Abstract
El objeto de la presente invención son lentes de refracción aún mayor que le permitan al óptico fabricar lentes para gafas para altos valores de dioptrías con grosores de borde aún más reducidos (para lente de menos) y/o grosores centrales aún más reducidos (para lente de más). Los radios planos aumentan el campo visual óptimamente eficaz y mejoran el efecto cosmético. El peso específico se deberá mantener para las lentes de mayor refracción lo más bajo posible si las lentes le han de aportar ventajas a los portadores de gafas.
