Disposable contact lenses are daily disposable contact lenses. Compared with monthly, quarterly, semi-annual, annual and other types of contact lenses, they are more convenient and comfortable to wear and require no care. After wearing, they can be thrown away directly. Also relatively expensive. Although the disposable contact lens saves the lens care process and reduces the accumulation of sediment, it is also in direct contact with the cornea, which will also bring certain harm to the cornea to a certain extent. From a health point of view, no matter what type of contact lens it is, it is in direct contact with the cornea, which reduces the contact surface between the cornea and the air, which is easy to cause hypoxia of the cells in the eye, unable to carry out normal metabolism, resulting in Some foreign bodies in the eye cannot be excluded from the eye, affecting the clarity of vision. At the same time, it will reduce the resistance of the eyes and cause a variety of eye diseases to the eyes, such as keratitis, macular degeneration, corneal ulcers, etc. Compared with other types of contact lenses, disposable contact lenses may be worn for a long time, but in order to increase the contact between the eyes and the air, it is better for daily-wear contact lenses not to exceed 10 hours. However, some are made by special technology and can be worn for a longer time, such as contact lens products such as Bausch u0026 Lomb Pure Vision and Shikang Day and Night. Disposable contact lenses have more water content and thinner lenses, so there is no other type of convenience to take and wear. So disposable contact lenses are not suitable for everyone. Some people are more suitable for wearing contact lenses for a long time, such as semi-annual or annual, because their eyes are more moist or have a large diopter. Reminder: When buying contact lenses, be sure to go to a business with a 'Medical Device Product Business License' to avoid buying inferior products that damage the health of your eyes and vision.
