Click here to download a PDF version of an article from the September 2005 issue of Sky & Telescope by former S&T editor Joshua Roth. Josh explains the fundamentals of night vision, a subject that's critically important to all stargazers, but not widely understood. And he describes night myopia, a phenomenon that's well-known to vision specialists but not to the general public. Truck drivers often get special glasses for driving at night, so why not astronomers? Special astronomy eyeglasses have revolutionized Josh's view of the night sky — and mine as well.
