They idea of replaceable lens is already there so I will not really give any points for creativity. However, they have created a much more stylish option that is viable in the magnetic system. They also have a much more sleek design of the glasses (very minimal).

There is nothing on their page that shows they are specifically environmentally responsible. However, their system certainly will reduce the amount of plastic needed for sunglasses. The lens themselves are using glass and metal which are more environmentally friendly.

The benefits of this project is the stylishness of the lens and the unified look of all the lens using the same magnetic system. There already exists the clip on lens which is much more inexpensive. Therefore I would say the benefits and costs are about the same and so cancel each other out.

Neat idea to avoid needing to swap multiple glasses or using the flip hybrid ones

No mention in campaign

Could be nice value for the select group that needs multiple glasses/lenses
