Many people have eyesight conditions which require corrective glasses, such as eyeglasses and contact lenses.
Optometric services can be difficult to obtain in remote places.
Travellers with daily need of corrective glasses could need to carry a spare pair. For sport and other activities, contact lenses might be more practical than wearing glasses.

Sunglasses are a classic among tourist accessories, especially to tropical, maritime and snow resorts, to prevent ultraviolet keratitis (snowblindness).
As sunglasses are easily lost or damaged, think twice before packing an expensive designer model.
Excessive wearing of sunglasses (indoors or in cloudy weather) could be regarded as bad manners.

Eyeglasses can be cheaper in a foreign country, sufficient to pay for a journey. This also applies to surgery to treat myopia; see medical tourism.
