What could be causing excessive tear shedding and eye pain?

Hi doctor,

I am having a pain in my right eye that causes my eyes to excessively shed tears as well as causing a slight pain and discomfort. It started almost three to four days ago. I changed my medical lenses, and I changed the solution. I put them in almost every day. I noticed my symptoms temporarily disappeared the day I wore the new lenses, but they reoccurred the next day. It is worth mentioning that my sleep pattern is slightly disrupted (meaning I sleep three to four hours in the early morning, then again another three to four hours in the afternoon). Also, I spend almost my entire day staring at my laptop screen, as this is one job requirement. By the way, I tried artificial cleansing tears and eyedrops, and they almost had no effect.

To clarify, I am taking hand washing seriously, and I wash my hands with soap before touching my lenses and eyes.

Please advice me about the best solution.

Thank you.
