2. EVALUATION OF THE SAMPLES INSPECTED:
25X1A
A. INSPECTION OF A SINGLE SAMPLE OF SPECTACLE LENS PRODUCTION IS
INSUFFICIENT AS AN INDICATION OF THE QUALITY OF PERFCRMANCE BY ITS
MANUFACTURER. SINCE THESE LENSES WERE EXPORTED FOR SALE,HOWEVER,
IT IS BELIEVED SAFE TO ASSUME THAT THEY HAVE PASSED AN INSPECTION OF
SOME KIND AT THE POINTS OF THEIR ORIGIN AND THAT THEY ARE REASONABLY
REPRESENTATIVE OF COMPARABLE LENSES AVAILABLE FOR SALE TO CONSUMERS
IN THE COUNTRIES OF ORIGIN
B. THE INSPECTION REPORTED ABOVE HAS LED TO THE FOLLOWING JUDGMENT
OF THE QUALITY OF THE LENSES DESCRIBED:
(I) LENSES MARKED 7 AND II (BOTH DESIGNATED AS FROM
EASTERN GERMANY) GENERALLY MEET ACCEPTED AMERICAN FIRST
QUALITY STANDARDS. THESE LENSES DIFFER IN SIZE FROM LENSES
MARKETED IN THE USA,HOWEVER.
(2) THE LENS MARKED 10 (FROM CZECHOSLOVAKIA) IS REASONABLY
GOOD BUT INFERIOR TO THE FIRST TWO,AND TO AMERICAN LENSES OF
FdRST QUALITY.
(3) THE LENS MARKED 8 (FROM THE USSR) AND THE LENS MARKED 9
(FROM EASTERN GERMANY) ARE DECIDEDLY WORSE IN QUALITY THAN
NUMBERS 7,11, AND IO
(4) THE LENS MARKED 6 (FROM POLAND) IS POOREST OF ALL IN
QUALITY.
(5) THE LENSES EXAMINED EXHIBIT ROUGH EDGES AND POLISHING
STREAKS INDICATING THAT PRELIMINARY SURFACE GRINDING HAD BEEN
ACCOMPLISHED WITH A COARSER GRADE OF ABRASIVE.
C. THE LENS SIZE, THE TYPE USED IN PRINTING FOCUS AND THICKNESS,
AND THE DISTINGUISHING MARKINGS ON THE ENVELOPES OF THE GERMAN LENSES
(NUMBERS 7,9,AND II) MAY JUSTIFY THE CONCLUSION THAT THEY HAVE A
COMMON ORIGIN(ZEISS FACTORY IN EASTERN GERMANY).
