1. A light treatment apparatus comprising:
- a casing;
a light source disposed in said casing for generating a predetermined number of light pulses of a predetermined duration, light intensity, and total energy;
an applicator element mounted to said casing in optical communication with said light source for directing light from said source to a target;
at least one signal generator for generating and transmitting, to a sensor, at least one trigger signal prior to the generating of said light pulses by said light source; and
a control unit operatively connected to said light source and said signal generator for synchronizing the operation thereof.

Abstract
A light treatment apparatus includes a light source and a preliminary light generator. The light source is disposed in a casing for generating a predetermined number of primary light pulses of a predetermined first duration, first light intensity, and total energy. The preliminary light generator is mounted to the casing for generating at least one preliminary light pulse having a sufficient intensity to activate a light limiting reaction in protective eyewear of a user prior to the generating of the primary light pulses.

19. A light treatment method comprising:
-
generating a predetermined number of light pulses of a predetermined duration, light intensity, and total energy;
directing said light pulses to a target;
automatically generating at least one trigger signal prior to the generating of said primary light pulses;
transmitting said trigger signal to a sensor prior to the generating of said primary light pulses; and
in response to a receipt of said trigger signal by said sensor, automatically generating a light limiting reaction in a generally transparent light-limiting optical material, thereby preventing transmission of said light pulses through said generally transparent material. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A method for protecting eyes from being damaged by pulsed light, comprising:
-
providing a window of a generally transparent light-limiting optical material;
disposing said window in front of a set of eyes; and
in response to a high intensity light pulse directed at said window from a side opposite said eyes, automatically generating a light limiting reaction in said generally transparent light-limiting optical material, thereby preventing transmission of said light pulse through said generally transparent material.
