Abstract

A preliminary survey at Jalan Rahmadsyah Medan showed that welding workers at the company suffer visual acuity disorders with symptoms such as eyes smarting, irritation, light sensitivity, and blurring. These are caused by exposure to ultraviolet radiation from welding activities. The goal of this research was to analyze the i"rifl,uence of ultraviolet radiation, the characteristics of worker and eye protector equipment (welding goggles) on visual acuity. The following research used a cross sectional, with observation on one of the welding industries in Medan with a total population of 32 welding workers and the total sample of 32 welding workers. The statistical test were used Multiple Linear Regression. From 6 of independent variables observed founded 5 variables statistically significant with p < 0.05, namely variable of ultraviolet radiation p = 0.042, education p = 0. 000, exposure duration p = 0. 000, knowledge p = 0. 008 and eye protector equipment (welding goggles) p = 0. 000. Based on Multiple Linear Regression was known that exposure duration variable had more dominant influence on visual acuity. It is suggested to the owner of welding industries to control workers and to provision suitable welding goggles, and for the workers suggested always use the personal safety when they are working.
