Question 1

Do I need to wear sunglasses even on cloudy days?

Accepted Answer

Absolutely! Up to 80% of the sun's UV rays can penetrate clouds. So, even on an overcast day here in Hanford, your eyes are still at risk.

Question 2

Can children get eye damage from UV rays?

Accepted Answer

Yes, and even more so than adults! Children's eyes are more susceptible to UV damage because their lenses are clearer and allow more UV light to reach the retina. Protecting their eyes from a young age is vital for their lifelong vision health.

Question 3

What about UV exposure from reflections?

Accepted Answer

Reflective surfaces like water, sand, snow, and even pavement can significantly increase your UV exposure. For example, snow can reflect up to 80% of UV radiation, effectively doubling your exposure. This is particularly important for those enjoying our local parks or the beautiful California coast.

Question 4

How can I tell if my sunglasses offer enough UV protection?

Accepted Answer

Look for sunglasses that block 99-100% of both UVA and UVB rays, or those labeled "UV400." This means they block light rays with wavelengths up to 400 nanometers, providing comprehensive UV protection.

Question 5

Are expensive sunglasses always better for UV protection?

Accepted Answer

Not necessarily. The price of sunglasses does not always correlate with their UV protection capabilities. Many affordable options offer excellent UV blocking. The key is to check the label for the specific UV protection rating, not just the brand name.
