Scratches on glasses (eyeglass lenses) can be tricky—how easy they are to remove depends on **the lens material** (plastic, polycarbonate, or glass) and whether they have **coatings** like anti-reflective or scratch-resistant layers. Here’s a careful guide:
—
### **1. For Plastic Lenses**
Plastic lenses are most common and most prone to scratches.
#### **Methods**
1. **Toothpaste (non-gel, non-abrasive)**
* Apply a **small dab** on the scratch.
* Rub gently in **circular motions for 10–20 seconds**.
* Rinse with cold water and dry with a soft microfiber cloth.
⚠️ Avoid abrasive or whitening toothpastes—they can worsen scratches.
2. **Baking Soda Paste**
* Mix **baking soda + water** to make a thick paste.
* Rub gently in circular motions on the scratch.
* Rinse and dry.
3. **Commercial Scratch Removers**
* Products like **Novus Plastic Polish** are made specifically for lenses.
* Follow manufacturer instructions carefully.

### **2. For Polycarbonate Lenses**
* These are softer than plastic and often have **anti-scratch coatings**, so DIY methods can **damage the coating**.
* Best to use **lens-specific polishing products** or take them to a professional.
—
### **3. For Glass Lenses**
* Glass is much harder; **minor scratches may be polished** with cerium oxide paste.
* Deep scratches usually **cannot be removed**, and professional replacement is safer.
—
### **4. General Tips**
* Always use a **microfiber cloth**, never paper towels or clothing.
* Avoid harsh chemicals (bleach, window cleaner) on lenses.
* **Prevent scratches**: Use a hard case, avoid tossing glasses lens-down, and clean gently.
