My eyes hurt when the sun is very bright and hot, especially at noon and during summer. Because of this, I make sure my Costa Del Mar Sunglasses are inside my bag so I can stay protected from the sun anywhere I go. I even have spare sunglasses in my car so I can grab it easily as I drive during a hot summer day. I soo love Costa del mar sunglasses because they are stylish and very dependable. No wonder I have five pairs of it!
