Yeah , due to retina detachment operation I did last time , my left eye prescription increase to -6.50 from -3.50 . I feel quite blurry on my left eye since the difference is about -3.0 . My right is condition is very good . Thank God , no detachment and the prescription in -1.0 . I totally depends on my right eyes now and hopefully my left eye will recover soon . I pray everyday for that :)
I went to hospital again and bought a new eye glass .What are the definition if the devices ? Eyeglasses and contact lenses are devices that correct refractive errors in vision. Eyeglass lenses are mounted in frames that are worn on the face, sitting mostly on the ears and nose, so that the lenses are positioned in front of the eyes. Contact lenses appear to be worn in direct contact with the cornea, but they actually float on a layer of tears that separates them from the cornea .
The purpose of eyeglasses and contact lenses is to correct or improve the vision of people with nearsightedness (myopia), farsightedness (hyperopia), presbyopia, and astigmatism
