Color blindness

My 9 year old son sees some shades of light blue as white, should I be concerned?  He passes the basic Ishihara color blindness test, and can see dark shades of blue correctly.  I am just wondering if I should take him to be evaluated at clinic that can do more testing than a regular eye doctor's office.

Thanks,

If he passes the ishihara test and has excellent vision then you may not have anything to worry about as far as color vision.  But if he hasn't seen an ophthalmologist then he needs to.  So I recommend a  complete evaluation with an ophthalmologist.
