When to Replace Your Glasses: Key Signs to Watch For
The lifespan of glasses depends on how often they are used, how well they are maintained, and the materials involved. Typically, glasses last around 2 years with regular use. Here’s a simplified guide to help you know when it’s time to replace your lenses and frames.
1. Lens Issues
Lenses are made of resin and require protective coatings for functionality. These coatings, however, wear out over time, leading to several common problems:
- Coating Cracks: Exposure to heat or wear can cause the coatings to crack, impairing vision and potentially worsening your prescription.
- Scratches: Scratches, especially in the optical center, can directly affect clarity.
- Yellowing and Color Deposits: Lenses may yellow or accumulate color over time due to environmental exposure.
Replace lenses if:
- Coatings are peeling or cracked.
- Scratches in the center are affecting vision.
Yellowing or deposits appear after 2 years.
2. Frame Issues
The frame material impacts durability:
- Metal Frames: These are prone to deformation. Once bent, they often can't be fixed. They may also lose color after a year, especially around areas that contact skin, and parts can break or loosen over time.
- Plastic Frames: They can warp in heat or become brittle in cold temperatures. Lower-quality plastics like TR90 may discolor over time, affecting appearance.
Replace frames if:
- The frame is severely deformed and can’t be reshaped.
- Parts like nose pads break off.
- Significant color fading or cracks appear.
By keeping an eye out for these issues, you can ensure you always have clear vision and comfortable wear. If you experience any of these signs, it’s time to replace your glasses.
