Can vision therapy slow down Myopia? PowerPoint PPT Presentation

Can vision therapy slow down Myopia? - Myopia commonly known as nearsightedness or shortsightedness is the inability to see far objects or images clearly. A person with Myopia will find it difficult to see road signs, the television or a clock on the wall. While both adults and children are at risk of myopia development and progression, 40% of the people affected are under the age of 17. Myopia is the condition in which the axial length of the eye grows too long or the cornea or eye lens becomes too curved relative to the eyeball length. Instead of focusing on images directly on the retina, a myopic person will focus on images in front of the retina which can result in blurry distant vision. | PowerPoint PPT presentation | free to view

Effect of Ortho-K Lenses on Myopia Progression for Kids PowerPoint PPT Presentation

Effect of Ortho-K Lenses on Myopia Progression for Kids - Myopia is one of the refractive errors that is getting common in children due to the drastic changes in their lifestyle. The condition in which distant objects appear blurry is caused by the elongation of the eyeballs or an abnormal shape of the cornea or lens which causes the retina to prevent incoming light from directly focusing. Orthokeratology or Ortho K lenses are a proven way to slow down the progression of Myopia in kids and achieve better outcomes compared to single-vision lenses. | PowerPoint PPT presentation | free to view
