I am a 22 yr old female. I wear contact lenses daily and have never had an infection or issues with my eyes (apart from myopia). Within the last few months, I have been feeling irritation when I wear my lenses. (It is not due to old lenses as I have changed them and I have tried changing my cleaning solution as well to no avail). I have also tried eye drops and "contact rewetting drops", and those did not help either. After a couple hours, they become painful to the point that I can hardly keep my eyes open, burn and the contacts feel like foreign objects. My eyes become bloodshot as well but they are not as red as they are painful! Also, recently even when I don't wear my contacts I am very light-sensitive and sometimes continuously tear in daytime light. What could this all mean?
