Provided are systems and methods to temporarily alter visual acuity of a subject. An example system includes a first light source configured to produce infrared light in an infrared wavelength spectrum for transient propagation into an eye of the subject and a second light source configured to produce visible light in a visible wavelength spectrum for transient propagation into the eye of the subject. The system further includes a transmission unit configured to propagate the infrared light and the visible light into the eye, wherein the light propagated into the eye temporarily alters visual acuity of the subject.

Systems and methods for altering visual acuity

Provided are systems operable to effect a temporary change in a modulation transfer function (MTF) of a target imaging system. The systems include a light source operable to produce light for transient propagation onto at least a portion of the target imaging system, a power source in operative communication with the light source and configured to effect the production of light from the light source, and a transmission unit in operative communication with the light source and configured to propagate the produced light onto at least a portion of the target imaging system. The propagated light is configured for absorbance by the portion of the target imaging system; the absorbance causes an increase in temperature and a change in a refractive index profile of at least the portion of the imaging system. The change in refractive index profile produces a temporary change in the MTF of the imaging system.
