Natural techniques that can improve eyesight include maintaining a healthy diet, taking breaks during work, getting enough sleep, and performing eye exercises, according to Natural Vision Improvement. Massaging and applying heat to eyes also helps preserve their health.
Adopting a diet rich in vegetables, fruits and anti-oxidants helps to prevent eyesight from deteriorating, claims Natural Vision Improvement. Minerals and vitamins A, C and E also support the health of the eyes. Taking a 10-minute break for every hour spent in front of a computer screen helps counter eye strain. Getting eight hours of sleep rests the eyes and helps improve eyesight.
