As they grow older, the world of middle-aged and elderly people becomes more and more difficult, they need to squint hard to see things, reading books and newspapers are no longer as easy as when they were young, and those details of life that we don't take for granted and are accustomed to may bring them many difficulties, and the world of myopia and presbyopia is even more difficult. Many times, it is difficult to see far and near, and it is often necessary to change two pairs of glasses to meet daily needs.
In this regard, Hu Yue, director of the Department of Optometry and Pediatric Ophthalmology of Aier Ophthalmology Xiangtan Region, said: When I was young, my eyes had myopia problems, and after the age of 40, there was presbyopia, resulting in blurred vision, and when I couldn't see clearly, I could choose to wear asymptotic multifocal lenses to avoid the trouble of frequently taking off and using two glasses to see clearly.

What are gradient focus glasses?
Gradient focus glasses have four viewing areas: farsightedness, myopia, transition, and aberration, which can be met by seeing far and near. Progressive multifocal lenses are referred to as multifocal lenses, that is, a pair of glasses with multiple gradient optical focus from top to bottom, which can meet the needs of the human eye to see different objects clearly from far to near.
Why do you want to go to an eye hospital for glasses?
Director Hu Yue explained: Gradient focus glasses have high requirements for the selection of frames, interpupillary distance and other spectacle parameters and the accuracy of refraction, and the hospital will provide a full-range solution with the core of fitting gradient focus lenses through a series of examinations. Gradient focus glasses, which can see clearly, from far to mid and near, have high requirements for the accuracy of various glasses parameters.
The ophthalmology hospital will conduct professional medical optometry for the optician, including the prescription of optometry, eye position, accommodative power, binocular monovision function, convergence function, binocular adjustment balance, identification of the dominant eye, etc., and finally issue a scientific optometry prescription based on the above conditions to carry out personalized customized glasses. In addition, going to a professional eye hospital for glasses will also conduct a "micro-physical examination" of the eyes to check for other eye diseases, so as to achieve early detection and early detection of eye diseases.
Multifocal lenses are becoming more and more mature, no longer like in the past is the exclusive privilege of special groups, progressive multifocal lenses are tailor-made, according to each person's power and make lenses, so that the power of reading glasses and the power of the eyes are completely consistent, in addition to the face shape characteristics, such as interpupillary distance, pupil height and other matching, after wearing more comfortable, at the same time can achieve the effect of clear distance, comfortable to wear, beautiful and good-looking.
