Some sunglasses are now designed specifically to block HEV.

Famous quotes containing the words visible and/or light:
“It is visible then that it was not any Heathen Religion or other Idolatrous Superstition, that first put Man upon crossing his Appetites and subduing his dearest Inclinations, but the skilful Management of wary Politicians; and the nearer we search into human Nature, the more we shall be convinced, that the Moral Virtues are the Political Offspring which Flattery begot upon Pride.”
—Bernard De Mandeville (1670–1733)
“And I live on, but in grief and self-contempt,
Left here without the light I loved so much,
In a great tempest and with shrouds unkempt.”
—Petrarch (1304–1374)
