Purpose: Recently, bacterial contamination of equipment and accessories required for vision correction has become a main causal factor in ophthalmic diseases. Thus, We investigated on both the actual condition of bacterial contamination from glasses of vision correction. Methods: Investigation of microorganisms was carried out with a group of 145 glasses wearers, composed of 36 elementary school students, 37 middle school students, 38 high school students, 10 college students, and 32 aged men. Results: Seventeen species of bacteria are detected from glasses of vision correction: B. cereus, B. licheniformis, Bacillus sp., CNS, Enterococcus sp., Escherichia coli, Proteus sp., Pseudomonas sp., Serretia sp., Streptococcus sp., Staphylococcus epidermidis, Staphylococcus aureus, Streptococcus hemolyticus,, Acinetobacter sp., Enterobacter cloacae, GNR, and Pseudomonas aeruginosa. Among 17 species of bacteria, there are some potential causative agents for keratitis, corneal ulcer, Acute dacryocystitis, Orbital cellulitis, Periphlebitis retinae, Marginal blepharitis, and Acute conjunctivitis. Enterobacter cloacae, Pseudomonas aeruginosa and Staphylococcus epidermidis cause keratitis. Pseudomonas sp., and Staphylococcus aureus cause corneal ulcer. Staphylococcus aureus causes acute dacryocystitis, orbital cellulitis, periphlebitis retinae, marginal belpharitis. Streptococcus hemolyticus causes acute conjunctivitis. Conclusions: In summation, it is verified that hazardous, opportunistic and infectious microorganisms exist in glasses for vision correction. Ophthalmic diseases are predicted. Therefore, supplementary research on the development of a cleaning solution to cleanse the infection and of an effective method to remove microorganisms is required.
