Background

The eye is the most important visual organ of human and animals, and is approximately spherical, and the eyeball covers tissues such as eyeball wall, eye cavity and contents, nerves, blood vessels and the like. The average pressure exerted by the intraocular contents on the eyeball wall is intraocular pressure, and the intraocular pressure of a normal person is stabilized at 11-12 mmHg and fluctuates along with time. Under normal conditions, intraocular pressure fluctuates by 2-6 mmHg within one day, and the difference between two eyes can be within 4mmHg, but intraocular pressure changes excessively and is harmful to the eyes, and intraocular pressure is too high and then compresses optic nerves, and intraocular pressure is too low to cause eyeball deformation. Blinding eye diseases such as glaucoma and the like have invisibility, early diagnosis is a key for treatment, and intraocular pressure measurement and fundus examination are particularly important in ophthalmic examinations such as glaucoma and the like. In recent years, the number of people suffering from eye diseases is increasing, and nearly eighty million people worldwide are expected to suffer from glaucoma in 2020, and effective diagnosis is extremely important.

The wearable ophthalmic detection instrument in the prior art is generally fixedly arranged, and because the nose bridge of different patients is highly inconsistent, when the wearable ophthalmic detection instrument is worn, the detection is not high in the fitting degree of the eyes, and the detection accuracy is not high.
