PURPOSE:To see in object brightly while seeing other bodies darkly or not glaringly by providing a transparent part which is nearly as large as the pupil to sunglasses at the position that the pupil faces. CONSTITUTION:Sunglasses which are used while put on normal spectacles one over the other are provided with transparent parts 1 and several kinds of sunglass bodies 2 which vary in distance of about + or -1m/m between both transparent parts 1 are prepared to allow the majority of people to use them. Incident light except from the transparent parts is absorbed according to the extent of coloring, etc., to eliminate glare. The transparent parts are formed right in front of the pupils, so only the object is seen brightly when an close observation is made naturally and brighter than the object seen with the naked eye.
