So I apparently have an eye infection

When I was in my optometrist's office for my vision check up, I was hit with some startling news. I had an infection in my eye that was masked by my contacts; apparently half of my left eye was a red cornea. So yeah, as a result, I have to go contactless for a week, and I need to put this fancy eye drop medicine into both eyes four times a day for at least a week; I have my follow up appointment in a week to see if my eyes are not infected anymore.And to add some more insult to the proverbial injury, the vision in my right eye got worse AND the medicine, which basically is a ridiculously small bottle of eye drop, costed around $65. Ouch.
