What causes dipole-dipole interactions? The first thing required for there to be dipole-dipole interactions between molecules is for both molecules to have a dipole. These dipoles may be permanent (polar molecules) or temporary (instantaneous or induced dipoles in non-polar molecules). Polar molecules have an asymmetrical electron cloud/charge distribution.
Answers (2) 1  The abnormal growth direction of the eyelashe is generally called trichiasis. For children and teenagers, the cause of trichiasis is usually the abnormal growth of the epiblepharon and the epicanthus, or the congenital eyelid introversion. 2  That your eyelashes turn inward means you are suffering from trichiasis. If your eye lashes grow inward, you will feel uncomfortable because that the eye lashes are coarse. Trichiasis is usually caused by entropion, blepharitis, eye injury, distichiasis and idiopathic.
A bacterial infection can lead to a more serious condition like blepharitis, which is an inflammation at the base of your eyelashes that produces a thick, yellowish pus filled with bacteria-fighting white blood cells. People who are sick with cold or flu tend to have more eye discharge. Discharge is often associated with an eye condition called conjunctivitis. Conjunctivitis may be infectious (caused by a viral or bacterial infection), or sterile (caused by allergy, or some other irritant). When conjunctivitis is caused by an infection, it is commonly referred to as pinkeye.
