A senior ophthalmology professor once said, “People always need at least one pair of glasses in their lives.” Because even if you are not nearsighted or farsighted, after the age of 40, you will need a pair of presbyopic glasses. As a physiological phenomenon, presbyopia (presbyopia) is inevitable and will be faced by everyone. So what exactly is presbyopia? Why is the common belief that people with nearsightedness do not experience presbyopia wrong? How can we get rid of the inconvenience caused by presbyopia? The normal human eye has a certain refractive power and can focus light from infinity on the retina, allowing us to perceive a clear image. When we look at close objects such as reading a book, the young eye is able to increase its refractive power and move the focus from infinity to the near target. At this time, the ciliary muscle in the eye contracts, the elastic lens becomes more convex, and the refractive power increases, a process called ocular accommodation. When age increases above 40 years, the lens gradually hardens, elasticity decreases, it cannot become convex, and the contraction of the ciliary muscle decreases, resulting in a decrease in the adjustment ability of the human eye, which cannot adjust the focal position of the eye according to the reading needs, so that patients with presbyopia can only move the book further away when reading, and the lighting should be brighter in order to see clearly, while the clarity of distant objects remains unchanged. As age increases, the ability to adjust the eyes decreases, and the symptoms of presbyopia become more and more pronounced, so that books and newspapers cannot be read clearly even if they are placed far away. Usually, the focal point of myopic eyes is very close to the eyes, so it does not require much adjustment to pull the focal point of the eyes closer when looking at near objects, and the symptoms of presbyopia appear later in these people, and they can even look closer by just taking off their nearsighted glasses. In contrast, farsighted eyes are far from the focal point of the glasses and require more adjustment to bring the eye into focus when looking at near objects than do orthoptic eyes, so these people will experience presbyopia earlier. The traditional treatment for presbyopia is to wear frame glasses, which can be monofocal, bifocal, or progressive multifocal lenses. Monofocal lenses are used only for seeing near objects and compensate for the lack of eye adjustment. The prescription is the patient’s own refractive error (nearsightedness or farsightedness) plus the additional prescription for presbyopia, which usually varies from -1.00D to -3.00D, depending on age. Bifocal lenses can meet both near and far needs, adding additional degrees of presbyopia underneath the refractive error lens, commonly known as downward additions, so that the wearer can see far through the area of their own refractive error when looking at the distance, and see near through the degree of presbyopia when looking down to read. Progressive multifocal lenses make up for the lack of bifocal lenses to see the middle distance, by slowly over-seeing the far and near two degrees, so that the wearer can get clear vision at all distances from far to near. Regardless of the type of frame, a trial fit is required, with the patient choosing the right prescription and type of glasses for their accustomed working distance. More and more presbyopes are dissatisfied with the “old look” of presbyopic glasses and are looking for ways to correct their presbyopia in a discreet way. In recent years, a number of multifocal contact lenses have emerged as a new non-surgical treatment for presbyopia. By using the principle that the pupil dilates when looking away and narrows when looking near, the periphery of the contact lens is designed for distance vision and the center is designed for near vision, thus achieving both near and far vision. Another type of monovision design using conventional contact lenses can also give some presbyopic patients satisfactory results, correcting the refractive error in the dominant eye for distance viewing, and in the non-dominant eye for near viewing, so that both eyes can get clear vision. In addition, surgical treatment methods are also favored by more and more presbyopic patients. These include cataract surgery with multifocal IOLs or adjustable IOLs, excimer laser keratomileusis, thermokeratoplasty, and conductive keratoplasty (CK). These surgical approaches have yielded satisfactory results in patients with low grade presbyopia. Therefore, presbyopia, as a natural physiological phenomenon, is a problem that everyone needs to face. Choosing a safe and effective correction method according to one’s needs and habits, after examination and fitting trial by a professional, is a sure way to improve the quality of vision and quality of life.
