Don,
This topic has come up from time to time in the J-STD-001 and IPC-A-610 
committee meetings.  Vision is usually assumed to be corrected to 20/20 
and you go from there.  Several individuals in the committees, who deal 
more with oversees usage of A-610 indicate that "20/20" or "3 diopters", 
are American terms and have no meaning oversees.  I confirmed that with my 
brother-in-law, a doctor of optometry, who confirmed that there is no 
international standard for visual acuity.

Subject
[TN] Should inspectors be able to see?






Does anyone have a standard for an inspector's ability to see? We have 
required them to pass color-blind testing in the past, but have recently 
mulled over a visual acuity requirement. I wondered if this is more normal 
than not, because it seems like we would want to ensure that they see 
lines with definition rather than blurry masses. 

I humbly look forward to any input that may be offered. 

Don
