Description

Lens Combination Method for Adjusting Optical Focus Position in Eye

Technical field:

The invention relates to vision correction and physical therapy, in particular to a lens combination method for adjusting the optical focus position in the eye.

Background technique:

As everyone knows, the existing methods of vision correction and physiotherapy adopt or use for reference the mechanism of fog vision method mostly.

The so-called fog vision method is to make the tested eye in the "artificial myopia state", even if the object image is gathered in front of the retina. The fog vision method can reduce the burden of seeing near through the convex lens, thereby preventing myopia.

At present, this method is mainly aimed at myopia patients under the age of 18. Wearing +100DS, +200DS, +300DS convex lenses to work and study for a certain period of time will have a certain effect on a small number of people in the audience and improve naked eye vision.

It can be seen that the fog vision method has the following defects in the actual application process:

1. The degree of convex lens is limited, the audience is not universal, the effect is not good, and it is impossible to make personalized adjustment plans that vary from person to person.

2. It is only limited to the use of convex lenses, and the intraocular optical focus can only be adjusted in a limited degree in one direction, and the combination of convex lenses and concave lenses is not used.

3. The constant use of convex lenses results in a limited range of visual acuity improvement, and the audience is very prone to tolerance, and it is impossible to achieve long-term systematic training to help visual acuity recovery.

Invention content:

In view of the above technical problems, the present invention provides a lens combination method for adjusting the position of the optical focus in the eye. This method is aimed at myopia patients, using convex lenses and concave lenses, and carrying out personalized training programs according to the combination of convex lenses or convex-concave lenses of different degrees according to different visual acuity patients, improving the function of the ciliary muscle to adjust the lens, thereby improving uncorrected visual acuity, with an effective rate of 95%. %above.

Concrete technical scheme of the present invention is as follows:

A lens combination method for adjusting the position of the optical focus in the eye, the method comprising:

Step 1: Use a single set of convex lenses of different degrees to be applied in front of the eyeball of the myopia patient, so that the optical focus position passing through the eyeball moves from the original position to the direction of the intraocular lens. The vision training lasts for 30 minutes;

Step 2: Apply two sets of convex lenses with different degrees in front of the eyeball of the myopia patient, so that the optical focus position in the eyeball moves from the original position to the direction of the intraocular lens. The vision training lasts for 30 minutes;

Step 3: Use two concave lenses with a multiple relationship and two convex lenses with a multiple relationship to be respectively applied in front of the eyeball of the myopia patient, so that the optical focus position in the eyeball moves back and forth to the direction of the retina and the direction of the lens respectively. The time lasts 30 minutes.

In the above solution, the range of the convex lens used is +12.5DS to +2000DS.

In the above solution, the range of the concave lens used is -12.5DS to -2000DS.

In the above scheme, in the step 3, a low-degree concave lens is first applied in front of the eyeball of the myopia patient, and the vision training time lasts for 5 minutes, and then a multiple concave lens is applied in front of the eyeball of the myopia patient, and the vision training time lasts for 5 minutes. 5 minutes, and then apply it to the eyeball of the myopia patient with a low-degree convex lens, and the vision training time lasts 10 minutes, and finally apply it to the eyeball of the myopia patient with a multiple convex lens, and the vision training time lasts 10 minutes.

The beneficial effects of the inventive method are:

1. This method can wear convex lenses of different degrees according to different eyesight, so that the audience is more general, more personalized and targeted, and the effect of improving naked eye vision is more general and better.

2. The method uses a combination of convex lenses of different degrees and concave lenses of different degrees, so that the optical focus position in the audience's eyes can move to the direction of the retina and lens respectively, so as to achieve two-way adjustment and improve the effect of naked eye vision.

3. Due to the finer degrees of the convex lens and the combination with the concave lens, the tolerance of the audience is greatly reduced, and long-term systematic training can be achieved, which improves the effect of improving naked eye vision.

Detailed ways:

In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

The lens combination method for adjusting the optical focus position in the eye for vision correction and restoration according to the present invention involves the use of a convex lens with a power range from +12.5DS to +2000DS, and a concave lens with a power range from -12.5DS to -2000DS, for patients with different vision, wear a convex lens or convex-concave lens combination of different degrees to carry out personalized training programs, so as to improve the function of the ciliary muscle to adjust the lens, so as to improve the naked eye vision.

The general principle is divided into the following steps:

Step 1: For the eyeball of a patient with myopia (see Figure 1), a single set of convex lenses 40 of different powers is applied in front of the eyeball of the myopia patient, so that the position of the optical focus 3 passing through the eyeball moves from the original position to the inside of the eye The lens moves in 2 directions, and the vision training lasts for 30 minutes, as shown in FIG. 2 .

The second step: on the basis of the first step, two sets of convex lenses (41; 42) of different degrees are applied in front of the eyeball of the myopic patient, so that the position of the optical focus 3 passing through the eyeball is further toward the intraocular lens from the original position Moving in 2 directions, the vision training lasts for 30 minutes, see Figure 3.

Step 3: On the basis of the second part, use two concave lenses with a multiple relationship and two convex lenses with a multiple relationship to be applied in front of the eyeballs of myopia patients, so that the optical focus positions in the eyeballs are directed toward the retina and The direction of the lens moves back and forth, and the vision training lasts for 30 minutes.

For the third step above, the details are as follows:

(1) Apply a low-power concave lens 50 in front of the eyeball of a myopic patient, so that the position of the optical focus 3 moves toward the retina 1. The vision training lasts for 5 minutes, see Figure 4a.

(2) Afterwards, a multiple concave lens (51; 52) is applied in front of the eyeball of the myopic patient, so that the position of the optical focus 3 is further moved to the direction of the retina 1. The vision training lasts for 5 minutes, see Figure 4b.

(3) Then apply a low-power convex lens 60 in front of the eyeball of the myopic patient, so that the position of the optical focus 3 moves toward the lens 2. The vision training lasts for 10 minutes, see Figure 4c.

(4) Finally, a multiple convex lens (61; 62) is applied in front of the eyeball of the myopic patient, so that the position of the optical focus 3 is further moved to the direction of the lens 2, and the vision training lasts for 10 minutes. See Figure 4d.

The following is illustrated by a specific example:

For example: For patients with 0.4 visual acuity in both eyes, the first step is to train with +1.5DS lenses for 30 minutes, and then visual training for 10 minutes. When the patient's vision has improved, he will use +2.0DS to carry out the same game training process, which is the second step. When the patient's vision improves to a certain level and no longer improves (after the tenth time), the third step will be adopted, which is the joint application method of convex and concave lenses: first train with -1.00DS lens for 5 minutes, and then train with -2.00DS for 5 minutes Minutes, then use +1.75DS for 10 minutes of training, 10 minutes of visual training, and then use +3.50DS for 10 minutes of training, the optical focus will move forward and backward, which will increase the range of focus movement and improve vision.
