Eyestrain problems

If the rules listed above are followed, eyestrain will be minimized when peering into the microscope eyepieces with relaxed eyes (similar to observing a subject at a large distance). Many of the eyestrain problems that develop during extended periods of microscope use can be alleviated by employing video camera systems that display the specimen on a computer monitor. Without reading glasses, however, one has to accommodate to see the image clearly on t he monitor. Future microscope designs may eliminate the eyepieces altogether, substituting instead a CCD or CMOS image sensor for the classical observation tubes. The digital imaging chip will be coupled to a sophisticated software analysis package that controls image capture and storage, digital processing, and other features such as time lapse cinemicrography and real time video movies.
