Abstract: An ophthalmic treatment apparatus includes a display unit for displaying an image of a patient's eyeground, a treatment region setting unit for setting a treatment region on the basis of the image of the patient's eyeground, a treatment beam radiating unit for radiating a treatment beam to the set treatment region, a radiation density setting unit for setting radiation density of the treatment beam radiated to the set treatment region, and a control unit for controlling the treatment beam radiating unit so as to radiate the treatment beam onto the set treatment region on the basis of the set density. The treatment region setting unit divides the set treatment region into a plurality of sub-regions based on a patient's eyeground condition. The radiation density setting unit sets the radiation density of the treatment beam for each of the plurality of sub-regions.

Abstract: The present invention relates to an ophthalmic treatment apparatus and a control method therefor, the ophthalmic treatment apparatus comprising: a display unit for displaying an image of a patient's eyeground; a treatment region setting unit for setting a treatment region on the basis of the image of the patient's eyeground; a treatment light radiating unit for radiating treatment light to the set treatment region; a radiation density setting unit for setting radiation density of the treatment light radiated to the set treatment region; and a control unit for controlling the treatment light radiating unit so as to radiate the treatment light onto the set treatment region on the basis of the set density.

Abstract: A lens is provided in an asymmetric shape including at least two curved surfaces with different light distribution angles. Therefore, uniformity ratio of illuminance and coefficient of utilization (CU) may be increased while reducing dazzle. When a lighting apparatus including the lens is used as a street light, light directly incident to a driver is minimized, thereby reducing dazzle to the driver. During a night drive, brightness at a far forward position of the driver may be increased. In addition, light emitted toward a street may be increased while reducing light emitted toward a sidewalk. As a result, uniformity ratio of illuminance and coefficient of utilization (CU) may be increased. Also, light pollution may be reduced.
