Dogs have eyes as sensitive as humans eyes and can be injured if not protected.
It is important to protect pets eyes from harmful UV rays as well as during other outside activities.
For example, hiking can cause danger to dogs running through low hanging branches which can pose an injury to eyes, or flying debris on a windy day.
You want to protect pets eyes even in the winter when the sun glare bounce off the snow. It can cause snow blindness in dogs and humans.
Sunglasses made specifically for pets fit well and hold on with elastic strap around the head. Wearing sunshades will protect pets eyes from the sun glare, UV, eye dryness or cataracts.
