Google Contact Lens

Google Contact Lens is a smart contact lens project announced by Google on 16 January 2014. The project aims to assist people with diabetes by constantly measuring the glucose levels in their tears. The project is being carried out by Verily and it is currently being tested using prototypes.==Design==The lens consists of a wireless chip and a miniaturized glucose sensor. A tiny pinhole in the lens allows for tear fluid to seep into the sensor to measure blood sugar levels. Both of the sensors are... read more

However, to find a photographic lens equivalent to the human eye, which has an effective focal length of approximately 17mm,Pocock, Gillian & Richards, Christopher D & Richards, Dave A (2013).

Telephoto lens

In and , a telephoto lens is a specific type of a in which the physical length of the lens is shorter than the . This is achieved by incorporating a special lens group known as a ''telephoto group'' that extends the light path to create a long-focus lens in a much shorter overall design. The and other are the same for telephoto lenses of the same specified focal length. Long-focal-length lenses are often informally referred to as ''telephoto lenses'' although this is technically incorrect: a... read more

Typically, one element is a negative () element made out of such as F2, which has relatively high dispersion, and the other is a positive () element made of such as BK7,... read more

Lens flare

Lens flare is the light scattered in systems through generally unwanted image formation mechanisms, such as internal and from material inhomogeneities in the lens. These mechanisms differ from the intended image formation mechanism that depends on refraction of the image rays. Flare manifests itself in two ways: as visible artifacts, and as a haze across the image. The haze makes the image look "washed out" by reducing contrast and color saturation (adding light to dark image regions, and adding... read more
