Medical tests and examinations are performed with consumer computing devices. The medical tests and examinations are selected and customized in accordance with conditions present in the testing environment, as well as physical characteristics of a user taking the test. The tests can include visual acuity tests, colorblindness tests and other medical tests, such as hearing tests.

Methods, devices, and systems are disclosed for determining refractive corrections of human eyes to reduce and eliminate image distortion associated with eyeglasses. In some embodiments, an objective refraction module is configured to measure refractive errors of an eye objectively, without subjective feedback from a tested subject. A computation module is configured to generate a plurality of objective prescriptions. A phoropter module is configured to perform a subjective refraction for determining a plurality of subjective spherical powers based on the plurality of objective prescriptions. An output module is configured to generate a plurality of prescriptions for eyeglasses, the plurality of prescriptions comprising (a) a first prescription having a first subjective spherical power f.sub.s1, a first objective cylinder power F.sub.c1, and a first objective cylinder angle F.sub.a1, and (b) a second prescription having a second subjective spherical power f.sub.s2, a second objective cylinder power F.sub.c2, and a second objective cylinder angle F.sub.a2.

The invention provides a system for a patient to obtain quality eye tests results without other people's assistance. The system includes a wearable, head-mounted, ophthalmic device. With a head mounted structure, the patient's head position remains still relative to the ophthalmic device. One or more “iris” cameras and a display screen are used to help align the patient's eye on ocular lenses for optimal eye test results. The system includes a patient interface module that allows the patient to operate the device. Accessory features such as a microphone and earphones are used to communicate with a close by stander during and after the eye exam. Another key feature is a cloud service connection used to store test results for remote access by the patient or other authorized persons.

An ophthalmic apparatus is capable of communicating with a PDA device provided with a display unit and includes a main body that includes an image-capturing unit, the image-capturing unit obtaining a moving image of an eye to be examined (target eye) based on light returned from the target eye which is illuminated, the moving image of the target eye used by the ophthalmic apparatus for obtaining, based on an examination of the target eye, information regarding the target eye, a driving unit that drives the main body, a transmission unit that transmits, before the information regarding the target eye is obtained, a moving image signal of the obtained moving image to the PDA device, a reception unit that receives a control signal from the PDA device during transmission of the moving image signal, and a control unit that controls the driving unit based on the received control signal.

Method, system and computer program for measuring light diffusion in the eyeball or in the ocular region.

The method comprises: projecting a punctiform light beam onto the retina; correcting low-order ocular aberrations of the eye; capturing and recording an image of the retinal plane formed after reflection of the punctiform light beam on the retina and a double passage through the ocular media of the eye; and at the same time as capturing the image of the retinal plane, performing a high- and low-order ocular aberration measurement in the plane of the pupil and performing a light diffusion measurement, combining ocular aberration measurement information with information on the image of the retinal plane.

The system and the computer program are adapted for implementing the method.

The ophthalmological device of an embodiment includes an optical system for inspection, a display, a subject's eye position acquiring unit, and a control unit. The optical system for inspection includes a photographic optical system for photographing an eyeground of the subject's eye. The subject's eye position acquiring unit acquires a three-dimensional position of the subject's eye. The control unit acquires information on positional displacement of the optical system for inspection with respect to the subject's eye on the basis of the three-dimensional position to cause a screen of the display to display two alignment index images to be varied in position with respect to a reference position of alignment preset in the display in a pseudo manner, in accordance with the information on positional displacement.
