Final answer:
Goggles offer the best protection for the face and eyes while riding, as they provide secure fit and cover against various hazards, including UV radiation. Reading glasses and sunglasses do not offer adequate protection in such scenarios.
Step-by-step explanation:
Of the options given for riding, goggles provide the best face and eye protection. While sunglasses may offer some protection against ultraviolet radiation and are better than no protection at all, they do not typically provide full coverage. Reading glasses would not be designed for protection in activities such as riding. Goggles offer a more secure fit and comprehensive protection against wind, dust, debris, and light that may enter from the sides, which is important while riding fast or in areas with lots of particulates in the air.
Moreover, it's crucial to use protection that blocks UV radiation effectively. Materials like polycarbonate used in many goggles not only protect against mechanical injuries but also block most harmful UV rays. For looking directly at the Sun, activities such as solar observation or viewing an eclipse, it is critical to use specially designed safe filters like welders' goggles or eclipse glasses to prevent retinal damage. Ordinary sunglasses or homemade filters are unsafe for this purpose because they can transmit infrared radiation that causes severe damage to the eyes.
In any activity that poses a risk to eye safety, such as riding, appropriate protective eyewear should be used. For individuals who partake in activities with risks of impact or exposure to harmful rays, such as recreational riding, working with dangerous equipment, or observation of solar events, the use of proper protective eyewear like safety goggles is important for maintaining long-term eye health.
