Talk about what is presbyopia

  Presbyopia tends to appear after the age of 40 to 45 “Unlike eye diseases such as cataracts and glaucoma, presbyopia cannot strictly speaking be called a disease. It is a physiological decrease in eye regulation caused by aging, just like everyone’s hair turns gray, and generally manifests itself as easy eye fatigue and unclear seeing up close, like a camera that can’t focus.”  The age of onset of presbyopia is generally after the age of 40 to 45, and in principle, presbyopia occurs in all people. However, the onset of presbyopia symptoms may also occur earlier or later, which is related to his previous state of accompanying farsightedness or myopia. People who were nearsighted when they were young will have a delayed onset of presbyopia because the myopia can offset some of the presbyopia, while people who were particularly sighted or farsighted when they were young will have an earlier onset of presbyopia. In addition, emotional problems such as nervousness, depression and general fatigue can also cause a decrease in eye regulation, leading to premature presbyopia.  Presbyopic glasses need to be professionally fitted and replaced regularly Presbyopia is not a disease and does not require treatment, but it can bring inconvenience to life, and the best way to reduce this inconvenience is to wear presbyopic glasses, said Dr. Chen Yueguo, but many people have misconceptions about wearing presbyopic glasses.  The best way to alleviate this inconvenience is to wear presbyopic glasses. Presbyopic glasses also have a degree, the original myopia, farsightedness and astigmatism will also affect the requirements for prescription lenses. People who have had nearsightedness or farsightedness may need two pairs of glasses, one for distance and one for near. A simpler way is to have bifocals, which means that each eyeglass lens has two degrees on it. When the vision goes up, the degree is shallower for distance viewing, and when the vision goes down, the degree is deeper for near viewing. There is also a gradual focal length presbyopic glasses, when the line of sight from the top to the bottom, the degree gradually becomes deeper, can avoid the visual jump phenomenon of bifocals.  Many elderly people like to use magnifying glasses to help read, in fact, the magnification of the magnifying glass is too high, long-term use, it will make the eyes dependent, and later it will not be easy to match the right presbyopic glasses.  In addition, the degree of presbyopia will change with age, and often deepen, generally every two or three years, presbyopic glasses also need to be changed.  Glaucoma and cataracts can also give the appearance of presbyopia The main symptoms of presbyopia are reduced vision when looking at near places (such as reading books and newspapers), easy eye fatigue, and eye swelling and pain, but when these symptoms occur, do not take it for granted that it must be presbyopia, Dr. Chen Yueguo introduced. The reason is that early glaucoma will also show eye swelling and pain, early cataracts will also show vision loss, and eye disease caused by diabetes will also have a similar performance, and this is the time to identify. If you hastily take these symptoms as a sign of presbyopia and go to an optician to pick a pair of presbyopic glasses, it is likely that you will cover up the condition and miss the time for treatment.  Laser surgery can also correct presbyopia Many white-collar workers, especially women, do not want to look old, do not want to wear presbyopic glasses prematurely, can also undergo laser surgery to correct presbyopia, similar to the principle of farsightedness correction, is through the laser method, so that the corneal shape of the eye becomes steeper. People who have had previous nearsightedness correction can still have it done as well. This procedure is technically mature, but it is not yet popular, and doctors do not recommend it as a priority, because wearing presbyopic glasses is, after all, the safest, simplest and most effective method.
