Eyeglass frames come in a variety of materials. The following is a
brief description of some of the materials available.
Titanium
This material has the advantage of being lightweight, durable,
strong and corrosion-resistant. Titanium comes in a variety of
colors. Sometimes manufacturers combine titanium with nickel or
copper. If you are allergic to nickel, you want to look for a frame that
is 100% titanium. Titanium frames tend to be a little more expensive due
to the manufacturing process.
Flexon
This material is patented by the manufacturer Marchon.
It is a titanium-base alloy with nickel. It is a unique material that
"remembers" its original shape if bent. It is lightweight and
non-corrosive. If you are a little hard on frames, this may be the
option for you.
Beryllium
This material is a lower cost alternative to titanium.
It resists corrosion and tarnish. It is an excellent choice for people
with high skin acidity or people who spend time around salt water. It is
lightweight, strong and flexible.
Stainless Steel
This material is a combination of stainless steel and
chromium. It is lightweight, has low toxicity and is nickel-free for
people who are allergic to nickel. It is one of the newer frame
materials that is not as familiar to people as titanium.
Zyl (plastic or cellulose acetate)
This material is making a comeback. It is very
cost-effective and comes in many styles and colors. It is a good
material for people that have metal allergies. One of the most popular
styles now is the multi-colored, layered frame. One drawback with
plastic material is that aging and exposure to sunlight can slightly decrease
its strength.
