You can get malignant melanoma in your eyes.

My dad was recently diagnosed with malignant melanoma from a secondary tumour that grew in a lymph gland in his neck.

When they were searching for the primary site (which they never found in the end) one of the places they looked was in his eyes. I never even knew you could get melanoma there! He was advised that one of the best precautions people could take was to wear sunglasses.

It is rare to get melanoma in your eyes but please protect them - wear good sunglasses.
