During the late 19th century the United States Army,Boer Defense Forces and British Imperial Arny, issued eyeglasses with tinted orange/ brown lenses. These were semi- textured with a central smooth section of the lens. They were provided to Signal Corps Personnel to accompany the Heliograph, as direct focus on the eye of the sun's rays was necessary to operate the device. the frames were silvered.PintoMars (talk) 03:18, 19 March 2014 (UTC)

UV therapy in the 19th c[edit]

It should maybe be noted in the history section that sunglasses were widely used by doctors and patients in the 19th century who participated in UV therapy. — Preceding unsigned comment added by Brianshapiro (talkcontribs) 01:56, 23 April 2014‎

In recent years there has grown up a most pernicious and entirely unfounded belief that light is bad for the eyes. An organ which, for some scores of millions of years, has been adapting itself very successfully to sunshine of all degrees of intensity, is now supposed to be incapable of tolerating daylight without the mitigating intervention of tinted goggles, or lamplight, except when diffused through ground glass or reflected from the ceiling. This extraordinary notion that the organ of light perception is unfitted to stand light has become popular only in the last twenty years or so. Before the war of 1914 it was, I remember, the rarest thing to see anyone wearing dark glasses. As a small boy, I would look at a be-goggled man or woman with that mixture of awed sympathy and rather macabre curiosity which children reserve for those afflicted with any kind of unusual or disfiguring physical handicap. Today, all that is changed. The wearing of black spectacles has become not merely common, but creditable. Just how creditable is proved by the fact that the girls in bathing suits, represented on the covers of fashion magazines in summer time, invariably wear goggles. Black glasses have ceased to be the badge of the afflicted, and are now compatible with youth, smartness and sex appeal. This fantastic craze for blacking out the eyes had its origin in certain medical circles, where a panic terror of the ultra-violet radiations in ordinary sunlight developed about a generation back; it has been fostered and popularized by the manufacturers and vendors of coloured glass and celluloid spectacle frames. Their propaganda has been effective. In the Western world, millions of people now wear dark glasses, not merely on the beach, or when driving their cars, but even at dusk, or in the dim-lit corridors of public buildings. Needless to say, the more they wear them, the weaker their eyes become and the greater their need for ' protection' from the light. One can acquire an addiction to goggles, just as one can acquire an addiction to tobacco or alcohol.

Standards section error[edit]

Issue

The statement:

"There is no rating for transmittance protection for radiation of up to 400 nm ("UV400"), as required in other countries (incl. the United States) and recommended by experts."[10]

appears contradicted in the following paragraph, reading:

"The U.S. standard is ANSI Z80.3-2001, which includes three transmittance categories. According to the ANSI Z80.3-2001 standard, the lens should have a UVB (280 to 315 nm) transmittance of no more than one per cent and a UVA (315 to 380 nm) transmittance of no more than 0.3 times the visual light transmittance."

Solution

Rewrite the first quote as, "There is no rating for transmittance protection for radiation of up to 400 nm ("UV400"), as required in other countries and recommended by experts."[10] Nick Nardozzi (talk) 18:51, 23 November 2014 (UTC)

With rising awareness of the Blue Light Threat from natural and artificial light sources, there is patented technology to effectively filter blue light. Based on the human body's own defenses, Melanin + Ocular Lens Pigment is an adjunct perfected by Dr. James Gallas, with global exclusivity provided to "TrueBlue Lenses". Although there are other lenses that claim to protect from blue light, the TrueBlue lens filters the blue light spectrum like no other lens for superior protection against veiled glare, benefiting the lens and retina of the eye.
