How to use: Simply put on the sunglasses. Adjust the nose piece for a comfortable fit. You can switch to the spare clear lens when needed, like in low - light conditions.
Things to note: Avoid scratching the lenses. Don't expose them to extreme heat or cold.
Maintenance advice: Clean the lenses with a soft, lint - free cloth. You can use a little lens cleaner, but make sure it's suitable for the Hydroilo coating. Keep the sunglasses in the provided case when not in use to prevent damage.
