如果近视度数在300°以下，隐形眼镜的度数和框架镜的度数是一样的。如果

If the degree of myopia is below 300°, the degree of contact lens and the degree of frame lens are the same. If the power is between 300-500°, then the power of the contact lens is 25° smaller than the power of the frame lens. If the degree of the patient is> 500°, the degree of the contact lens is 50° smaller than the degree of the frame glasses. Therefore, the degree of contact lens should be determined according to the specific degree of the patient. There is a certain conversion ratio between them.

If the degree of myopia is below 300 degrees, the degree of contact lens is the same as the degree of the frame mirror. If the degree is between 300 and 500 degrees, the contact lens is 25 degrees smaller than the frame mirror. If the patient's degree > 500 degrees, contact lens degree is 50 degrees less than the degree of frame glasses, so should be depending on the patient's specific degree to decide how many degrees of contact lenses to wear, they have a certain proportion of conversion relationship.

If myopia is 300 degrees ° Below, the power of contact lens is the same as that of frame lens. If the degree is 300-500 ° In this case, the power of the contact lens is 25 less than that of the frame lens °。 If the patient's degree is > 500 °， Contact lenses are 50 degrees less powerful than frame glasses °， Therefore, it should depend on the specific degree of the patient to decide how many degrees of contact lenses to wear, and there is a certain conversion ratio between them.<br>
