Commonly known as nearsightedness, myopia is typically when you can see well at near, but have difficulty at distance without glasses or contacts. It occurs when the shape of the eye is longer than normal or when the cornea is too steeply curved.
Myopia progression in children can pose risks such as retinal detachments, macular degeneration, glaucoma, and cataracts. In these cases, there are many options of myopia control to slow the progression.
There is no cure for myopia, but lenses can improve vision to help reach optimal visual acuity. Myopia control is a set of treatments to prevent myopia progression in children. It usually includes progressive-lens glasses, specialty contact lenses, and a low-dose of an eye drop called atropine. When it comes to wearing glasses all the time, it depends on each individual and their age.
Astigmatism is the most misunderstood of all refractive errors. Put simply, it is when the eye has two prescriptions, causing blurred vision at both distance and near. Its symptoms are sometimes described as lights stretching diagonally at night or the appearance of shadows when looking at objects. Astigmatism is caused by an eye that is shaped slightly oval instead of round.
