Drugstore glasses work for some people. They do not correct astigmatism. Astigmatism without correction can cause headaches also. If you have never had an eye exam, this might be a good time to have one. Optometrists and opthalmologists examine the inside of the eye during exams. Sometimes the eye shows the first evidence of some diseases. They can also fit lenses to correct nearsightedness or farsightedness. Most people plus or minus 40 years old need help to see well. I got my first pair of bifocals at 37. Of course I was farsighted to begin with.
