An Overview of Buying the Right Eyeglasses

Nowadays, you can find all sorts of eyeglasses at the stores. The frames of the eyeglasses can be made from different kinds of plastic and metal. Special eyeglasses frames are made from wood, and buffalo horn. Wood and buffalo horn eyeglasses frames are stiffer so they are harder to adjust. However, they provide appealing looks for women.

Some people are allergic to the eyeglasses frames. Besides the frame, the nose pad can also cause irritation on the skin. If you suffer from skin irritation, you have to inform your optician. The optician will recommend the right type of eyeglasses for you. If your metal frame is causing irritation on your skin, there is a high possibility that it contains nickel. There are other types of metals that can cause skin irritation such as copper, beryllium, zinc, and aluminium. The allergic materials in the nose pad are silicone and acetate. Sometimes, polyvinyl chloride (PVC) nose pads can also cause skin allergy. If you don’t want your skin to suffer from irritation, you can choose frames that are made from propionate, polyamide and nylon.

Before shopping for the cheap eyeglasses, you need to know the prescription power of your eyes. If it had been a long time since you take the eye test, you should visit the local optometrist. The optometrist will ask you to see the alphabetical words in different sizes. When sitting for the eye test, you should not strain your eyes. If you strain your eye to see the word, the prescription won’t be accurate. You need an accurate prescription so that you can purchase the right lens. The optometrist should explain the terms on the prescription to you if you don’t understand.

You can ask the optometrist to measure the papillary distance. The papillary distance is the distance between the centers of the eyes’ pupils. You can use a ruler to measure the papillary distance yourself if the optometrist don’t want to measure it for you. However, it is recommended that you ask the local optometrist to measure the papillary distance since he is more experienced. When measuring the papillary distance, make sure you look at the mirror. After that, you should hold the ruler in between the pupils and record down the measurement. If a friend is helping you to measure the papillary distance, you should sit down on a chair. In this way, your friend will be able to take accurate measurement of the papillary distance.
