What is short-sightedness? What is myopia?

Short-sightedness is an English term for myopia. It is a minus refractive defect. Short-sightedness is corrected with diverging lenses - diopter glasses with a minus (-) mark. The eyeball is too long in the case of short-sightedness. Long-distance refracted rays meet in front of the retina. A short-sighted person cannot see well in the distance. A certain advantage is that they can see up close without glasses. Short-sightedness of up to cca -10 diopters can be corrected with laser surgery. ICL-type surgery is a better solution for more serious disorders. RLE and PRELEX-type surgery is sometimes a better solution for people over 50 years of age.
