Hello,
Thank you for asking the query.
I understand that you are looking for a quick and temporary solution for your problem.
Before coming to that let me tell you that getting a proper correction for your refractory error is the best solution. You eye power might have gone up or down. Also astigmatism should be ruled out. I recommend consulting an ophthalmologist as soon as possible in this regard.
Now for temporary and quick relief, I suggest the following:
1.You can use an over the counter analgesic/ pain reliever occasionally. Tylenol or Paracetamol 500mg are some options. Take 1 tablet immediately if you get pain. You can take upto 3 tablets per day.
2.Eye drops are going to be of no help.
3. While reading take breaks. If you read for 15 minutes continuously, close your eyes for 1-2 minutes. Then open look towards and focus on a distant object for a couple of minutes. Then continue reading. REPEAT
4. You can also try keeping ice cubes over the face for pain relief.
Hope this helps.
