In futuro l’umanità avrà bisogno di più occhiali e lenti a contatto. Lo dice uno studio scientifico pubblicato sulla rivista Opthalmology. Un team di specialisti australiani afferma che entro il 2050 circa 4,8 miliardi di persone soffriranno di problemi alla vista, vale a dire il 49,8% della popolazione mondiale. Un vero e proprio incremento se confrontato con i dati del 2010, dove la percentuale si fermava al 28,3.
In Europa occidentale il fenomeno sarà più evidente, rispetto ad altre parti del mondo. I motivi alla base di questa tendenza? Le nuove abitudini sviluppate dagli esseri umani. Da una parte la scarsa esposizione alla luce diretta del sole, dall’altra l’abitudine a leggere sempre più da vicino da tablet e computer.
