Some eye health professionals insist that it is impossible to improve eyesight naturally, other experts believe that certain foods and practices can help you see better. Here’s what we know so far.

Young children are often overprescribed glasses, I learned. A study found that nearly 20% of preschoolers screened by paediatric ophthalmologists were prescribed glasses.

Dr. Bates believed glasses and contacts made vision problems worse nearly a century ago. He founded the Bates Method, a relaxation-based alternative therapy.

Our modern lifestyle requires unnatural eye movements. Here are some eye-strainers. -Long, small-print reading. -Dim or artificial light (or insufficient natural light!)

How to Do Eye Relaxation Exercises -Warm your hands, then place them over your eyes for 10-20 seconds. Shoulder-width apart. -Keep hips still while rotating upper body and swinging arms.

Here are a few great nutrients that increase eye health: Omega-3 fatty acids. Fatty fish and fish oil are great sources. Vitamin A. Think orange foods, like carrots and sweet potatoes.

Lutein. Leafy greens, like kale and spinach, are best. Vitamin C. Get lots of hearty veggies like cauliflower, broccoli or even sweet yellow peppers to get a good dose. You can also supplement with vitamin C.
