Isn't 'guidance' different from 'regulation' though? In my previous profession, if you had good reason to deviate from guidance then nothing to stop you, you just had to be able to justify it if required. The TOCs just choose not to?

Highest number so R +4.50 and L +5.50 If adding them together gave you a higher number you'd go by that.

Your worst eye is +6.00 max, your other is +1.50 max. You are looking for the highest number. In your case, adding them together gives a lower number.

Maximum combined. Add them together, but watch for + and -. eg. -5.00/+200x180 has max of -5, -5.00/-2.00x180 has max of -7 Edit... oops... sorry highest number you get, and you might have to add them together.

Incorrect. The test allows a colour vision deficiency to be recorded as mild or strong deuteranopia or protanopia. But yes, it's use in the railway is pass or fail I believe.

The Ishihara test IS a red-green deficiency test. It can determine whether a person has total colour blindness, or mild or strong red or green deficiencies.

Someone posted a link with the requirements... https://www.rssb.co.uk/rgs/standards/RIS-3451-TOM%20Iss%201.pdf Page 17

This was answered in one of your other threads!

I would think the maximum combined power would be used as a prescription can be written in + or - cyl form. +5.25/-3.50x180 and +1.75/+3.50x90 are exactly the same prescription.
