I have a rough patch on my cornea that developed over the past two months or so. It is like clear lumps on the white part under the iris. I am gradually beginning to have discomfort when wearing a contact lens on this eye. Could this be an infection or maybe irritation from the contact? I'm worried that treatment may involve switching to glasses, which will be difficult for me. I am a 54- y.o. female, 5'10" and 145#. I have worn soft contacts for 35 years, even sleeping in them every night, and never had an eye issue until the optometrist said I needed to switch brands to a type that would "breathe" better ...to the ones that are now hurting my eyes. Please help.
