Problems solved by technology

[0004] The present invention overcomes that the vision chart in the hospital will be framed, which makes the vision chart relatively bulky, difficult to carry, inconvenient to hang, paper-type vision charts are easy to lose, artificially fixed for a long time, and will be stained with more gray layers after outdoor use , may be discarded after one use, which wastes resources. The technical problem to be solved by the present invention is to provide a portable, easy to use outdoor vision test, which can clean the gray layer on the eye chart, and can be used repeatedly. Save resources, no need to hang or fix, and good stability Portable environmental protection vision measurement equipment for medical ophthalmology
