The Sun can be safely viewed at any time using these techniques. Note that the Sun is the only celestial object that CANNOT be viewed safely with the naked eye. It is always safe to view the Moon, the stars, and the planets with the naked eye.Â

Is it Safe to Clean Eclipse Glasses and Handheld Solar Viewers?
Manufacturers of hard plastic eclipse glasses often supply a microfiber pouch that you may use to wipe the lenses clean. The same pouch may be used on the lenses of cardboard eclipse glasses and handheld solar viewers. You may also wipe them clean with any soft, nonabrasive tissue or cloth; Kimwipes are also suitable, but baby wipes and other wet wipes are not suitable. The cardboard must be kept dry; if it gets wet, it will swell and likely detach from the lenses. Do not use water, glass cleaner, or any other solvents or liquids to clean cardboard eclipse glasses and handheld solar viewers.
