Are People Who Wear Glasses Smarter?

Does wearing glasses make you smarter?

Some studies say that it’s true.

But the relationship between glasses and intelligence is unclear.

One proposed theory is that damage to the occipital lobe in the brain may cause an overcompensation in the logic centre in the frontal lobe. But the evidence is hazy. In fact, there is little around, surprisingly. Theories on the origins of this association are varied but unsubstantiated. One possible idea is that more people need glasses than have them, and those that do wear them function better. One idea for the etymology of the smart specs wearing archetype is that when glasses first appeared few people had them, and those that did needed them to read. Other people who needed glasses but didn’t read wouldn’t have had them, so the bookish glasses-wearer is an ingrained stereotype.
