Soft Contact Lenses

Soft contact lenses are made of soft, flexible plastics that allow oxygen to pass through to the cornea. Soft contact lenses may be easier to adjust to and are more comfortable than rigid gas permeable lenses. Newer soft lens materials include silicone-hydrogels to provide more oxygen to your eye while you wear your lenses.

Rigid Gas Permeable (RGP) Contact Lenses

Rigid gas permeable contact lenses (RGPs) are more durable and resistant to deposit buildup, and generally give a clearer, crisper vision. They tend to be less expensive over the life of the lens since they last longer than soft contact lenses. They are easier to handle and less likely to tear. However, they are not as comfortable initially as soft contacts and it may take a few weeks to get used to wearing RGPs, compared to several days for soft contacts.

Extended Wear Contact Lenses

Extended wear contact lenses are available for overnight or continuous wear ranging from one to six nights or up to 30 days. Extended wear contact lenses are usually soft contact lenses. They are made of flexible plastics that allow oxygen to pass through to the cornea. There are also a very few rigid gas permeable lenses that are designed and approved for overnight wear. Length of continuous wear depends on lens type and your eye care professional’s evaluation of your tolerance for overnight wear. It’s important for the eyes to have a rest without lenses for at least one night following each scheduled removal.

Disposable (Replacement Schedule) Contact Lenses

The majority of soft contact lens wearers are prescribed some type of frequent replacement schedule. “Disposable,” as defined by the FDA, means used once and discarded. With a true daily wear disposable schedule, a brand new pair of lenses is used each day.

Some soft contact lenses are referred to as “disposable” by contact lens sellers, but actually, they are for frequent/planned replacement. With extended wear lenses, the lenses may be worn continuously for the prescribed wearing period (for example, 7 days to 30 days) and then thrown away. When you remove your lenses, make sure to clean and disinfect them properly before reinserting.

Decorative (Plano) Contact Lenses - Colored lenses

Some contact lenses do not correct vision and are intended solely to change the appearance of the eye. These are sometimes called plano, zero-powered or non-corrective lenses.

For example, they can temporarily change a brown-eyed person’s eye color to blue, or make a person’s eyes look “weird” by portraying Halloween themes. Even though these decorative lenses don’t correct vision, they’re regulated by the FDA, just like corrective contact lenses. They also carry the same risks to the eye. These risks include:

If you’re considering getting decorative contact lenses, you should:

• get an eye exam from a licensed eye care professional
• get a valid prescription that includes the brand and lens dimensions
• follow directions for cleaning, disinfection, and wearing the lenses, and visit your eye care professional for follow-up eye exams

Buying contact lenses directly over the Internet with a valid contact lens prescription is a great way to have your contacts delivered conveniently to your door. But you should also be careful of several things.

The following questions and answers should help you take simple precautions to make your purchase safe and effective.

What do I need to consider when buying contact lenses?

• Is your contact lens prescription current? You should always have a current, valid prescription when you order contact lenses.
• If you have not had a check-up in the last one to two years, you may have problems with your eyes that you are not aware of, or your contact lenses may not correct your vision well.
• The expiration date for your prescription is currently set by your state. Some require a one-year renewal, some a two-year renewal. If your state has not set a minimum expiration date, Federal regulation sets a one year date unless your eye care professional determines that there’s a medical reason for less than one year.
• To be sure that your eyes remain healthy you should not order lenses with a prescription that has expired or stock up on lenses right before the prescription is about to expire. It’s safer to be re-checked by your eye care professional.

What does a valid contact lens prescription include?

As defined by FTC regulations, a prescription should contain sufficient information for a seller to completely and accurately fill the prescription. This includes the following items:

• Patient’s name
• Examination date
• Date patient receives prescription after a contact lens fitting (issue date) and expiration date of prescription
• Name, address, phone number and fax number of prescriber
• Power
• Material and/or manufacturer of the prescribed contact lens
• Base curve or appropriate designation of the prescribed contact lens
• Diameter, when appropriate, of the prescribed contact lens
• For a private label contact lens, the name of the manufacturer, trade name of the private label brand, and if applicable, trade name of equivalent brand name

What can I do to avoid serious problems when buying my contact lenses?

Don’t Take A Chance on Using an Old Contact Lens Prescription!

Ask your eye doctor how often you should have check-ups. See the doctor regularly. The check-ups give your doctor a chance to check the fit of your lenses and change your prescription as your eyes change. Lenses that don’t fit can hurt your eyes.

Always contact your doctor for advice. A doctor can see early signs of damage that can lead to serious problems, even blindness. You may not notice these signs in their early stages.

Buying contact lenses

• Order your contact lenses from a supplier you know is reliable. Contact lenses are often more complex than they appear.
• Request the manufacturer’s written patient information for your contact lenses. It will give you important risk/benefit information as well as instructions for use.
• Beware of attempts to substitute a different brand than you presently have. While this may be acceptable in some situations, there are differences in the water content and shape between different brands. The correct choice of which lens is right for you should be based only on an examination by your eye care professional, not over the phone.
• Carefully check to make sure the company gives you the
  • exact brand
  • lens name
  • power
    • sphere
    • cylinder, if any
    • axis, if any
  • diameter
  • base curve
  • peripheral curves, if any

If you think you have received an incorrect lens, check with your eye care professional. Don’t accept a substitution unless your eye care professional approves it.

More and more jobs require the use of computers. With the information age being available on the computer, more and more people are spending endless hours in front of the screen. After a long day in front of the computer, it is common to start feeling tired, irritable, or pain in the eyes or head. Staring at computers and forgetting to relax and give the eyes a break can cause permanent damage and eye problems.

No one is expected to live a life without computers; we all need them and are use to them being a part of our daily lives. However, it is important to listen to our bodies and relax or take a break when necessary.

Listen to your body; it knows better than you do when it’s time for a break. Do not work until your eyes burn; you missed all the previous signs. Take short breaks every hour of work. This means get at least once every hour and walk around. However, taking breaks isn’t enough. Look away from the screen every 15-20 minutes for a minute or two. Look at things close and far away to allow the eyes to adjust and move around. The goal is to avoid the strain in the first place.

Blink as often as you can to keep the eyes lubricated. Take a few minutes to roll the eyeballs around; you can do this with your eyes open or closed to avoid looking silly. Open and close your eyes often to give them a short break. Yawn if you have too. Yawning stretches out the jaw muscles and keeps them from becoming tense causing headaches and eyes strain.

Move around as much as possible. You should always be in a comfortable position so adjust your body or chair as often as needed. Move the keyboard or monitor so you aren’t stretching your neck or looking at things at a strange angle. Try to avoid glare on the monitor, move it around as the sun moves or get a screen protector.

Keep the work area bright and well lit. Bright lights lighten up the mood and keep you feeling positive. Dim lights only bring down your mood and cause you to feel sluggish. Making minor changes in the work space and taking breaks often can keep long hours in front of the computer from permanently damaging the eyes.

Dr. William Bates spent years studying vision problems. He attended and graduated from Cornell University and became a teacher and researcher of ophthalmology in the New York area. Bates created many vision improvement methods and believed that anyone can see without glasses. His methods were developed teach the eyes ways to improve and heal themselves.           

The Bates Method was developed to help school age children absorb more knowledge without straining their eyes. Dr. Bates learned that most bad habits and eye problems begin in school age children. Children have a natural curiosity to learn new things. However, when material is constantly shoved down their throats and they are forced to memorize tons of uninteresting information, the mind gets tired and the eyes start to strain.           

Likewise, looking at new information causes the eyes to strain in order to commit it to memory. All day, every day children are forced to absorb new material, whether it interests them or not. They are not given a chance to allow the eyes to relax or take a break. This is where the Bates Method comes in.           

Bates’ Method is actually quite simple. He created a large chart full of common shapes and letters. The chart was placed on the wall in the front of the classroom and the children were encouraged to look over at the chart whenever they felt overwhelmed. Even looking at the chart for three minutes a day, takes the strain away from the eyes.           

The Bates Method was implemented in a few schools and the teachers noticed a vast improvement in concentration and progress. The eyes were able to relax and the strain was removed. Unfortunately, the school board felt the method was too distracting and the method is no longer in practice. In fact, China is the only country that teaches students vision training.           

The Bates Method can be used by just about anyone though. You could create your own chart and place it in your office. Glance at the card several times during the day to keep the eyes relaxed and alleviated the strain on the eyes. Training your eyes to relax will help improve vision today and for the rest of your life.

The exercises given here are of a type quite different from those recommended in the preceding article. They are designed to strengthen the power of accommodation, that is, the power of changing the focus of the eyes for vision at different distances, and will be particularly valuable to those who are either near-sighted or far-sighted.

Eye exersise 1. Shut one eye and look at a pencil point held five or six inches in front of the other. Now, look through the window at some point on the horizon or any distant object. After looking for two or three seconds at this distant point, focus the eye on the pencil point. If your eyes are normal you will be able to change the focus without any consciousness of effort, but otherwise you may experience very clearly the sensation of muscular effort in and about the eyeball. Muscular action, whether one is conscious of it or not, accompanies all changes of the focus of the eye, and the power of making these changes must obviously be improved by the daily practice of this  exercise.
 
Eye exersise 2. An eye-focusing exercise for both eyes. Look first at the point of a pencil held near by; then shift to a distant cloud, or some tree or building on the horizon. Immediately upon seeing the distant object, shift back again to the pencil point.
 
Eye exersise 3. A similar eye-focusing exercise, using one eye at a time. Close one eye by putting your hand over it. Look at the nearby pencil point or any close object, then at some distant object; return to the pencil point and continue. Change eyes and continue.

Eye exersise 4. Another eye-focusing exercise. Closing one eye, look at the end of the nose with the open eye, then at some distant point. Same with the other eye.
 
Eye exersise 5. A combination eyeball exercise and eye-focusing exercise. With your head held slightly upwards, first try to see the end of your nose. Then shift your gaze to some distant point for a moment. Look again at the end of the nose and continue, repeating only four or five times at first.

The exercises should be practiced with both eyes together, unless one is weaker than the other, in which case it may be necessary to practice the weaker one separately. At first you may not be able to see things very close to the eyes, but gradually you will find yourself able to diminish the distance. Begin by holding your pencil at whatever point you can see it most clearly, focus the eyes upon it for a moment, and then look at some distant object, such as a cloud, a tree, a house, or a chimney. You can vary the exercise, if you like, by looking at intervening distances, from a few feet up to fifty feet, one hundred feet, three hundred feet and so on. Then you can begin to hold the pencil point, thimble, needle, printed card, or whatever it is you choose to use, nearer to the eye. You will, in time, find that you can easily shift your vision from a distant object to your pencil or thimble held perhaps four or six inches in front of the eye, and see clearly and sharply at each distance.

A fairly good plan is to go to the window, and instead of using a pencil find some speck or imperfection in the glass which you can utilize as the nearby point, and then alternately shift the sight from this point to a cloud or distant tree.

Another plan is to throw the head back, shutting one eye, and with the other trying to see the end of the nose, afterward looking to the distance and then back to the end of the nose. This exercise, when practiced with both eyes together, combines the advantage of looking cross-eyed with those of rapidly changing the focus.

It is common logic that exercise of the eyes will strengthen these organs just as exercise of any other part of the body will strengthen that part.

Improving your eyesight through eye exercises and massages is not only beneficial, it will also act as prevention toward any eye conditions that you might develop.

Most people will be surprised, even amazed, at the improvement in the condition of the eyes, resulting from two or three weeks of proper exercise of the eye muscles. This does not mean that you should keep up this work for only two or three weeks. If you make it a daily routine you can expect to enjoy strong eyes and good vision to perhaps the end of life.

Try to perform all eye exercises without turning your head. 

Eye exercise 1. — Turn and stretch the eyes far to the left. Then turn and stretch them far to the right, continuing the movement back and forth from left to right ten times or more.

Eye exercise 2. — Turn your eyes upward, that is to say, look as far upward as possible without raising the head. Then, without moving your head, lower your eyes, looking as far down as possible. Continue raising and lowering your eyes ten times or more.

Eye exercise 3. — Raising your eyes, look upward diagonally to the left. Then lower them diagonally to the other side, looking downward toward the right. Repeat ten times or more.

Eye exercise 4. — Raise your eyes upward diagonally to the right. Then stretch them diagonally downward to the left. Continue back and forth ten times or more.

Eye exercise 5. — Roll your eyes around in a circle, to the left upward, to the right downward, so on around. Then reverse, rolling them the other way around. Continue until slightly tired.

Eye exercise 6. — Shut your eyes tightly and vigorously, squeezing your eyelids together as firmly as possible. Open and repeat ten times or more.

Eye exercise 7. — This is an exercise that should be performed without strain, and at first with only two to four repetitions at a time. Simply look cross-eyed as though trying to see the bridge of the nose with both eyes at once.

Eye exercise 8. - Starting from the left corner of your eye, moving down, trace an imaginary number 8 with your eyes. Reverse and repeat. Repeat ten times or more.

You will find that these exercises are very simple, yet very effective. You should practice them not once a day, but a number of times each day. You can practice them while dressing in the morning, while undressing in the evening, while out on your walks, while sitting in the car, or even while taking your meals. But you should set aside some particular time for this special purpose, whether it be morning or evening, else they are more than likely to be crowded out.

One of the most vigorous of eye exercises, and one extremely effective for gaining voluntary control of the muscles of the eyes, is the practice of looking cross-eyed. 

The fact is that the ability to look cross-eyed voluntarily indicates a good muscular condition and good control of the muscles concerned, and a person with a tendency to involuntary squint will find the practice one of the best ways in the world to correct that condition.

Eye Exercise Diagram No. 1

Eye Exercise Diagram No. 2

Another very simple method of exercising the eyes will be found in a system of following lines drawn within a large circle, or an imaginary system of lines based upon any diagram, such as those illustrated here.

Suppose that the circle represents the completerange of vision attained by rolling the eyes around. Imagine, then, that this circle occupies the space on the wall of the room, in front of you, that you can see by rolling your eyes around.

Then imagine a series of lines or a continuous line running from side to side, as in Eye Exercise Diagram No. 1, from the top of the circle to the bottom. Now, starting at the top, follow on the wall with your eyes just such an imaginary scheme of lines as that in the diagram.

Practice this a few moments with one eye first, then with the other, finally with both eyes together, and then go on to the exercise suggested in Diagram No. 2.

Eye Exercise Diagram No. 3

In Diagram No. 3 the eye starts in the center, then traces out a circular, or to be more exact, an imaginary spiral line, until the circling of the entire range of vision is attained. The head must not be moved.

If you follow the eye exercises offered in the photographic illustrations there will be no need of adding these imaginary line-tracing exercises. But you may find them interesting as a change.
