1. Compared with 1.60 index lenses at the same diameter and same power:
(1) Thinner - the average edge thickness is 11% thinner;
(2)Lighter - 7% lighter on average.
2. The ABBE Value is high up to 37, breaking through the difficulties of high index and low Abbe number, creating ultra-thin lenses with realistic imaging.
3. Compared with 1.60 index lens in lower price but thick, also 1.74 index lens thinner but high price, the 1.71 lens is both thin and cost-effective.
4. The tenacity of 1.71 lens is similar to the 1.67 MR-7 and is suitable for rimless/nylon frames.
5. Coatings: Like other lens materials, 1.71 index lenses can be paired with various coatings. These may include anti-reflective coatings to minimize glare, scratch-resistant coatings for increased durability, and UV protection to shield the eyes from harmful ultraviolet rays.
6. With the coating of the super hydrophobic, the lens gets more advantages of repel water effectively. When put ink in the surface of the lens, then shaking, the ink is concentrated and does not disperse, and there is no residual water stain.In addition to water repellency, SHMC coatings often offer other benefits such as oil and dirt resistance, scratch resistance, and easy cleaning. These properties can help to maintain the cleanliness and durability of the lens surface.
