Semi-finished 1.61 UC/HC/HMC Single Vision Lens

1. Thinner and Lighter
● Higher Index of Refraction: With a refractive index of 1.61, these lenses are thinner and lighter than standard plastic lenses (which typically have an index of 1.50 and 1.56 ). This is especially beneficial for people with stronger prescriptions, as it reduces the “coke-bottle” effect of thick lenses.

2. Higher Durability and Scratch Resistance
● Many 1.61 lenses are made from high-quality materials that are more resistant to scratching than traditional plastic lenses. This makes them more durable and long-lasting, reducing the likelihood of needing replacements due to damage.

3. Better Visual Clarity
● Lenses with a higher refractive index, like the 1.61, often offer clearer vision due to the reduced thickness. This is because thinner lenses tend to be more optically accurate, improving the overall clarity of vision, especially for high prescriptions.

4. UV Protection
● Many 1.61 lenses come with built-in UV protection, which helps to shield your eyes from harmful ultraviolet rays, providing an added layer of protection against eye strain and long-term damage.

5. More Lightweight for Comfort
● Lighter lenses reduce the overall weight of the glasses, making them more comfortable to wear for extended periods. This is particularly advantageous for people who wear glasses all day.

6. Versatility in Frame Design
● Because the lenses are thinner and lighter, they can be paired with a wider range of frame styles, including metal, plastic, or rimless designs. This allows for more flexibility in choosing frames without worrying about the weight or thickness of the lenses.

7. Reduced Edge Thickness
● In stronger prescriptions, the edge of the lens can become very thick and noticeable. The 1.61 index reduces this effect, creating a more uniform and attractive lens profile.
