• Whether to wear contact lenses or not is a big decision and it's one that should be well thought out. This type of cosmetic enhancement, while beneficial in most cases, can lead to the onset of serious eye and vision trouble if maintenance guidelines are not strictly adhered to. It's not that contact lenses require a considerable or complicated amount of maintenance, but ensuring that the lenses are properly cleaned and stored does take a few minutes, every single time the lenses are worn.
• The cornea is a clear layer that completely covers the part of the eye that has color. Ideally, the shape of the cornea is round, like a tennis ball. The cornea's job is to bend rays of light that enter the eye so that these light rays can be better focused on the lens enabling the retina to produce a clear image.
• Bifocal contact lenses are becoming more popular with each passing year, especially as the elderly strive to fight the signs of aging. Like the eyeglass lens, each bifocal contact lens actually includes two different prescriptions. One of the prescriptions will be such that distance vision, if it's a problem, will be corrected. The second of the two prescriptions will enhance near distance.
• There are two basic types of Blepharitis: Seborrheic Blepharitis and Staph Blepharitis. The most notable symptom of either type is inflammation on and around the eyelids that can be accompanied by irritation and painful itching. In some cases, tiny ulcers develop along the eyelid margins which are the areas that touch one another once the eyelid closes.
• Whether or not buying eyeglasses online is less expensive isn't easy to answer. You have to spend time comparing prices to see if and where there are deals. With so many eyeglass and discount chains offering low prices on eyeglasses, most outlets, whether they're online-based or physical locations claim to offer the lowest prices. When you shop on the Internet, pay attention to shipping and handling charges as that's where your order total can really add up.
• Over time the eye's lens, which is transparent in a healthy eye, starts to become cloudy or opaque. As individuals age, protein levels in the eye begin to decrease which is why there is no way to effectively prevent cataract from developing. Other factors can cause cataract such as head injury and certain diseases, but their appearance is primarily due to age.
• As for skin tones, a person's skin is considered either cool-toned or warm-toned. If your skin has a pink or blue undertone, it's considered cool. Black, pink, magenta, pinkish-browns, slate, green, blue and dark tortoise patterns look good against cool skin tones. To complement warm skin, stick with eyeglass frame colors in light brown or orange tones such as khaki, camel, off-white, light-patterned tortoise shell, gold and coppers, coral/orange/peach and if you're bold, fire engine red!
• Are you older, younger or somewhere in between? Do you consider yourself to be trendy or conservative? Do you have a career or are you a student? What is your career or your area of study? Are you driven by name brands or do names not impress you? Do you look at eyeglasses as a fashion accessory or a necessary evil?
• The pigments inside each of the 3 cone cells react and respond differently as each absorbs light. Each pigment processes a different wavelength: short, medium and long. In a normal eye, this interaction and overlap between the cones, pigments and the amount of light each absorbs as the eye processes various images is what makes it possible to create the wide spectrum of color that most individuals are able to view.
• Even though you may not need them to correct your vision, if you want colored contact lenses you will have to visit an eye doctor to obtain a prescription. A prescription for contacts that doesn't include vision correction is called a plano prescription. This type of prescription measures the width and the curvature of the eye and will insure that the contact lenses fit properly. If they don't fit right you'll know in a moment because the pain will be persistent and irritating.
• The environment in which the computer work is taking place can be adding to the problems associated with Computer Vision Syndrome. Inadequate lighting, glare from windows, fluorescent lighting, sitting too close or too far away from the computer monitor and the manner in which the contents are being displayed on the monitor can all aggravate this syndrome.
• The infective form of Conjunctivitis, if it's caused by bacteria, is highly contagious with the hands being the primary vehicle for transmission. Conjunctivitis that results from an allergic reaction is typically a seasonal condition as are most allergies.
• More often than not, contact lens maintenance involves using one of the commercially-available multi-purpose solutions that take care of cleaning, disinfecting, rinsing and storage. After removing a contact lens, with hands that have first been washed using non-moisturizing soap, shoot the lens with a steady stream of the multi-purpose solution for a minimum of 20-seconds (or as directed), making sure that both sides of the lens are sprayed. Some solutions require that the contacts be rubbed in the palm of the hand using a clean fingertip to help loosen dirt, protein, cosmetics and other debris. Be sure to rinse each lens as directed as this is an important step in helping rid the lens of foreign matter.
• Kids who participate in sports find that wearing contact lenses is much easier than dealing with the hassle involved in wearing eyeglasses. Eyeglasses and sports aren't always a good match. They break more frequently and replacing children's eyeglasses isn't cheap!
• The development of toric contact lenses opened up a whole new world of vision for people with astigmatism. Toric contact lenses don't look any different than other soft or rigid gas permeable contact lenses, but in fact they are very different. The lenses consist of a number of different curvatures in various meridians or sections on the lens. Since astigmatism is a problem involving unbalanced meridian sections (due to the odd shape of the cornea) bringing the meridian sections back into balance is what helps produce clear vision.
• Extended wear contact lenses are perfect for busy people because they require minimal maintenance. They're also a good choice for individuals who work odd hours and double shifts such as doctors and firefighters. Extended wear disposable lenses are the most convenient because they're simply thrown away after they're removed.
• Results are both immediate and guaranteed. The moment you insert the contact lenses, vision is better and if it's not or if the contact lenses feel uncomfortable, then you've somehow ended up with an incorrect prescription, something that's easy to remedy.
• Here's a brief 2-part summary:
• Multifocal lenses are yesterday's bifocals and trifocals. As the name implies, multifocals have multiple focusing abilities and are commonly prescribed for activities such as reading and computer work. These lenses still have the telltale lines or curves that delineate the different prescriptions which is why more people are making the switch to progressive lenses. Bifocals offer near vision and distance vision correction, while trifocals include near, far and intermediate correction. Multifocal lenses are often prescribed when needed for specific job functions. As such, they're not generally designed to be worn daily - only when performing the specific task for which they were designed.
• The production of tears is an amazingly complex process. A tear actually consists of 3 separate layers and each layer has a purpose. There is a mucous layer, which coats the eye and acts somewhat like an adhesive. In the middle of a tear is an aqueous layer and it's responsible for delivering nutrients and oxygen to the cornea. Consisting primarily of water, this layer also has a bit of salt, which is why tears taste salty. The outer layer of the tear, the lipid, is oily and its job is to seal in the moisture so it does not evaporate. Tiny glands surrounding the eyes produce the ingredients needed for the various layers of tear, and excess tear fluids drain into tiny ducts.
• Metal has become a popular choice in eyeglass frame material. Everything from stainless steel to aluminum is used and these materials lend a contemporary look to eyeglass frames.
• What has come to be known as floaters and spots are particles of protein that break apart and float around the clear, gel-like fluid within the eyes. Because they break apart, no two floaters or spots are like in shape or size. They can have ragged edges, they can appear as tiny threads or cobwebs, they can appear as black or white flecks, and they sometimes appear as flashes of light.
• Another benefit of gas permeable contact lenses is that even though the plastic is more durable, which makes handling the lenses easier and less prone to damage, oxygen is still able to flow through, helping to keep eyes from becoming dry or irritated. The high gas permeability is also what makes these materials perfect for use in extended wear contact lenses. Eyes can breathe better, and the lens design ensures that tiny bits of bacteria and other particles can be flushed from the eye rather than trapped on the eye.
• This eye disease is a major cause of blindness because once the optic nerve has been damaged there is no known treatment capable of repairing it. A build-up of pressure in the eye generally triggers Glaucoma. In order to focus light and deliver a sharp image to the retina, the pressure inside the eye must always be maintained which enables the eye to maintain its shape.
• Early hard contact lenses were made out of polymethyl methacrylate or PMMA, also known as Lucite. This material was very uncomfortable but it did allow vision correction without any distortion. It took people a long time to get used to wearing hard contact lenses and they also required a considerable amount of maintenance.
• LASIK is the acronym for laser in-situ keratomy, eye surgery involving use of a powerful laser called an Excimer. The Excimer has been designed especially for working in the delicate eye area. The laser works quickly to reshape a person's cornea, which generally is all that is needed to correct myopia (known also as nearsightedness), hyperopia (farsightedness) and astigmatisms.
• There are two basic types of surgery: Standard LASIK and Custom LASIK. With either type, the preparation work and post-operative procedures are similar. The difference between the procedures involves the customization of the laser.
• Age has a lot to do with the eye's diminished capacity, but free radicals do much harm to the eyes as well. They can cause damage to the retina, located at the back of the eye. They can also interfere with the lens. Specifically free radicals can prevent the lens' ability to deliver light to the retina. When the light cannot focus properly, the retina cannot produce a clear image to send to the brain.
• Prosthetic contact lenses are perfect for people who have suffered an eye injury that has caused the eye to become somehow disfigured. They're also worn by individuals who have lived with an eye defect since birth. Such injuries and defects can leave the eye looking abnormal. For example, sometimes there is one big black circle where normally there would be a dark pupil surrounded by an eye color. A condition known as albinism might result in one eye being lighter in color than the other. The pupils might for some reason be misshapen or a person may have a deficiency in his or her color vision.
• When the cornea gets sufficient oxygen, the corneal epithelium is more likely to remain intact and that's necessary for ensuring clear and acute vision. When the epithelium breaks down, microbial keratitis may become an issue. These new lenses, because of their low water content, are also effective at keeping bacteria from adhering to the lens surface. That greatly reduces the likelihood of a microbial infection.
• It's not necessary to understand all the different makes and models of contact lenses. That's more the responsibility of vision specialists since they're the ones responsible for making the final determination based on their training, knowledge and past experience.
• Types of color deficiency
• An Excimer laser is a tool that was approved for the treatment of nearsightedness ranging in severity from mild to moderate. Use of the Excimer laser is complicated and it's important to work with ophthalmologists who are both trained in the surgical procedure and who have demonstrated the ability to properly operate and calibrate this precision instrument.
• Benefits of Epi-LASIK laser eye surgery
• For adults without eye trouble, eyes should be examined one time between the ages of 20-29, two times during the next 10 years, 2-4 times during the next 10 years and after age 65, eyes should be examined once every 1-2 years. People wearing corrective lenses should have their eyes examined yearly. Those with eye disorders should work out an examination schedule with their eye doctors.
• Benefits of LASEK laser eye surgery
• Are you having trouble seeing obstacles below you like steps and curbs or around you such as walls or furniture?
• But what happens when that invisible feeling starts becoming more noticeable? What happens when it feels as though there is indescribable pressure on one of your eyes? Or worse, what happens when you feel sharp, gritty or localized pain in your eye? More often than not, the culprit is a piece of dirt or other type of debris that somehow has become lodged between the inside surface of your contact lens and the surface of your eye.
• With prescription in hand, an individual can purchase contact lenses anywhere he or she chooses. That's an important point because by law, an eye doctor is required to give patients copies of their prescriptions upon request.

• Whether to wear contact lenses or not is a big decision and it's one that should be well thought out. This type of cosmetic enhancement, while beneficial in most cases, can lead to the onset of serious eye and vision trouble if maintenance guidelines are not strictly adhered to. It's not that contact lenses require a considerable or complicated amount of maintenance, but ensuring that the lenses are properly cleaned and stored does take a few minutes, every single time the lenses are worn.

The cornea's job is to bend rays of light that enter the eye so that these light rays can be better focused on the lens enabling the retina to produce a clear image.
  When the cornea has a more oval shape, like that of a football, light cannot focus properly
