Green eyeshade

Have you noticed grown-ups wearing green glasses while they work on their computers or desks? They are called green eyeshades! They are also known as visors or accountant's hats. They are a device that adults use to reduce glare and eye strain while working on tasks that require a lot of concentration, such as bookkeeping or computer work.

Green eyeshades were very popular among accountants, clerks, and other professionals in the early 1900s, before computers were invented! They were made of green-tinted glass to reduce eye strain caused by bright light sources such as lamps and candles.

Green eyeshades were invented because people who worked in offices needed a way to keep the light from straining their eyes. The green color helps to reduce glare, which is the bright light that reflects off surfaces and can make it hard to see. The color was chosen because it is easy on the eyes and doesn't make things look weird.

Today, green eyeshades are not as common as before, but you may still see people using them while they work. They are not just for accountants! People who work on computers or read for long periods of time can benefit from using them. They are easy to use, and they clip onto the brim of your hat or glasses.

So, think of green eyeshades as a tool to help people work better and stay comfortable while they work. They are like sunglasses, but they are made for work, not just for looking cool!
