Hi there

I am applying for a job where my unaided visual acuity needs to be
6/36 in my left eye and 6/24 in my right eye.  I know I have no
problem reading to 6/36 but I am concerned that I will not be able to
read to 6/24 (third line down on a British chart) unless have a small
squint very briefly.

I was wondering if squinting briefly in such a test is permissible or
if an optician would be reluctant to allow this in order for one to
read a little lower down the chart.

Any advice would be appreciated.
