Otto Carl Friedrich Westphal (1800 – 1879) was a German physician and Geheimer Sanitätsrath (privy medical counsellor).
He was interested in environmental impacts on eyesight, including light quality, and argued that eyeglasses should be tailored to occupation.
Westphal also examined a variety of eyewashes and tinctures, and reportedly invented eye occlusion therapy[citation needed], currently used for correction of strabismus and amblyopia.
Westphal was married to Caroline Friederike Heine (1811– 1888), the daughter of a wealthy banker.
