| Abstract
Introduction: Considering the fact that man's eye pupils change their diameters against light variation, coincidental disorders occur in the eye sight. This becomes more important when she/he is doing a sensitive work such as driving at night. Among the factors which may cause night driving accidents is high light of the opposite cars which create dazzling and change in the pupil diameter rapidly that finally causes drivers to become blind for a moment.
Materials & methods: Designing this apparatus has been fully inventive and recorded in the state inventions record administration with No: 32651 . This apparatus parts are: a part connected to the driver's cab, an engine–house, an engine to raise the frame holding a half–transparent plate, a fixing frame, an engine to raise the lever which locks the frame, a key to activate the raised–engine of the fixing frame, power, stop-start key of the system.
Findings: The universal purpose of the apparatus designation is to reduce light intensity reflected to the drivers' eyes while the opposite coming trucks use their up head-lights. This dazzling light is frustrated through an absorption and dispersion process by the device. Whenever using the system, no intense light reflects to the drivers' eyes because the opposite light intensity reduces after passing the semi-transparent plate.
Conclusion: The constructed apparatus was tested and justified following necessary studies. Applying this apparatus can be effective, in reducing the disturbing coming up-lights and facilitating the drivers' ease at night. Unfortunately, lack of necessary technology in the province hindered constructing this device in accordance with appropriate principles. |
