#27 Optics Tip: Protect the Eyepiece

Most good binoculars come with an eyepiece cap, also known as a rain-guard. You should immediately attach this rain-guard to the left neck strap and let it hang there, so that it will always be available to quickly fit over the eyecups, and protect the eyepiece when out birding.


This is especially handy if it rains, or the wind whips up fine particles of sand, or if you happen to be eating a sandwich!
