Glass magnifiers have some advantages over Optical Grade Acrylic lenses the main one being exceptional scratch resistance and ease of cleaning. Glass magnifiers  having high scratch resistance, makes them ideal for various applications, especially in demanding environments where abrasive media or material or acids are used.

• Scratch Resistant and Easy to Clean: Glass magnifiers are highly scratch resistant, ensuring long-lasting clarity and performance. Additionally, their smooth hard surface makes them easy to clean, maintaining their optical integrity and enhancing their longevity even in the most demanding industrial environments.
• Resilient Around Acids and Tools:  Glass magnifiers excel in environments involving acids, grinding, abrasive substrates, and tooling. Their resistance to chemical corrosion and mechanical wear, and repeated cleaning, makes them reliable companions for tasks that might degrade other types of magnifiers.
• Optically Glass Lenses Are Generally Not as Good as Optical Grade Acrylic Lenses: While glass lenses possess scratch resistance and durability, high-grade acrylic lenses are often favored for their superior optical properties, such as clarity, brightness and wider field of view. Acrylic lenses are generally more optically superior & provide exceptional clarity and reduced distortion, making them ideal for applications where optical precision is paramount.
• Inverse Relationship Between Lens Size and Power:  It's important to understand the inverse relationship between lens size and magnification power when choosing your magnifier. As magnification increases, lens size generally decreases. This physics principle guides the design and function of magnifiers to achieve specific levels of magnification and clarity.
