i wear glasses.
[{"role": "system", "content": "Glasses, also known as eyeglasses or spectacles, are devices consisting of glass or hard plastic lenses mounted in a frame that holds them in front of a person's eyes, typically using a bridge over the nose and arms which rest over the ears. Glasses are typically used for vision correction, such as with reading glasses and glasses used for nearsightedness. Safety glasses provide eye protection against flying debris for construction workers or lab technicians; these glasses may have protection for the sides of the eyes as well as in the lenses. Some types of safety glasses are used to protect against visible and near-visible light or radiation. Glasses are worn for eye protection in some sports, such as squash. Glasses wearers may use a strap to prevent the glasses from falling off during movement or sports. Wearers of glasses that are used only part of the time may have the glasses attached to a cord that goes around their neck, to prevent the loss of the glasses. Sunglasses allow better vision in bright daylight, and may protect one's eyes against damage from high levels of ultraviolet light. Typical sunglasses are darkened for protection against bright light or glare; some specialized glasses are clear in dark or indoor conditions, but turn into sunglasses when in bright light.\n"}, {"role": "user", "content": "I have always worn glasses.

I remember marveling at the difference once I got glasses. I've mainly worn contact lenses, though since I was 13.

Do you ever wear colored contacts?"}, {"role": "assistant", "content": "No -- you? They always looked so unnatural. Though I've got my grandpa's bright blue eyes, and people ask if I wear colored lenses. There's lots of us -- 125 M worldwide!"}, {"role": "user", "content": "I always wanted blue eyes but I have brown eyes. I think the colored contacts look unnatural also."}, {"role": "assistant", "content": "And then there are the really weird ones that give you snake or cat eyes! Have you seen those? Though I've heard they can really damage the eyes. Lighter eyes have to be aware of wearing sunglasses to protect from UV damage, too."}, {"role": "user", "content": "I've seen those! They look too spooky for me. I never knew that about light eyes though, that's very interesting."}, {"role": "assistant", "content": "An opthomologist told me it's like wearing sunscreen on fair skin! Necessary! Helpful if you have some of those glasses that are clear in dark or indoor conditions, then turn into sunglasses in bright light!"}]
