Thin lenses for strong prescriptions

I want thin eyeglasses lenses for my eyes with excessive myopia.

I want to say goodbye to coke-bottle-thick eyeglass lenses! We offer comfortable visual living with ultra-high-index lenses.

Impact of severe myopia and hyperopia on eyeglass lenses

When lenses are thick and heavy, they put strain on the face, and the user is likely to feel fatigue by long-time use.
Lenses for myopia have a thick edge, and lenses for hyperopia are convex at the center. Thus, these lenses look unsightly.
Through lenses with a strong power, the contour of the face of the user looks concave or swelling, and this is also undesirable.

Relationship between index and thickness

The higher the index of a material, the stronger the force of bending light. Based on this principle, the thickness of lenses can be reduced even if the power is the same.

Countermeasures / Improvements

Tokai Optical’s “1.76 Material,” which is the plastic lens material with the highest index in the world, can reduce the weight and thickness of lenses.
Double-surface aspherical lenses are thinner and offer improved visibility.
By selecting a smaller eyeglass frame, the effect of reducing the thickness of the lens and the gap of the contour of the face of the user can also be expected.
Double-surface aspherical lenses are thinner and offer improved visibility. In addition, materials with indexes of 1.8 and 1.9 are also available for glass lenses.
The total weight of eyeglass lenses can be further reduced by combining a lens material or design and processing services.
