A Refractive Error a cures when your Cornea or lens isn’t evenly, and smoothly curved, light rays aren't refracted properly, and you have this condition. In order for you to see, light must pass through the cornea at the front of your eye, through the pupil, and then be focused by the lens onto The Retina . The Retina sits at the back of the eye and converts incoming light into signals your brain can understand. When these structures are all in perfect alignment, you have crystal-clear, 20 20 Vision . When they are even slightly out of alignment, you will end up with Blurry Vision . This is called refractive error. Types of Refractive Error You can use state-of-the-art Advanced Custom Cornea Laser Eye Surgery to carefully reshape your cornea and correct refractive errors such as Myopia also known as Nearsightedness, Hyperopia also known as Farsigntedness and Astigmatism. Since these advanced techniques do not require that they cut a flap in the cornea, most patient...

An Eye Pterygium is an abnormal mass of tissue arising from the conjunctiva of the inner corner of the eye that obstructs vision by growing over the cornea. Causes of a Pterygium UV radiation (usually from sunlight) is the most common cause of a Pterygium. This explains why a Pterygium occurs with increasing frequency in climates approaching the equator. Other causes include continuous exposure to dry, dusty environments. People who spend significant time in water sports (surfing or fishing) are particularly susceptible to Pterygiums because of the intense exposure to UV that occurs in these environments. When UV rays continuously assault the eye, the conjunctiva may thicken in a process similar to callus formation on the skin. The sensitive structures of the outer eye often cannot comfortably tolerate this degenerative process, and irritation, redness, foreign body sensation, and ocular fatigue can result. Therefore, wearing UV-blocking eye wear may not be sufficient in pre...

It's an arguable position that nothing is ultimately more important than nutritional supplements for eye diseases , when it comes to eye health and diseases. Eye Health Supplements have long been a way to boost the body's immune system, give it the proper nutritional requirements if the diet is lacking, and promote the growth and reproduction of cell tissue, which is why Eye Supplements are often used for anti-aging purposes.

Free radicals are molecules that are missing an electron. This leaves them unstable and highly reactive, that is, they will react with just about any other molecule they find. They steal an electron from these molecules, damaging cells and cell membranes. They even have the power to damage your DNA. Your body creates these molecules as byproducts of immune processes. When bacteria, viruses and any other foreign substances enter your body, your immune system destroys them. This destruction results in free radicals . These molecules can also develop from the presence of heavy metals in the body. Radiation exposure also creates them. Sunlight, pollution, food contaminants, and especially smoking all provide or create even more of this. Superoxide is the most reactive of all free radical chemicals; it is a very toxic oxygen molecule. Your body uses superoxide dismutase (SOD), an antioxidant enzyme, to neutralize superoxide. This reduces the damage you incur from the millions o...

A high fat diet harms your sight by clogging up blood vessels in The Retina and the choroid, which can reduce the flow of oxygen and nutrients necessary for vision. Your body runs on glucose. Your body burns glucose to provide the energy you need to keep your body processes functioning. Calories are the measure of the amount of energy you get from glucose. Carbohydrates, fats and proteins are all used by the body to provide glucose when needed. Carbs and proteins both provide four calories per gram; fats provide nine calories per gram, more than twice as much. This means that every time you eat foods that are high in fat (dairy products, red meats, poultry, oils, margarine, and processed foods) , you are putting more than twice as many calories into your body. When your body has more calories than it needs at the moment, it stores the rest in fat tissues, even if it has to make more fat tissue. A high fat diet harms your sight, it produces the fat deposits that accumulate un...

The are Many Slow Moving, Chronic Eye Conditions. Retinal Detachment is Not One of Them Many eye conditions are slow moving, like cataracts, where changes in vision are gradual to the point your vision is greatly impaired. Surgery for cataracts is normally not done in a rush and can easily be planned in advanced. Retinal detachment is a different story. If you experience its symptoms you need to act fast. The retina of your eye is a layer of tissue lining the interior of your eye. It sends visual signals through your optic nerve to your brain. If the retina comes off, if not treated immediately, the detachment could result in permanent vision loss. Retinal detachment involves the retinal cells coming loose from the layer of blood vessels underneath them. Those blood vessels provide oxygen and nourishment needed to keep the retina healthy and functioning. The longer it goes untreated, the greater the chance of permanent vision loss. Retinal detachment can happen at any time but more...

Double Vision is a condition called diplopia, and can be very serious. As humans, vision is one of our most used senses, so when something goes wrong with it, for example when we wake up one morning and have Diplopia , it can be very frightening. If you do find that you have Diplopia for no apparent reason, you should always try to set up an appointment with your Eye Care Specialist or Eye Care Professional as soon as possible. To understand what causes double vision, you first have to understand how the eye works. It's an intricate system of hundreds of thousands of different processes that all take place simultaneously, similar to a large machine with multiple cogs and levers. If just one part is not functioning correctly, the end result is not what is expected. Again, this can be extremely frightening, especially when you've spent years getting the same results out of that machine. Simply put, this is the way the Visual Process works. First, light comes in throug...

Astigmatism In Children is an eye defect, which causes Blurry Vision due to the eye being unable to process or to clearly focus on a given object. This is because there is an irregularity in the Cornea or lens. There are two different types of astigmatism in children. Regular Astigmatism can come from an impurity in either the cornea or crystalline lens and can be simply fixed by a Toric Lens . Toric lenses have two layers; the second is slightly smaller than the first one. Toric Lenses for Astigmatism are typically shaped like a prolate spheroid or a toroidal; it is these shapes that help the eye conform to its should be state. The other type of astigmatism in children is called irregular. Irregular Astigmatism is caused by either having a corneal scar or some sort of scar in the crystalline lens, due to the nature of the damage; normal Eyeglasses can not correct the problem. To Protect Your Eyesight or to correct any problems, you will need to either use Prescription G...

It's not uncommon for a person to experience an eye infection and allergy at the same time, and it's actually pretty common for an allergy to develop into an infection if it's left untreated. Pink Eye is the common name for most eye infections that cause the eye to swell up and turn red. It's actually sort of an umbrella term used to describe these symptoms, and contrary to popular belief not all cases of pink eye are actually contagious. The term pink eye comes with a sort of stigma that it's easily transferred from one person to another, but that's actually only the case if the infection is caused by a bacteria or virus. Eye infection and allergy symptoms are often the same though, which is why someone with an Eye Allergy might easily confuse it with an infection. Allergic conjunctivitis is the actual term for an eye allergy, and the Eye Allergy Symptoms of that usually include swelling, redness, excess tearing, and Blurry Vision due to all the tears ...

A study, led by Dr. Daniel Martin, an ophthalmologist at the Cleveland Clinic’s Cole Eye Institute, has found that the cancer drug Avastin (bevacizumab) offers macular degeneration patients the same benefits as the drug Lucentis (ranibizumab), which was specifically formulated to treat the disease. “The results of our study show that Lucentis and Avastin are virtually identical, in terms of visual acuity achieved, when they’re given on the same dosing frequency,” Martin said in a press release. “For example, if you compare Lucentis given monthly versus Avastin given monthly, it’s virtually identical for visual acuity achieved in one year.” The big difference between these two drugs is in their cost. Avastin costs about $50 per treatment compared to $2,000 for Lucentis. The study’s complete findings were published in the New England Journal of Medicine . In 2018, National Health Service (NHS) England decided to pay for Avastin, in place of Lucentis for AMD. The drug manufacturers Ba...

Exercising protects your vision by getting the body moving. Moving your body leads to cardiovascular health. A strong cardiovascular system helps Protect Your Eyesight by enhancing the delivery of oxygen and nutrients to the eyes, and by improving the removal of waste products that develop in the eye. As mentioned in The Visual Process the highest concentration of oxygen in the body is found in the eyes. By exercising and helping your cardiovascular system do its job, you’ll be giving your eyes all the oxygen they need for disease-free vision. Oxygen is the fire that burns the fuel provided by nutrients. Without the nutrients your eyes needs, your vision can deteriorate. exercising protects your eyesight and will help ensure that your eyes get all the nutrients they need.

The gene that is responsible for the color pigments in the eye are carried through the male X chromosome, and as such most color blindness is found in men. In fact, nearly every case of color blindness is diagnosed in a male, and it's incredibly rare for a female to be born colorblind. While it's not exactly rare in men, it's not extremely prevalent either, with an estimated 10 out of every 100 men being born with some level of Color Blindness , or 10% of the male population. Some estimates have this number at 8%, but you can get a general idea of how often it shows up in the general population. In other words, if you know 30 people, chances are at least 3 of them are color blind in at least some way. The thing with Color Blindness is that sometimes it's hard to even tell that you have it, especially if the Symptoms of Color Blindness are extremely light. Out of that ...
