			<content:encoded><![CDATA[<p class="body-text"><strong>Periodic optometric examinations are an important part of routine preventive  health care. Many eye and vision conditions present no obvious symptoms.  Therefore, individuals are often unaware that a problem exists. Early diagnosis  and treatment are important for maintaining good vision and when possible  preventing permanent vision loss. </strong></p>
<p class="body-text">The need for and frequency of optometric examinations varies  with age, race, medical history, family history, occupation and other factors.  Individuals with ocular signs or symptoms require prompt examination. In  addition, the presence of certain risk factors may necessitate more frequent  evaluations based on professional judgement.</p>
<p class="body-text"><span class="header">SCHOOL-AGED CHILDREN</span></p>
<p class="body-text">Vision may change frequently during the school years. The  most common problems are due to the development and progression of  nearsightedness. In addition, the existence of eye focusing and/or eye  co-ordination problems may affect school performance. Periodic examinations are  recommended.</p>
<p class="body-text"><strong>At Risk:</strong> Children failing to progress  educationally or exhibiting reading and/or learning disabilities should receive  an optometric examination as part of a multidisciplinary evaluation.</p>
<p class="body-text"><span class="header">ADULTS</span></p>
<p class="body-text">During the adult years, the increased visual demands of our  technological society bring about the need for regular optometric care. While  the incidence of ocular disease is low for young adults, vocational and  recreational visual demands are significant. To maintain visual efficiency,  productivity, and optimum eye health, periodic examinations are recommended.</p>
<p class="body-text">Adults, beginning in their early to mid-forties, can  experience changes in their ability to see clearly at close distances. This  normal ageing change in the eye&#8217;s focusing ability will continue during the  forties and fifties. In addition, increases in the incidence of eye health  problems occur during these years. Therefore, periodic eye examinations are  recommended.</p>
<p class="body-text"><strong>At Risk:</strong> Individuals diagnosed with diabetes  or hypertension, or who have a family history of glaucoma, those who work in  highly visually demanding or eye hazardous occupations, those taking certain  systemic medications with ocular side effects or those with other health  concerns or conditions.</p>
<p class="body-text"><span class="header">OLDER ADULTS</span></p>
<p class="body-text">Individuals age 61 or older have an increasing risk for the  development of cataracts, glaucoma and macular degeneration and other sight  threatening or visually disabling eye conditions as well as systemic health  conditions. Therefore, annual eye examinations are recommended.</p>
<p class="body-text"><strong>At Risk:</strong> Individuals diagnosed with diabetes  or hypertension, or who have a family history of glaucoma or cataracts, and  those taking systemic medications with ocular side effects or those with other  health concerns or conditions.</p>

			<content:encoded><![CDATA[<p class="body-text" align="justify">General Overview</p>
<p class="body-text">Looking good is an important part of our lives. We wear the  latest fashions. Get popular hairstyles. Even have cosmetic surgery. And our  eyes are no exception. The verdict is in: People look better without glasses. In  a recent survey sponsored by Bausch &amp; Lomb, more than three times as many  adults surveyed thought that women looked better without glasses and more than  twice as many of the adults surveyed thought that men looked better without  glasses. Maybe that is why, increasingly, people are wearing contact lenses.</p>
<p>A contact lens is a hydrophilic (water-loving) disc that floats on your  cornea. There are dozens of options. Like prescription glasses, a contact lens  is specifically shaped to focus light into the retina of your eye (and to fit  your eye). But because it covers your cornea, it actually corrects your entire  field of vision (unlike glasses, which you can see over and under). Contact  lenses float on the tears that bathe the eye when you blink—so you want to keep  your eye hydrated and well-moisturized when you’re wearing contact lenses.</p>
<p><span class="header2">Sports Vision</span></p>
<p class="body-text">To be competitive on the playing field you need peak  performance from your entire body—and your eyes are no exception. Sports Vision  is &#8220;full-scope&#8221; primary eye care that can help you optimize three key visual  skills through contact lens wear, therapy, or treatment:</p>
<p class="body-text"><strong>Contrast Sensitivity</strong> lets you see fine  details from a distance—like the subtle contours of a golf course</p>
<p class="body-text"><strong>Dynamic Visual Acuity</strong> keeps your vision as  clear when you&#8217;re running as when you&#8217;re standing, so you can see every obstacle</p>
<p class="body-text"><strong>Focus Flexibility</strong> keeps a ball in sharp  focus as it moves toward or away from you</p>
<p class="body-text">Every sport has unique demands: depth perception, peripheral  vision, eye-hand coordination. And every sport poses unique challenges: glare,  wind, haze, and close encounters with moving objects. To win, you need to  conquer them all. Discover which visual skills are especially critical for your  sport. And why.</p>
<p class="body-text">Contact lenses are an athlete&#8217;s secret weapon. In most cases,  they may immediately improve your athletic performance. You can wear protective  eyewear over them—such as goggles or sunglasses. And you can quit worrying about  broken frames or lenses. Plus, contact lenses don&#8217;t fog up, slide down, or fall  off. That adds up to better vision when you need it most. Contact lenses can:</p>
<ul>
<li class="body-text">Increase peripheral vision</li>
<li class="body-text">Improve depth perception</li>
<li class="body-text">Enhance contrast sensitivity and color recognition</li>
<li class="body-text">Refine vision while in motion</li>
</ul>
<p class="body-text">Most athletes say that disposable contact lenses are the way  to go. You can replace them daily, bi-weekly, or monthly—whichever schedule  works for you. More comfortable. Less maintenance. Free of the protein deposits  that can cause irritation and decrease visual acuity. The bottom line: You see  better.</p>
<p class="body-text"> </p>
<p> </p>
<p class="body-text"><strong><a name="laser"></a></strong></p>
<p class="body-text"><span class="header">Alternatives to Laser Surgery</span></p>
<p class="body-text">Many individuals who need glasses look to laser surgery to  correct their vision problems. Eager to throw away their glasses, many people  rush into the decision to have laser surgery without considering other  alternatives.</p>
<p class="body-text"><strong>New, Excellent Contact Lens Alternatives to Laser  Surgery</strong></p>
<p class="body-text">You now have more choices than ever before for sharp,  accurate vision. Bausch &amp; Lomb is a leader in developing leading-edge  technologies for soft contact lenses.</p>
<ul>
<li class="body-text"><span class="header">PUREVISION</span> &#8211; the first contact  lens that can be safely worn 24 hours a day for up to 30 nights &amp; days-even  while you sleep. These revolutionary lenses allow oxygen to reach your eyes.  They&#8217;re so comfortable, you&#8217;ll forget you&#8217;re wearing them. Plus you&#8217;ll see  clearly all the time-even when you get up in the middle of the night. When worn  continuously for the 30 night wear period, say goodbye to cleaning and lens care  products.</li>
<li class="body-text"><span class="header">I-DAY Contact Lenses</span> &#8211; a daily  disposable soft contact lens that provides the ultimate solution for individuals  who want great vision and hassle-free eye comfort. With 1-Days, you replace your  contact lenses each day so you no longer need to worry about cleaning your  lenses. They&#8217;re an ideal option for people with allergies because one-day use  reduces the chance of the build-up of pollen and other deposits.</li>
<li class="body-text"><span class="header">COMFORT Contact Lenses</span> &#8211; cost  effective, extremely comfortable lenses worn for up to 30 days before  replacement. The name says it all! These popular lenses are comfortable and  offer superb vision right from the start.</li>
<li class="body-text"><span class="header">MULTIFOCAL Contact Lenses</span> are  disposable contact lenses that correct presbyopia, eliminating the need for  bifocal or reading glasses. Enjoy clear, natural vision at all distances,  whether you&#8217;re reading a novel or a faraway billboard. No need for reading  spectacles that instantly age you. Don&#8217;t compromise your active lifestyle!</li>
</ul>
<p class="header2"><a name="kids"></a></p>
<p class="header2"> </p>
<p class="header2">Contact Lenses: Good Choice for Kids?</p>
<p class="body-text">The biggest concern parents have about contact lenses for  their kids is, &#8220;Is my child old enough to wear contact lenses?&#8221; There is no one  answer. Physically the eyes can tolerate contact lenses at a very young age.  Some babies are fitted with contact lenses due to eye conditions present at  birth. And in a recent three-month study of 10 nearsighted kids who wore daily  disposable contact lenses, nine of the children wore the lenses without needing  their parents to help with putting them in and taking them out of their  eyes.</p>
<p class="body-text">What parents are really asking is, &#8220;Is my child mature enough  to wear contact lenses?&#8221; Only parents can answer that question. If you&#8217;re  considering contact lenses for your child, take a look at how your child handles  other responsibilities. If your child needs frequent reminders for everyday  chores, he may not be ready for the responsibility of wearing and caring for  contact lenses. But if he handles such duties well, he may be an excellent  candidate for contact lenses.</p>
<p class="body-text">Children are naturally great contact lens wearers if they  accept the responsibility for them. They adapt well to wearing the lenses due to  their flexible personalities. Kids also develop fewer complications than adults.  Younger people usually heal faster and have stronger immune systems. Plus,  children tend to follow instructions better than adults, so they have fewer  problems with overwearing the lenses or not using the correct care  solutions.</p>
<p class="body-text">Contact Lenses Are Great for Sports Sports and contact lenses  are a great combination for all athletes, including smaller athletes. Contact  lenses may be a safer vision option than glasses for recreation use.  Polycarbonate lenses are a must, but frames are more vulnerable to breakage.  Many contact lenses offer better optics than eyeglasses. Better peripheral  vision also comes from contact lenses, which leads to a superior  performance.</p>
<p class="body-text">Building Self-Esteem Contact lenses can do wonders for your  child&#8217;s self-esteem. Many kids would opt for contact lenses over glasses, mainly  for cosmetic reasons. They don&#8217;t like the way they look while wearing glasses.  Physical appearance can be dramatically altered by switching from glasses to  contact lenses. In many cases, this physical change prompts a self-confidence  and self-esteem surge in the child. School performance and participation may  also increase after switching to contact lenses. Amazingly, two thin pieces of  plastic may breathe new life into a previously reserved child.</p>
<p class="body-text">Keep in mind that switching your child from glasses to  contact lenses does not have to be a permanent decision. If your child does not  adapt well, or is not up to the responsibility of wearing and caring for contact  lenses, we will not hesitate to recommend glasses as a safer means for vision  correction.</p>
<p class="header2"><a name="tips"></a></p>
<p class="header2"> </p>
<p class="header2">Tips for contact lens wearers</p>
<ul>
<li class="body-text">Set a regular day for throwing away your old lenses and  replacing them with a new pair.</li>
<li class="body-text">Associate throwing away your lenses to a favorite event, for  example, watching &#8220;ER&#8221; or another television program, garbage day, etc. That  way, you&#8217;ll know that after watching &#8220;ER&#8221;, it&#8217;s time to throw away your old  lenses.</li>
<li class="body-text">If you follow a two-week replacement schedule, you might be  able to link throwing away your lenses to your pay day (as many people get paid  every two weeks). Find what works for you!</li>
<li class="body-text">Write your lens replacement date on your calendar. If you  have an electronic calendar, such as Microsoft® Outlook® or a PDA (e.g., a  PalmTM Pilot), program your calendar to remind you to follow your replacement  schedule.</li>
<li class="body-text">When you open up a new box of lenses, take a permanent  marker and write your &#8220;fresh lens&#8221; day or date on the individual lens packages,  e.g., Monday for one-week wearers or Saturday, for two-week wearers.</li>
<li class="body-text">Be sure to write yourself a reminder to order new lenses on  your last box. You may also be able to figure out when your lenses should run  out, and have your Eye Care Professional arrange to automatically ship you fresh  lenses before that date.</li>
</ul>
<p class="header2"><a name="dosdonts"></a></p>
<p class="header2"> </p>
<p class="header2">Do&#8217;s and Don&#8217;ts of Contact Lenses</p>
<p class="body-text">In order to help ensure crisp, clear vision, better eye  health and maximum lens wearing comfort, consider these important tips for  successful lens wear and care.</p>
<p class="body-text"><strong>Do: </strong></p>
<ul>
<li class="body-text">Wash your hands with a mild soap and dry them with a  lint-free towel before touching your lenses.</li>
<li class="body-text">Handle the same lens first to avoid confusing the right and  left lenses</li>
<li class="body-text">Clean, rinse, and disinfect your lenses each time you remove  them. Follow your eye care practitioner&#8217;s instructions.</li>
<li class="body-text">Apply hair spray before inserting your lenses.</li>
<li class="body-text">Apply make-up after inserting your lenses.</li>
<li class="body-text">Keep all solutions bottles closed when not in use.</li>
<li class="body-text">Use solution before expiration date marked on bottle or  discard.</li>
<li class="body-text">Clean your lens case daily and let air dry. Replace your  lens case every three months.</li>
<li class="body-text">Schedule regular appointments with your eye care  practitioner.</li>
<li class="body-text">Contact your eye care practitioner if you have questions or  concerns.</li>
</ul>
<p class="body-text"><strong>Don&#8217;t: </strong></p>
<ul>
<li class="body-text">Allow soaps, cosmetics, or other substances to come into  contact with your lenses.</li>
<li class="body-text">Touch the tip of a lens care solution bottle to any surface,  including your finger or the contact lens.</li>
<li class="body-text">Re-use any lens care solution.</li>
<li class="body-text">Use eye drops or solutions not intended for use with contact  lenses.</li>
<li class="body-text">Wear your contact lenses in the presence of harmful or  irritating vapors or fumes.</li>
<li class="body-text">Apply eye make-up to the inner portion of your eyelids.</li>
<li class="body-text">Use eye make-up that is likely to run into your eye.</li>
<li class="body-text">Share or borrow eye make-up or applicator brushes.</li>
</ul>
<p class="header2"><a name="makeup"></a></p>
<p class="header2"> </p>
<p class="header2"> </p>
<p class="header2">Make Up and Contact Lens wear</p>
<p class="body-text">Since minor allergic reactions can prevent you from wearing  your contact lenses, take special care in choosing and applying make-up around  your eyes.</p>
<ul>
<li class="body-text">Look for products labeled hypoallergenic, for contact lens  wearers or for sensitive eyes.</li>
<li class="body-text">Put in your lenses before applying make-up.</li>
<li class="body-text">Remove your lenses before removing make-up.</li>
<li class="body-text">Never apply eyeliner to the inner edge of the lid.</li>
<li class="body-text">Replace make-up every three to four months; that&#8217;s when the  preservatives expire.</li>
<li class="body-text">Never share eye make-up with anyone.</li>
</ul>

			<content:encoded><![CDATA[<p class="body-text"><strong>Glass</strong><br />
Glass was the first material to be used for spectacle  lenses, and for many years was the only option available. They provide good  vision correction and are scratch resistant, but compared to plastic material  they are heavier and not as impact resilient. Although glass lenses can be  chemically treated to increase durability, they can shatter if accidentally  dropped or hit by blunt force.</p>
<p class="body-text"><strong>CR-39 Plastic </strong><br />
The most common type of  plastic spectacle lens material, CR-39 is made from a hard resin that is lighter  and more impact-resistant than glass. Compared to glass, this material has a  softer surface so a scratch coating (preferably applied at the time of  manufacturing) makes the lenses more resistant to scratches appealing. The  higher refractive index* allows the material to bend light to a greater degree,  meaning that less curvature is needed to achieve a specific prescription power.  Since less material is being used, the lenses are consequentially lighter. In  order to maximize the benefits of high-index lenses, they should always come  with a scratch coating for protection and an anti-refection coating for better  clarity. A simple rule of thumb: the higher the index number, the thinner the  lens.</p>
<p class="body-text"><strong>Aspheric Plastic</strong><br />
Aspheric lenses provide  visual and cosmetic benefits for stronger prescriptions. Unlike spherical  lenses, aspheric lenses flatten progressively from the center to the edge. This  results in enhanced overall vision, reduced thickness, and decreased peripheral  visual distortion. When used for high farsighted prescriptions, they make eyes  look more natural instead of magnifying them into “bug eyes.” Those with strong  nearsighted prescriptions benefit from thinner lightweight lenses. Aspheric  lenses can be ordered in high index materials for the ultimate in attractive  thin lenses.</p>
<p class="body-text"><strong>Polycarbonate</strong><br />
These lenses are one of the  most impact-resistant materials available, and they naturally filter out UV  light. When vision has been significantly impaired in one eye, polycarbonate is  used to better protect the good eye from impact damage. These lenses are the  optimal choice for children, industrial safety, and sports glasses.  Polycarbonate lenses are considered a high index material as they are thinner  than CR-39. Polycarbonate lenses should always have scratch-resistant coating on  both the front and back surfaces to protect its surface and prolong the life of  the lens.</p>
<p class="body-text"><strong>High Index Plastic</strong><br />
A variety of new  plastic materials bend light more than conventional CR-39 lenses. High index  lenses provide significant advantages over traditional plastic or glass. They  are made of a denser resin material that makes high nearsighted prescriptions  thinner, flatter, and lighter. It eliminates the thick “coke bottle” effect of  high nearsighted prescriptions and the “bug eye” effect of high farsighted  prescriptions. The process improves peripheral vision, filters out UV light  (both UVA and UVB), and makes the lenses more cosmetically</p>
