Human: Should people with light colored eyes (especially blue) wear sunglasses on bright days?

Assistant: Light-colored eyes, especially blue, are less well-suited to filter dangerous UV radiation from sunlight than darker-colored eyes.  Because of this, it is generally a good idea for people with light-colored eyes to wear sunglasses when going outside on bright days, to protect themselves from UV damage.  Otherwise, the bright light can cause eye irritation, as well as potentially causing long-term eye damage and vision issues.

Assistant: This is an interesting question, and the answer is not 100% clear.  There is certainly some statistical evidence that eye color affects the possibility of retinal damage from the sun, so blue-eyed people do need to be especially careful and should strongly consider wearing sunglasses when they’re going to be out in the sun for extended periods of time.  However, this doesn’t meant that they need to always wear sunglasses, since sunglasses can also cause significant glare issues and halos that can cause more harm than the light directly.  In general, you should always use sunscreen, try to stay out of the sun during the hottest hours of the day, and especially be careful with extended outdoor activities or around water.
