For many people, contact lenses are a convenient alternative to glasses. They provide a wider field of vision, don't fog up in cold weather, and allow people to wear sunglasses without prescription lenses. Yet millions of people who could wear contacts choose not to. Some try them once and never use them again. Others stick with glasses for years, even when friends encourage them to switch. It's easy to assume they're simply afraid of touching their eyes or resistant to change. Psychology suggests the explanation is often more complex.
People differ in how they respond to physical sensations, uncertainty, habits, and perceived control. For some individuals, contact lenses simply don't feel as comfortable or predictable as glasses.
