Presbyopia is the eye’s decreasing accommodation capacity, i.e. its ability to increase optical power for near vision. The main reason is the loss of elasticity of the lens, caused by the natural aging process of tissues. As we get older, the cells that make up the lens continue to divide and take up more and more space in the lens capsule, making it more difficult to change the shape of the lens. The lens becomes like an over-inflated balloon. At younger ages, when refraction needs to be intensified, the muscles and ligaments on which the lens is suspended relax in a specific way, causing the lens to become more convex and convex. Patients with myopia, on the contrary, can avoid the need for reading glasses for longer, and the correction needed will depend on the degree of myopia. For example, a myope with -3 diopters does not need reading glasses, because to see well at near he needs +3 diopters, the minus with the plus compensates and as a result the patient does not need any correction at near. Such a patient is called a “happy myopic.” This is also why the question of whether surgical correction of myopia is needed for patients on the threshold of presbyopia remains open. These patients need to clearly understand that by completely eliminating myopia at a distance, in a few years they will need glasses with near-vision plus. The eyes need support, and reading glasses, which will become stronger and stronger as time passes, are an adequate support to ensure clear near vision. Today, glasses are a high-tech accessory, lightweight, strong and stylish.
