Ten Things To Know About Contact Lenses

Ten Things To Know About Contact Lenses
 by: Michele Madsen
1. How hard is it to get used to wearing contact lenses?
Everybody adjusts to wearing contact lenses differently. How long it takes for a person's eyes adjust to wearing contact lenses varies and depends on the sensitivity of the eyes and also on the type of contact lenses being worn. Typically it will take from one day up to about two weeks.
2. How do you take care of contact lenses?
Proper care of contact lenses varies depending on the type prescribed. Disposable and extended wear brands are simply thrown away after they are used. Soft contact lenses and gas permeable lenses require more care to ensure longevity and to protect against infecting the eyes.
3. Do you have to be a certain age to wear contact lenses?
Age does not matter as long as the person wearing contact lenses can responsibly care for them. If not cared for properly, contact lenses can become damaged or lost, and they can become infected and cause serious injury to the eyes. Parents should be part of the decision making process.
4. Is it possible for contact lenses to become lost inside the eye?
This is highly unlikely. A contact lens can get stuck under the eyelid, making it difficult to find. If you have trouble locating your contact lenses, your eye doctor can help.
5. What is the difference between daily wear and extended wear contact lenses?
Daily wear lenses are inserted into the eye and removed each day. Extended wear contact lenses are made from different materials and allow more oxygen to reach the eye. Because of this, extended wear contact lens can safely be worn between seven to thirty days before removing, depending on the brand.
6. How do you purchase contact lenses?
Before you can purchase prescription contact lenses, you must get an eye exam and then have the eye doctor write out a prescription. You can get the prescription filled at many places, including retail outlets, doctors' offices and the Internet.
7. Besides daily and extended wear lenses, are other types of contact lenses available?
There are other types of contact lenses available including different colored contact lenses, bifocal contact lenses and lenses for astigmatism, contact lenses that block UV rays, special effect lenses, and more.
8. How will I know which type of contact lenses are best for my needs?
Your eye doctor can assist you in determining the contact lenses that are right for your eyes and for your lifestyle.
9. Are disposable contact lenses as good as daily wear contact lenses?
Yes, disposable contact lenses are just as good as daily wear. In fact, because of their shorter life cycles, they can be safer for the eyes because there is less opportunity for bacteria to develop and grow on the contact lenses. This decreases the chances for developing an eye infection.
10. After I get contact lenses, are follow-u p visits to the eye doctor required?
If you're new to wearing contact lenses, the eye doctor likely will recommend that you return after the first week of wearing the contact lenses. The doctor will make sure that the contact lenses are fitting properly and that they are being properly cared for. You should get reexamined for contact lenses every one to two years as well.

What You Need to Know Before Buying a Pedometer

What You Need to Know Before Buying a Pedometer
 by: Matt Ream
Question: What's small, weighs about an ounce, and comes in dozens of different models? Answer: a Pedometer.
Would you have guessed it had I mentioned this item can help you lose weight, decrease your chance of diseases like hypertension, diabetes, and heart disease, and improve your overall fitness? Using a pedometer to count your steps is one of the cheapest and easiest ways available to improve your health and fitness.
The tremendous variety of pedometers available today make it difficult for people who want the health benefits of a pedometer to decide which one is right for them. There are flip-down cases versus open-face units. There are those that just count steps versus those that count steps, distance, calories and time. Some pedometers come with lights, radios, alarms, step filters, scanning, pacing, auto start/stop, memory, voice, and on and on.
The most important thing to decide is what features you need. The basics are steps, distance, calories, and time. If you're doing a 10,000 step program or something similar, you will need to know your steps. They are the foundation for all other calculations within the pedometer.
If you are interested in knowing the distance you cover in your walking or running, get a pedometer with a distance calculation (in miles or kilometers, some have both). Make sure you can set your stride length or your distance measurements will be inaccurate. When walking or running, make sure you are actually taking steps the length you entered into the pedometer.
A pedometer that measures calories burned is helpful in giving you an idea of how much energy you have expended. If you are counting calories, this can be a good way to see if you've earned that extra doughnut or not. Again, make sure you can enter your weight to get the most accurate calculation possible.
The time function comes in a variety of forms. Some pedometers will show time of day, while some have a stopwatch or countdown timer. There are units that will start and stop only when there is movement, so you don't have to start and stop a stopwatch manually.
After features, another factor will be the physical properties of the pedometer itself. What sort of case configuration will work best for you? A flip-down case means the reset, and other, buttons are protected, and you flip down the case to see your steps. An open-faced pedometer is just that, open, and you have to look upside-down at your numbers. Not bad when you are checking steps, but it can be cumbersome if you are looking at a lot of data. Some pedometers have a holster-style case where you can pull the unit off your hip and look at it.
Consider where the pedometer is manufactured. There is general agreement that the best units are made in Japan, with Taiwan a close second. Pedometers made in China are generally believed to be less accurate than Japanese or Taiwanese models.
Price is always a consideration as well. The law of "you get what you pay for" works to a certain point, but is not the only guideline you should follow. I've heard of a few people who thought their free McDonald's or Kellogg's pedometers worked well, while most of the feedback I've heard was negative. I've also seen very expensive pedometers that just weren't worth the price.
It pays to shop around and find the pedometer that will work best for you. Consider the features, the structure, and the country of origin, then factor in the price. You will end up with a pedometer that will give you motivation to keep moving throughout your life.

Do You Want to Be Healthy? Then Get to Steppin!

Do You Want to Be Healthy? Then Get to Steppin!
 by: Dr. John Rumberger
From fat burning, to improved cardiovascular health, to improved recovery abilities, some aerobic work is recommended as an integral part of all training programs. Aerobic is a low-intensity, sustained activity that relies on oxygen for energy. This activity builds endurance, burns fat and conditions the cardiovascular system.
Improving the body's ability to process and deliver oxygen may improve stamina, not only in sports but also in every day life, doing any activity. To reach this goal, you need to strengthen and condition your heart because it is the organ that pumps oxygen-rich blood to the rest of your body. Like any muscle, the heart can grow stronger and more efficient by progressive demands in oxygen.
The aim is to develop bigger and stronger muscle units so that you can transport oxygen throughout the body with less effort and use more stored fat as energy. Increased oxygen consumption promotes overall health and increases metabolism resulting in burning extra fat stores. However, a mild activity can often just do the trick; it is not necessary to work up a heavy sweat.
Recent research results could hardly be clearer, when the subject of walking is brought up in the realm of exercise. Taking a walk is one of the best ways to take charge of your health. A study in the Journal of the American Medical Association showed that walking briskly for half an hour just six times a month cut the risk of premature death in men and women by 44 percent. Another study in the New England Journal of Medicine reported that men 61 to 81 years old sharply reduced their risk of death from all causes, including cancer and heart disease, by walking two miles a day. Other research has shown similar results for women.
Besides the well-documented health benefits, the beauty of walking is you can go at your own pace. If you are new to exercise or recovering from injury or childbirth, you can aim to walk for 20 to 45 minutes four or five days a week at the good fitness walking speed of three miles an hour. When (and if) you want to power up, you can take longer walks and work up to walking each mile in 15 minutes or less.
Once you are ready to hit the road (or the trail, track, treadmill or mall), how do you make the most of your walking workout? Here are a few tips and tricks:
Warm Up First, Then Stretch. Start by walking for just seven to 10 minutes (wear a watch) and then do a few gentle stretches. Your muscles will stretch better if you have warmed them up first. Ask a fitness professional which stretches are best for you.
Get Used To Walking. When you first start to walk, just walk. Take your time and get used to doing it again. Once your body has gotten used to the exercise it is time to improve and expand.
Take Short, Quick Steps. By taking short, quick steps, rather than long strides, you will work your glute muscles (in your buttocks) as you log miles.
Keep Your Head Up. Look about 10 feet ahead of you. Imagine you are wearing a baseball cap and have to look up just enough to see the road. This keeps your neck aligned properly.
Practice the Heel-Toe Roll. Push off from your heel, roll through the outside of the foot, then push through the big toe. Think of the big toe as the go button and push off with propulsion. Keep the other toes relaxed. (This takes practice.)
Smile and Have Fun. Learning these techniques takes time and concentration. Be patient and enjoy your workout. Dress comfortably, find a partner or wear a headset and listen to music you love and, if you're walking outdoors, vary your route.
Squeeze Your Glutes. Imagine squeezing and lifting your glutes up and back, as if you were holding a bill between them! This will strengthen your low-back muscles. Developing the ability to maintain this deep contraction throughout your walk will take a while.
Feel a hand on your back. Imagine as you walk that somebody has a gentle but pushing hand on the small of your back – mentally you feel as if you have a silent partner.
Pump Your Arms. Imagine you are holding the rubber grips of ski poles in your hands. Stand straight, drop your shoulders, squeeze your shoulder blades behind you and push back your elbows with each step. Keep your arm movements smooth and strong.
Zip Up Your Abs. During your walk, imagine you are zipping up a tight pair of jeans. Stand tall and pull your abdominal muscles up and in. You can practice this even when you are not walking.
Keep Your Chest Up, Shoulders Back. Use your walk as an opportunity to practice perfect posture. Imagine someone dumped ice down your back. That is the feeling you want to have as you hold your chest up and shoulders back.
Practice Mental Fitness. Do not replay the problems of the day while you walk. Try to maintain a state of relaxed awareness by paying attention to your breathing and noticing how your body feels. Visualize yourself getting healthier, stronger and leaner.
Consistency is probably the most important part of your walking workout. The more committed you are to walking all or most days of the week, the healthier you will be. Remember that short walks are better than none at all. The path to good health, like life, is a journey. All you have to do is take the first step.
