MRTM: The lens material favoured by eyeglass makers

MRTM: The lens material favoured by eyeglass makers

MRTM by Mitsui Chemicals India has many distinct properties that make it the most sought-after lens material. It is made by a unique polymerization methodology that facilitates adding functions like control of specific wavelengths or photochromic properties by blending special dyes possible.

The following are some of the features that make it stand out:

1. High Refractive Index

  • MRTM brand of lenses is available in three distinct refractive indexes, namely, 1.60,1.6 and 1.74. Due to this feature, manufactuing of thinner and lighter lenses is easier.

2. Strength

  • MRTM lenses have high impact resistance and static load resistance, making them extremely safe for regular use. These lenses have cleared the US FDA’s drop ball test and the butterfly test for rimless frames.

3. Durability

  • They are resistant to weather conditions, heat, UV radiation, and abrasion. This way, the lens coating does not peel off and the surface also does not suffer chipping, even after long-term usage.

4. Abee Number

  • Abbe number indicates the degree of dispersion of light. As the Abbe number increases, there is less dispersion of light, resulting in reduced chromatic aberration. This improves viewing comfort.

5. Thin & Light

  • Generally, for higher optical powers, eyeglass makers use thicker glasses. But, since high-index lenses like MRTM can bend light more efficiently, they are thinner and extremely lighter. This way, they are highly comfortable for the user.

6. Strain Free

  • MRTM offers minimal stress-strain and thereby provides strain-free vision. This is because of the uniform polymerization of the glass mold of MRTM resin.

Applications of MR Series of lenses

1. It is used in the manufacture of single and progressive ophthalmic lenses. The processability of MRTM lenses enables them to be made into any design.

  • 2. MRTM lenses are used in tinted sunglasses as they have high stability features.
  • 3. They are extremely suitable for making polarized sunglasses.
  • 4. They are suitable for manufacturing sophisticated eyeglasses like rimless frames or high-curve lenses.
  • 5. MRTM lenses are used in making aspherical lenses where a high degree of precision is needed.

How do opticians choose high-index lenses?

Choosing lens materials is a crucial task, and opticians prefer sturdy, long-lasting lenses that also offer stellar clarity. To choose the best high-index lens material, they consider the following:


Mitsui Chemicals lenses properties

●      Abbe Number: Opticians opt for lenses with high Abbe number as they allow lower dispersion of light. This is suitable for making high-clarity lenses that are comfortable to wear.

●     Resistance to cracking: When exposed to pressure or shock, lens material should stay tough and must not crack. The lens material should be able to deform without chipping.

●     Resistance to abrasion: Scratch or abrasion resistance guarantees long life for lenses; therefore, it is another quality that opticians look for in lens materials.
