True or False: Contact lenses become cloudy during temperature changes.

The statement about contact lenses becoming cloudy due to temperature changes is false. Contact lenses are designed to maintain their clarity and performance across a range of temperatures. While extreme environmental conditions can affect some lens materials, generally, contact lenses are made from materials that are stable and do not become cloudy simply due to typical temperature variations.

It's also important to note that factors such as lens care and hygiene, as well as the accumulation of deposits or tears, can affect the clarity of lenses, but these are not directly related to temperature changes. The correct understanding is crucial for athletes and individuals who rely on contact lenses for vision, as clarity of vision is essential for performance and safety.
