Come on, do you really think that if someone had syphilis, he would advertise the fact with tinted eyeglasses?
Tinted eyeglasses are not new. In the eighteenth century, some people wore blue, green, amber, and amethyst lenses to protect their eyes from the sun’s glare. They did not indicate a medical problem.
Medical books of the time make no mention of colored lenses in treating syphilis. In Treatise of the Venereal Disease (1789), the author notes correctly that syphilis could cause eye inflammation but offers no specific treatment. In his Observations Concerning the Prevention and Cure of the Venereal Disease (1796), William Buchan recommends blistering plasters applied to the temples or behind the ears to reduce some of the symptoms. No primary reference to the connection between colored lenses and syphilis has been found.
