What causes nearlightedness?
Upon the assumption you meant "nearsightedness" here is the answer. Nearsightedness occurs when the physical length of the eye is greater than the optical length. This makes it more difficult for the eyes to focus light directly on the retina. If the light rays are not clearly focused on the retina, the images you see may be blurry.
When people are myopic are they long sighted or short sighted?
They're short-sighted. Yes, the term "Myopia" means short sightedness. This means that light entering the eye is focused in front of the retina rather than on it. The opposite term is "Hyperopia" which means long sightedness. This means the light entering the eye is focused behind the retina rather than on it.
