Who invented safety glasses

Workers in various fields realized that wearing safety glasses is a must to protect their health. In the s, polycarbonate has replaced laminated glass in all safety lenses as a much stronger and lighter material. Today, safety eyewear comes in a wide variety of styles to fit any safety requirements or fashion trends. If you want to know more about the history of eyewear, the collections held at the Archives and Museum of Optometry include many historical artifacts such as old models of eyeglasses, contact lenses, instruments and tools.

What is the difference between regular lenses and frames and those that are safety-rated? The safety lenses are break-proof plastic lenses that protect eyes from flying debris and other risks.

Safety frames are more durable and sturdy than regular frames, are made of different shatter-resistant materials, and may include shields on the sides, depending on your specific application.

Nylon frames are used for sports eyewear because they are lightweight and flexible. While natural glass can only be tinted in a few colors, plastic eyeglass lenses are easily treated with all kinds of tints. There are 3 main types of lens materials you can choose from. According to some sources the invention of the first wearable pair of eyeglasses occurred in the 13th century in Italy. Salvino D'Armate probably invented eyeglasses in around , though various sources suggest an earlier origin.

He shared the invention of his new device with Allesandro della Spina, an Italian monk, who made it public and is often credited with inventing eyeglasses.

The first eyeglasses had frames made of metal or bone and had lenses made out of quartz because the ''opticians'' of that time didn't have the capabilities of producing flawless lenses in glass. In the 14th century, Venetian craftsmen were making "disks for the eyes"'. Italians gave these glass disks that were finely ground the name lenses because they were similar in shape to lentil beans. The earliest lenses were convex, the bulged outward in the middle, and they were used to correct far-sightedness.

Eye protection has been a benefit to mankind similar to antibiotics since before this time people would simply go blind, lose an eye, and wear an eye patch.

Pirates, who traditionally wore eye patches, did so because the violent nature of their profession meant that many of them lost or damaged their eyes. Machining, metal shaping, and wood workers are all at greater risk for eye damage due to the shards of material that fly around when working with their machines. In the s companies began making eyeglass protection specifically for these industries. Today, other industries such as medical technicians and scientists who are in danger of blood contamination from spilled or splashed samples may choose to wear eye protection.
