One eye of a cat is blue, the other is brown. What’s the matter with cat’s eyes, one is yellow and the other is blue?

       Shandong lion cat Linqing, also known as Shandong lion cat, is a variation bred by crossing the Persian cat with blue eyes and the local domestic cat with yellow eyes. Among the many varieties, the snow lion with a blue eye, a yellow eye and white fur mopping the ground is the most precious. People call it “mandarin duck eye lion cat”. Its blue eye is like a clear lake, a gem, crystal clear. The yellow eye is like the setting sun of molten gold, which is glittering and transparent.

       Linqing lion cat, also known as Shandong lion cat, is a variation bred by crossing the blue eyed Persian cat with yellow eye and the local domestic cat with yellow eye. Among the many varieties, the snow lion with a blue eye, a yellow eye and white fur mopping the ground is the most precious. People call it “mandarin duck eye lion cat”. Its blue eye is like a clear lake, a gem, crystal clear. The yellow eye is like the setting sun, shining golden, clear and transparent.

       Genetic problems, most of these cats are congenital deaf. Try to see if your kitten can hear sound. If you can, I have two pure white cats with mandarin duck eyes. One is not deaf, the other is completely deaf. If your cat can hear you, you are very lucky. Mandarin duck eyes are so beautiful.

       The following is from Baidu Encyclopedia: some cats (such as China Linqing lion cat and Angora cat) have genetic defects, with beautiful blue eyes but deaf ears. So people crossbreed yellow eyed white cats with this kind of cat to breed mandarin duck eyed cats, a white long haired cat with yellow and blue eyes, but deafness defects may also appear on one side of the blue eye.

       This is mandarin duck’s eye. It refers to the condition that two eyes of the same animal are different colors. It usually appears in white cats. It is generally believed that the two eyes of purebred cats are the same color, and the eyes of mandarin ducks are caused by hybridization.

       The eye color of Persian cat depends on the color of its fur. It is generally believed that the eye color of Persian cat includes blue, green, copper, gold, amber, strange color, and two eyes have different colors (namely mandarin duck eyes). The coat color of mandarin duck eyed Persian cat is usually white. A cat with green, amber and golden eyes, usually of the silvery gray coat. The purer and darker the color of all kinds of eyes is better, and the color uniformity of two eyes is better.

       The lion cat is a typical mandarin duck eye, with blue and yellow eyes. Usually, its fur is white. It has a mild personality. It looks like a Persian cat and is similar to a lion. Therefore, it is named lion cat. Due to its low reproductive capacity and few pure breeds, it belongs to one of the famous cats in China.

       Extended data

       At the same time, for human beings, there are “mandarin duck eyes”. The vision of two eyes is different, which is called anisometropia in medicine. This is a common phenomenon in the crowd, but if the degree of two eyes is too far, it will become “mandarin duck eyes”, which will cause the size of the object to be seen by the left and right eyes, making the brain at a loss and losing the stereoscopic sense of vision. It is called “heterochromatic pupil” in ACG circle.

       1. Correction method

       (1) The simplest way to treat anisometropia with frame glasses is to wear spectacles. Children have greater adaptability and plasticity. They can accept frame glasses well. They can be prescribed according to the need during the lens test. For anisometropia below 6.00D, full correction or near full correction should be carried out actively, instead of being bound by the principle of no more than 2.50d.

       The vision of 3-7 years old children with anisometropia can be improved by 4 lines and almost half of them can be cured completely. If the vision does not improve after 4 months, we should consider covering therapy or atropine depression therapy.

       (2) Principles of spectacle correction

       ¢Ù All ametropia should be corrected as soon as possible in children under 12 years old, and their binocular vision should be consolidated to prevent the occurrence and development of strabismus and amblyopia.

       ¢Ú Adult patients with binocular vision can be corrected.

       ¢Û Young people with alternate visual acuity and visual fatigue can be completely corrected, but for the elderly, no visual fatigue can be corrected completely.

       ¢Ü At the same time, careful examination of ocular muscle balance should be carried out at the same time. ¢Ý The correction effect of contact lens is better than that of frame glasses. If conditions permit, contact lens can be selected.

       2. Covering therapy and drug therapy

       Anisometropic amblyopia is not only corrected by wearing glasses, but also covered treatment and atropine depression therapy. The principle of occlusion in the treatment of anisometropic amblyopia is to reduce or eliminate the inhibitory effect on amblyopia by covering healthy or better eyes, so as to increase the use opportunity of amblyopia, so as to improve the visual acuity of amblyopia.

       3. Contact lens

       At present, the methods of correcting binocular anisometropia include frame glasses, RGP, refractive surgery, etc. the effect of corneal contact lens on correcting anisometropia is the most obvious. Because the lens is worn on the surface of the cornea, the size of the lens is close to that of the emmetropia, and there is no prism effect when the eyeball rotates. Therefore, it can correct the refractive reference of medium height.

       Some studies have found that the time and degree of stereopsis development of RGP are better than those of traditional frame glasses. The reason may be that the use of contact lens to correct ametropia will not cause the special optical deficiency when wearing frame glasses.

       In particular, when the hyperopia is fully corrected, the blurred image on the retina becomes clear, the abnormal visual stimulation is transformed into normal visual stimulation, and the form deprivation of amblyopia is relieved. The function of visual pathway and visual cortex can be fully developed and restored to normal, which provides conditions for the development of stereopsis.

       4. Refractive surgery

       Corneal refractive surgery emerged in the 1990s. It was found that the vision and binocular visual function of anisometropic amblyopia patients after surgery were better than those who used traditional frame glasses and contact lenses. At present, PRK, LASIK and LASEK are the most commonly used excimer laser surgery in the treatment of anisometropia.

       The effect of excimer laser surgery in the treatment of anisometropia is to reduce the diopter and refractive index of one eye or both eyes, which is more in line with the physiological state of the eye, so as to enhance the fusion function. The operation directly affects the cornea, avoids optical aberration, improves vision and stereopsis.

       It’s not a dime to do with Persia. Different breeds of cats have different eyes. In fact, the color of cat’s eyes is not much. Generally, they are yellow, blue, amber, purple steel, green and light brown. There are some differences in color.

       The reason for the difference in the color of cat’s eyes is that different species of cats, or cats of different individuals in the same breed, have different ability to absorb and store pigment. Different pigments are deposited on the retina of all kinds of cats, which makes their retinas have different colors. The color of cat’s eye we see is actually to see the cat’s retina directly through the transparent cornea These colors on the. In cats of different breeds or individuals, there is a certain correlation between the deposition of pigment in the retina and the deposition of pigment in the hair follicle of skin. Therefore, there is a certain correlation between the color of cat’s eyes and the color of cat’s fur. For example, flower cats definitely don’t have blue eyes. Black cats have green eyes, while white cats with long hair have blue eyes, sometimes with different colors. We don’t know the actual effect of the color of cat’s eye on the cat itself. However, when people evaluate the color of cat’s eye, the clearer and more transparent the cat’s eye is, the purer the color is, the deeper the color is and the more precious stones are felt.

       In addition, the color of cat’s eyes is one of the important basis to identify purebred cats. Some purebred cats have fixed eye color. For example, pure Siamese and Himalayan cats must have blue eyes. If the appearance of the whole cat is the same as that of a purebred cat, but the color of its eyes does not match the eye color of the purebred cat, it means that the cat has mixed blood of other breeds.

       The eye color of Persian cat depends on the color of its fur. It is generally believed that the eye color of Persian cat includes blue, green, copper, gold, amber, strange color, and two eyes have different colors (namely mandarin duck eyes). The coat color of Persian cat with mandarin duck eyes is usually white with green, amber and golden eyes, and generally belongs to the silver gray color system. The purer and darker the color of all kinds of eyes is better, and the color uniformity of two eyes is better
