Contact lenses and their products

The present invention relates to a contact lens and a contact lens product, and in particular to a contact lens and a contact lens product which can alleviate the increase of diopter away from the central area and can prevent or control myopia.

The defocus degree of traditional contact lenses with vision control function is usually designed to increase the diopter rapidly after leaving the central area. The change in diopter is drastic, which makes the wearer feel serious discomfort and cannot cooperate with the treatment for a long time. The effect of vision control is greatly reduced. Furthermore, the traditional contact lenses with positive and negative identification function are provided with small concave grooves or raised dots on the surface of the contact lenses. However, the small concave grooves are easy to break the contact lenses, and the convex The raised dots are easy to make the wearer feel a serious foreign body sensation. In addition, traditional contact lenses with vision control function cannot control the luminous flux. Too much luminous flux will easily cause the wearer to be sensitive to light, and too little luminous flux will cause blurred images. Therefore, how to improve the structure of the contact lens so that it has the function of vision control and can avoid the aforementioned defects has become the goal of the relevant industry.

Wherein the annular area includes at least one critical point value, the critical point value closest to the central point is a first critical point value, the first critical point value is a high critical point value, and the contact lens includes at least one color sample portion, the color sample portion It is a pattern with directional recognition, the maximum diopter of the annular area is PPmax, the diopter of the central area is POWC, the first critical point value is PCP1, and the maximum diameter of the central area is DiC, which meets the following conditions: 12.0 D ≤ PPmax-POWC ≤ 20.0 D; 2.0 D ≤ PCP1-POWC < 15.0 D; and 2.4 mm < DiC ≤ 4.5 mm.

According to the present invention, there is further provided a contact lens product, comprising the aforementioned contact lens and an infiltration solution, wherein the contact lens is soaked in the infiltration solution, wherein at least one of the contact lens and the infiltration solution contains a cycloplegic agent.

When PPmax-POWC satisfies the above conditions, it can provide a moderate degree of defocus, help reduce the discomfort of wearing for a long time, and provide a longer usability to achieve the purpose of myopia control.

When PCP1-POWC satisfies the above conditions, it is helpful to increase the degree of defocus appropriately and slightly, and improve the effect of preventing or controlling myopia.

It improves the comfort of wearing and helps to improve the possibility of long-term treatment.

According to the contact lens of the present invention, the central area has the function of enabling the wearer's central vision to focus clearly, but it can also reduce the wearer's myopia by 0.25 D~0.50 D depending on the situation, so as to alleviate wearing discomfort. The central zone contains the center point of the contact lens and has a constant diopter.

According to the contact lens of the present invention, the annular zone can prevent myopia or control myopia. The diameter of the annular zone can be up to 8 mm. The annular area can be provided with at least one light-blocking ring or color sample (extending from the peripheral area to the annular area).

According to the contact lens of the present invention, the peripheral region can make the contact lens adhere to the eyeball and have a supporting function. The peripheral area can be provided with at least one color sample portion or at least one light blocking ring (extending from the ring area to the peripheral area). The peripheral zone is an annular area with a diameter greater than 8 mm.

Each color sample part has a color, and the color can be selected from red, orange, yellow, green, blue, indigo, purple, black, white, silver or gold. When the color sample part is black, its maximum outer diameter is greater than 12.0 mm. If the center point of the contact lens is used as the center, the contact lens is divided horizontally and vertically into four quadrants of ABCD, and at least two of the quadrants can have repeated patterns to form symmetry, which can help achieve different quadrants but have a consistent effect of reducing stray light , when there are more repeated patterns in the four-quadrant area, the consistency of reducing stray light is better.

The calculation of the number of critical points is to take a radius line segment from the center point of the contact lens outward to the periphery of the contact lens, draw the relationship between the radius and the diopter on the radius line segment, and calculate the number of critical points in the annular area of the radius line segment.
