The present invention discloses a wearable apparatus for reading detection. The wearable apparatus worn by a user comprises a distance sensor, a judgment module, a warning device, and a regulating switch. The distance sensor senses a first status information to generate a distance data. The judgment module is for storing a predetermined value of distance and receiving the distance data. When the distance data is small than the predetermined value of distance, the judgment module generates a warning data of distance. The warning device receives the warning data of distance and then warns the user. The size of the predetermined value of distance and the warning level are adjusted by the regulating switch. Therefore the present invention can warn the user to notice the distance between the user and a reading material for efficiently preventing myopia. The present invention also can adjust the size of the predetermined value of distance and the warning level according to the user needing.本發明揭露一種用於監測閱讀之可穿戴式裝置,其被穿戴於使用者並包含有距離感測器、判斷模組、警示元件及調整開關。距離感測器感測第一狀態資訊以產生距離資料。判斷模組儲存有距離預設值,並接收距離資料。當距離資料小於距離預設值時,判斷模組產生距離警示資料。警示元件接收距離警示資料以對使用者進行警示。調整開關用以調整距離預設值之大小及警示之程度。因此,本發明可對使用者進行警示以提醒使用者注意與閱讀物間之距離,以達到預防近視的效果。本發明亦可根據使用者需求,調整所需之距離預設值大小及警示程度。1‧‧‧可穿戴式裝置10‧‧‧距離感測器22‧‧‧判斷模組30‧‧‧警示元件40‧‧‧調整開關
