As we get older, we all start to get wrinkles and gray hair. And the eyes will also appear aging, the most common manifestation of which is "presbyopia." In the modern society where everyone uses their eyes highly, the age of presbyopia is gradually advancing. In order to strengthen everyone's understanding of presbyopia and timely selection of appropriate glasses in the eyeglass mart to protect eye health, our newspaper invited the national level (senior) optometry technician Fei Cuihua to answer relevant questions for everyone.

Presbyopia myopia does not necessarily offset early detection and early prescription

Myopia will not presbyopia, myopia and presbyopia offset each other, vision can be restored as before, young people will not presbyopia...... There are a lot of misconceptions about presbyopia.

Myopia and presbyopia are two different things. From the cause, myopia is mostly because the front and back eye axis of the eyeball is too long to cause blurred when looking at the distance, presbyopia is mainly due to the elasticity of the lens in the eyeball decreases with age, resulting in blurred when looking at the near, myopic people to a certain age will still occur presbyopia. As for whether the two can be offset, but also by the eye distance and the specific degree, only in the myopia degree and presbyopia degree is consistent, see the near degree of each other do not need to match glasses, this situation is very rare.

Presbyopia is not a disease of old age. With the emergence of electronic and digital products, the age of presbyopia is gradually younger, and there is a precedent for presbyopia in the 30s and 40s. When these symptoms occur, it is necessary to pay attention to: difficulty in seeing objects at a close distance, holding books or electronic devices far away to see the text, unconsciously carrying the reading object further away; Frequent visual fatigue, habitual squinting to see the items in front of you, looking at the near time for a long time will be eye distension, eye acid, and even headache and irritability.

In the case of presbyopia, the strong support to see things will increase eye fatigue, resulting in a higher degree. Therefore, when these symptoms occur, it is necessary to carry out a professional examination in time and choose the right glasses for yourself.

Progressive film to solve the problem of picking the mirror near and far at the same time

Traditional reading glasses are very troublesome to use, you need to put them on to see close, you need to take them off to see far, the glasses are constantly zoomed, and frequent picking and wearing is easy to cause eye strain. If you have presbyopia, need to see both near and far, and need two pairs of glasses to switch back and forth, consider this amazing lens - progressive tablet.

Progressive lenses, also known as progressive multifocal lenses, use a step-by-step approach so that the diopter changes on the same lens. This kind of lens is used to see far above, and the bottom is used to see close, which can meet the three different luminosity of the distance, medium distance and near distance required by the wearer at the same time, and the appearance is the same as the normal myopia mirror, which is very beautiful.

The role of different partitions is different, so the relative position of the lens and the eye is very important, otherwise the position of the corresponding area changes, it is easy to appear fuzzy dizziness and other symptoms, thus affecting the visual experience of the wearer. This also makes the progressive tablet to the pupil distance pupil high matching parameters and the accuracy of the optometry is very high, need a professional optometrist for matching.
