The old cliche: selling pencils and matches. So, why do blind people wear dark glasses? Here’s a website that refuses to get to the point:

Blind people wear sunglasses to protect their eyes from various environmental hazards, let people know they are blind, and protect what little vision they may have.

It is not uncommon for some people to wonder why many blind people wear sunglasses. Yet, very few people really know why that is the case. There are several reasons why so many blind people choose to wear sunglasses in many different environments. The decision to do so is always personal although it may be influenced by the opinions of those close to the blind person.

Some people assume that the main reason is an aesthetic one and, although that can be one of the main reasons, it is not always the case. Mostly, blind people wear sunglasses for a mixture of reasons.
