A magnification device including a housing having a distal open end and a proximal open end is disclosed. The housing includes an optical system including one or more objective lenses adjacent the distal open end, and one or more eye lenses adjacent the proximal open end, the optical system produced a desired level of magnification; and a filtering system having first filter selectively filtering a first group of wavelengths and a second filter selective filtering a second group of wavelengths. The first and second filters having an optical density selected based on a magnification level of the optical system. A vision enhancing assembly including a carrier device and one or more magnification devices coupled to the carrier device is also disclosed, wherein the magnification devices include filters that have optical densities based on a magnification level.

In assembling a binocular loupe device, a loupe of the binocular loupe device is attached to an appropriate position at a correct angle according to a pupil position of a user in a near vision state. A rectangular, transparent measurement assisting plate fixed to a frame before attachment of a loupe is worn by a user, and the face of the user in a near vision state is photographed by a camera from a work object point P to obtain a first image. The first image is subjected to arithmetic processing by a computer to measure, on the first image, coordinate positions of respective four vertexes of the measurement assisting plate and coordinate positions of respective left and right pupils of the user in the near vision state, and determines the loupe attachment position and/or loupe attachment angle on a plane of the plate member from the measured coordinate positions.

A dermatoscope device is provided. The dermatoscope device includes an optical tube structure including an optical unit, which is provided to allow an observer to enlarge and inspect an observation target, and a light emitting unit which irradiates light to the observation target to be enlarged and inspected through the optical unit, a control module to control a form of irradiating the light through the optical unit, and a housing having the optical tube structure and the control module embedded therein.

A deep-viewing coaxial illuminator accessory that may be easily reversibly attached to commercial high-brightness, focusable-beam flashlights to provide shadow-free viewing of subject matter up to 20 ft or more away is disclosed. A miniature companion telescopic magnifier for optional use with the coaxial illuminator that provides erect-image magnified viewing and may be easily reversibly attached to the illuminator is described.

According to an exemplary embodiment, a loupe attachment for glasses may be provided. The loupe attachment may include a loupe and a number of optical devices such as mirrors or prisms. The loupe and the optical devices may be connected to eyeglasses and be positioned as desired. The loupe and the optical device may be connected to the glasses on number of locations and the relative position of the loupe and optical devices in the trajectory of light may be modified. According to a second exemplary embodiment, loupes may be rigidly connected to eyeglasses and a number of optical elements may be rigidly or rotatably connected to the front end of the loupe so as to reflect the field of view situated at an angle from the loupe viewing direction.

A magnifier is the only product of its kind that offers a completely hands-free scope option that requires little to no adjustment after set-up. This unprecedented product is uniquely designed with high-grade magnifying lenses that cover large viewing areas, possesses durable LED lights to deliver operational excellence and glass strength ranging from 2 to 3 magnification to help with clarity for the viewer during utilization.
