The ultra-fine soft light area has both the functions of prevention and control and visual transition. The outer side is arranged with an alternating pattern of micro-lenses and micro-structured cylindrical lenses. Due to the reduced area, the number of micro-structures per unit area increases, and the filling rate of the functional area of the entire lens rises. At the same time, the micro-structures make it difficult for the brain to detect, and the visual perception is not easily disturbed. With the three types of micro-structures, as the eyes move during visual activities, the signals entering the eyes always maintain a dynamic change, thus realizing the improvement of the visual experience while ensuring the prevention and control effect and imaging intervention of itself, which is more conducive to long-term wearing.

[0023] Example 1: Fixed negative defocus design, better wearing effect for exophoria population

[0024] The diopter range of the ultra - micro lens area 6 is - 0.25D to - 10.00D, with a fixed negative defocus setting. The diopter range of the annular ultra - micro cylindrical lens 7 is - 0.25DC to - 12.00DC, with a fixed negative defocus setting.

[0025] For example: The unified diopter of each ultra - micro lens in the ultra - micro lens area is: - 6.00D, and the diopter of each annular cylindrical lens in the toric lens area is: - 10.00DC.

[0026] Example 2: Fixed positive defocus design, better wearing effect for esophoria population

[0027] The diopter range of the ultra - micro lens area 6 is + 0.25D to + 10.00D, with a fixed positive defocus setting. The diopter range of the annular ultra - micro cylindrical lens 7 is + 0.25DC to + 12.00DC, with a fixed positive defocus setting.

[0028] For example: The unified diopter of each ultra - micro lens in the ultra - micro lens area is: + 6.00D, and the diopter of each annular cylindrical lens in the toric lens area is: + 10.00DC.

[0029] Example 3: Negative defocus gradient design, enhancing the prevention and control effect in the central area.

[0030] The diopter range of the ultra - micro lens area 6 is - 0.25D to - 10.00D, with the negative defocus increasing by + 0.12D for each group from the inside out.

The diopter of the innermost first - group ultra - micro lens area is - 8.00D, the second - group ultra - micro lens area is - 7.82D, and so on, with a change of + 0.12D for each group.

[0032] The diopter of the annular ultra - micro cylindrical lens area decreases gradually from the inside out for each group. The diopter of the innermost first - group annular ultra - micro cylindrical lens area is - 10.00DC, the second - group annular ultra - micro cylindrical lens area is - 9.50DC, and so on, with a change of + 0.50DC for each group.

The luminosity of the first group in the innermost circle of the annular ultra - micro cylindrical lens area is +10.00DC, the luminosity of the second group is +9.50DC, and so on, with a change of -0.50DC for each group.

[0037] Example 5: The positive and negative defocus of the micro - lenses are arranged alternately to enhance the dynamic prevention and control effect.

[0038] The luminosity of the ultra - micro lens area 6 is set in the range of +10.00D to -10.00D, the luminosity of the annular ultra - micro cylindrical lens 7 is set in the range of +12.00DC to -12.00DC, and the ultra - micro lens area 6 and the annular ultra - micro cylindrical lens 7 are set to change alternately between positive and negative from the inside to the outside.

[0039] For example, the luminosity of each group in the ultra - micro lens area is arranged alternately with positive and negative defocus from the inside to the outside. The luminosity of the first group in the innermost circle of the ultra - micro lens area is -8.00D, the luminosity of the second group is +8.00D, and so on, with an alternating change, and it can also be positive first and then negative.

[0040] The luminosity of each group in the annular ultra - micro cylindrical lens area is arranged alternately with positive and negative defocus from the inside to the outside. The luminosity of the first group in the innermost circle of the annular ultra - micro cylindrical lens area is -10.00DC, the luminosity of the second group is +10.00DC, and so on, with an alternating change, and it can also be positive first and then negative.
