Hello everybody!
This morning, I was asking me if the snellen test cards that we can find on internet and print on a letter-format sheet are accurate.
I saw that the corresponding letter on differents charts are not always the same size.
I personally use this one:
<!-- m --><a class="postlink" href="http://www.disabled-world.com/artman/publish/eye-chart.shtml">http://www.disabled-world.com/artman/pu ... hart.shtml</a><!-- m -->
But the one on this page have smaller letters:
<!-- m --><a class="postlink" href="http://www.central-fixation.com/resources.php">http://www.central-fixation.com/resources.php</a><!-- m -->
And this one seems okay with the one I use:
<!-- m --><a class="postlink" href="http://www.i-see.org/eyecharts.html">http://www.i-see.org/eyecharts.html</a><!-- m -->
So, does someone here buyed a ''true'' snellen test card? And can you tell me what snellen is the most accurate with a true chart?
What snellen eye chart did you use?
Have a nice day!
