Question: What type of sunglasses should I be wearing to protect my eyes from ultraviolet light?
Answer: Well, it's important to wear sunglasses which have a good ultraviolet coating. Now most plastics will block ultraviolet light, but they may not be sufficient in a very bright situation. For this reason, it's also important that polarizing lenses be used. Polarizing lenses allow the reduction of glare without the need for excessively dark lenses, which oftentimes make it difficult to navigate.
