I'm 16 years old. My left eye is 38 degrees and my right eye is 3 degrees. Can I wear McGregor? I heard what my classmates said about McGregor, but I don't know if it really works.

Your question is "Is it really effective to wear a McGrady?". I checked the website of Madige, and there are two kinds of products: 1. Orthokeratology mirror; 2. Corneal contact lens. I only talk about the principle and advantages and disadvantages.

Orthokeratology lens, abbreviated as OK lens, is a kind of permeable and breathable rigid contact lens, which can be divided into daily wear type and night wear type, while Madiger's is night wear type. Wearing OK glasses on the cornea can flatten the central area of the cornea and reduce the refractive power of the cornea to improve vision. This is the same as laser surgery, which is to reduce the refractive power of the cornea to see clearly, but the method of reducing the diopter of the cornea is different. OK glasses adopt the compression method, and laser surgery adopts the method of cutting off a layer of cornea with laser. The advantage of OK mirror is that it can improve vision quickly and effectively. The disadvantage is that the cornea is elastic. After being flattened, it will return to its original state after stopping wearing, and the vision will be reduced. You can ask McGregor how to prevent it from bouncing back to its original state, but no matter how he explains it, he can't get around the problem of corneal elasticity. In addition, it may also cause complications, such as corneal injury, decreased corneal perception, corneal ulcer and so on.

The contact lens is also worn on the cornea, and it can be seen clearly through the power of the lens. The principle is the same as that of frame glasses, which is to shorten the focal length with a concave lens, so that the focus falls on the retina. Corneal contact lenses also have the above complications.
