Contact Lens - English Definition & Meaning

Definition

A 'contact lens' is a thin, curved lens placed on the surface of the eye to correct vision. It's a discreet alternative to glasses. Think of it as a tiny, personalized screen for your eye. Contact lenses come in various types, including daily disposables and extended-wear lenses. They can correct nearsightedness, farsightedness, and astigmatism. Some people wear them for cosmetic reasons, changing their eye color. They require proper care and hygiene to prevent infection. It's like a personalized vision upgrade.

Etymology

The concept of contact lenses dates back to Leonardo da Vinci in the 16th century, who sketched ideas for altering corneal power. However, the first practical contact lenses were developed in the late 19th century. The term 'contact lens' is a straightforward description of its function: a lens that makes 'contact' with the eye.
