Pencil Exercise

Hold a pencil arms length in front of you. Really focus on the tip of that pencil. Once you have it focussed, very slowly move it towards you whilst still maintaining the focus. See how close you can get it before losing this focus.

Swinging

Focus on a distant object, swaying gently from side to side. Do this for a few minutes every day, blinking as you sway. The blinking helps clean and lubricates the eyes, which is especially important if you spend a lot of time in front of a computer.

Clothesline

Japanese studies show that this exercise can significantly improve your eyesight if done regularly. Place a picture on a clothesline. Stand about a foot away from it and focus on the picture whilst it is (probably rapidly) moving. Move back a foot and repeat. Continue with this until you are about 10 feet away.

Candle Exercise

Eye sight is not just about your eyes. It is also about the eye brain relationship. Your brain must interpret what the eyes pick up. This exercise aims to improve the brain/eye connection.

Put your self in a quiet, dark place and look at a lighted candle. Focus your attention at the blue part of the flame and blink gently. After a minute or two try to imagine the lighted flame with your eyes closed.

If the visualization is not perfect, again look at the blue part of the flame and try to imagine the same without making any effort. When you are able to visualize the flame in your imagination open your eyes.

Colour Day

Choose a colour and look out for it throughout the day wherever you go. When you see the particular colour, be aware of it. Don’t bother concentrating on the shape of the object, just experience the colour and it’s subtle shadings. This again should help the eye/brain connection. Sunning

Try to do this daily. It may be difficult if you live somewhere like the UK! Close your eyes. Look directly at the sun through your closed eyes. While facing the sun, slowly rotate your head from side to side as far as you can. This gets the sunlight on the peripheral vision, and it helps bring more blood circulation to your neck. Do this for a few minutes. Enjoy the warming soothing feeling of the sun on your eyes.

Eye Massage

This exercise helps improve the blood circulation to the eye muscles.
