Changing myopia: Briefly, there is not way to permanently correct myopia without surgery. Myopia is due to the combination of the eye length, the corneal steepness (refractive power) and the lens. To change myopia, one or more of these would have to be changed. Optometrist with variable success use contact lenses sometimes to temporarily change the eye surface and myopia. Corneal or lens surgery are needed. ...Read more
Can plus lens therapy reverse/cure myopia? I'm seeing improvement with that, if it can't then why its improving mine?
May be temporary: Myopia is usually caused by an abnormally shaped eyeball. Since it's a structural abnormality, using a lens wouldn't be expected to permanently cure it. It's possible that the lens may be training you to focus better for short periods of time, i suppose, but the only cure for myopia that i'm aware of is surgery. Perhaps one of my opthalmology colleages might have more info for you. ...Read more
Can plus lens therapy reverse/cure myopia? I'm seeing improvements with that and many peoples have reversed theire myopia too.
Possible, not likely: While it is possible, high myopia tends to progress somewhat as we age, rather than reverse, although it can happen. As long as the condition continues to progress, the best option is to keep up with glasses or contact lenses. If and when the prescription stabilizes, you may wish to consider lasik surgery, if you are a candidate. ...Read more
Will lenses with a small positive value like say +0.5 help reverse some degree of myopia over time?
Nearsightedness: In this error of refraction, the eye behaves as if it is too long and the natural focal point is in front of the retina (the film that you see with at the back of the eye). The eyeglass to correct this is a minus lens which disperses the light and pushes that focal point back onto the retina. Most myopia gradually increases through the teens years and stops in the 20's. ...Read more
Depends on age: There is some information that use of certain eyedrops during childhood may be able to slow progression of, but not cure, myopia. After age 21, with stable readings, one can consider laser refractive surgery (i.e. Lasik or prk) if the affected individual does not want to wear glasses or contact lenses to correct the myopia. Myopic eyes are at higher risk for glaucoma and retinal detachment. ...Read more
