The correct answer is B. Wearing sunglasses all year long is important because they block the harmful UV rays that come from the sun. UV rays are a type of radiation emitted by the sun that can be damaging to your eyes and skin.
To understand the importance of wearing sunglasses, we need to understand UV rays. UV rays are classified into three types - UVA, UVB, and UVC. UVC rays are absorbed by the atmosphere and do not reach the Earth's surface. However, both UVA and UVB rays can have harmful effects on our eyes and skin.
When we are exposed to excessive UV radiation, it can lead to several eye conditions such as cataracts, macular degeneration, and even cancer of the eyelids. UV rays can also cause damage to the sensitive skin around our eyes, leading to premature aging and wrinkles.
By wearing sunglasses that are designed to block both UVA and UVB rays, you can significantly reduce your eye's exposure to harmful radiation. Sunglasses with UV protection help to shield your eyes and the surrounding area from the harmful effects of UV rays.
It is important to note that wearing sunglasses is not just necessary during sunny days or in the summer. UV rays can still reach your eyes even on cloudy or overcast days. They can also reflect off surfaces such as water, snow, and sand, increasing your exposure. Therefore, wearing sunglasses all year long, even during winter or when the sun is not as bright, is essential for protecting your eyes from UV damage.
When choosing sunglasses, opt for ones that provide 100% UV protection. Look for labels or stickers that indicate they block both UVA and UVB rays. Additionally, larger sunglasses or wraparound styles can offer better coverage and protection by reducing the amount of peripheral light that enters your eyes.
In conclusion, wearing sunglasses all year long is crucial because they block the harmful UV rays that come from the sun. By protecting your eyes from UV radiation, you can reduce the risk of eye conditions and keep your eyes healthy.
