An ophthalmic device for binocular vision testing. The patient views a two image pairs stacked (Top = right dim image/left bright image; Bottom = right bright image//left dim image) through polarizing glasses of a polarizing system and informs the examining doctor when the combination perceived changes. This visual impression provides the information whereby a diagnosis of unconscious suppression of one eye can be determined.

A hand-held device that illuminates the eye while viewing a visual acuity chart for measuring the presence and degree of glare.

A digital vision testing system intended as an aid in assessment of visual function in patients. The software delivers algorithms that utilize a visual display which may be a tablet, smart phone, a computer screen, etc.

Frames for holding lenses and occluder used for vision testing.

An individual ophthalmic lens from a trial lens set. (lens holder)

An ophthalmic device (a bar reader) consisting of a magnifying lens intended to magnify the print of reading material and to be used by a patient/person with impaired vision. The device is placed directly onto reading material which is read from above. It can be made of solid glass or plastic material.

A flexible device intended to be used in a clinical setting to establish an accurate measurement of length greater than a standard ruler (e.g., the girth of a patient's waist or thigh, or the length of a leg). It is typically made of oilcloth or pliable steel and marked in units of length (i.e., inches and/or millimeters). It is usually available as a roll which may be encased in a holder. This is a reusable device.

MacDx Dark Adaptometer is a device to measure dark adaptation of the retina.

An ophthalmic device that consists of various coloured materials, e.g., coloured yarns or colour vision plates (multicoloured plates which patients with colour vision deficiency would perceive as being of one colour), used for evaluating colour vision.

A hand-operated, non-powered ophthalmic device intended to temporarily prevent and/or attenuate the passage of light (vision) to the eye(s) during an eyesight examination (e.g., diagnosis/measurement of heterophoria/heterotropia, myopia). The part of the device used to cover the eye(s) is typically spoon- or oval-shaped, and may be fully opaque or incorporate small holes and/or a Maddox lens(es) [i.e., coloured lens(es)]; the device also incorporates a handle and/or binocular frame. This is a reusable device.

Glasses that change the plane of polarization when linearly polarized light traverses an optically active solid or liquid. This device may also be used in ophthalmology.

An individual ophthalmic lens from a trial lens set having multiple pinholes separate by clear plastic.

A lens clip having an optical lens and a pinhole disc with multiple apertures, each surrounded by an opaque halo.

A lens chip having an optical lens and a pinhole disc with multiple apertures.

An ophthalmic retro-illuminated chart printed with various symbols (letters, numbers, pictures, dots) intended to be used for testing visual acuity (e.g., Snellen chart) for routine visual function examination (e.g., preoperative visual acuity prediction and postoperative visual acuity recovery assessment for cataract, glaucoma, retinopathy, amblyopia, etc.). The chart is exchangeable.
