eye mets

Hello everyone, I was wondering if anyone has experience with eye mets? And if so what were your symptoms, if any? My sister is having trouble with her eyes, they look very red and irritated and they are sore. She is having trouble with her contacts, her vision has been blurred with them on, it's a little better with her glasses. If anyone has any info or experience you could share I would greatly appreciate it! Thanks, Jennifer in Colorado
