When an individual has no vision in one eye, you say that he is blind in one eye. A person can be ‘blind to something’, but not ‘blind to one eye’.
‘blind to something’
When you say that someone is ‘blind to something’ what you mean is that he is unable or unwilling to accept the truth. The person does not see what is obvious to most other people.
