1. | 20 | = 745932 | 25 | = 578236 | 30 | = 346752 |
2. | 40 | = 534268 | 50 | = 752386 | 60 | = 6254 |
3. | 70 | = 8453 | 100 | = 85 | 200 | = 3 |
Proceed as on test #5 and #6.
To pass the acuity test, at least five of six characters must be read in Blocks A, Line 2 on each of the tests 5,6, and 7. This is a standard of 20/40 for each eye separately, and both eyes together. This standard corresponds to most State requirements. Business and industry may have more strict requirements which must be considered in establishing a pass/fail standard.
Test #8: Phoria
Actual Test
PHORIA
DOT INSIDE BOX
Ask your subject “Is the red dot inside or outside the yellow box?” If the dot is outside the box, a referral should be made.
(N.B.: Some subjects will see only the red dot or only the yellow box. This indicates they are using only one eye, either because the other is blind or “lazy” or because they have some other kind of “binocular vision problem”. In any case, unless the subject already knows he has such a defect, he/she should be referred for a full examination.)
