QUESTIONS & ANSWERS
	QUESTIONS	ANSWERS
	WHAT IS THE DIFFERENCE BETWEEN A POLARIZED LENS AND AN ORDINARY TINTED LENS?	WHILE ORDINARY TINTED LENSES REDUCE BRIGHTNESS, ONLY POLARIZED LENSES ELIMINATE GLARE. POLARIZATION IS ACHIEVED BY PLACING A THIN SHEET OF POLARIZED FILM BETWEEN TWO LAYERS OF MATERIAL.
	HOW DOES A POLARIZED LENS WORK?	LIGHT RAYS VIBRATE IN MANY DIRECTIONS. AS LIGHT PASSES THROUGH A POLARIZED LENS, THE POLARIZED FILM CHANNELS THE LIGHT RAYS TO TRAVEL IN THE SAME DIRECTION; THUS ELIMINATING UNSIGHTLY GLARE, MUCH THE SAME WAY AS A VENETIAN BLIND CHANNELS LIGHT.
	IS IT POSSIBLE TO GET A CLEAR POLARIZED LENS?	NO, IT IS NOT. THE AMOUNT OF POLARIZATION A LENS ACHIEVES IS PROPORTIONAL TO THE DENSITY OF THE FILM. THE LIGHTER THE FILM, THE LESS POLARIZATION A LENS CAN OFFER. TINTING A LIGHT POLARIZED LENS DOES NOT INCREASE ITS POLARITY. IT SIMPLY DARKENS THE LENS AND REDUCES BRIGHTNESS. TO ACHIEVE MAXIMUM POLARIZATION, YOU MUST USE A LENS THAT UTILIZES A DARK (GREY-C OR BROWN-C) FILM.
	HOW THIN CAN THESE POLARIZED LENSES BE SURFACED?	THE FOLLOWING ARE OUR RECOMMENDED CENTER THICKNESS': (A) NORMAL CR-39TM POLARIZED LENSES - 1.8MM (B) HI INDEX POLARIZED LENSES - 1.7MM (C) POLARIZED POLYCARBONATE LENSES - 1.5MM (D) GLASS POLARIZED LENSES - 3.0MM TO 3.5MM. OUR GLASS LENSES REQUIRE ADDITIONAL CENTER THICKNESS TO ACCOMMODATE THE FRONT WAFER AND SEGMENT THICKNESS.
	ARE POLARIZED LENSES AVAILABLE IN FINISHED FORM?	YES, BUT ONLY IN PLANO. ALL POLARIZED PRESCRIPTION LENSES MUST BE SURFACED SO THAT THEY CAN BE MOUNTED WITH THEIR AXIS AT 180º.
	WHAT DETERMINES A SUPERIOR QUALITY POLARIZED LENS?	THE THREE MOST IMPORTANT FACTORS IN GRADING A POLARIZED LENS ARE: (A) CLARITY OF THE POLARIZED FILM: INFERIOR POLARIZED LENSES HAVE A HAZY FILM. (B) DENSITY OF THE POLARIZED FILM: LENSES THAT POSSESS A LIGHT FILM WILL NOT PERFORM AS WELL AS LENSES THAT UTILIZE A DARK FILM. (C) FILM PLACEMENT: IN ORDER TO ACHIEVE A COSMETICALLY APPEALING THIN PAIR OF EYEGLASSES, THE LABORATORY MUST BE ABLE TO KNOW, WITH CERTAINTY, EXACTLY WHERE THE POLARIZED FILM IS PLACED IN RELATIONSHIP TO THE FRONT OF THE LENS.
	WHAT IS THE MOST EFFECTIVE WAY TO DEMONSTRATE POLARIZATION?	DEMONSTRATING WITH A POLARIZED LORGNETTE. HAVE THE CONSUMER LOCATE AN OBJECT THAT IS REFLECTING GLARE AND THEN VIEW THE GLARE THROUGH THE POLARIZED LORGNETTE. THE GLARE WILL SIMPLY DISAPPEAR - A HANDS ON EXPERIMENT OF SHOW AND TELL.
	DO GLASS POLARIZED LENSES REQUIRE CHEM TEMPERING OR HEAT TREATING?	GLASS POLARIZED LENSES ARE EXEMPT FROM THE F.D.A.'S DROP BALL TEST REGULATIONS. THIS IS BECAUSE, LIKE THE WINDSHIELDS OF OUR AUTOMOBILES, GLASS POLARIZED LENSES ARE LAMINATED.
	CAN POLARIZED LENSES BE TINTED AND IS TINTING RECOMMENDED?	YES, PLASTIC POLARIZED LENSES MAY BE TINTED. WE RECOMMEND A TINTING TEMPERATURE OF 200 DEGREES OR LESS. WE RECOMMEND TINTING FOR THOSE PEOPLE TRYING TO ACHIEVE A PARTICULAR COLOR BUT IT SHOULD BE REMEMBERED THAT YOU DO NOT INCREASE POLARIZATION BY TINTING.
	DO POLARIZED LENSES PROVIDE U.V. PROTECTION?	ALL OF OUR POLARIZED LENSES AFFORD 99% ABSORPTION AT 380 NANOMETERS.
	CAN POLARIZED LENSES BE AR COATED?	YES, HOWEVER, IT IS UNNECESSARY TO AR COAT BOTH SIDES. WE NORMALLY RECOMMEND COATING ONLY THE BACK SIDE CURVE.
