The invention relates to cylindrical tunable fluidic lenses. The cylindrical optical power of the lenses may be continuously tuned within at least ±10 diopters, without inducing any significant spherical aberration, or any other significant aberrations. The lenses feature a geometry that produces minimal or no spherical defocus. These cylindrical tunable fluidic lenses could be used to induce and/or correct cylindrical optical aberrations in adaptive optical systems, particularly in ophthalmologic applications related to objective and automatic assessment of the refractive error of the eye, without the need of receiving feedback from the subjects.

Systems and methods herein describe a prescription system for flexible lenses. The prescription system receives a current state of a pair of flexible lenses of a pair of eyeglasses, causes presentation of one or more images on a graphical user interface displayed on the lenses, receives audio feedback relating to the one or more images from a wearer of the eyeglasses, based on the feedback, sends an instruction to cause an air pump affixed to the eyeglasses to inflate one or more compartments of the pair of lenses, in response to the instruction, receives an updated state of the pair of flexible lenses, and generates prescription data for the pair of lenses based on the updated state of the pair of lenses.

Disclosed is a computer-implemented method for assessing suitability between an optical device and its user, the optical device including an optical lens placed in front of an eye of the user when the user uses the optical device, the optical lens having a plurality of optical zones having different optical functions, the method including at least the following steps: a requesting step, during which the user, equipped with the optical device, is requested to use the optical device in a plurality of different visual situations, each visual situation being associated with an optical zone of the optical lens and during which the user looks at a visual target located in the user's natural environment through the optical lens; and a suitability index assessing step, during which the user assesses a suitability index based on his use of the optical device in the plurality of different visual situations.

Devices/techniques coupleable to patient sensors, ambient environment, and external sensory input. Devices/techniques receive/maintain information; correlate received/maintained information with measures associated with detecting/monitoring, predict, prevent/treat, and train/reward patient self-care, for dry eyes. Devices/techniques detect/monitor, predict, and prevent/treat dry eyes in real time; and train/reward patients to conduct self-care for dry eyes. The devices/techniques provide adjusted sensory inputs to prevent/treat dry eyes, or to train/reward patients to conduct self-care for dry eyes. The devices/techniques cooperate with other devices, including devices worn by nearby patients, to receive/maintain information about the ambient environment, or communicate with medical personnel. The devices/techniques adjust parameters they use, in response to received information that differs from predictions, to provide superior behavior, and communicate with other devices and medical personnel. Devices/techniques are combined with devices/techniques that perform similar functions for other conditions, migraines/photophobia, neuro-opthalmic disorders, and other ocular conditions, and for combinations of dry eyes with other conditions.

A filter test kit for low vision is provided and may include a plurality of test frames. A test frame may include two sockets, a pair of optical lens tint components disposed in the sockets, a bridge connecting the sockets; and a tactile frame identifier. The pair of optical lens tint components for each frame is different from the pair of optical lens tint components of each other frame. Also, the tactile frame identifier for each frame is different from the tactile frame identifier for each other frame.

The present disclosure relates to trial scleral lenses, and the resulting scleral lenses, designed for the asymmetric shape of the sclera and/or its chiral properties. In some embodiments, the scleral lenses are also designed for the specific asymmetry associated with different scleral diameters. In addition, as discussed herein, the scleral shape can vary with different conditions of the eye. By designing a set of trial scleral lenses that takes into account these different asymmetric properties of the sclera, a clinician can be more efficient, fitting more eyes with fewer subsequent modifications. The resulting lenses will also achieve a better fit.
