ABSTRACT
Background : There are approximately 15,000 workers in several spurious eyelash industries in Purbalingga Regency. Since objects being observed are very fine and the tasks need high accuracy, good lighting is therefore highly required. Poor lighting can lead to visual and mental fatigue, stiffness around the eyes, eye damage and the increasing of work accidents. Sufficient intensity and good management of lighting will result a comfort environment in accordance to achieve a safe work environment.
Method : This research was conducted as observational study with a cross sectional approach for 45 samples of workers. Sampling was carried out by using of systematic random sampling. Data of light intensity and reflectance were collected by measurement of light using Lux Meter and assessment of visual fatigue by using Retention Timer. Other data were collected by interviewing workers with age limitation up to 33 years old.
