Myopia, or nearsightedness, is characterized by the difficulty of seeing clearly an object in the far distance.
It is an extremely common refractive error—in fact, in many developed countries, about half of the population needs correction for myopia.
If you are short-sighted, you may have difficulty reading road signs, watching TV or seeing things from afar. Bad distance vision can also result in feeling fatigued when driving or playing sports.
Shortsightedness is caused by the eyeball being too long in comparison to the refractive power of the crystalline lens. This causes the focusing to take place in front of the retina, which results in the retinal image being blurred, much like a photo taken by an unfocused camera lens.
The simple solution to rectify shortsightedness is to wear a corrective lens that will focus the light back onto the retina. Lenses that correct myopia are sometimes called “negative lenses” because they send the light focus backwards.
In Japan and in many other countries, a large part of the population suffers from myopia, and Nikon has developed unique optical technologies to give them back the best vision at far distances.
