Left eye pain. Suggest what should i do?

Hi, i am a working professional. I had undergone a intralase lasik surgery around 8 years back and everything was fine without any issues. However since the lockdown, due to lack of sleep and constant working from home using a laptop, for the last 10 dats i am experiencing pain in my eyes. Especially my left eye is quite painful and im having blurry vision. Can you suggest what should i do? I have tried limiting using laptop watching tv or using phone, however today the pain in my left is really unvearable, its also leading to a pain on left side if face and head. Another main problem is i am unable to sleep more thanna max of 3-4 hrs in a day. What should i do for this pain and sleeplessness. NOTE: my work is usually during night shifts(5pm to 4am)
