Kelly, Yes, your eyes are going to be OK. I have variable vision regularly. It may take a half an hour for my vision to settle down in the morning.

The back of the eyes is not where a lot of scary concussion issues show up except right away from a severe jarring forward. They do not slowly develop and show up months later.

My eyes are dry depending on the time of the day and whether I am hydrated. I have moistening drops on my night stand because some mornings my eyes are miserable until I add some moisture.

But, none of these issues are worth any worry.

A little need for reading glasses as we get to our 40's is not uncommon. Many buy cheap readers at the drug store or even dollar store. They sell them by power. 1.25 is the weakest and 2 or even 2.5 for people with serious presbyopia. You would be best to avoid using them unless your eyes are tired so your eye muscles get some exercise.
