The 2.5 * glasses type near and far binocular vision aid consists of two 2.5 * monocular telescope vision aids installed on glasses frames to observe distant targets.
A convex lens with a picture frame with 5 different magnifications (2×, 3×, 4×, 5×, 6×) is added to form a microscopic system by adding the convex lens in front of the monocular telescope's visual aid object lens, which further magnifies close objects to form a high magnifier (capable of magnifying 15×) to meet the needs of amblyopia groups.
It is suitable for medical treatment, biology, clocks, machinery, printing, instrument maintenance, and other industries. Or for assisting vision of amblyopia groups and observation of distant and near objects.
Each pair of glasses-type near and far binocular vision aids is equipped with a leather cover, a hanging rope, and an eyepatch.
After installing the multiplier, rotate the lens barrel clockwise (counterclockwise) to continuously change the magnification and observe the object.
