There are no optometrists on these forums. This is a MD ophthalmology forum.
I would recommend that you seek the care of an eyeMD to obtain your prescription. Have your eyes checked undilated as well as dilated, known as a cycloplegic refraction. If you are on your computer and doing a lot of near tasks, it is possible your muscles are still working during the examination. Also, while doing near work on a computer, texting or reading, try to take frequent breaks by focusing across the room at an object once every hour.
