  • the spatial frequency is the number of cycles of a sine wave grating contained in an angular range of 1° centered on the position of the eye (e.g., the eye point or the center of rotation).
  • the width of the lines constituting the characters is regarded as half the wavelength of the sine wave, and the spatial frequency of the visual target is calculated. Note that in Snellen letters, Sloan letters, the letter “E” on an E chart, and the letter “C” on a Landolt ring, the width of the lines constituting the characters and the spacing between the lines have constant values.
  • the contrast sensitivity to a visual target varies depending on the spatial frequency of the visual target.
  • the contrast C of the visual target can be expressed, for example, by the following formula (1).
  • a target with black characters drawn on a white background if the luminance of the black part (minimum luminance Lmin) is 0, the contrast C of the target is 1 according to formula (1).
  • the contrast C of the target is 0.75 according to formula (1). Note that the luminance is expressed as a gradation value of 256 gradations as an example.
  • the minimum contrast of the target that can be recognized by the wearer is called the contrast threshold.
  • Contrast sensitivity is the reciprocal of the contrast threshold. For example, if the contrast threshold is 0.1, the contrast sensitivity is 10. In addition, the contrast sensitivity is a different value depending on the spatial frequency of the target. Generally, if the spatial frequency of the target is 8 [cycles/deg] or more, the lower the spatial frequency, the higher the contrast sensitivity. It is also known that there are individual differences in contrast sensitivity to a specific spatial frequency and in differences in contrast sensitivity to multiple spatial frequencies.
  • the spatial frequency decreases as the distance to the optotype decreases. If a spectacle lens wearer has a higher contrast sensitivity to an optotype with a low spatial frequency compared to the contrast sensitivity to an optotype with a high spatial frequency, and can clearly see a closer object (visual object) through the spectacle lens, the contrast sensitivity to the visual object will be higher, and higher visibility will be possible.
  • the add power at a specified position in the progressive portion between the distance portion and the near portion is designed to be higher than the standard add power. With this design, a closer visual object can be clearly seen through the progressive portion of the spectacle lens, and the contrast sensitivity to the visual object will be higher, and higher visibility will be possible. Therefore, by changing the distribution of the add power in the progressive portion of the spectacle lens according to the change in the wearer's contrast sensitivity corresponding to the change in the spatial frequency of the visual object, an appropriate spectacle lens can be designed.
