Changing lens shape is one thing, but it's also possible to just directly change the index of refraction of the material with any moving parts.

- IronyMan42 6y agoHow do you do that, i thought this is a property of the material itself?
- baybal2 6y agoThere are materials in which refractive index can be changed significantly by electric field/temperature/mechanical strain
