There are many types of sunglasses. Some have a reflective lens like a mirror while others just have a dark shade. There are sunglasses which become darker when sunlight is stronger and lighter when sunlight is weaker. The lens can be made from different materials too such as glass, plastic, crystal, etc. What kind of sunglasses do you wear? What colour are the lens?
I've got the ones that changes shade depending on sunlight which is cool cos mine are prescriptions lenses as well which means i dnt have to wear contacts
