Gecko Vision: Key to Future Multifocal contact lenses?

Nocturnal Geckos are some of the only animals who are able to see colors at nighttime. Scientists hope to use the eyes of the Geckos to create better cameras and contact lenses. Geckos differ from other vertebrates in that they have only cones in their retina. They have a multifocal optical system that allows different ranges of light wavelengths to focus simultaneously on the retina. Their eyes allow them to focus on objects at different distances. According to the article, the multifocal eye would generate a sharp image for at least two different depths. This will help increase the quality of a camera lens as well as useful multifocal contact lenses
