What reading level is The Pathological Effects of Radiant Energy On the Eye An Experimental Investiga book?
To quickly assess the difficulty of the text, read a short excerpt:
Finally, the possibility of abiotic action is ruled out by the fact that it is impossible for abiotic waves to pass through the entire thickness of the lid, if only on account of its rich vascularization. This objection does not apply to possible heat effects produced by visible or infrared rays, but in this case it would be necessary to assume exposure of the eyelid to direct sunlight for considerable periods of time as well as special sensitiveness of the conjunctiva to heat, neither of which... conditions seems possible.
EFFECTS OF RADIANT ENERGY ON THE EYE. 715 SENILE CATARACT.
The theory has been advanced (see page 780) that senile cataract is due to exposure of the lens to daylight, particularly that from the sky. This is based solely on the fact that the cataractous changes usually begin in the lower part of the lens. It is undoubtedly true that the changes do first appear below, but as a rule they are so far below that they are in a portion of the lens completely shaded by the iris.
