Difference between Sunglasses and Spectacles. Key Difference: Sunglasses are eye wear glasses that are used for the protection of the eyes from the bright light and harmful rays of sun, whereas goggles are close fitting eyeglasses that are equipped with side shields. Sunglasses or spectacles both tend to be valuable appliances.
In binoculars or goggles each eyepiece must be adjusted separately. To do this close your left eye and adjust the right eyepiece. Then open you left eye and adjust the left eyepiece to get a full contrast image. Some night vision goggles require objective focusing first, and then adjusting the eyepieces. Remember, that all night vision devices have a minimal focusing distance, a minimal distance at which objects can appear in full focus.
