The percentage of adult blindness is increasing at a very rapid rate, owing to the numerous accidents in factories and workshops, accidents that are, in many instances, preventable. Owners of factories, quarries, mines and other industrial plants have become alive to the necessity of safeguarding the eyes of their operatives, and much needed legislation is being enacted in all parts of the country. The National Council of Safety, an organization in existence but five years, has accomplished a great deal and this council co-operates with State Industrial Accident Commissions, and with civic and social organizations. The National Council of Safety estimates that there is one worker killed every 15 minutes, day and night, in the United States, and one injured every 15 seconds, day and night. This gives 30,000 killed and 2,000,000 injured, and of this number 200,000 are eye injuries. The National Committee for the Prevention of Blindness estimates that there are 100,000 blind in the United States, and half this number are needlessly so. Mr Will C. French of the State Industrial Accident Commission estimates that we have 1,000,000 employees in the state, and we have 300 industrial injuries daily, including Sundays. We thus have approximately 100,000 industrial accidents each year in this state. Since 1914, there were 23,451 eye injuries, and of these 549 were permanent injuries, and 11 resulted in total blindness. The medical and compensation costs of these eye injuries will be about $788,000. The 11 blind call for life pensions. The State Library home teachers are teaching 7 out of the 11 cases, and the Industrial Accident Commission is very glad to co-operate with us. In California we have an average of 26 eye injuries each working day, and this number is likely to increase, especially in the shipbuilding industry, because of the chipping steel, use of emery wheels, and machinery in the construction of vessels. The State Accident Commission advocates goggles, one pair to each man. There are four kinds of goggles used. Those for the protection against flying material, for protection against intense heat and light, for protection against gases, fumes and liquids, and dust goggles. Masks are urged for welders and babbiters, and these masks are so strongly constructed that they not only fit the eye, but have shields at the sides of each lens to prevent the flying chips from entering the eyes from the sides. In most of the large plants there are committees of safety composed of employees, and they do much to reduce industrial accidents. Precautionary leaflets are circulated among the workmen, and attractive posters, printed in all languages, are used. Some of these are very effective. One shows a man saying "good-bye" to his wife and five little ones, and underneath is written, "How could they do without you?" One of the best known slogans, and one carrying conviction, is "You can see through glass goggles, but you can't see through glass eyes."
