Resumen
Box for the measurement of the amplitude of accommodation with ophthalmic lenses. A new equipment is presented that allows the measurement of the amplitude of accommodation, by the method of the use of ophthalmic lenses for the compensation of ametropia. It consists of a box of a lightweight material that includes a set of sheets with ophthalmic lenses, a sheet with optotypes of different sizes that subtend the same angle with any combination of negative lenses interposed. The device eliminates the subjective errors of the test committed by the optometrist in the evaluation of the accommodation. It is also possible to reduce the size of the optotype by increasing the power of ophthalmic lenses. (Machine-translation by Google Translate, not legally binding)
