THis is going to sound strange but forgive me for this naive question, since I haven't needed any glasses for anything in life, except for sunglasses. But my luck may run out soon going into the 5th decade of life.. I am noticing it's just more difficult to thread a sewing hand needle when I need to alter clothing. And I used to be a regular sewer..before cycling, so I knew how sharp my vision was for many hrs. under those circumstances.

I always thought it was safest to have one's vision tested first before figuring out prescription vs. non-prescription route.
