Using 2WIN-S portable refractor for amblyopia screening
2WIN-S portable refractor
All participants will be tested by 2WIN-S portable refractor without eye dilatation. If the 2WIN-S reports non-referral, participant will be tested visual acuity by optometrist. If the 2WIN-S reports referral, participant will be tested cycloplegic refraction by pediatric ophthalmologist, then tested by 2WIN-S again. The participant whose result is abnormal will be referred to the hospital for further management.
