Exposure duration: continuous for 4 h/day on 45 days
Animals were divided into the following four groups: i) control ii) treated with vitamin C (200 mg/kg body weight) iii) exposure to EMF iv) treated with vitamin C (200 mg/kg body weight ) + exposure to EMF

In exposed samples, the enzyme activities of superoxide dismutase, glutathione peroxidase and catalase were significantly decreased in comparison to the control group, while an administration of vitamin C increased these enzyme activities and brought them to normal levels with no significant differences compared to the control group. Additionally, in exposed rats, the concentration of malondialdehyde was significantly increased in comparison to the control. An administration of vitamin C prevented these effects.
The authors conclude that exposure to an electromagnetic field led to oxidative stress in the eye tissue and that vitamin C could prevent it.
