One stops chips. The other stops what a shattering wheel throws.
Verdict
Safety glasses are what you wear all day, and they stop the chips and dust that cause most shop eye injuries. A face shield covers the whole face and is what you add for grinding, turning and anything that could throw something substantial. Wear glasses always; add the shield for the grinder and the lathe, over the glasses rather than instead of them.

Every time you enter the shop. The injuries that end woodworking are usually not the dramatic ones: a chip in the eye from a router or a lathe is far more common and entirely preventable by glasses you actually wear, which means comfortable ones.

Hearing damage accumulates silently and does not recover. A router, planer or shop vac exceeds safe levels within minutes, and by the time you notice the loss it is permanent.

No, unless they are rated and have side protection. Over-glasses safety eyewear or prescription safety glasses are the two proper options.
They trap warm breath against a large plastic surface. Anti-fog coatings help, and so does a shield that stands further off the face. Fogging is why a shield is worn for specific operations rather than continuously.
Most guidance says wear glasses underneath, because a shield can be lifted or deflected and offers no protection from below. The two are complementary rather than alternatives.
