A Detailed Overview of the Eyeglasses Manufacturing Process
While you may not think there is much that goes into making a pair of prescription eyeglasses, the crafting process is more complex than you'd imagine. Modern glasses are customized to the wearer's needs and are capable of being able to accommodate a wide variety of prescription needs. If you're curious about the process used to design eyeglasses or you are trying to better understand how to choose glasses that best fit your style and lifestyle, this guide explains how prescription glasses are manufactured.
The Components of Prescription Eyeglasses
Understanding the different parts of eyeglasses can help you choose a pair that is the most comfortable, stylish, and functional for your needs. While the main components of every pair of glasses include the frame and the lenses, you can break these categories down even further.
Frames
Eyeglass frames serve the main function of holding the lenses in place and staying secured on the wearer's head. The front section of the frame includes the rims which surround and hold each lens. A bridge piece connects both lenses to each other, and the end pieces on each outer section of the rims allow the front of the frame to be attached to the arms, or temples, with hinges. The temples of glasses can be made in varying lengths, and they include an angled tip to keep them from falling off.
Frame Materials
There are many different types of materials used to make the frames on prescription eyeglasses, which vary in durability, flexibility, and affordability. While metals and plastics are most often used for glasses frames, there are some less common materials that may be used, such as wood. Several of the most widely used metal frame types include:
Nylon: A durable, lightweight plastic frame material often used for safety glasses or sports frames.
Aluminum: A popular metal used for its minimal weight and anti-corrosion properties.
Titanium: A pricier alternative to aluminum, titanium glasses are also lightweight, resistant to corrosion, and incredibly flexible.
Stainless Steel: These glasses are made from a combination of metals including manganese, chromium, and nickel. They are an affordable option for metal frames while remaining durable and lightweight. However, some people have an allergy to nickel or chromates.
Flexon: Made from a blend of titanium and nickel, Flexon frames boast incredibly flexibility and have the ability to maintain their shape when bent.
Cellulose Acetate: Affordable and customizable, acetate glasses are made from plant-based, hypoallergenic plastic. This material can be made in almost any color combination, with varying levels of transparency and finishes.
