Parts of Eyeglasses - Anatomy of Eyeglasses Explained

Vision is an aspect of our life that we often take for granted. For many of us, it’s not until we are told that we require vision correction that we realise how much vision improves our quality of life every day. Seeing that they are such fragile objects, we need to know the parts of eyeglasses so that if ever the need be, we are empowered to explain our requirements to an optician or we can look for replacement glasses parts by ourselves at a store.


Essentially, any pair of eyeglasses has three parts; each having its own subparts depending on the design and materials used- the front of the frame and the two arms, also known as temples.


Let’s look at the essential parts of spectacles:

1 Frame front:

This is what holds the lenses in place and defines the overall aesthetic of the pair. This can be constructed of cellulose acetate, plastic, metals such as titanium, or carbon fiber. Occasionally, it’s also referred to as the rims, which can be of 3 types:​


• Full rim - frames that surround the entire edge of the lenses. The lenses are held together by a lens groove. The frames shown here are from SmartBuy Collection.

• ​Half-rim- frames - surround the upper half of the lenses. The bottom halves are exposed and held together by a thin nylon cord, known as “supra”. The frames shown here are from Burberry.

• ​Rimless - lenses are held together by a metal bridge. Each lens is connected to the temple with a screw through the outer edge. The frames shown here are from Porche Design.

2. Lenses:

They’re the most crucial part of your prescription glasses. They’re chosen according to the prescription from your optometrist, for correcting your vision.

You can add the coating to any frames during the checkout process by adding zFORT® blue block.



3. Bridge:

It bridges the two lenses over your nose and holds most of the weight of your glasses. It’s a determining factor for how well the glasses will fit your face. For full-rim frames, the bridge forms part of the frame front. For half-rim or rimless frames, an extra piece is required. Bridges vary by style to suit different face shapes.



4. Temples:

They refer to the “arms” of your frames and are located on the sides of your head. Their core function is to keep your glasses secure as you go through the day wearing them. The length of the temple mentions the three dimensions of any frame, i.e., lens diameter, bridge width and temple length. Temples can be of the following types:


1. Paddle or blade or straight temple- It’s a temple without a bend to it and is therefore completely straight.

2. Curl sides- Also known as cable temples and typically found in wire or metal frames, the part of the temple close to the ear curls at the ends for a comfortable fit.

3. Drop or hockey end or swan neck- The most common design found in modern eyeglass frames. These frames bend downward to create a secure fit behind your ears. 



5. Hinges:

They are the metal joints that allow you to fold and unfold the temples of your glasses. They’re also called joints. There’s a variety of hinges available which are secured in different ways, such as spring hinges for example.



6. Screws:

These are what join two halves of a hinge together. These can be tightened to adjust the opening and closing mechanism of the temples. Any optician will be able to replace it for you if you lose a screw.



7. Nose pads:

These refer to the oval or circular pads that rest on your nose. These can be set up in either of these two ways:


1. Full rim nose pads- In this case, the nose pads are sculpted as part of the frame front. They’re polished so as to not be rough on your nose.

2. Push-in nose pads- This is a separate component attached to the end of the frame that rests on the nose. The bigger the pad, the more visible it is and the lesser it is likely to “dig” into the skin. 


You can also opt for adjustable nose pads for the best comfort.
