This invention effects a change in the accommodation of the human lens affected by presbyopia through the use of various reducing agents that change accommodative abilities of the human lens, and/or by applying energy to affect a change in the accommodative abilities of the human lens. This invention both prevents the onset of presbyopia as well as treats it. By breaking and/or preventing the formation of bonds that adhere lens fibers together causing hardening of the lens, the present invention increases the elasticity and distensibility of the lens and/or lens capsule.

Embodiments of the present invention relate to methods and pharmacological compositions to treat presbyopia in the human eye. According to the embodiments, pharmacological compositions may be applied to an eye to effect a change in the accommodative ability of the eye by the breaking and reduction of lenticular bonds in the eye that may be responsible for presbyopia. The compositions may be applied in an inactive state and subsequently be activated to achieve a therapeutic effect.

Compositions containing low doses of lipoic acid-based active agents and methods for using the same are provided. In particular, compositions containing low dose lipoic acid, lipoic acid derivatives, and lipoic acid seleno-derivatives and are provided to prevent and/or treat ocular diseases.

Embodiments of the present invention relate to a method for delivering pharmaceuticals to the lens of the eye to treat or prevent presbyopia. According to the embodiments, pharmaceuticals may be applied by providing the pharmaceuticals to the eye and promoting delivery of the pharmaceuticals into the lens capsule and/or lens fibers of the lens of the eye. Methods include iontophoresis, nano-medication, and photonic activation to deliver the pharmaceuticals to treat or prevent presbyopia.

Novel mercaptan compounds, particularly those including a photolabile protecting group, are described as well as methods of using the compounds for the prevention and treatment of ocular damage and disease.

There is provided an inexpensive fixing structure in which the fixing position of a spindle motor against a traverse chassis is fixed in the direction of the movement of an optical pickup (first direction), while can be adjusted sufficiently in the direction perpendicular thereto (second direction). In the bottom surface of the spindle motor 2, there are formed: an elongated reference hole 21, the longitudinal direction of which extends in the radial direction centering on the main shaft 4; and three screw holes 22A, 22B, and 22C spaced out in the circumferential direction centering on the main shaft 4, and in the traverse chassis 1, there are formed: a protrusion 31 adapted to be engaged with the reference hole 21 when the reference hole 21 is arranged in an elongated manner in the second direction; and elongated through holes 32A, 32B, and 32C elongated in the second direction at the positions corresponding to those of the respective screw holes 22A, 22B, and 22C. The cross-sectional width A of the protrusion 31 in the first direction is approximately the same as the width of the reference hole 21, while the cross-sectional width B in the second direction is smaller than the cross-sectional width A in the first direction.

A piezoelectric thin film can achieve a large piezoelectric displacement. A chemical composition of the piezoelectric thin film is expressed by Pb_1+a(Zr_xTi_1−x)O_3+a(0.2≦a≦0.6 and 0.50≦x≦0.62). The crystal structure of the piezoelectric thin film is a mixture of a perovskite columnar crystal region (24) having an ionic defect in which a portion of the constitutive elements of an oxygen ion, a titanium ion, and a zirconium ion is missing and a perovskite columnar crystal region (25) of stoichiometric composition having no ionic defect. This configuration allows a residual compressive stress in the crystal to be relaxed by the perovskite columnar crystal region (24) having an ionic defect, thus achieving a large piezoelectric displacement (displacement amount).

The invention discloses a driving method and driving system of a display panel and a display device. The driving method comprises the steps of receiving a first color signal, and converting the firstcolor signal into a first color space signal; obtaining a current color saturation signal S of the first color space signal and a corresponding first preset adjustment coefficient; adjusting the current color saturation signal S by using the first preset adjustment coefficient to obtain a second color saturation signal S'; calculating a third color saturation signal S'' according to the current color saturation signal S and the second color saturation signal S'; completing twice color saturation value adjustment, converting the third color saturation signal S'' into a second color space signalin an HSV system; and converting the second color space signal into a second color signal in an RGB system so as to drive the display panel. According to the invention, secondary adjustment is performed on the color saturation signal so as to improve the problem of color deviation more pertinently and more accurately.

A method of treating a human eye, generally to correct vision, and preferably in one embodiment to increase the amplitude of accommodation of the lens. The method utilizes a laser to create a desired pattern within the lens. Various patterns for treating the eye lens are also disclosed.

The invention discloses an anti-vibration device. A torque rod comprises a limiting part which is provided with a first guiding portion and a second guiding portion, wherein the first guiding portion inclines relative to the vertical direction of a vehicle body on one of two sides in the vertical direction of the vehicle body, and a reference shaft is arranged between the two sides; and the second guiding portion inclines towards the direction, opposite to the inclining direction of the first guiding portion, relative to the vertical direction of the vehicle body on the other side of the two sides. Therefore, if one side of a second inner tube body deviates from the reference shaft and contacts the limiting part, the side of the second inner tube body moves along the first guiding portion or the second guiding portion and close to and relative to the reference shaft, and the second inner tube body moves onto the reference shaft at last. As a result, the rotation of a support frame is avoided. Therefore, when the anti-vibration device of the vehicle body is combined with an engine-gearbox assembly and other bodies to be supported, relative displacement which exceeds a set maximum stroke can be reliably prevented from happening.
