Refractive errors are caused by a decoupling of the power of convergence of the eye lens, the cornea and lens, which make the rays reaching the eye to focus and generate an image, and the retina, which is the biological photosensitive screen where the image will be transformed into a nerve impulse. These defects include myopia, hyperopia and astigmatism. Presbyopia can also be considered a refractive defect, but of special features, since only affects near vision in patients older than 40 years. By altering the quality of the focused image on the most sensitive area of the retina (the macula), they decrease visual acuity. For their management several options exist, from the use of glasses and contact lenses to surgical correction (refractive surgery). The incidence of certain refractive errors (myopia specifically) has increased in recent decades, some environmental factors related to it have been identified. Some medical management measures have shown a positive effect in controlling its onset and progression.

Danish Ophthalmology - from start to 1865.

This short paper mentioned the medical treatment using the 'holy' springs, the first 'eye doctor' in Denmark, the first picture of spectacles which was found in Viborg Cathedral of the high priest before he performs circumcisio praeputii on Jesus Christ, further cataract reclination in Denmark from around year zero and cataract extraction in 1667 in Denmark on a goose by Francisco Borri and on humans by the Danish Georg Heuermann in 1755. Epidemic military eye diseases in 1807, 1856 and 1865 are also described in this study. From 1856, a new ophthalmological period started in Denmark with the first eye hospital (lazaret only for eye diseases), and in 1864, patients with eye diseases were transported from the few beds in the surgical departments in the municipal hospital to the first civil eye department in Denmark, the eye hospital Sct. Annae in Copenhagen. The new scientific period started with Jacob Christian Bentz (ophthalmia granulosa, joint editor of the Danish Medical Journal) and Heinrich Lehmann.
