 

Any information is greatly appreciated.

Thanks,

Guy

Hi Guy,

The AT20P Acuity Tester is designed as a desktop only application. The closest it can be calibrated to is a distance of 1m. The iPod/iPhone is used to display a representation of what the patient display (PC monitor) is showing ONLY, it is not calibrated to be the true size. This is particularly useful when the patient display is being viewed through a mirror and is therefore inverted.

Thanks for your post!

Regards
David
