Abstract

L'invention concerne des lunettes flottantes pouvant être portées par les personnes atteintes de myopie et de presbytie pendant une longue période lorsqu'elles regardent des objets, et les lunettes sont des lentilles concaves légères simples pour la correction de presbytie dont la puissance réfringente Dloose est comprise entre Dmust et Dafter (Dafter incluse). Dloose représente la puissance réfringente des lunettes flottantes, Dmust représente la puissance réfringente nécessairement ajustée des lunettes, et Dafter représente la puissance réfringente des dernières lunettes dans la séquence de lunettes utilisée permettant fondamentalement de voir des objets clairement lorsque les yeux humains s'adaptent à l'état de repos. Le port pendant une longue durée des lunettes flottantes permettant à une personne atteinte de presbytie de voir des objets peut produire l'effet d'obtention d'une clarté visuelle accrue des objets regardés de près dans l'œil, et le port pendant une longue durée des lunettes flottantes permettant à une personne de voir des objets peut produire l'effet de réduction de fatigue oculaire.
