Dry eyes mimicking astigmatism

I recently went to an optometrist for the first time in 22 years for what I assumed was astigmatism. Apparently I don’t have astigmatism but my eyes are strained and dry and causing the same symptoms. I still have 20/20 vision but will start wearing glasses for when I’m using the computer and use eye drops 2-3 times per day. Anyone else dealing/dealt with this? Can I really expect improvement of the symptoms when my eyes are less strained and dry? TIA
