There are many forms of spectacles that are touted to reduce eye strain, for example, when using the computer for a prolonged period of time. These forms of spectacles usually involve various anti-reflective lens coatings that reduce glare and improve contrast.
However, there is no evidence that they can be useful in preventing or slowing down the development of myopia in children. Unfortunately, these forms of spectacles definitely cannot reverse myopia in adults.
With respect to children and slowing the progression of myopia, only the use of Atropine eyedrops or Ortho-Keratology lenses has been shown to demonstrate efficacy in myopia prevention.
