Prevent Myopia

21889590_ml_FotorThere are several ways to control the progression of myopia.

Good illumination
Animal studied showed that working under dim environment would increase the chance of having myopia. Thus, it is important to provide enough lighting for children. We suggest that the intensity of illumination should be at around 400lux.

Outdoor activities
Studies showed that children who spend less than 5 hours per week on outdoor activities, 60% will finally get myopic. Therefore, parents arrange some outdoor actives for their children, better 1 to 2 hours a day. It is beneficial to their general health as well as their eyes health.

Myopic control optical aids
Fortunately, the following is some myopic control optical aids are proved to be effective and safe in controlling myopic progression.

  1. Orthokeratology
  2. Daily disposable SOFT contact lens for myopic control
  3. Spectacles lenses for myopic control

Control myopia by medicine
Several studies show that atropine, a powerful toxic medicine for eye examination, can be used to slow down myopic progression. However, complications of using atropine are as following:

Short-term Complications 

  • Allergic conjunctivitis and blepharitis
  • Sensitive to light
  • Blur near vision
  • Eye pain
  • Fever
  • Having red rash on skin
  • Month and skin dryness

  long-term Complication

  • Lack of accommodation to near objects, lead to having presbyopia earlier than normal
  • Increase the chance of having UV light related eye’s problems and degeneration such as cataract and other retinal disease. 

We suggest atropine only for children fail other control methods.
