Wang at 400 degrees in the right eye and left eye at 450 degrees of myopia and, more recently, he obviously feels a close perfectly, and came to the optical shop optometry, results show that myopia does not change, but with presbyopia to 200 degrees.

If the glasses really as good as the Merchant says, why he wore number does not apply yet? To solve this problem, not everyone is suited to wear "gradient multifocal" lenses.
Gradient more focus glasses and General single light glasses profile similar, but actually is completely different: lenses upper design into far with of photometric, lower design into near with of photometric, upper and lower part was design for a continuous of "transition district", wearing mirror who can through far with district and near with District respectively see far distance and near distance of objects, through Middle District see in the distance of objects. Gradient more focus glasses applies Yu has presbyopia or has depending on fatigue of crowd, especially teachers, and physician, and music workers, and computer operation personnel, appeared presbyopia phenomenon, not only needs see far, and near of objects, most time also to can see Blackboard, and Jean spectrum, and computer screen, middle distance of objects, a Deputy science custom of gradient more focus glasses can while meet far with, and near with and middle all distance of using needs. Part of young wearing multifocal Fake Oakleys Frogskins Sunglasses Cheap for Sale glasses of the gradient can also be used in patients with myopia diopter correction, effectively alleviate eyestrain.

This is some gradient multifocal glasses feel sick cause. easy carsick who or has inner ear disease of people may due to cannot tolerance depending on property of mild deformation and appeared dizzy, and nausea, and vomiting, symptoms, and hard in short time within adapted; gradient more focus lenses of reading district than General double light mirror location low, reading Shi must will head elevation party can makes eye Xia go to reading district, neck short, and cervical has problem of people often hard keep such of reading posture; also, has habits Yu near reading Shi bent back bow of people also more hard adapted the lenses. If one is visual fatigue occurred more than 40 years old, unwilling to wear reading glasses, wait for long-sightedness are two hundred or three hundred degrees and then select gradient multifocal glasses, we do not recommend that some patients wear, because at this point it's hard to adapt a gradient multifocal glasses.
