Sunglasses, those stylish protectors from the sun's glare, are often subjected to accidental drops, bumps, and general wear and tear. A broken arm, a detached lens, or a cracked frame can leave you frustrated and without your favorite shades. Fortunately, many glues can effectively repair your sunglasses, bringing them back to their former glory. But choosing the right glue is crucial for a successful and long-lasting repair. This guide will explore the best glues for fixing various types of sunglasses damage, helping you choose the perfect adhesive for the job.
Understanding Different Types of Sunglasses Damage and Glue Selection
Before diving into specific glues, it's essential to understand the type of damage you're dealing with. This will greatly influence your glue choice:
1. Broken Arms/Frames:
For repairing broken arms or frames, you need a glue with high strength and flexibility. Rigid glues can crack under stress, leading to a re-break. Look for:
-
Cyanoacrylate (Super Glue): This is a popular choice for its fast-setting time and strong bond. However, use it sparingly and carefully, as it can be messy and difficult to clean up. Ensure the surfaces are clean and dry before application. Consider a gel super glue for easier application and less spillage.
-
Epoxy Resin: This two-part adhesive offers exceptional strength and durability, making it ideal for major frame repairs. It takes longer to cure than super glue, but the resulting bond is significantly stronger and more resistant to impact.
2. Detached Lenses:
Reattaching a detached lens requires a glue that creates a strong, transparent bond without affecting the lens's clarity.
-
UV-curing adhesive: These glues cure when exposed to ultraviolet (UV) light, providing a quick and strong bond. They are often used by opticians for lens repairs. The cured adhesive is usually invisible, maintaining the lens's clarity.
-
Optically Clear Epoxy: A specific type of epoxy designed for applications where transparency is crucial. It offers excellent strength and clarity, making it perfect for repairing detached lenses, particularly in high-quality sunglasses.
3. Cracked Frames or Lenses:
Repairing cracks presents a unique challenge. While glue can hold the pieces together, it may not restore the original structural integrity.
-
UV-Curing Adhesive (for small cracks): For minor cracks, a UV-curing adhesive can stabilize the crack and prevent further damage.
-
Epoxy Resin (for larger cracks): For larger cracks, epoxy resin may provide more robust support. However, it might not be aesthetically ideal, as it may be visible. Consider using a filler to smooth out the repaired area before applying the epoxy.
Best Glue Brands and Where to Find Them
While many brands offer effective glues, a few consistently stand out:

These brands are widely available at hardware stores, online retailers, and some pharmacies. Always read the product instructions carefully before use.
Tips for Successful Sunglasses Repair
-
Clean the surfaces: Thoroughly clean and dry the surfaces before applying any glue. Dirt or debris will weaken the bond.
-
Apply sparingly: Use only a small amount of glue to avoid excess spillage and ensure a strong bond.
-
Clamp or secure: After applying the glue, use clamps or tape to hold the pieces together while the adhesive cures.
-
Cure time: Allow sufficient curing time before handling the sunglasses. This ensures a strong and durable repair.
-
Consider professional repair: For expensive or intricate sunglasses, consider seeking professional repair to avoid further damage.
By carefully choosing the right glue and following these tips, you can successfully repair your sunglasses and extend their lifespan. Remember that the key is selecting an appropriate adhesive for the specific type of damage and following the manufacturer's instructions carefully.
