Para quienes usan lentes de contacto por primera vez, es esencial visitar a un optometrista u oftalmólogo calificado para un examen ocular completo y un ajuste de lentes. Al igual que las gafas, las lentes de contacto requieren una prescripción precisa. El uso de lentes con medidas incorrectas de dioptrías puede provocar fatiga visual, incomodidad y empeorar potencialmente las condiciones de visión existentes.


The la diferencia fundamental entre las gafas y las lentes de contacto radica en su posición en relación con el ojo. Las gafas se asientan aproximadamente a 12 mm de la córnea, mientras que las lentes de contacto descansan directamente sobre la superficie del ojo. Esta diferencia de distancia requiere la conversión de la prescripción utilizando la fórmula: poder de las lentes de contacto = poder de las gafas / (1 - 0,012 poder de las gafas). En esta fórmula, 0,012 representa la distancia en metros entre las lentes de las gafas y la córnea, y los valores de dioptrías son negativos para la miopía (miopía) y positivos para la hipermetropía (hipermetropía).


Generally, las reCEtas por debajo de 4,00 dioptrías (400 grados) requieren un ajuste mínimo, mientras que las recetas más fuertes necesitan una conversión significativa. Siempre consulte las tablas de conversión profesionales o consulte a su oftalmólogo para obtener mediciones precisas. Para esas con recetas diferentes en cada ojo, la identificación adecuada de las lentes en los casos de almacenamiento es crucial para evitar la incomodidad de intercambiar lentes.


Patients con El astigmatismo debe tener en cuenta que mientras que el astigmatismo menor (por debajo de 0,75 dioptrías) puede corregirse con lentes esféricas regulares, el astigmatismo superior requiere lentes de contacto tóricas especialmente diseñadas para una corrección óptima de la visión. Estas lentes cuentan con un posicionamiento estable del eje que mantiene la orientación correcta en el ojo, proporcionando una agudeza visual constante durante todo el uso.
