The generic eyeglasses at the local store are reading glasses that are designed to be supplements for people with only very minor vision problems. They are not customized in any way, and these glasses may cause eye strain or even chronic headaches in some people. Anyone who has different prescriptions in each eye, anyone who has astigmatism, or anyone who has any serious degree of vision issues will do far better to get custom made eyeglasses that have their own unique prescription lenses. Prescription eyeglasses are also better because they require an examination. During the examination, the eye doctor will be able to look for emerging eye issues so that treatment can be started right away if necessary. The "silent" diseases, such as glaucoma, can be identified in their early stages during a vision exam.
A patient can rely on advice from their eye care providers when choosing the right frames. There are such a large variety of frames available today that something can be chosen to fit any person's facial structure and personal preferences.

Yes, photochromic lenses are an eyeglass and sunglass hybrid. These lenses will darken when they are exposed to UV light (typically, whenever a person is outside.) Once back indoors, the lenses will lighten to normal again. This is a great option for anyone who doesn't want to maintain separate prescription glasses and prescription eyeglasses.
