Cataracts – Natural Approaches to an Age-Old Problem

Is it possible to prevent cataracts or slow down their progression, or even reverse them?

Begin by protecting your eyes. UV light creates free radical reactions in the lens. Choose to wear sunglasses that filter 100% of the UV light and that wrap around to block as much light seepage as possible. Wearing a hat with a brim or a visor, particularly a visor that is dark on the underside can reduce UV rays entering from above and being reflected from below. This is important for everyone from young children to seniors.

The real base of nutritional protection is in antioxidants. Sadly, many of the anti-oxidant nutrients are oxygen-sensitive. What that means is by the time you get your veggies and fruits home from the market they have been off the vine long enough that the anti-oxidant levels are sagging sadly. I’m not saying ‘don’t eat fresh produce’ I’m saying ‘don’t count on it’ to do the complete antioxidant job. Be sure to eat at least a fist-sized serving of veggies for every 25 pounds of your body weight every day. That will give you a good base to build on. We’ll talk about antioxidant supplements more in a moment.

Read food labels. Cut out the junk food and anything that has an ‘ose’ ingredient. Junk foods and sugar-laden foods (even natural sugars) cause rapid oxidation in the body in general. Drink lots of purified water. The rule of thumb is at least one-half ounce of water for every pound of body weight.

Deal with sinus congestion quickly. There are excellent dietary and herbal ways to correct sinus issues. When the sinuses are congested they impede blood flow to parts of the eyes.

Use anti-oxidant supplements that include Vitamin A, beta-carotene, Vitamin C, and Vitamin E. The concentration of vitamin C in the lens is the second highest of any organ in the body. Some sources report that vitamin C not only prevents cataracts but can also reverse them. Bioflavonoids, specifically quercetin and rutin, make vitamin C more potent. Nature’s Sunshine’s Vitamin C with Bioflavonoids has both of these bioflavonoids. Low levels of glutathione, an antioxidant that your body can make from the amino acids l-cysteine, l-glutamic acid, and glycine, have been found in most people with age-related cataracts. Other nutrients that support glutathione production are n-acetyl-cysteine, alpha-lipoic acid, Vitamin C, Vitamin B2, Vitamin B6, selenium, and zinc.

In Traditional Chinese Medicine age-related cataracts are disturbances in the wood (liver) and water (kidney) elements. Using TCM herbal blends like K-C (Chinese Kidney Activator) and BP-C (Chinese Blood Builder) together can clear the liver energy and strengthen the kidneys.

More recently n-acetylcarnosine (an amino acid) has come up as a possible supplement to actually reverse cataracts. Used as eye drops in a product like Can-C, some people have found great benefit while others report no change at all, and some got worse. The big question to consider here is “what else was each of these people doing to support their eye health?” as it is unlikely that the eye drops or any nutritional supplements would be strong enough to counteract smoking a pack a day or eating a diet replete with low-nutrient foods.

In short, there are things you can and should do that are just plain good for your health that may also protect your vision well into your advanced years.

Natural Exercises For Vision Perfection

Staring, in addition to straining, is the more severe thing you can do to your vision. Following a long day at work, the eyes are exhausted and must unwind and renew to enhance sight. The unceasing strain day in and day out will help nothing other than harm the eyes.

The first exercise on how to improve eyesight is the Comma exercise. To do this, look for a dot on a page and focus on it making it as vivid as possible. Stare at the dot until it comes into focus. Odds are after a number of seconds the dot will in fact grow to be a lesser amount of clear and extra unclear.

Don’t stare; instead, let your eyes to gradually shift round the sheet, over and around the period. Don’t focus only on the comma, the eyes need movement. Make sure to blink a little.

Acuvue 2 Contact Lenses: An Overview

Acuvue 2 contacts are similar in design and features to the regular Acuvue brand lenses. They are best suited for people who wear contacts on a daily basis and who enjoy the sensation of comfortable, breathable lenses.

Their unique design makes them even easier to insert than the regular Acuvue lenses and of course, they are lightly tinted and come with “inside out” markings so you always know which way they are facing.

Acuvue 2: Superior Fit

These lenses have a reduced height on the edges which means the surface of the eye and the lens interact minimally providing exceptional comfort. They are suited for wear for up to two weeks and as a result of their lightweight design and frequent changing schedule, they are some of the best contacts on the market for your eye health.

Like all Acuvue products, Acuvue 2 lenses are made with UV protection. Many people do not realize that UV protection is as important for the eyes as it is for the skin. Corneal sunburn can occur with repeated exposure to bursts of UVA and UVB rays if the eyes are not adequately protected. These lenses are class 2 UV blockers, making them an excellent choice for even the most enthusiastically active wearers.

Vistakon, the subsidiary of Johnson & Johnson that manufactures this product, explains that more than 70% of Acuvue 2 wearers get better than 20/20 vision, according to clinical trials.

Having worn these contacts personally, I can attest to the fact not only do I have better than 20/20 vision but the comfort level is quite consistent throughout the day. In the past prior to this sort of technology coming out, the lenses would feel fresh and moist when you put them in, but as the day wore on, my eyes would start feeling drier and irritable.

This was due to the fact lenses then (and many even today) coated the outside surface of the lens with the wetting agent. The problem with this is with each blink, small portions of that solution wear away.

These lenses however employ a new technology where infusing the wetting agent inside the lens material itself gives it the ability to constantly provide an invigorating feeling all day long even in harsh and dry conditions.

These lenses are considered soft sphericals and since they are made from a hydrophilic or water attracting composite, they tend to absord moisture thereby keeping the contact soft and comfortable on the eye. Another key advantage with these lenses is unlike other lenses, these are precision manufactured in an identical manner giving you consistent, crisp vision each and every time you wear them.

It’s easy to see why these lenses are quickly becoming one of the nation’s leading choices for outstanding visual acuity, comfort and handling.

Lutein – Self Defense Against Blindness

As all of us age, we share many common experiences; one of which is deteriorating vision. One of the causes of this deteriorating vision is macular degeneration. This eye disease affects the mid part of the retina. There has been a recent serge in research on the problem probably because a great many of our population is approaching the age in life when we do not see as well as we did in the past. The lack of lutein in the diet may be a major cause of this problem.

Here in the United States the leading cause of severe loss of vision is macular degeneration in people over 65. This disease affects approximately 6% of the population between the ages of 76 and 75. There are over 16,000 cases reported each year and each year the number increases.

The occurrence of this problem is higher among white women and is not often found in people of color. Researchers have yet to determine the cause; although there is speculation among some scientists that exposure to sunlight and smoking contribute to the development of the disease.

Lutein helps protect the eyes from damage from blue light. This is because the macula is the area of the retina controlling central vision. It is the area most sensitive to blue light. Blue light is the part of the visible light spectrum that, along with ultraviolet light can damage the eye. This supplement protects the eye from damage by filtering blue light before it causes damage to the eye.

There has been research showing that there is a close relationship between lutein intake and pigmentation in the eye.

If you do not eat an adequate amount of foods containing lutein as you age you are risking blindness from macular degeneration. It is recommended by doctors that you have at least 6mg per day in order to maintain healthy eyes. The body does not produce it, therefore, you must replenish it constantly through the foods you eat. It is contained in dark leafy vegetables such as spinach and kale. But in order to consume enough of these vegetables to provide the recommended amount, you would have to consume over two bowls of raw spinach or kale every day.

Taking multivitamins might help, but many vitamins do not contain anywhere near the recommended amounts. In fact, one of the most popular multivitamins contains only.25 mg. That is 4% of the necessary amount. How much is needed daily? Research recommends at least 6mg per day for optimum results.

Right now there is no treatment for macular degeneration. There is research with lasers and experimental forms of surgery; however, they are very risky.

If you want to protect your vision in to your elderly years, it is important that you consume enough of this supplement to protect your eyes. Finding a vitamin that contains the recommended daily allowance will take some research, but will be well worth the effort. Multivitamins with more than an negligible amount of lutein are difficult to find, but with a little time and effort you can find one that will help you prevent blindness from macular degeneration.

The Importance of Sunglasses for Children

Sunglasses are considered by many to be a fun accessory; many adults even wear them as fashion statements. While sunglasses can be fun, they serve a very important role as well. Sunglasses protect your eyes! It is important to start children off right by insisting they wear sunglasses to protect their young eyes.

According to the American Academy of Ophthalmology, unprotected sun exposure can contribute to the development of cataracts and cancer. With this in mind, it makes sense to require from an early age that your child wear sunglasses. Children often spend a lot of time outside, making the amount of sun they are exposed to high. Aside from the benefits of protecting young eyes form an early age, requiring that your child wear sunglasses will hopefully be the beginning of a lifelong habit of eye protection.

Your approach to choosing sunglasses for your child will vary depending on the child’s age. But for all children, it is best to choose sunglasses that block at least 99% of UV rays or higher. Also, if you don’t already wear them, start wearing sunglasses yourself. In all aspects of parenting, it is wise to model the behavior you want; sunglass wearing is not an exception.

For babies, there are a wide variety of banded sunglasses available. The design is similar to swimming goggles. The band goes around the back of the head and helps keep the glasses in place. The band may not deter older babies from removing the sunglasses, but being persistent and consistently putting sunglasses on your baby will help your cause. Babies and toddlers love routines. Make putting on sunglasses a part of the “going outside” routine every time, and it will become second nature for them.

For older children, it is best to let them choose their own sunglasses, as long as the ones they choose offer the correct amount of sun protection. There are so many fun designs, including popular children’s characters, that it should not be difficult to convince an older child to wear sunglasses.

When choosing sunglasses for children, there are a few things to keep in mind. With all of the running around and playing children do, and the higher likelihood that a child might leave their glasses lying around, it is best to choose a more durable model. Polycarbonate lenses are recommended for children’s eyewear, as this material is more durable than other options. You might also consider some type of band or strap to help prevent your child from losing the sunglasses when they take them off.

Part of your job as a parent is to keep your child safe and help them learn to make good choices. Sunglasses will help protect your child’s vision, and getting them into this habit early will make protecting their eyes a normal part of their life. So, if you have not been mandating that your kids wear shades, start now. It is never too late to develop healthy habits, but the longer you wait the more difficult it will become.

The Importance of Eye Examinations

Think back to the last time you had your eyes examined – how long ago was it? If you are like many Americans, it was likely over two years ago. For some reason, we understand that getting a yearly physical from our family doctor is a necessity but getting our eyes checked every one to two years by our ophthalmologist or optometrist tends to be ignored. Getting routine eye exams is just as important as your yearly physical! Who should get their eyes checked? Everyone.

Children should go for their first eye exam from an ophthalmologist as toddlers and, if all goes well, their next exam should be around kindergarten or first grade. Adults should have their eyes checked every one to two years – depending on when their eyeglasses prescription changes.

Kids with undiagnosed vision care problems may have a trouble with their school work but probably won’t know to vocalize their vision impairment, mostly because they are unaware that they aren’t seeing normally. Children’s eye exams play a vital role in their vision development as well as their academic achievement. Since vision is closely linked with the learning process, if your child has not received a full, comprehensive eye exam by the time they hit first grade, take then to an ophthalmologist for an eye exam.

During an eye exam, your doctor will likely look for refractive errors – like nearsightedness, farsightedness, and astigmatism. Your eye doctor will also look for signs of Amblyopia – where one eye has turned a totally different prescription than the other eye; and also a whole host of other vision care issues and diseases. Given how dramatically the chances of developing an eye disease increase with age, it’s extremely important to have your optometrist or ophthalmologist examine your eyes regularly. Diseases like glaucoma and cataracts can be treated before progression occurs if caught early by your eye doctor. Your eye doctor may also check to if you have dry eye or have focusing problems.

While getting checked for new glasses may seem like less of a worry than possibly having glaucoma, checking your glasses prescription is actually just as important. You may not be seeing properly without even knowing it. Vision impairment has been known to cause car accidents, eye injuries, and could impair daily life – all because your vision hasn’t been checked for a new prescription in a while. To be on the safe side, make sure you see your eye doctor once every two years for an eye exam. If you notice your vision became a little fuzzy, don’t hesitate – go see your eye doctor.

Vision screenings are not a substitute for a proper eye exam. School nurses, pediatricians, and your local DMV may test your eyes in a quick vision screening but this is only done to see if you need a more comprehensive exam and it will not tell you if you need glasses. Only an optometrist or ophthalmologist can perform a comprehensive exam, give you a prescription for eye glasses or contact lenses, and fit you for a proper pair of eyeglasses frames.

Laser Sight Correction

Laser sight correction has become a safe and effective alternative to glasses or contact lenses for thousands of people. No matter how the eyeglass businesses have tried to make the “glasses look” glamorous in recent years, glasses are still an annoying encumbrance to active lifestyles. They only provide temporary band aids to an ever worsening condition. How many people can report an actual improvement in their vision because of wearing glasses. Typically, the eyesight gets worse and increasingly stronger prescriptions are required to maintain adequate vision.

Laser correction has continually improved in recent years and certainly provides a desirable alternative to glasses. It would be wonderful if there were a simple pill to swallow and “voila” no more vision problems. While not as convenient as a pill, laser procedures today are hardly less convenient than a bump in the road.

What is the most common type of laser correction?
The most commonly performed, and one of the best options for individuals who are wanting to get rid of the glasses, is, Lasik. This procedure is relatively quick, safe, and has very few side effects. While it may not promise perfect vision, at the very least, it can reduce a person’s dependence on glasses or contact lenses. The benefits of this procedure are tremendous, allowing people to more easily pursue their lifestyles-especially active lifestyles.

What is Lasik? It is a non-invasive, procedure which uses a beam of cool light to reshape the surface of the cornea, so that images will focus correctly on the retina at the back of the eyeball. The eye surgeon uses a computer to accurately calculate the precise amount of cornea removal for a given individual’s eyes. A pre-surgery exam is conducted and the eye surface is scanned and measured to obtain data which is fed into the computer which is used during the surgery.

How is it performed?
During the surgical procedure, thin steel blade is used to free a thin cellophane flap on the surface of the cornea, which is then pulled back to expose the under-layer of the cornea which receives the actual reshaping The laser, which is positioned into place, delivers a pre-programmed number of pulses of cool ultraviolet light onto the exposed under surface of the cornea. The pulses remove microscopic layers of cornea.
When the cornea has been reshaped, the thin cellophane flap is put back in place. It will adhere or re-attach to the cornea without the aid of sutures. The center of the cornea now has been altered to allow the incoming light rays to focus exactly on the retina so that images will be seen clearly. Most patients who receive this treatment notice a dramatic improvement in their vision immediately..

What is the follow-up protocol?
Following LASIK surgery, steroid, antibiotic drops, and artificial tears will be prescribed ensure proper healing. Maximum improvement usually occurs within three or four weeks. The final result is directly related to the post operative care given to the cornea after the surgery.
