Are foldable glasses good?

The pros and cons are as follows:
 
Advantages
 
- Portability: They can be folded into a small size, making them easy to carry in pockets, small bags or travel cases, which is very convenient for people who are often on the go.
- Space-saving: They take up less space when stored, which is beneficial for those with limited storage space, such as in a crowded drawer or a small vanity.
- Diverse styles: There are various styles of foldable glasses available in the market, including both fashionable and practical designs, allowing wearers to choose according to their personal preferences and needs.
- Functionality: Besides regular corrective glasses, there are also foldable sunglasses and safety glasses that offer the same optical and protective functions as non-foldable ones.
 
Disadvantages
 
- Durability: The folding mechanism may be a weak point. Frequent folding and unfolding may cause wear and tear on the hinges and joints, potentially leading to breakage over time.
- Optical stability: In some lower-quality foldable glasses, the lenses may not be as stable as those in traditional glasses. There is a possibility that the folding process could affect the optical alignment, which may slightly impact vision correction or visual clarity.
- Comfort: Some foldable glasses may have less comfortable frames, as the need to fold might limit the materials and designs that can be used to ensure a good fit and comfort on the face.

 
If you value portability and convenience highly and don't mind the potential trade-offs in durability and comfort, foldable glasses can be a good choice. However, if you prioritize long-term use, high optical quality and maximum comfort, traditional non-foldable glasses might be more suitable.
