Single Vision 1.61 Aspheric MR-8 UV420 Blue Light Blocking HMC Hard Multi Coated Prescription Lenses

The Main Differences Between Mr-8 Lenses and Ordinary Lenses

Materials differ: MR-8 lenses are a polyurethane resin lens, while regular lenses may be made of glass, acrylic, or other resinous material.

Refractive index is different: The MR-8 lens has a refractive index of 1.60, which means that the MR-8 lens can be made thinner and lighter at the same degree. While ordinary lenses may have a low refractive index, resulting in relatively thick lenses .

Different Abbe number: The MR-8 lens has a higher Abbe number, up to 41-42, which means less dispersion and higher visual clarity. Ordinary lenses may have a lower abbe number, resulting in greater dispersion and poorer visual effect.

Durability is different: the wear resistance, impact resistance and yellow resistance of MR-8 lenses are better than ordinary lenses.

Different processing properties: The MR-8 lens has a high tensile strength, suitable for processing into rimless glasses or high arc glasses. Ordinary lenses may be more vulnerable to damage during processing.

Advantages of Single Vision 1.61 Aspheric MR-8 UV420 Blue Light Blocking HMC Hard Multi Coated Prescription Lenses

High definition ‌ : due to its Abbe number of more than 40, low degree of dispersion, so the imaging effect is very clear. ‌

High wear resistance ‌ : the hardness of the lens material is very high, the coating layer is very hard, and the wear resistance is very good, which can effectively resist scratches and wear in daily use ‌.

High impact resistance ‌ : good toughness, even if subjected to external force will only deform and not easily split. This is especially advantageous for rimless or half-rimmed glasses, ensuring the durability and safety of the lenses.
