There are many ways to correct your vision, and as society continues to evolve, the amount of time spent in close proximity to the eye is even more prolonged, and as a result, many people suffer from refractive errors. Refractive error is actually the most common type of myopia, which is easier to accept and understand in life, along with astigmatism and hyperopia. Hyperopia is in many cases due to congenital factors, i.e. a change in refractive error that occurs after birth and makes it difficult to see far and near. So it’s not that farsightedness is seeing clearly at a distance and not near, the concept has to be clarified. As for myopia, hyperopia, astigmatism, collectively referred to as refractive error in ophthalmology, correction methods currently have the following three major categories: 1, spectacle correction: first of all, the most common, we are also the highest degree of acceptance is to be equipped with framed glasses, the correction of this kind of spectacles, the history of the longer. The correction of eyeglasses can be traced back to hundreds of years ago, mankind through this discovery, through the principle of lens optics in front of the eyes, through the refractive error, the eyes can see things clearly, can help to improve the life, improve eyesight. There are many different types of framed eyeglasses, including glasses with astigmatism, glasses for distance, and glasses for near. In addition, the elderly may be involved in multifocal problems, i.e., if the elderly have both myopia and presbyopia, they may consider progressive multifocal lenses when fitting glasses to correct their eyesight in a more functional way; 2. Corneal contact lenses and keratoconus: This is a more practical method in life, i.e., the corneal contact lenses method. Corneal contact lenses are better understood as contact lenses, and there are many types of contact lenses. Ordinary contact lenses are made of soft materials, i.e., they are worn during the daytime and should be removed at night before going to bed, which is one way. Another kind is RGP, RGP is a kind of hard corneal contact lens, the material is a kind of high oxygen permeable biomaterial, the hardness is bigger than normal soft lens, the advantage is the oxygen permeability is higher, especially for the patients with big astigmatism, the wearing effect is better. Another kind of corneal reshaping lens, the main indications, is that the minor adolescent children, myopia develops faster, can improve the vision through the way of corneal reshaping lens. Keratoplasty lenses are usually worn at night before going to bed, with 8 hours of wearing time every night, and after waking up the next morning, the keratoplasty lenses will be removed, and the vision will be clearer throughout the day, thus achieving the effect of correcting the eyesight, and at the same time stopping the development of myopia. Therefore, keratoplasty lenses play a very important role in the prevention and control of myopia in young people; 3. Refractive surgery: the third way is to correct refractive errors by means of refractive surgery. Refractive surgery is subdivided into two categories, one is corneal laser surgery, and the other is eye TICL or ICL crystal implantation surgery, through which the refractive error is changed, and the principle is also very simple. If it is laser surgery, through the excimer laser or femtosecond laser, the surface of the cornea to do personalized custom, that is, how many degrees of myopia or astigmatism, the corneal surface to do a very accurate carving, the degree of set in the cornea, the operation is to restore a very clear vision. In the same way, it is important to understand that ICL or TICL lens implantation is a customized and personalized contact lens, which can be understood as a built-in contact lens. The lens is surgically implanted into the eye in such a way that the cornea does not have to be cut, nor does it have to be fitted with regular contact lenses on the surface of the cornea. By changing the refractive error through the built-in contact lens, a very good correction is also achieved. To summarize, these three methods are used in daily life, and each of them must go through a scientific, rigorous and standardized treatment process to make a treatment plan that suits the individual and his or her eyes.
