1) you must have either a 15", 17", or 19" monitor
2) you must have flash plugin for it to work
There are a few tips that should make this online eye exam more accurate:
1) have someone measure out the correct length that you should sit back at
2) keep a 1/4" black border around your screen monitor by using the monitor buttons
3) try not to squint
4) when you can no longer read more than half the words on a line, press stop
But the best online eye exam that I ever came across is Alejandro Saksida's Ultimate Random Snellen Eye Chart Generator.
In Alejandro's own words:
"Use (both on-line and off-line):"
"Load (need Flash player for this, you can download it from Macromedia's site or just try accessing the Snellen card, if you don't have the plug-in, automatically it'll take you where you can download the Flash Player)."
"A Snellen Card is something that gets old after some time if you have a specific one. This starts to become a problem when you remember every line without even looking at it. That happened to me more than once, limiting and falsifying my advance, that's why I've created this random letter Snellen chart. This chart not only generates random snellen charts but also Landolt C's, Tumbling 'E's and Pictures in different flavors."
The advance that Alejandro is talking about is an effort to improve his vision through using an eye chart and noting down a slow improvement in it, if at all!
I have already conveyed it to him, but alas! We two live in the two remotest parts of the world from each other! He lives in Argentina and I, in India. See, when we can meet!
