Abstract
A method is provided for addressing myopia progression or inclination to myopia in which the influence of accommodative lag stress on myopia is reduced or eliminated to counter eye axial length growth. User depth of focus is increased to relieve stress from overall accommodative effort and stress from accommodation and accommodative lag to retard myopia progression and enable continuous and long tem treatment by the user.
Claims33
A method of inhibiting or reducing myopic progression in a person comprising:
- enabling clear distance vision;
- and
- while maintaining clear distance vision and without introducing diffractive effects, increasing depth of focus in the person's eyes so as to enable relief of accommodative stress during near vision.
6-14. (canceled)
A method of designing a refractive lens for inhibiting or reducing myopic progression, comprising:
- determining a person's unaided eye depth of focus;
- defining a treatment lens having a continuous power distribution configured to increase the person's depth of focus when in use.
An ophthalmic lens comprising:
- an apex having distance vision correcting power;
- a power distribution increasing smoothly radially outward, from the apex to a peak power rise more positive than the distance vision correcting power;
- the power distribution having a first power at design point between the vision-correcting power and the peak power rise, the power of the distribution between the apex and design point sufficiently like in power to the distance vision correcting power to contribute to distance correction;
- the first power sufficient to create blur outside the design point;
- the power distribution power outside the design point sufficient to create a blur surrounding images on the user's fovea.
A method of inhibiting or reducing myopic progression in a person comprising:
- forming an optical surface in a person's eye, the optical surface configured to increase the person's depth of focus during use.
A method for treating myopia, comprising the steps of:
- providing a lens having a central region about the apex of the lens which yields clear distance vision, and an optical blur region immediately surrounding said central region which yields an unfocused optical image;
- such that the lens provides an induced aperture and an increased depth of focus;
- and
- applying said lens according to a protocol designed to inhibit or reduce myopic progression in the eye.
A method for treating myopia, comprising the steps of:
- providing a lens having a central region about the apex of the lens which yields clear distance vision, and a blur region immediately surrounding said central region which has a power distribution changing smoothly from said central region outwardly to a maximum power greater than an apical power, said rapidly increasing power distribution yielding an unfocused optical blur to the optical image, such that the lens provides an induced aperture and an increased depth of focus;
- and
- applying said lens according to a protocol designed to inhibit or reduce myopic progression in the eye.
A method of designing a refractive lens for inhibiting or reducing myopic progression, comprising:
- determining a person's unaided eye depth of focus;
- defining a treatment lens having a continuous power distribution configured to increase the person's depth of focus when in use;
- and
- applying said lens according to a protocol designed to inhibit or reduce myopic progression in the eye.
An method for treating myopia using an ophthalmic lens comprising:
- providing an ophthalmic lens having an apex having distance vision correcting power;
- a power distribution increasing smoothly radially outward from the apex to a peak power rise more positive than the distance vision correcting power;
- wherein the power distribution has a first power at a design point between the vision-correcting power and the peak power rise, the power of the distribution between the apex and design point being sufficiently like in power to the distance vision correcting power to contribute to distance correction;
- the first power being sufficient to create blur outside the design point;
- the power distribution power outside the design point being sufficient to create a blur surrounding images on the user's fovea;
- and applying said lens according to a protocol designed to inhibit or reduce myopic progression in the eye.
