Method and apparatus for preventing, controlling and/or treating eye fatigue and myopia

An apparatus for preventing and/or treating a vision disorder, comprising:

• (i) a visual stimulus or visual stimuli provided to a peripheral visual field or peripheral visual fields comprising a contrast pattern or a plurality of contrast patterns;
• (a) wherein the contrast pattern(s) is/are selected from the group consisting of:
• (A) a luminance contrast,
• (B) a translucency/transparency contrast,
• (C) a (color) spectral contrast, and
• (D) a depth contrast,
• (b) wherein the relevant spatial frequencies of a contrast pattern is between approximately 0.1 and approximately 10 cycles per degree of spatial frequencies;
• (c) wherein, the standard deviation of the relative luminance of contrast pattern(s) that has been band pass filtered for spatial frequency between approximately 0.1 and approximately 10 cycles per degree, is at least approximately 5%;
• (d) wherein the superior sections of visual stimuli are defined as sections of visual stimuli that is located higher than the primary object;
• (ii) a wearable device supporting the visual stimulus such that the contrast pattern or plurality of contrast patterns are perceived by a peripheral vision.

A method for preventing, controlling, and/or treating a vision irregularity or vision irregularities, comprising a visual stimulus or visual stimuli provided to a peripheral visual field or peripheral visual fields, wherein the visual stimulus (stimuli) comprise of a contrast pattern or a plurality of contrast patterns, thereby treating and/or preventing the vision irregularity or irregularities such as eye fatigue, and myopia,

• (i) wherein the contrast pattern(s) is (are) selected from the group consisting of:
• (a) a luminance contrast,
• (b) a translucency/transparency contrast,
• (c) a (color) spectral contrast, and
• (d) a depth contrast;
• (ii) wherein the contrast pattern(s) is (are) perceived by the eye(s) as approximately not completely behind the primary object;
• (iii) wherein the contrast pattern(s) does (do) not block the center gaze of the eye(s);
• (iv) wherein the relevant spatial frequencies of a contrast pattern are spatial frequency between approximately 0.1 and approximately 10 cycles per degree in any direction;
• (v) wherein the standard deviation of the relative luminance of contrast pattern(s) that has been band pass filtered for spatial frequency between approximately 0.1 and approximately 10 cycles per degree, is at least approximately 3.5%;
• (vi) wherein the mean relative luminance of the contrast pattern(s) is at least approximately 7%.

A method for preventing, controlling, and/or treating a vision irregularity or vision irregularities, comprising:

• (i) providing a contrast pattern or contrast patterns (the visual stimuli) to a peripheral visual field or peripheral visual fields, wherein the contrast pattern(s) is (are) selected from the group consisting of a luminance contrast, a translucency/transparency contrast, a spectral contrast, and a depth contrast;
• and
• (a) wherein the contrast pattern(s) comprises a spectral analysis profile defined by the equation:
• X/(1+10*e) with units of cycle per degree of peripheral eccentricity and/or cycle per degree of axle deviation, where X is a function, or a number, or numbers from approximately 0.5 to approximately 10 and e is angle of peripheral eccentricity expressed in radian unit, or degree of peripheral eccentricity *π/180;
• (b) wherein the contrast pattern(s) is (are) perceived by the eye(s) as approximately not completely behind the primary object;
• (c) wherein the relevant spatial frequencies of a contrast pattern are spatial frequencies between approximately 0.1 and approximately 10 cycles per degree in any direction;
• (d) wherein the standard deviation of the relative luminance of a contrast pattern (or contrast patterns) that has been band pass filtered for spatial frequency between approximately 0.1 and approximately 10 cycles per 34 degree, is at least approximately 2.5%;
• (ii) positioning the contrast pattern(s) relative to a central visual axis without blocking a center of gaze, such that the contrast pattern(s) (or visual stimuli) occupies from as low as approximately zero degree up to approximately 150 degree;
• (iii) adjusting the average visual stimulus (stimuli) angle(s) between approximately zero degree and up to approximately 90 degree;
• (iv) positioning the contrast pattern(s) (visual stimuli) at a predetermined distance from an eye;
• (v) thereby treating and/or preventing the vision irregularity.
