Abstract

The utility model relates to a pair of pupil distance adjustable health glasses emulating pupils, which is composed of metachromatic lenses (3) and a glasses frame (1), wherein, a left and a right internal grooves of the glasses frame (1) are respectively provided with two screw rod (5) of which the outer ends are fixed on glasses legs (2), a glasses case (7) is embedded in a groove (8), and the upper edge of the glasses case is fixed with a screw cap (6) which is matched with the screw rod (5). The utility model has a dynamic pupil emulating effect and a simple function of adjusting pupil distance, aims at overcoming the non-adjustability of traditional coloured glasses or stenopeic glasses, and is suitable for the fields of daily life, medical care, labour protection, etc.

Description

Pupil distance adjustable health glasses

The utility model relates to the glasses of the adjustable interpupillary distance of a kind of imitative pupil.

Common light-sensitive sunglasses (the flat mirror, convex lens, the concavees lens that comprise variable color) variable color under high light is dark, can not become transparent in the indoor or low light level following time, and a kind of diaphragm feeling is arranged, and is especially more not convenient for ametropic people is arranged originally.

Temporary or permanent diffusing big through regular meeting in clinical ophthalmology because of all multifactor pupils that causes such as inspection, treatment, wound; the patient can occur keeping in dark place and the phenomenon of blurring of vision; at this moment, the doctor often puts on pinhole spectacles (stenopeic spectacle) or coloured mirror of protectiveness to the patient.These glasses forms are indecency, the visual field is limited, ungoverned leeway under strong, decreased light.

The interpupillary distance of common spectacles is changeless, and both vigorous, interpupillary distance of incompatibility bone growth and socket of the eye be apart from the teenager who increases in direct ratioly, also the incompatibility adult look far away with look interpupillary distance when near (optical center of lens apart from) and change.

The purpose of this utility model provides the glasses of the adjustable interpupillary distance of a kind of imitative pupil, and it has the interception of common tinted glasses under high light, and it is clear to look thing in the low light level following time, has eliminated diaphragm feeling; Simultaneously, the interpupillary distance of this glasses can be regulated quickly and easily.

This is suitable for novel purpose and is achieved in that eyeglass (3) can be various color-changing lens.Requiring this eyeglass is the center with its photocentre, gradually equably to around increase progressively variable color intensity.When meeting high light, the center of lens look that shoals, the nearly peripheral variable color of healing is darker, prevent that too many light from entering intraocular; And the center of lens district becomes more transparent under the low light level, exactly likes that pupil dwindles under high light, the big physiological property of loosing under the low light level.This is the essence of imitative pupil.

Mirror holder (1) left and right sides inside groove is respectively put a screw mandrel (5) (but the plastics weight reduction of drawing materials), and screw mandrel (5) outer end is fixed on the mirror leg (2).Picture frame (7) is embedded in the groove (8), and the picture frame upper limb is fixed a silk cap (6), with screw mandrel (5) supporting (the fine and closely woven more adjusting of silking is accurate more).When with eyeglass (3) vertical direction clockwise or counterclockwise rocking-turn mirror leg (2), picture frame (7) can be along screw mandrel (5) move left and right, thereby adjust interpupillary distance (photocentre distance), in order to strengthen the steadiness of mirror holder, can adorn one above the outboard end in mirror holder (1) can be along the sheet metal (4) of fulcrum rotation, and this sheet metal (4) lid is depressed into the outer rim of mirror leg joint.Open the promptly rotatable mirror leg (2) of sheet metal (4), return sheet metal then mirror leg is able to firmly.

The advantage of the utility model glasses: 1.. various in the past stenopeic spectacles (comprising the non-penetrative aperture mirror) only are equivalent to one " static pupil ", and the center of the utility model eyeglass is equivalent to one " dynamically pupil ", meets physiological property.

2.. rotate the adjusting that the mirror leg can be finished the socket of the eye distance, need not add other regulating device.Thereby outward appearance is the same substantially with common spectacles, generous, light and handy, wears comfortable.
