  • Patent number: 10716707
    Abstract: Active dichoptic perceptual-learning tasks or dichoptic game play have been shown to significantly improve visual acuity of amblyopic children and adults. However, these dichoptic perceptual learning tasks are intensive and repetitive such that non-compliance is high. In contrast, the invention provides dichoptic perceptual learning in a manner that the user maintains its use and compliance is increased. Further, compliance becomes automatic if the user performs tasks in a normal manner and “forgets” that they are actually undergoing treatment as it is integrated with minimal disruption to their life and activities. Accordingly, a methodology exploiting complementary dichoptic stimulation is presented.

  • Patent number: 10379356
    Abstract: An auto-focus head-mounted display (HMD) dynamically generates aberration-adjusted images based on measured accommodation of user's eye(s). An aberration-adjusted image is an image distorted to correct aberrations that would otherwise occur at a retina of the user due to image light passing through optics of the HMD. The aberration-adjusted image corrects the aberrations of the HMD and “accounts” for the aberrations of the eye so that the resulting retinal image is free of optical aberrations due to the HMD but preserves correct eye optical aberrations that are correlated with a current accommodative state of the eye.

  • Patent number: 8950865
    Abstract: A viewing target for a visual acuity and refraction measurement includes at least one line comprising a width dimension that is below a resolution limit width (hereinafter “RLW”) of a test subject visual acuity, and an adjustable length dimension that is initially set at greater than the RLW of the test subject visual acuity. A base, at least approximately intersecting the line, has a thickness along the direction of the length of the line that is greater than the RLW of the test subject visual acuity. The length dimension of the line is adjustable in increments small enough to effectively approximate the visual acuity of the test subject by determining a shortest resolvable line and a next smaller line that is not resolvable by the test subject.

  • Patent number: 8915592
    Abstract: Apparatuses and methods employing ocular surface interferometry (OSI) employing polarization and subtraction for imaging, processing, and/or displaying an ocular tear film are disclosed. The apparatuses and methods can be employed for measuring tear film layer thickness (TFLT) of the ocular tear film, which includes lipid layer thickness (LLT) and/or aqueous layer thickness (ALT). An imaging device is focused on the lipid layer of the tear film to capture optical wave interference interactions of specularly reflected light from the tear film combined with a background signal(s) in a first image. The imaging device is focused on the lipid layer of the tear film to capture a second image containing background signal(s) in the first image. The second image can be subtracted from the first image to reduce and/or eliminate background signal(s) in the first image to produce a resulting image that can be analyzed to measure tear film layer thickness (TFLT).

  • Patent number: 8814360
    Abstract: Disclosed are a method and kit for testing visual acuity in a subject. The examiner displays a test thread at a set distance in front of the subject's face, and then determines whether the subject grabs or looks at the test thread. These steps are repeated using subsequent threads of varying thickness. The smallest thread to which the subject responds is charted as their best VA in standard notation. The visual acuity of a young child can be quantified using standard adult Snellen acuity levels. The device can be used worldwide, as it transcends language barriers, and in a variety of practice settings, including pediatric ophthalmologist offices, general ophthalmologist offices, optometric offices, pediatricians and family doctors who see young children or persons unable to read a conventional Snellen chart and/or verbalize their responses.
