Soft corneal contact lenses, the main advantage is that they are more comfortable, but also in the daily cleaning and maintenance, as well as contact lens wear have a certain degree of convenience. Soft contact lenses are available in daily, monthly, semi-annual, and annual, and if you choose daily, you don’t need to use a care solution, it’s just easier to use one a day. The monthly and semi-annual contact lenses require the use of care solution, but they are relatively easy to wear in terms of requirements. However, the disadvantage of soft contact lenses is that they have poor oxygen permeability, and their material limitations have a certain gap in oxygen penetration compared to rigid corneal contact lenses. For people with sensitive corneas, wearing soft contact lenses may lead to corneal clouding due to lack of oxygen, which may require discontinuation of wear for restorative treatment until the cornea is completely healed.
