¿Qué significa ser corto de vista?
Si usted no tiene dificultad para ver objetos cercanos, pero debe entrecerrar los ojos para enfocar objetos lejanos, es posible que sea corto de vista. Ser corto de vista es el término común que se utiliza para un problema de la visión denominado miopía.
La miopía es una condición que tiene lugar en el interior del ojo -el globo ocular es demasiado largo o la córnea (cristalino) es demasiado abrupta, lo que provoca que las imágenes converjan frente a la retina, el área que "procesa" las imágenes visuales. La gente que es corta de vista puede ver claramente los objetos que se encuentran "cerca", pero ve aquellos que están distantes con menor claridad o en forma borrosa.
La miopía es un problema común de la vista que puede intensificarse con la edad. Generalmente es bastante fácil de tratar con lentes correctivos o de contacto.
Nearsighted Symptoms:
Symptoms of nearsightedness are pretty easy to spot—eyes that feel tired or strained, headaches, squinting and blurred vision. The most obvious symptom is an ability to see objects that are “near” clearly, while having difficulty focusing on objects in the distance.
Nearsighted vision can develop at any time, but is most common in pre-teen children and adults over 40. Nearsightedness develops when the eyeball becomes “longer” than it should be, moving the “focal point” of the images we see from on top of the retina, to in front of the retina. Abnormalities in the eye’s lens or cornea can also cause nearsighted vision.
Nearsighted Diagnosis and Treatment:
Only an eyecare professional can accurately detect, diagnose and treat nearsightedness. That’s why routine comprehensive eyecare exams[/your-eyecare-visit/visiting-your-eyecare-professional.aspx] are so important to maintaining healthy vision and healthy sight.
Nearsighted vision is treated by helping your eyes to focus images correctly on the retina, rather than in front of it. This is done by prescribing eyeglasses, contact lenses or through a number of forms of surgery that help to reshape the surface of the eye.
Each treatment option has benefits and drawbacks that should be discussed completely with an eyecare professional.
