Inhaltsangabe

Excerpt from Eyestrain (Asthenopia)

The subject of Eyestrain has been very briefly dealt with in ophthalmic text books, and most of our knowledge of it is to be found in the scattered articles and papers by various authors, in the reviews and transactions of Societies, that have appeared from time to time.

The subject of Refraction is so intimately associated with Eyestrain that it has been found impossible, in many cases, to avoid referring to it in detail.
