How does an eyeglass lens differ from a magnifying glass lens?!
Question: If an old person can no longer read fine print, and gets glasses for that reason, are the lenses likely to be the same as magnifying glass lenses, or is there something fundamentally different about them?

magnifying lenses are usually convexed on both sides, where as glasses are concaved on one side only.
Nope they both magnify by refracting light waves.
Eyeglass lenses are curved so that they are convex on one side and concave on the other. They are also ground to a specific thickness and angle to match the wearers eyes and specific deficiency. They are also made from a high quality glass that has no distortions or imperfections. In contrast, your average magnifying glasses are made from much lesser quality glass and are simply convex on both sides and have no specific requirements regarding the user.
Best to see a specialist to get the right prescription.
People do not wear reading glasses because of their magnifying affect. They wear them to get rid of the blur.
If you have a blurred image and magnify it all you get is a larger blurred image. Eyeglass lenses have different curves than magnifying lenses.
