Description
Technical Field
The invention belongs to the technical field of medical equipment, and relates to optometry equipment.
Background
The optometry lens must be accurate as known, otherwise discomfort is brought or the degree change is aggravated, optometry is also a necessary link for refractive surgery (laser vision correction, vision correction by implanting various artificial lenses, etc.), and because of the irrecoverability of the surgery to a certain extent, the optometry value is as accurate and reliable as possible before the surgery.
The parameters obtained after refraction form a prescription or are used as reference values for correcting ametropia by surgery, and can be mainly divided into three major parts: sphere power (diopter of spherical power, DS), cylinder power (diopter of cylindrical power, DC), cylinder axis (in degrees, sign).
In the conventional subjective refraction procedure, the patient needs to give the lens holder for the insertion piece to be subjected to refraction, or a comprehensive refraction instrument, but these devices have disadvantages: if the inserting lens frame is just a male design, the structure of the frame leg and the nose support cannot adapt to the face shape of each person, the design limit exists (the positions of two eyes of each person are different, the nose shape and the ears are different), the test lens can incline and skew in front of the eyes, the center of the lens is difficult to be matched with the visual axis of the eyeball or the center on the optical axis, and the best customized test light effect is difficult to achieve. If the comprehensive optometry instrument has similar problems, the forehead of a person is attached to the comprehensive optometry instrument, at the moment, the head position is not in a natural daily life state, horizontal/vertical inclination of the head position can occur, even rotary inclination (the face of a person can not be perceived to be inclined to one side) can occur, even the position of the lung (the comprehensive optometry instrument) can be adjusted, the sitting posture is also high, the person still needs to control the neck and the body of the person to complete the action of fixing the forehead to attach to a machine, the link is not quantized, and at the moment, the psychological state and the eye position movement state are likely to be different from those of daily life, and the measuring degree process is affected. In practice, various links of the conventional optometry technology inevitably have the inclination of eyeballs, which is different from the prior optometry technology in that the inclination is larger or smaller. In the optometry process, the deflection of the eyeball due to the head position is even 1-3 degrees, so that the optical optometry can be greatly influenced.
