Combined myopia preventing and treating glasses

Abstract

The invention discloses a pair of combined myopia preventing and treating glasses, which comprises a pair of primary glasses and three groups of independent secondary glasses. The pair of primary glasses is a pair of shortsighted glasses and comprises a spectacle frame (1) and a pair of primary shortsighted eyeglasses (2). The first group of secondary glasses can be attached below the front faces or back faces of the main shortsighted eyeglasses (2) through connecting clamps (3); secondary eyeglasses thereof are formed by compounding 2 to 3.5 D convex spheres and 4 to 7 triangular prisms of which the base is inwards; and the first group of secondary glasses are especially suitable to be used by a student in class, wherein the student uses the upper half to look at a blackboard, and the lower half changes a near sight into a far sight when the student reads or writes so as to prevent the development of myopia. The second group of secondary glasses can be attached above the front faces or back faces of the main shortsighted eyeglasses (2); and secondary eyeglasses thereof are 3 to 5 D convex spheres and treat myopia in a far fogging mode. The third group of secondary glasses can be attached above the front faces or back faces of the main shortsighted eyeglasses (2); secondary eyeglasses thereof are formed by compounding 1 to 2 D convex spheres and 2 to 4 delta triangular prisms of which the base is inwards; and the third group of secondary glasses is especially suitable to be used by the user for watching a computer, and can eliminate eye fatigue, prevent and treat myopia.

Description

technical field [0001] The invention relates to a myopia prevention and treatment glasses, in particular to a myopia prevention and treatment glasses which can treat pseudomyopia and prevent the occurrence and development of true myopia. Background technique [0002] For young students with heavy learning tasks, long-term near-sightedness is the main cause of myopia. A considerable part of young students in this age group is pseudo-myopia. Treatment can restore vision and prevent the transformation from pseudo-myopia to short-sightedness. True myopia. [0003] In the prior art, there are examples of prevention and treatment glasses that have a certain effect in preventing and treating myopia, but all have their own obvious deficiencies without exception. Two representative prevention and treatment glasses, one such as Chinese Patent No. 99234597, is called myopia regression Glasses are used to reduce the adjustment and concentration of human eyes when nearsightedness, and h...

Problems solved by technology

[0003] In the prior art, there are examples of prevention and treatment glasses that have a certain effect in preventing and treating myopia, but all have their own obvious deficiencies without exception. Two representative prevention and treatment glasses, one such as Chinese Patent No. 99234597, is called myopia regression Glasses are used to reduce the adjustment and concentration of human eyes when nearsightedness, and have a certain effect on protecting the eyesight of young people and preventing myopia. However, this kind of glasses can only be used at a distance of about 33 centimeters, and there are many inconveniences for students when using them. It is very inconvenient to use, and it is difficult for children to persist, and the prevention and treatment effect is greatly reduced; another kind, such as Chinese Patent No. 200520085029.0, is called myopia prevention glasses. The lens of the above patented glasses is reduced to sub-pieces, glued to the lower part of the lens of the myopia lens, and the glasses and the myopia lens that have the function of preventing and treating myopia are combined into one, which solves the trouble of exchanging two pairs of glasses. However, this This kind of glasses is very unattractive, and children are not willing to wear them. Moreover, the cost of this kind of glasses is relatively high, which is not conducive to popularization

[0004] The above two kinds of prevention and treatment glasses are all from the consideration of reducing the adjustment and concentration of students when reading and writing, and simulate the near-sighted state of the eyes as a telescopic state. It takes a long time and the effect is not significant enough, parents and children are easy to give up

Moreover, for children who often face the computer, due to the change of the visual distance, the parameters of the above two prevention glasses need to be re-determined, and the corresponding second pair of prevention glasses must be prepared, which is both troublesome and uneconomical.
