    • Different people will have different sensitivities to mould. With that said, it is likely that mould would affect someone’s eyes if they were sensitive to it. The mould spores would have to get in the eyes from being airborne or having direct contact with the mould. If you feel you are having a reaction from mould in your eyes, or any part of you, you should consult a physician without delay.
