Abstract: The invention relates to color-changing eye drops for early screening Alzheimer's disease and an application thereof. The color-changing eye drop for early screening Alzheimer's disease comprises 1 pg/ml to 10 ng/ml of A?42 aptamer-gold nanoparticles (AuNPs) and a pharmaceutically acceptable carrier or vehicle thereof, which can be used to mix with a tear sample of a test subject to analyze a color change of the color-changing eye drop for determining the concentration proportion of A?40:A?42 contained in the tear sample of the test subject.

Abstract: A method for measuring two pupils includes a number of steps. A first visible light beam and a first invisible light beam are emitted toward a right eye. A second visible light beam and a second invisible light beam are emitted toward a left eye. The light beams reflected from the right eye and the left eye are received by an optical unit, and the first invisible light beam and the second invisible light beam are guided to an imaging unit by the optical unit. Images of the right eye and the left eye are respectively recorded through the first invisible light and the second invisible light beam propagated from the optical unit.

Abstract: The present invention discloses a portable pupil detection device with multiband stimulating light and infrared illumination, which comprises at least one pupil detection module for detecting the variation of the pupil of the testee. Each pupil detection module includes an illuminating light source emitting invisible light beams; a stimulating light source emitting visible light beams; at least one beamsplitter corresponding to the illuminating light source, the stimulating light source and an eye of the testee, cooperating with the illuminating light source and the eye to form a first optical path, and cooperating with the stimulating light source and the eye to form a second optical path; a lens corresponding to the beamsplitter and receiving the invisible light beams sent out by the beamsplitter to form an image of the eye; and an imaging element receiving the image of the eye from the lens.
