             BMC REPORTS RECORD SECOND QUARTER EARNINGS

July 22, 1997 -- Minneapolis, MN -- BMC Industries, Inc. today reported record
second quarter net earnings of $11,989,000 or $0.42 per share, up 22% from
earnings of $9,842,000 or $0.35 per share in the year-earlier period.  Second
quarter revenues increased 18% from $68.2 million in the second quarter of 1996
to $80.3 million in the second quarter of 1997.

Net earnings for the first six months of 1997 totaled $19,872,000 or $0.70 per
share.  This represented an improvement of $3,847,000 or 24% over the
$16,025,000 or $0.57 per share recorded for the first six months of the prior
year.  Revenues for the first six months of 1997 were 15% higher than the same
period in the prior year. 

The second quarter of 1997 represented another quarterly earnings record for BMC
and its twenty-fifth consecutive quarter of increased net earnings over the
year-earlier period, excluding income from the sale of equipment and technology
and other non-recurring items.  Once again, each division contributed to this
significant accomplishment.

The Company's Precision Imaged Products operation (PIP includes both the Mask
Operations and Buckbee-Mears St. Paul) posted record second quarter results. 
Second quarter sales and profits increased 25% over the prior year quarter.  The
profitability of Mask Operations increased primarily due to the continued sales
mix shift to higher margin products, including high resolution computer monitor
masks.  Sales of large (25 - 29 inches) and invar television aperture masks
increased 35% and 31%, respectively, over second quarter 1996 sales.  Jumbo mask
sales slightly lagged 1996, which was a difficult comparison following a 42%
increase over the second quarter of 1995.  The further weakening of the German
mark relative to the U.S. dollar had virtually no impact on earnings but reduced
sales, as compared with the prior year quarter, by nearly $1 million.  Finally,
second quarter etching sales of Buckbee-Mears St. Paul increased 27% over the
prior year, due to strong growth in the electronics, medical, filtration and
automotive markets.

   Second quarter Precision Imaged Products sales included over $2 million of
high resolution computer monitor mask sales.  High resolution mask sales were
depressed by a number of factors including:  line time required for new customer
and part qualification, a continued market surplus

of 14-inch monitor tubes due to an inventory build at the end of 1996 and the 
devotion of over two weeks of line time to invar television mask production 
due to a customer emergency.  The line is performing at expectations and we 
expect sales to grow significantly over the balance of the year as we receive 
new customer and part approvals.

The new television line in Cortland started-up in the second quarter and 
performance exceeded expectations.  Initial shipments from this new line 
occurred during the second quarter.  The new monitor line in Cortland is 
scheduled for third quarter start-up, with de-bugging of the line currently 
taking place.

BMC's Optical Products operation also produced record second quarter results. 
Second quarter sales increased 4% over the prior year quarter, while 
profitability increased 5%.  Sales growth occurred in each major product 
line, except for glass.  Sales of high end products (polycarbonate, 
progressive, high index and polarizing sun lenses) showed strong growth, 
increasing 15% over the year-earlier period.  Profitability was impacted by a 
number of one-time expenses including:  expenses preparatory to the shutdown 
of the Ft. Lauderdale plastic lens manufacturing facility which ceased 
operations in July, expenses incidental to the new polycarbonate 
manufacturing, centralized distribution and research and development facility 
and start-up costs for the operation's first anti-reflective coating machine. 
In addition, resources devoted to the ongoing development of new products 
and materials were higher in the second quarter. Construction of the new 
facility remains on schedule for completion in the third quarter of 1997.

BMC is one of the world's largest manufacturers of aperture masks for color 
television tubes and computer monitors.  The Company is also a leading 
supplier of polycarbonate, glass and plastic eyewear lenses.  The common 
stock of the Company is traded on the New York Stock Exchange under the 
symbol "BMC".
