What’s the best material for eyeglass frames?

There are numerous materials from which eyeglass frames can be made, this has made it difficult to know which one would be more suited for you. This means you need to narrow down your options if you’re going to make the decision of the best material for eyewear. The factors to consider when choosing eyeglass frames include; weight, durability, colour, corrosion resistance, price, style, flexibility, and whether it’s hypo-allergenic. Begin by ranking these eight factors starting with the top three most important ones for you. When you’ve set the list of your priorities right you can choose the best for you from the following list:

Plastic eyeglass frames

In present times, the most common material from which eyeglass frames are made is plastic. This is because of its advantages which include being hypo-allergenic, inexpensive and lightweight. The designers of the eyewear also find plastic a great material because it can be made in a huge number of colours and can be moulded into any shape that’s desired. In the category of plastic eyewear material, there are three subcategories. We have Zyl, nylon blends and propionate. There are associated benefits of each of the three plastic materials. Zyl is low cost and offers the best texture and colour options. Propionate is the lightest in terms of weight and is the most hypo-allergenic. Finally, nylon blends have high resistance to temperature changes and are flexible. This makes nylon blends more suited for sports performances.

The major downside of plastic material is that it’s easier to break compared to metallic frames. If you leave them in your car and the temperatures in the car soar, the plastic eyewear is likely to warp. They can also burn easily, especially if you work around fires.

Metal eyeglass frames

The number of eyeglass frames made from metals is incredibly high. The main advantage that metal frames have over those made from plastic is that they’re stronger and can survive even with a lot of abuse. They’re resistant to corrosion and are also lightweight. The most common varieties of metal eyewear include:

Stainless Steel

These frames are lightweight, averagely priced and strong. As a result, most eyewear designs use it. The frame is also hypo-allergenic if it’s free from nickel. The finishes of this kind can either be polished or matte.

Titanium and Beta Titanium

Titanium is a very light metal which is also very cool. Such a frame can withstand so much abuse yet remain looking as good as new. Compared to other metals, it can be made into many more styles. Beta titanium, on the other hand, allows for more flexibility making it easier to resize or adjust. They’re also very durable.

Magnesium 

A frame made from magnesium is much lighter than other frames. However, it’s still strong, hypo-allergenic and durable. Compared to titanium, magnesium is lighter but more expensive.

Beryllium 

This material is lighter than aluminium and stronger than steel. They’re suited for skins with high acidity levels because it has better resistance to corrosion than other metals. They’re also great for people who spend time on salty beaches.

Memory Metal/Flexon

It’s an alloy of titanium that easily snaps back into shape, unlike other materials. It’s great for people who often expose their frames to a lot of abuse.

Aluminium

This metal allows for more unique designs than most other metals. It’s stronger than others but is similarly light. It allows for the making frames that are more creative, making it a favourite among high-end frame designers.

Precious metals like gold and silver can be used for making eyeglass frames but such metals don’t really have a benefit over the other materials. Silver isn’t comfortable, and gold is just too soft.
