Nutrition and Your Eyes – How Antioxidants Can Save Your Vision

Author | 28.08.2007 | Category Eye Nutrition

When you think of the benefits of eating healthily, you probably think of strong muscles, sturdy bones, and high energy levels.  However, good nutrition can also be the key to saving your eyesight.  The same diet regimen that has been shown to reduce the risk of cancer can also dramatically lower your chances of contracting the number-one cause of blindness - macular degeneration.

The nutrients that are most effective at reducing the risk of contracting macular degeneration as you age are known as antioxidants.  Oxidation is the chemical process that causes iron to rust, fruit to brown when exposed to air, and oil to turn rancid.  The same process occurs in our own bodies, when molecules called free radicals strip electrons from other molecules in our bodies, damaging otherwise healthy cells.

Free radicals are a natural result of our metabolic processes, and are impossible to avoid altogether.  However, they are countered by antioxidant nutrients in our bodies.  They only do real harm when the level of free radicals outpaces the amount of antioxidants in our system.

Remember when your parents told you that eating carrots is good for your eyes?  It turns out, they were absolutely right.  Carrots and other orange vegetables are a vital source of eye-healthy antioxidants.  So is spinach, as well as other leafy green vegetables. Diets that are high in polyunsaturated fats and sugars can greatly increase your chances of getting macular degeneration. 

A five year study showed that people who consume high levels of antioxidants have only 25% of the risk of contracting macular degeneration, and resulting blindness, when compared to a study group.

Some of the most important antioxidants when it comes to our eyesight are the vitamins C and E, beta carotene, and the mineral zinc. 

How to Insert Contact Lenses

Author | 10.08.2007 | Category Contact Lenses

One of the reasons that people sometimes shy away from using contact lenses is that they are nervous about being able to insert the lenses.  After all, the thought of touching your eyeball is disturbing to many people.  However, the insertion process is easy to learn, and veteran contact lens users can do it without thinking about it.  Here is a quick guide to show you how to insert contact lenses yourself.

1. Wash your hands and dry them thoroughly.  You want to be sure to remove any debris that could contaminate your lens.  If your hands are damp, the lens could stick to them, making it difficult to insert.

2. Remove the contact lens from its case and rinse it briefly with saline solution to make sure that there is no dust or dirt on it that could irritate your eye.

3. Examine your contact lens to ensure that it is right-side out.  It should have a smooth, even curve; bulging is an indication that it is inside out.  Depending on the brand you use, there may also be a word or logo that should be readable from the outside.

4. Position the lens on the pad of your index finger.

5. Add just a tiny drop of saline solution to the inside of the contact lens, to make it easier to insert in the eye.

6. With your other hand, pull your eyelid gently upwards, and hold it so that you cannot blink.

7. Use the middle finger of the hand with the contact on it to pull the same eyelid slightly down.

8. Look straight ahead into a mirror so that your eye does not move. 

9. Gently move the contact lens over your eye.  When you get close enough, the lens should move from your finger to your eye.

10. Release and close your eyes for a few seconds, to ensure that the lens stays in place.

Voila!  In just ten easy steps, you’ve inserted your contact lens!

How Progressive Lenses Work

Author | 03.08.2007 | Category Contact Lenses

One of the unfortunate side effects of aging is that the crystalline lens in the eye loses some of its flexibility, making it difficult to focus on objects at different distances. Bifocal lenses were an attempt to help people focus by creating two separate zones in the glasses with different strengths that allowed people to focus on objects both close by and at a distance, but this still left the middle distance unclear. Read how progressive lenses work to provide a better solution for people who suffer from this problem.

Progressive lenses have a gradient corrective range, with the top of the lenses having only minimum strength and the bottom reaching the maximum prescription strength. Patients can bring objects at any distance into focus by moving their heads until they find the right correction strength for the object.

Progressive eyeglass lenses have many advantages over bifocals or trifocals including:
• There is no sudden, dramatic change from one zone to the next, which makes for a smoother transition between focus ranges.
• The proper focus in any range from far to near can be easily achieved.
• Glasses with these lenses look more attractive, and are not immediately identifiable as multifocal lenses.

While progressive lenses are the most effective way of dealing with age-related focus problems that we have today, they do have drawbacks as well. Most notably, the variety of different focuses can be disorienting for some people. Progressive corrective lenses are most effective when looking directly at an object; objects that are seen off to the side will appear to be distorted. While most will adjust to the lenses with time, some people simply cannot tolerate the distortions.

If you are currently using bifocal or trifocal lenses, progressive eyeglasses may be a huge improvement for you. Speak with your eye doctor to try these remarkable lenses.
