Problems solved by technology

This kind of near-fog sight glasses is adjusted and relaxed during application, but it does not reduce the concentration force of the eyes, which can lead to incoordination between adjustment and concentration, making the concentration significantly larger than the adjustment, and it is easy to cause visual fatigue, eye pain, headache and so on to the wearer. Nausea and other symptoms, long-term application can easily cause common exotropia, and because it cannot relieve the oppression of the medial rectus muscle tension on the sclera wall during nearsightedness, it can only prevent pseudomyopia, but cannot fundamentally prevent true myopia. And the near-fog mirror cannot be used for the prevention and treatment of medium and high myopia above -3.00D

Embodiment 1

[0021] When a person wears myopia glasses and stares at a target 30 cm ahead, and the lens diopter is +1.00D, it is suitable for myopia patients from -0.50D to -2.00D, and the geometric center point of the lens is taken within the range of 1-10 cm outside the optical center point of the convex lens. .

[0022] When in use, place the thick sides of the two lenses on the nose side in the frame according to the normal installation method, place the frame on the bridge of the nose and fix it, and when the eyes look at the target 30 cm ahead through the lens, the target point The light enters the eye through the geometric center of the lens respectively. When the light passes through the geometric center of the lens, because the geometric center of the lens is not at the optical center of the convex lens sheet, the lens produces a prism effect, and the light bends at a certain angle toward the nose, and the eyeball In order to see the target clearly, it will turn to the side at a c...

Embodiment 2

[0024] When the diopter of the lens is +1.50D, it is suitable for myopia patients from -0.50D to -1.50D, and the geometric center of the lens is taken within the range of 1-6.6 cm outside the optical center of the convex lens.

[0025] The strapping method is the same as in Embodiment 1, and the effect is the same.

Embodiment 3

[0027] When the diopter of the lens is +2.00D, it is suitable for myopic patients with emmetropic eyes ~ -1.00D, and the geometric center of the lens is taken to be 0.5-5 cm outside the optical center of the convex lens.

[0028] The strapping method is the same as in Embodiment 1, and the effect is the same.

Abstract

The glasses include lenses and frame to hold lenses. The lens has geometric center deviating the optical center by 0.5-10 cm according to different diopter and is convex or concave lens suitable for high and middle-degree myopia over 3.00D. The glasses can relieve ciliary muscle from fatigue and remit the constriction of internal rectus muscle to eye ball wall so as to prevent and treat true myopia radically. Unlike available glasses, the present invention have less side effect.

Description

technical field [0001] The invention belongs to the class of medical instruments, in particular to an off-center myopia prevention mirror for treating myopia. Background technique [0002] Myopia therapy is currently recognized as one of the main effective methods for preventing and treating myopia below -3.00D. The device used is a convex lens with a certain diopter. The fog glasses sold on the market now use the optical center point of the lens The convex lens structure coincides with the geometric center of the lens, so that the optical center of the lens is exactly in line with the visual axis. When the eye is nearsighted, most or all of the adjustment of the eye is compensated, so that the ciliary muscle is in a certain relaxed state, thereby Reach the purpose of preventing and treating myopia. This kind of near-fog sight glasses is adjusted and relaxed during application, but it does not reduce the concentration force of the eyes, which can le...
