Some myopic patients due to past without adjustment, after wearing corrective glasses, suddenly hired regulation, and to adjust to the new normal or near normal relationship, often feel uncomfortable collection occurs, or even visual fatigue.
Correction of myopia, in principle, to achieve the best at the lowest refractive vision given prescription, For example: a 1.25D, a 1.50D, a 1.75D, vision correction can make up to 1.5, when given to a 1.25D. Because diopter myopia often feel deep diopter lens than light lenses seem clear. If negligence is easily corrected salvation, salvation often used to adjust to compensate, resulting in myopia hyperopia into a man-made, multi-use regulation is bound to make over- regulation, the relationship is less than the set greater than the set upside down, and Discount Oakleys Flak Jacket Sunglasses Cheap causing eye fatigue, lack even can contribute to the development of myopia.
Where 2.00D of myopia in one of the following may be completely corrected, a 4.00D 2.25D ~ a discretion to reduce a 0.25D; an 4.25D ~ a discretion to reduce 6.00D 0.25D ~ 0.5D ; an 6.25D ~ 10.00D a discretion to reduce a 0.50 to a 1.00D, a 10. OOD more discretion to reduce a 1.00D a 2.00D. When given a prescription based on the patient tolerance of 2 to 3 times, each separated by 3 to 6 months, the last time to give full correction prescription, the patient should be invited to look at his eyes with eye chart, without affecting the patient with far vision requirements eyes while subtracting the appropriate diopter, so that both the regulatory function of the ciliary muscle workout, but also make the regulatory function of the relationship between the collection gradually changed to normal relations, in order to achieve adaptation. Children under 15 years old, its tolerance and resilience are strong, can be considered a given.
The general principle is: mild myopia can be a full correction. Moderate myopia may reduce it, twice correction; generally it is appropriate to achieve the best vision of the lowest degree lens to prevent excessive correction. Initial wearing adult degree to reduce it to reduce the wearer's head does not faint bulge, walking convenience as well. High myopia may wear corrective Tiffany and Co Key Necklace Jewelry Outlet lenses when fully as far, as close should subtract 1 / 3, more than 45 years old, as near as the degree to subtract, so with two pairs of special mirrors.
