Description
Technical Field
The invention relates to a multifunctional lens with zones, in particular to a multifunctional lens with zones, and the multifunctional lens with zones can adjust the eye distance.
Background
In daily life, myopia is caused when the eyes are used for too long time, the eyes are too close to each other, and the illumination light is too strong or too weak. When the eyes are used for too long time or too close to each other, the burden of the eyes is increased, muscles inside and outside the eyes are in a tense state for a long time and cannot rest for a long time, and when the eyes look at a far place, the muscles of the eyes cannot relax and are in a spastic state, so that the eyes feel blurred when looking at the far place and finally form the myopia, or the myopia degree is increased under the condition of the myopia. When the eyes are fully relaxed, the sight line is focused at a distance; when looking at a near object, the eye has a ring of muscles (ciliary muscles) to begin to contract, the lens becomes convex, and then the focus of the line of sight is pulled to near, and the formula for calculating the refractive power required for the convex change is D1/distance (m). When an object approaches 0.33 m (one-arm distance, standard near vision distance), the ciliary muscle needs to use conventional strength (force value is 3D), the muscle is slightly sour for one hour continuously, but the muscle is not stiff and spastic, after rest, the muscle can be fully relaxed, and the crystalline lens can also recover the original shape. When the distance is reduced to 0.17m, the force required to be exerted by the ciliary muscle is linearly increased to the force application value of 6D, the load index of the ciliary muscle is increased, the endurance index is reduced, and the spasm is realized in a short time. Scientific studies have shown that a 17cm distance is 1 hour in eye use, which corresponds to a load of 4 hours in 33cm distance in eye use, so that near distance eye use has a great influence on the formation and progression of myopia.
The existing lenses on the market are mainly used for people with myopia, such as functional lenses for inhibiting myopia and hypermetropia of human eyes, but the lenses cannot prevent myopia, and the myopia can not be prevented from being deepened when a user uses the eyes for a long time at a short distance, the lenses cannot correct the distance between the user and the eyes, particularly the distance between the user and a book or a homework when the student learns, and the efficacy of the functional lenses is greatly reduced when the user uses the eyes for a long time at a short distance with incorrect sitting posture.
Prior patent "spectacle lens", application number: 201310628174.8 which teaches an ophthalmic lens that inhibits the progression of myopic eyes by imaging a second refractive power at a location in front of the retina, but the lens of the invention of this patent (application No.: 201310628174.8) does not prevent myopia and does not prevent the progression of myopia when the user is using the eye at near distances for extended periods of time, where the efficacy of such lenses is greatly diminished.
