For example, H-Cl has a dipole. The electrons spend more of their time near the Cl atom (the red end in the diagram below). A dipole-dipole interaction is the attraction between two polar molecules. When they approach each other, the negative end one molecule attracts the positive end of the other.
Eyes sensitive to light can also be caused by viruses or inflammation, such as those found in sinus infections. If you have a cough, aching jaw, blocked nose, headaches and lethargy then it's best to visit your GP for a diagnosis of a possible sinus infection and simple antibiotic treatment.
Find an Ophthalmologist. Light sensitivity causes a person to shield their eyes from light, often to prevent eye pain. The symptoms and possible related eye conditions/diseases in this section are for general reference only, and do not contain all visual symptoms or all possible related conditions or diseases. If you have any unusual vision symptoms, speak with your ophthalmologist.
