Description

Contact lenses and contact lens products

The present invention relates to a contact lens and a contact lens product, in particular to a contact lens and a contact lens product that can effectively improve wearing comfort.

The outermost edge area of conventional contact lenses is not well designed, and the outer edge of poorly designed contact lenses has a sharp structure, which will obviously affect the comfort of wearing contact lenses. Furthermore, when the contact lens touches the sensitive cornea, it is easy to feel uncomfortable in the early stage of wearing, and it is more likely to cause the outer surface of the cornea to deform after being worn for a long time, and even damage the corneal structure.

According to the present invention, a contact lens is provided, which includes a central area, an annular area, a peripheral area, and a rounded area in sequence from the center to the outside. The central area contains a central point of the contact lens. The ring area surrounds the central area. The peripheral zone surrounds the annular zone. The rounded area surrounds the peripheral area, and the rounded area includes a front surface, a rounded surface, and a back surface, wherein the rounded surface is adjacent to the front surface and the back surface, and the back surface includes at least one supporting back surface. Among them, the radius of curvature of the rounded surface in the rounded area is RE, and the radius of curvature of the front surface in the rounded area is RF. At least one supporting back surface of the rounded surface is the first supporting back surface, and the radius of curvature of the first supporting back surface is RB1s, which satisfies the following conditions:

The contact lens is immersed in a buffer solution. The contact lens and the buffer solution are contained in the package. The buffer solution contains a beneficial agent, a wetting agent, a pigment or a myopia control agent.

Thereby, the contact lens of the present invention is designed to continuously adjoin the rounded area including at least three surfaces with different radii of curvature through the outermost area of the contact lens, and the rounded area has multiple curvatures of the front surface, the rounded surface and the back surface. The optimal radius of curvature and the configuration of the surface area between the radii can effectively reduce the pressure of the contact lens attached to the cornea to avoid the possibility of damage to the corneal structure, thereby improving the wearing comfort of the user, and helping Reduce the difficulty of designing and manufacturing contact lenses.
