What are the Different Types of Hinges for Glasses?
Glasses are not just about frames and lenses; hinges also play a crucial role. These small components
allow the arms of the glasses to fold and unfold, while influencing the comfort and durability of your glasses.
There are three main types of hinges for glasses: standard hinges (or barrel hinges), spring hinges (or flexible),
and screwless models. Each type has its own characteristics that are better suited to style preferences, daily activities,
and budget.
Standard or Barrel Hinges
Standard hinges, also known as barrel hinges, are the most common in the world of glasses. Their design
relies on a series of small metal cylinders (called "barrels") that interlock like a zipper, held together by a screw.
These barrels can be adjusted precisely to provide optimal comfort.
Advantages of Barrel Hinges:
- •Easy to repair : The simplicity of these hinges makes them easy to repair with a glasses repair
kit, often following a simple tutorial.
- •Durability : Due to their simple and proven design, these hinges are sturdy and resistant.
- •Affordability : Glasses with barrel hinges are often more affordable due to their simple
construction.
Disadvantages of Barrel Hinges:
- •Adjustment sometimes necessary : For precise adjustment, a visit to the optician may be required.
- •Less suitable for sports activities : The arms attached to the standard hinges may lack
flexibility, making them less suitable for activities that require intensive movement.
Among the barrel hinge models, there are configurations of three, five, or seven barrels. While seven-barrel
hinges are stronger, they may be more difficult to adjust and repair.
Spring or Flexible Hinges
Spring hinges are especially appreciated for their flexibility. Unlike standard hinges, they incorporate a
spring that allows the arms to open beyond 90 degrees, ensuring a secure fit without compressing the temples.
Advantages of Spring Hinges:
- •Constant fit : Once adjusted, they maintain their initial balance without requiring frequent readjustments.
- •Suitable for active lifestyles : Flexible hinges allow the arms to better adapt to the
shape of the head, perfect for sports activities or very active days.
- •Extended comfort : The spring prevents the feeling of pinching on the sides of the head,
even after many hours of wear.
Disadvantages of Spring Hinges :
- •More complex repairs : In case of damage, it is often necessary to consult an optician
to repair them, and for glasses using proprietary technologies, a return to the manufacturer may be required.
Several brands use proprietary technologies to optimize spring hinges, such as Persol with its Meflecto system,
which allows the arms to bend without compressing. Aspex Eyewear's EasyTwist TurboFlex glasses, with 360-degree flexible
hinges, or Sferoflex's patented hinges, which adapt to the contours of the face, are also examples of innovative solutions.
Screwless Glasses
Screwless glasses represent a recent innovation in the optical field. Unlike traditional glasses, they have no hinges
and rely on curved arms to stay in place. Often made of titanium or other flexible and durable materials,
these glasses are ideal for sports enthusiasts and those with an active lifestyle.
Advantages of Screwless Glasses:
Screwless glasses are particularly popular with sports brands, such as Maui Jim, which offer models suited
for those looking for durable and flexible frames.
Can I Replace Broken Hinges?
The short answer is yes! Depending on the extent of the damage, it is possible to replace barrel and spring hinges,
although repairing glasses hinges can sometimes be complicated. Spring hinges, especially those that include
proprietary technologies, may require a visit to the optician or a return to the manufacturer for replacement.
