What are the advantages and Disadvantages of Thermochromic materials?

Answer 1

Advantages of thermochromic materials, otherwise known as transition lenses, include the convenience of not having to switch to prescription sunglasses. A disadvantage would be not transitioning completely to a transparent state, or being too opaque.

Answer 2

Well, darling, thermochromic materials have the advantage of changing color with temperature, making them great for mood rings and novelty items. On the flip side, these materials can be finicky and lose their color-changing properties over time, which is about as fun as a root canal. So, use them wisely, honey, and don't expect them to last forever.
