i definitely like the app! it seems pretty extensive when it comes to eye tests! haha... instead of having the device as a setting, you should use [ScreenMode = Mojo.Environment.DeviceInfo.screenHeight;] and then you can do an if statement to check [if (ScreenMode == 480). also, how did you make the video? i think the background and flow are pretty sweet. i definitely need to start making and loading some vids into the app catalog for my collection of apps. sorry for the delay! cheers!

@Commando303X The lively musical punctuations help get me through the dull narrated parts. If you get stuck at 3:46 due to boredom from the dull narration, try your best to hang in there: you will be rewarded with a lively musical punctuation at 4:15, and this will likely get you through to the end.

@maryjanemars That depends on the State requirements. They run from 20/60 for Georgia, and 20/50 for the State of Texas. Almost all the rest require 20/40 with 1) Both eyes open or, 2) With the better eye. The 20/40 letter is 3/4 inch high to be read at 20 feet. Metric, 1.8 cm at 6 meters.

In most countries the 20/40 line which was PECFD in the video. If your visual acuity is worse than this without glasses you need glasses to drive and the test will be done again with your glasses on.

The bottom line. The goal is to show that the eye resolves to 1 minute-of-angle at distance. At 20/40, that is 2 minutes-of-angle. The 20/20 letters subtend 5 minutes of arc.

Snellen 20/20, means the letter is 3/8 inch high. for 20/40 the letter is 3/4 inch. For metric, the letter is 0.9 cm fo 6/6 vision and 1.8 cm for 6/12.
