The metal frames tend to be easier to adjust and are more flexible compared to plastic frames, not to mention that they are also lighter and slimmer.
When it comes to metal frames, titanium is considered as the lightest material. You can also find frames made of nickel alloy or stainless steel.
Flexible metal frames were also developed for the past few years. Even though metal frames have more limited color choices, the selection continues to grow day by day.
The common downside is that there are people who develop allergies to metal and this makes plastic spectacle frames a better option for them. As long as you are aware of the specific type of metal that you are allergic to, it will be easier for you to choose a frame made from another metal composition.
Don’t forget that you are never alone when it comes to choosing your specs. You can always ask the assistance of a registered optician to help you with your decision-making.
Strengths and Weaknesses of Plastic Frames
Unlike metal frames that you can buy at Crulle web shop, plastic frames have the tendency to be a bit thicker that may work well when it comes to hiding the edge of the lenses, especially if you happen to be very short-sighted. You can find plastic frames in an extensive variety of colors.

Plastic frames are also a safer option for sports. In particular polycarbonate frames are used in safety glasses due to their robustness.
Once again, consult your optician to get some assistance.
Strengths and Weaknesses of Rimless Frames
Many people find rimless frames attractive because these don’t hide the face and appear light as well. These frames are not as robust as those specs with metal or plastic frames. However, these are not ideal for those people who have active lifestyles or young children who might twist or grab the frames.
These frames often come with higher price tags and are not suitable for all prescriptions. In spite of this, a lot of people love and appreciate the appearance of rimless eyeglasses.
