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 or perhaps, if it will be cheaper there, buy another pair at the destination. 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).
Sunglasses come at very different price levels, with the simplest models sold at corner shops for a token cost. Polarizing sunglasses filter reflections, which is especially useful on snow and at sea.
As sunglasses are easily lost or damaged, think twice before packing an expensive designer model. Regardless, check that the glasses really protect your eyes. If they are better at filtering visible light than at filtering UV radiation, they will increase the risk of keratitis rather than help.
Excessive wearing of sunglasses (indoors or in cloudy weather) could be regarded as bad manners, and a giveaway for being a careless tourist.
Eye care tourismEdit
Eyeglasses can be cheaper in a foreign country, especially in low-income countries where labour costs are lower. Consider getting an eye exam at home, especially if insurance covers it, and bringing the prescription along to be filed elsewhere. High-end brand-name frames available in such areas may have two problems; some may be knock-offs, and the real imported ones may be more expensive than at home.
Eye surgery — in particular common procedures like cataract surgery or laser eye surgery — may also be cheaper; see medical tourism.
Solar eclipse viewingEdit

When going to watch a solar eclipse, you must wear special kinds of glasses because the brightness of the sun, when you look directly at it, can be bad for your eyes.
