Adjustable focus eyeglasses are eyeglasses with an adjustable focal length. They compensate for refractive errors (such as presbyopia) by providing variable focusing, allowing users to adjust them for desired distance or prescription, or both.
A corrective lens is a transmissive optical device that is worn on the eye to improve visual perception. The most common use is to treat refractive errors: myopia, hypermetropia, astigmatism, and presbyopia. Glasses or "spectacles" are worn on the face a short distance in front of the eye.
Example of a situation where glare can be problematic, if, for instance, the ability to determine the distance and speed of passing cars is reduced. Glare can reduce visibility by: Reduction of brightness of the rest of the scene by constriction of the pupils
Progressive lenses (those that function as both reading and distance glasses) start at $295, while tinted prescription lenses cost an additional $100 from the base model.
In transport, driver visibility is the maximum distance at which the driver of a vehicle can see and identify prominent objects around the vehicle. Visibility is primarily determined by weather conditions (see visibility) and by a vehicle's design.
Vertex distance is the distance between the back surface of a corrective lens, i.e. glasses (spectacles) or contact lenses, and the front of the cornea.
