Slight colour blindness??

I struggle when reading the colour red; it kinda goes blurry and just now i was doing a sudoku puzzle where the lines that indicate each block of 3x3 were red but the other lines were black and i really struggled to work out where each set of 3x3 started and finished. Im not colour blind according to the tests (iv tried several) so whats wrong with me? i wear glasses fr short sightedness and they do help. (eg. when a tutor writes in red on a white board now i can work out what it says whereas before it was just squiggles). The best way i can explain it is this:
(without glasses)
at 2 metres from a whiteboard i could probably read text if it was black (depending on size) but if the text was red it would be blurry.
at 5 metres from the board both coloured texts would be blurry but the red more so.

Sorry if this is a bit garbled, I have tried to make it as clear as possible.

The human eye is less sensitive to red than to colours like green.

I didn't know that until a lecturer commented on it, but it makes a whole lot of sense.

Is your dad colorblind?

For females to be colorblind, her dad has to be while her mother is a carrier of the recessive gene.

Asking dad now!!

get a new optician.
They are generally really good they told my uncle to go to the doctors when there was something wrong with his eye and it turned out that if it hadn't have been spotted it could have made him blind so they are normally really good and professional

So im not the only one who struggles reading red?? At school/college no-one else seemed to have a problem when the teacher wrote in red.

I have trouble reading bright green in lectures. Most people that sit by me do. Perhaps red and green are just icky colours that are a little tricky to see. I also have problems with dark orange sometimes as well. It seems that it goes blurry quicker than other colours. Just get some glasses and it'll improve (it does for me).

No your not, like i say when i was at school and just before i started wearing glasses, i found it harder to read red writing on the white board and alot easier to read black

I'm told my brother can't see red, he sees it as brown , the smae with other similar colours. I'd still ask for a test, they might be able to give you coulored film to read through, my brother uses yellow as apparently it helps him see better (?!)
