Laser treatment involves using a focused laser beam to melt and smooth out the scratched surface. This method is more commonly used for repairing deep scratches on high-quality lenses, but it can be expensive and may not be suitable for all types of sunglasses.

Laser treatment is typically used for repairing high-end lenses, such as those found in prescription eyeglasses.

While laser treatment can effectively remove scratches, it may alter the lens’s coating and affect its optical properties.

Other Unconventional Methods

Various unconventional methods are touted online for repairing scratched sunglasses, including:

• Using toothpaste: Applying a small amount of toothpaste to the scratch and rubbing gently is said to smooth out the surface. However, this method can be abrasive and may damage the lens coating.
• Baking soda: Similar to toothpaste, baking soda is a mild abrasive that can be used to polish out scratches. However, it can be harsh on the lens and should be used with caution.
• Polishing with a soft cloth: Rubbing the scratched area with a soft cloth, such as a microfiber cloth, can sometimes reduce the visibility of scratches. However, this method is not effective for deep scratches.

These methods are often based on anecdotal evidence and should be approached with caution. They may not be effective for all types of scratches and could potentially damage the lens.
