The type of contact lenses is determined according to your age, diopter, and lifestyle habits. If you have a high cylindrical diopter, high spherical diopter, or certain corneal diseases (keratoconus), only semi-hard lenses are an option. Often, for nearsighted people of younger age, who are still expected to experience an increase in diopter, wearing semi-hard lenses is recommended to start with, although we know today that there is no scientific evidence that they slow down the progression of diopter. In most other cases, i.e., almost always when possible, the use of soft lenses is recommended. They are more comfortable and simpler to wear, and there’s no need for gradual adjustment to them, as is the case with semi-hard lenses. Soft contact lenses are prescribed much more frequently in practice. Today, there is a large number of manufacturers and types of soft contact lenses on the market. According to the recommended wearing time, they are divided into daily, biweekly, monthly, quarterly, and annual lenses. More and more often, daily and biweekly lenses are prescribed because they have excellent permeability to oxygen and water, and due to the short wearing period and frequent replacement, the possibility of developing an infection is reduced.
