Eye or face shield protection must be able to fasten securely, free of scratches, and able to allow clear views to both sides. Secure fastening is crucial for maintaining the shield's position during rides, preventing it from dislodging and exposing your eyes to potential hazards. Scratches can obstruct vision and may impair your ability to see clearly, posing a safety risk. Additionally, clear visibility to both sides is essential for awareness of your surroundings, including other vehicles, pedestrians, and obstacles, as you navigate the road. All these factors come together to ensure that your vision remains unobstructed and your safety is prioritized while riding.
