A Guide to the Different Types of Plastic Eyeglasses

Plastic eyeglasses are one of the most common eyeglasses on the internet. The reason it is so popular is that it is durable and won't shatter into pieces when it receives an impact. It is many times more durable than the acrylic lens. The acrylic lens is about 17% stronger than the ordinary lens. There are many types of plastic lenses you can choose from including high index, ultra high index, polycarbonate, plastic, and glass. High index lenses are thinner and lighter. Most of the people who wear glasses suffer from nearsightedness. Thick lenses are not attractive therefore, high-index lenses were created. The high index lenses can correct the vision because it bends the light properly. If your eyes are very weak, the light will need to bend at a greater angle to make you see clearly. The high-index lens is designed to bend the light at the right angle so that it can correct the vision of weaker eyes.

The ultra-high index lens is thinner than the high index lens. Because it is thinner and lighter than a high-index lens, it is more expensive. The ultra-high index lens is only more expensive by about $20 than the standard high index lens. The average cost of the standard hi-index lens is $79 while the ultra-high index lens is $99.

Polycarbonate lens is a type of high index lens that is shatterproof. It won't break easily when you drop it on the ground. An ordinary lens such as a glass lens can become shatter when it is dropped on the ground. The polycarbonate lens is almost shatterproof so it is suitable to be used in sports glasses. People who perform sports outdoors need to wear polycarbonate sports eyeglasses. When they are performing an outdoor activity, they will move around a lot. As a result, the eyeglass will drop on the ground. With the polycarbonate lens, you don't have to waste money to buy new eyeglasses. Besides, kids' eyeglasses are also made from polycarbonate lenses. Children like to run around when they are playing so parents need to buy polycarbonate glasses for them.

The plastic lens is made from plastic so it won't break easily like glass. Glass lens is made from glass so it can shatter when it is dropped on the floor. The plastic lens is slightly more expensive than a glass lens.
