I read it on the internet so it must be true!   :)

Do you really think that all the makers of screens and lightbulbs are
risking making people go blind, with all the subsequent lawsuits for
damages?

You won't find evidence on sites selling special glasses. You just get
the sales spiel. Try reading reliable medical sites.
The main risk factors for age-related macular degeneration are Age
(!), smoking and family history (and being female).

On the other hand, special lenses will probably only damage your wallet.
