Nature has inspired humanity in many ways. A whole new field of biomimicry has now evolved, which deals with nature inspired techniques to address many of our challenges. Now, a new study inspired by the eye structure of trilobites -- sea creatures known to be extinct since the age of dinosaurs -- has discovered a novel method of lens fabrication that can ward off spherical aberration. The scientists have fabricated these lenses based on the shape of trilobites’ eyes which are unique and are not adjustable. These lenses, the scientists say, have superior optical performance and find use in a range of optical applications.
