Myopia preventing and treating glasses

Technical field

The utility model relates to ophthalmic articles, especially a kind of myopia preventing and treating glasses that can be used for preventing and treating myopia.

Background technology

Pleasing to the eye only divergent rays during people's reading and writing, see that pleasing to the eye light is parallel rays when far away, need not regulate after parallel rays is pleasing to the eye on the retina that images in normal eye just, and divergent rays must just can be imaged onto on the retina through regulating after going into normal eye, and long-term adjusting can cause that eyes muscular fatigue just can excite myopia.Convex lens energy optically focused, it is pleasing to the eye to make diverging light become directional light, therefore wears convex lens reading eyes and just need not regulate.

Eyes not only will be regulated during reading, and two eyes must be aimed at nearby on the word, and are so two sight line must be gathered during reading, promptly so-called converge like the spokes of a wheel at the hub.Prism can change the direction of pleasing to the eye light.So normally watching when near not only needs to regulate but also need set, regulate and set is carried out synchronously.So only also not all right by convex lens, must change the direction of pleasing to the eye light by substrate prism to the inside.

On the basis of above-mentioned principle, produced existing myopia preventing and treating glasses, eyeglass is to be constituted by prism and convex lens that the bottom is positioned at the glasses inboard, sees and uses when near, looks every day closely twice, each 30 minutes, does not influence reading study when near seeing.The effect of prism is to see see closely to be converted into far, uses glasses to regulate converge like the spokes of a wheel at the hubly seeing can not produce when near, has solved and has regulated and the contradiction of regulating between converge like the spokes of a wheel at the hub geometry, has promptly solved watching the problem of book.The effect of convex lens is: people see the adjusting power that needs ten 3.00D when near, just tell me and to add the convex lens that ten 3.00D degree are above when near, see that eye is exactly the acyclic homologically trioial joint when near, if give ten 3.00D above convex lens, will oppositely regulate, thereby reach the purpose of controlling with pre-myopia prevention.Existing myopia preventing and treating glasses has produced positive effect to the prevention and the treatment of myopia, and its deficiency is that prism and convex lens are to fix, and to A nearsighted person's use is very not convenient in various degree, in addition, eyeglass is an optical glass, and weight is big.Also having a kind of myopia preventing and treating glasses is little prism on fitting on the basis of optical glass concave lens, and shortcoming is unbecoming, and weight is big, inconvenience.
