Harry Potter fans are so desperate to look like their wizard hero, they've sparked a dramatic increase in spectacle sales.

Opticians across the UK are preparing for sales to double again between now (NOV05) and January (06), as young fans flock to see the fourth movie HARRY POTTER AND THE GOBLET OF FIRE.

Daniel Radcliffe, who plays the boy wizard, says, "Harry Potter has managed to make specs cool again and struck a blow for anyone who's ever been teased about it or called four eyes."
