Bioptics (device) Bioptics, also known as a bioptic in the singular, and sometimes more formally termed a bioptic telescope, is a term for a pair of vision -enhancement lenses. They magnify between two and six times, and are used to improve distance vision for those with severely impaired eyesight, especially those with albinism.
Unlike a telescope which would be hand-held, the implant moves with the eye which is the main advantage. Patients using the device may however still need glasses for optimal vision and for close work. Before surgery, patients should first try out a hand-held telescope to see if they would benefit from image enlargement.

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.
Adaptive optics ( AO) is a technique of precisely deforming a mirror in order to compensate for light distortion. It is used in astronomical telescopes [ 1] and laser communication systems to remove the effects of atmospheric distortion, in microscopy, [ 2] optical fabrication [ 3] and in retinal imaging systems [ 4] to reduce optical aberrations.
