Reading Glasses Are Optional

Recent statistics reveal that one out of ten women between the ages of 40 and 65 wears reading glasses. If you already wear glasses or contact lenses, then bifocals might be in your future. If you are like most women, this is not an event to look forward to.

In what is considered the �normal aging processes�, the lens of your eye begins to stiffen as the years go by. As the lens becomes less flexible, it becomes more difficult to focus on something close. This is a form of farsightedness called presbyopia. This condition is generally corrected with reading glasses or bifocal lenses.

There are also several age related eye diseases that can occur over 40. Most serious eye diseases are painless, and show no symptoms for years. Only a qualified professional can detect and diagnose them before they cause permanent damage.

Glaucoma is one of the most common eye diseases. Glaucoma causes almost 12% of all blindness in the US. Increased fluid builds up within the eyeball, causing pressure. This pressure, over time causes irreversible damage and blindness.

Cataracts are caused by a build up of protein on the lens of the eye. Over time, the lens turns milky white, and clouds vision. The lenses then need to be surgically replaced to restore vision.

Macular Degeneration results in the loss of sharp vision. The macula is the part of your eye that is responsible for sharp focus, and bringing things clearly into view. The cause of this condition is still unknown, and it generally affects people over 60.

Like all other parts of your body, your eyes respond favorably to great nutrition and exercise. Optimum nutrition for your eyes includes proper amounts of Vitamin A, C, and E, as well as the minerals selenium and zinc. These nutrients are found in fresh fruits and vegetables, especially in yellow and yellow-orange foods like yams, cantaloupes, and carrots.

A growing number of vision therapists believe that a series of eye exercises done daily can help keep your eyes younger. Common sense tells us that exercise is important for all the muscles in the body, and the eye muscles are no different.

There are several hundred various exercises for your eyes, and no single exercise can offer the solution to every vision problem.

One you can try if you work at a computer all day is to tack a piece of newsprint to the wall, about 8 feet away from your computer terminal. Interrupt your work every 15 to 20 minutes, and focus on the newspaper, then back to your computer screen. Do this several times daily. This exercise can help prevent the blurry vision that some people experience at the end of their workday.

Deteriorating vision does not have to go along with the aging process. If owning a pair of reading glasses, or bifocals is the last thing you want to do, then it�s time to focus on prevention.

Do You Have Any Eye Disorders Too?

Do You Have Any Eye Disorders Too?

Have you ever though that you are having some eye disorders? If so, prescription eyeglasses is one of the ways you can go for. Actually, the need for prescription eyeglasses can come from several different eye conditions. The most common eye disorders are Farsightedness, Nearsightedness and Presbyopia.

Nearsightedness, also known as Myopia, is supposed to be the most common eye disorder these days. It happens whenever the light focuses in front of the retina instead of focusing on the retina. Blurred vision on objects that are in the distance is the main symptoms for Myopia. When you squint the eyes, you can see the object clearer. This vision can be corrected by using prescription eyeglasses with a bifocal or trifocal lens.

Farsightedness, or called Hyperopia, is very different from Myopia. The light focuses behind the retina rather than in front of the retina. One of the common symptoms of Hyperopia is your eyes will feel more tired from reading or having headaches. In fact, it is pretty difficult to see things clearly that are within a short distance. As for the children, having crossed eyes is the most common symptom for them. Fortunately, this eye disorder can also be corrected by wearing prescription eyeglasses.

Apart from above mentioned, Presbyopia is another type of most common eye disorder that can be corrected by wearing prescription eyeglasses. This disorder is where the lens or eye cannot focus. Actually, this usually happens to us when we become old. The common symptoms for Presbyopia are that people finds themselves have to read newspaper or other reading materials farther away in order to see clearly. Moreover, eye fatigue is a common symptom.

As a matter of fact, it is very important to get regular eye exams in order to make sure your eyes are in good conditions. Or else, it is highly to get worsen later on.

During the eye exam, the optometrist will also give you a glaucoma test. Glaucoma is the build up of fluid on the eye that will pressure the retina. The feeling is irreversible if left untreated, and can cause total loss of sight. It is very dangerous and this is the one eye disorder that cannot be treated by wearing prescription eyeglasses. However, this condition rarely has symptoms, therefore the importance of routine eye exams cannot be overstated.

Weblog comments: Glaucoma and photography

Glaucoma and photography posted 15th January 2006

• Sorry not some wonderful cure, but instead a few sites that might be of interest. First up is the Glaucoma Research Foundation website. Designed by Mule, it’s a really fresh approach at what a charity site can look like. And of course the nature of the site means that accessibility is very much to the fore. The site viewing widgets are an obvious point, with options for text size, contrast and layout providing configurable zoom layouts.
  On this note there a couple of passages in the site accessibility statement that I would like to highlight:

  The needs of low-vision users are too diverse for simple solution. No one solution, in terms of what colors to use, what type size to use, what screen layout to use, would meet the needs of all the low-vision users we worked with.

  Overall, we found that, with a few very specific additions, good design practices recommended for accessibility are simply good design principles, more strenuously worded.

  Two points here: low-vision users have differing requirements (hence the array of options provided) and good design is good design, whoever the primary audience is.

  We do not display accessibility-standards approved badges. Tools such as Bobby do not give a complete picture of the sites accessibility in practice. A website might pass all possible validators and still provide a very bad experience. The evaluation tools are a means, rather than an end to themselves.

  Our target is to meet all WAI guidelines through Level 2 priority and Section 508 guidelines, which are a subset of the former. However, we will favor good design principles over specific technical guidelines that may apply only to current technology.

  Amen to that. This is very much the approach we take at Clearleft – guidelines and validators are useful tools and help ensure the basics are in place, but they can never be the final story.
• And so to the photography bit, by which I mean photographs in web pages. First of all a quick pointer to a long-awaited tweak in Flickr. The photostream widget, which shows previous and next photos, will now scroll through the photostream enabling you to skip the next photo and preview the next-but-one photo, and so on. A simple addition but a clear improvement – I love the way sites like Flickr continuously tweak the interface and application, accepting that it should be a natural part of site evolution.
  A similar, albeit simpler feature can be found on the @media 2006 site where a series of photos from the 2005 event are provided with a neat scroller. The bit I particularly like about this is the integration of the photo into the liquid design. Vivabit have chosen the cropping approach, with overflow:hidden applied to the paragraph containing the photo. The paragraph itself has a coloured background to maintain visual integrity on wide windows.
  And finally to Cabel Sasser’s newly released blog. Cabel is co-founder of Panic, the makers of Transmit, and is responsible for such cool JavaScript gubbins as Panic’s drag and drop shopping cart. Well check out the nicely done zoomable photos. The treatment may not be entirely original or unobtrusive, but it’s still cool, effective and degradable. And from the comments I see Lightbox JS is another cool approach to photo zooming.

Glaucoma-the silent thief of eye sight

Glaucoma-the silent thief of eye sight

One of the leading causes of blindness in the world is Glaucoma. Nowadays Glaucoma is not uncommon in adults of the age of 40 and above. It is imperative on our part to have a basic knowledge regarding how this silent thief steals away our vision and how it can be scientifically prevented ,controlled and treated. It is a condition that causes loss of vision resulting initially in loss of sight partially and in many cases culminating in total blindness. Early diagnosis and regular proper eye care and treatment prevent further loss of vision.
