Tinted non-prescription spectacles

49,612 GUDID devices

An optical device, commonly known as sunglasses, that consists of a spectacle frame or clips with a pair of tinted spectacle lenses (typically made of plastic or glass) designed to be worn in front of the eyes to attenuate light radiation by absorption, ref...

Tinted non-prescription spectacle lens

2,329 GUDID devices

An ophthalmic lens made of a treated glass or plastic intended to be worn in front of the eyes to attenuate rays of light by absorption, reflection, or polarization to protect the eyes from bright light; it is neither intended to provide refractive correcti...

Tinted spectacle lens, non-prescription

380 GUDID devices

An ophthalmic device made of a treated glass or plastic that is used to attenuate rays of light by absorption, reflection, or polarization to protect the eyes from bright light, but not to provide refractive corrections. This device may require cutting to e...

Ophthalmic slit lamp, examination

330 GUDID devices

A mains electricity (AC-powered), ophthalmic, binocular microscope designed to examine the interior anatomy of the eye (anterior and posterior surfaces) by viewing through the iris. It produces a narrow slit of powerful light which is projected into the eye...

Automated ophthalmic refractometer

89 GUDID devices

An electrically-powered, ophthalmic device designed to be used by a healthcare professional to objectively measure the refractive error of the eye (the inaccuracies of focusing light upon the retina) by measuring how light is changed when it enters the pati...

Ophthalmic slit lamp, examination

75 GUDID devices

An electrically-powered, ophthalmic, binocular microscope designed to examine the interior anatomy of the eye (anterior and posterior surfaces) by viewing through the iris. It produces a narrow slit of powerful light which is projected into the eye, and res...

Ophthalmic examination slit lamp

56 GUDID devices

An electrically-powered, ophthalmic, binocular microscope designed to examine the interior anatomy of the eye by viewing through the pupil; it is not dedicated to surgical procedures. It projects a narrow slit of light into the eye and resulting light refle...

Indirect binocular laser ophthalmoscope

23 GUDID devices

An electrically-powered, head-worn, ophthalmic device used for the stereoscopic examination and laser treatment of the eye, particularly the retina. It typically consists of a headband, a built-in light with aperture control for adjustment of the illuminati...

Indirect binocular laser ophthalmoscope

15 GUDID devices

A mains electricity (AC-powered), head-worn, ophthalmic device used for the stereoscopic examination and laser treatment of the eye, particularly the retina. It typically consists of a headband, a built-in light with aperture control for adjustment of the i...

Keratoscope, non-powered, reusable

7 GUDID devices

A non-powered, hand-held, ophthalmic instrument intended for qualitative assessment of the curvature of the anterior surface of the cornea, typically to detect astigmatism during ophthalmic surgery (e.g., changes induced by sutures during corneal transplant...

Acoustic rhinometer

5 GUDID devices

A line-powered (AC-powered), or powered via a connected computer, electronic device designed to allow the internal profile of the nose to be recorded in order to quantify the degree of obstruction/congestion in the nasal cavities and provide monitoring of t...

Tinted spectacles, non-prescription

3 GUDID devices

An optical device that consists of a spectacle frame or clips made of metal and/or plastic materials that contains a pair of tinted spectacle lenses (typically made of plastic or glass) that are worn in front of the user's eyes to attenuate light radiation ...

Keratoscope, powered

2 GUDID devices

An electrically-powered ophthalmic device intended for qualitative assessment of the curvature of the anterior surface of the cornea, typically to detect astigmatism during ophthalmic surgery; it is not a keratometer. It may be designed as a hand-held instr...

Non-corrective tinted spectacles

2 GUDID devices

An optical device, commonly known as sunglasses, that consists of a spectacle frame or clips with a pair of tinted spectacle lenses (typically made of plastic or glass) designed to be worn in front of the eyes to attenuate light radiation by absorption, ref...

Intracranial haematoma detector

1 GUDID devices

A noninvasive, hand-held, rechargeable battery-powered device intended to be used to scan a patient¿s head for the detection of an intracranial (e.g., epidural, subdural and intracerebral) haematoma, using near infrared (NIR) technology. It consists of a co...

Keratoscope, non-powered, single-use

1 GUDID devices

A non-powered, hand-held ophthalmic instrument intended for qualitative assessment of the curvature of the anterior surface of the cornea, typically to detect astigmatism during ophthalmic surgery (e.g., changes induced by sutures during corneal transplanta...

Near-infrared intracranial haematoma detector

1 GUDID devices

A noninvasive, hand-held, electrically-powered device intended to be used to scan a patient’s head for the detection of an intracranial (e.g., epidural, subdural and intracerebral) haematoma, using near-infrared (NIR) technology. It consists of a control un...

Paediatric strabismus screening scanner

1 GUDID devices

An electrically-powered optic device designed for screening for strabismus and amblyopia risk in children (aged 2 to 8 years) by using retinal reflections of polarized laser light to/from both eyes simultaneously. It consists of a self-contained unit which ...
