No, clear lenses cannot be changed to transition lenses. Transition lenses have a special treatment that reacts to UV light to darken in sunlight, which cannot be added to regular clear lenses. You would need to purchase new transition lenses to have this feature.
Yes, there are sunglasses available with lenses that can transition from dark to clear when exposed to sunlight. These lenses are called photochromic or transition lenses, allowing you to wear your sunglasses indoors or at night as they adjust in darkness.
Yes, you can swim with transition lenses. However, prolonged exposure to chlorine or saltwater can damage the lenses over time. It's recommended to rinse the glasses with fresh water after swimming to help preserve the lenses.

Photochromatic lenses are commonly called transition lenses. The lens is clear, but when exposed to the sun's UV rays, they will darken like sunglasses.
Transition lenses are a type of eyeglass lenses that automatically darken when exposed to sunlight. They contain special photochromic molecules that react to UV light, causing the lenses to darken. When the UV light diminishes, such as when indoors, the lenses gradually return to their clear state. This allows the lenses to provide both vision correction and sun protection without the need to switch between regular glasses and sunglasses.
Freezing.
Transition lenses contain photochromic molecules that react to UV light. When exposed to sunlight, these molecules darken to protect the eyes from harmful UV rays. Indoors, where UV light is minimal, the molecules return to their clear state, allowing the lenses to lighten.
"Melting" and "freezing" are transition actions, going from solid-to-liquid form and liquid-to-solid form respectively. The point is the same transition temperature of that particular substance. The same goes for the transition temperature of the "boiling point" and "condensation point" of a substance.
The price of transitions lenses will depend both where one buys them and exactly what type of transitions lens. Most of the time transitions lenses cost between $25 and $50 though can be as high as $100.
Putting transition lenses in the freezer is not recommended. Extreme cold can damage the lens material and affect their ability to transition properly between clear and tinted states. Additionally, the rapid temperature change may cause stress or warping. It's best to follow the manufacturer's care instructions for optimal performance and longevity.
Condensation and freezing are both processes that involve a change in the state of matter. Condensation involves the transition of a gas to a liquid, while freezing involves the transition of a liquid to a solid. Both processes release heat energy as they change from a more disordered state to a more ordered state.
