You should clean and maintain your shooting glasses regularly to keep them in good condition and performance. For example, you should wipe your lenses with a soft cloth or a lens cleaner after each use to remove dust, fingerprints, or smudges. You should also store your glasses in a case or a bag when not in use to protect them from scratches or damage. You should also inspect your glasses periodically for any signs of wear or tear and replace them if necessary.
