Are you prepared for your Bcva Examiner Training and Certification? This quiz may be of assistance. This quiz involves knowing the purpose of conducting trial-frame refraction and the visual acuity score. Also, what type of lens is added to accommodate testing at one meter, the Snellen Equivalent, and the best method of occluding the eye that is not tested on See moreemployees. This quiz will help you see how much you can learn.

Rate this question:
The VAE should test the subject for count fingers
The VAE should stop the test at 4M and move the subject to 1M
The VAE should attempt to test the patient on line 2 at 4M
The VAE should stop testing and write N/A for 1M testing
Rate this question:
The subject has received a Visual Acuity Score greater than ‘0’
The subject has been able to read letters at the 4M and/or the 1M distance
If the subject has a Snellen Equivalent score of 20/200
All of the above
Rate this question:
The subject has received a Visual Acuity Score of ‘0’
The subject has not been able to read any letters at 4M and at 1M
The subject has a Snellen Equivalent of 20/NA
All of the above
Rate this question:
+/- 0.25 sphere
-0.37 lens
+0.75 sphere
Jackson Cross cylinder lens
Rate this question:
If the subject reads 3 or fewer letters on Line 1 at 4M, move the subject to 1M for both refraction and testing
The Genentech VA stopping rule is once 3 or fewer letters are read correctly on any row, STOP testing on that row.
The Snellen Equivalent is the most difficult line read with a score of 4 or 5
The Genentech VA stopping rule is to continue testing the subject until he/she gets a score of ‘0’
Rate this question:

Rate this question:
Low Vision Testing should be conducted on all subjects who have a Snellen Equivalent of 20/500 or worse
Testing should be stopped once the subject reads 3 or fewer letters and a vertical line needs to be drawn through the remaining spaces not tested
The subject is only tested at 1M if 3 or fewer letters are read at the 4M distance
If the subject reads 4 to 5 letters at 4M, continue testing until the subject can only read 3 or less letters on any line
