All professionally run shooting grounds/schools insist on all attendees wearing shooting safety glasses. They are of course a mandatory requirement at all registered clay shooting competitions.
Choosing the shooting glasses.
Your shooting coach and retailing specialists will best advise you; but you need to carry out quite a lot of research yourself before you make that all important purchase.
This is actually quite difficult because you can hardly walk into your local friendly gun shop and ask to borrow half a dozen different types for a few weeks at various clay shoots.
Just like choosing your first gun, you will need to take advantage of the kindness and generosity of your new experienced clay shooting friends, who will lend you their different types of glasses for you to experiment with in a variety of light conditions and topographies.
