Research has shown that adding certain foods to your diet can improve your eyesight, reverse the signs of optical ageing and help keep our vision and eye health. Optimal health of our vision is directly related to the health of the individual parts of the eye. Healthy eating contributes immensely to maintaining good vision for life. Consuming certain foods will help to promote ocular nutrition and good eye health. There are nutritional steps that you can take to protect your eyes for the future and help to improve your overall eyesight and ocular health.

Eat your greens, and the some!
A recent study found that eyes containing higher amounts of lutien were up to 80 per cent less likely to suffer from macular degeneration. Lutien forms pigment in the macula, which helps to protect the eyes. Lutein is not generated naturally by the body, so adding dark leafy greens like collard greens, kale and spinach to your diet will ensure you are getting enough to maintain your macular eye health.

Carrots really can help you see in the dark!
It is no longer a myth that crunching on carrots will help you to see better. This bright vegetable contains an essential nutrient, carotene, which our livers turn into Vitamin A. Vitamin A helps to protect the eyes because it absorbs light energy that enters the eye. This results in eyes that are more sensitive in dim light, which can improve your night vision. Good sources of carotene can be found in bright and crunchy vegetables or fruits like carrots, mangoes and cabbage or in other food sources like cod liver oil, milk and eggs.

Blueberries are a magical fruit!
Eating blueberries will not only help reduce eye fatigue but they also contribute to boosting your night vision. There is anecdotal evidence from pilots in World War Two that show improved night vision after eating blueberries. The magical ingredient that makes blueberries to nutritious to the yes is a group of compounds called anthocyanosides. The compounds attach to an area in the retina that is directly responsible for adjusting the eyes for night vision. Blueberries are rich in flavour, nutrients and good antioxidants that can help your body resist damages to cells and tissues in the eyes.

So, take your mother’s advice that carrots can help you see in the dark, and eat all your veggies. Not only will it bring flavour and variety to your meals, but it will go a long way in helping you to maintain good eye health and improve your vision.

Hundreds of charities and eye foundations worldwide are dedicated to promote eye health and help people find curative treatments and surgeries for their sight-loss and eye health problems. If you are close to someone who is facing eye disease or a serious eye condition, you will appreciate the significance of the charitable work these organisations do in raising awareness and funds toward research, advancements in treatment and eye health care and support.

The Sydney Eye Foundation, formed in 1981, is one such organisation that is dedicated to raising money for updating its sophisticated opthalmologic equipment, expanding its research and healthcare facilities, enhancing its rehabilitation services, increasing its post-graduate training and in performing critical research into the prevention of blindness and serious eye diseases.

Blindness and vision impairment is a major public health issue all around the world. In fact, there is an estimated 285 million people who are blind or are facing serious vision impairment. What is most alarming about these numbers is that while some causes of vision impairment are not preventable, approximately 80 percent of all vision loss is preventable. Taking care of your eye health may not entirely prevent vision damage, but it will reduce the risk of developing problems and will help promote overall health.

In medical terms, blindness is considered a complete or partial vision loss that cannot be corrected through the use of glasses or contact lenses. There are many health conditions that can lead to blindness, but luckily there are also many ways that you can help minimise the risk of developing eye diseases and prevent blindness. Some of these include keeping your blood sugars at healthy levels, getting your eyes checked regularly and ensuring that your blood pressure is kept in check so as to prevent blood vessels in the eyes from bursting. In addition, adopting a healthy lifestyle will go a long way in maintaining your eye health through diet rich in nutrients and antioxidants. If you have concerns about your eye health, talk to your health care provider or an eye care professional.

Australia has a long and rich history of advancing the field of eye health and preventative eye diseases. As a pioneer in eye health, the Sydney Eye Foundation has continued to contribute immensely to this field and face the challenge of preventing blindness through its significant research and advancement in opthamological technology and techniques in diagnosis and treatment.

The Eye Hospital, Sydney focuses on keeping people’s eye health and vision in tip top shape. The hospital, well known for its research and advanced micro-surgical techniques, offers surgeries to clients in a personal and caring environment. Their experienced and quality surgeons have performed thousands of procedures using the most modern and advanced equipment to date. Many of these opthalmological advancements were developed at this state of the art eye care facility, which has performed thousands of successful surgeries. Their health practitioners are qualified experts in eye care and have been trained to be sensitive to the stress involved in eye surgery or treatment.

The majority of eye surgeries are performed as a day procedure. Before undergoing surgery, patients will walk through a variety of clinical steps that will ensure the best possible preparation for their treatment. This includes attending regular appointments with your surgeon and surgical counsellors, taking pre-operative assessments, undergoing physical examinations and filing out consent forms.

On the day of surgery, you should always try to arrive at the eye hospital a little bit early with the expectation of a two to three hour stay. It is key to make prior arrangements for someone to drive you both to and from the hospital as you will not be in a condition to drive. It is also recommend that you this person waits for you at the hospital in case the surgeon needs to provide instructions after the procedure. It is imperative that you follow any directions given to you by your surgeon both prior to the surgery and after the surgical procedure has been performed.

With such a high quality and comprehensive program for surgical procedures along with its caring and sensitive team of health practitioners, your day surgery at the Eye Hospital, Sydney will be an exceptional one. The knowledgeable and friendly staff will go above and beyond to facilitate your surgery by first greeting you at the door and then preparing you for a surgery with their highly trained surgeons. The philosophy for care at the Sidney Eye Hospital is one that focuses on providing specialised treatment all within a setting that is pleasant and positive for everyone involved.

The eye care specialists at the Sydney Eye Hospital know that a majority of vision loss is preventable or treatable if detected at the early stages. Vision loss can affect people at any time in their lives and uncontrolled diabetes can cause a host of problems in the body including eye problems or loss of sight.

It is crucial that Australians who are diabetic make it a point to get their eyes checked regularly. The blood vessels in the eyes are the smallest in the entire body and are susceptible to many vascular problems. When someone has high blood sugars that are not kept within normal ranges, the vessels in the eyes can become damaged. High blood sugars can cause the eyes to swell, which changes the shape of the lens and affects the ability to see. This damage does not occur from one high sugar meal, but happens when blood sugar levels are not controlled over a period of months.

When your blood sugars are high there is extra glucose floating around in the blood. The extra glucose will bind itself to red blood cells and once bound will not detach from the cells until the red blood cell dies. This prevents the red blood cell from doing its job of carrying oxygen to any cells. Thus, it can take up to three months for all the affected red blood cells to die and be replaced with new ones before the eyes or other organs can begin the healing process and function more normally.

The three most common eye problems that are caused by diabetes issues are cataracts, glaucoma and retinopathy. Cataracts cause a clouding of the eye lens, which creates blurry vision. Cataracts occur happen to others in the population but people with diabetes then to get cataracts earlier and the disease progress at a speedier rate.

If you are diabetic it is very important that you seek treatment for visual problems and follow the directions recommended by your doctor at the Sydney Eye Hospital. Make sure that you get your eyes checked regularly and that you take care of your eyes.

Glaucoma is an eye disorder that is characterized by build-up of intraocular eye pressure; it is mainly defined as an eye disease that damages the optic nerve. The optic nerve is the main visual nerve that is located at the back of the eye it is responsible for transmitting visual information to the brain that is, it receives light which are generated nerve impulses from the retina and transmits them to the brain. The brain then interprets the electrical signals and we recognize them via our eyes as vision. Glaucoma is not always associated with intraocular eye pressure since some cases have been reported to have been caused by poor blood flow to the optic nerve.

Glaucoma symptoms occur when there is increased fluid pressure that is the aqueous humour which nourishes the eye. If it increases elevated eye pressure results hence the eye becomes hard and if not treated blindness may result. After cataract it is the second leading cause of blindness.

Glaucoma is diagnosed via use of a tonometer which measures the intraocular pressure; the other methods used include various technologies: scanning laser polarimetry, optical coherence tomography and confocal scanning laser ophthalmoscopy technologies that create baseline images and measure the optic nerve and the eyes internal structures.

Glaucoma treatment mainly depends on the extent of severity and it can be treated via glaucoma surgery, medications, lasers or eye drops which are used to lower the intraocular pressure and also to control glaucoma.

Glaucoma symptoms depend on the type of glaucoma an individual has that is there are two types of glaucoma; open angle and closed angle glaucoma. Open angle glaucoma is characterized with high intraocular pressure that leads to an individual developing tunnel vision which helps the patient to see objects that are straight ahead. It is not painful and no acute attacks occur, the signs involved are: visual field loss and changes of the optic nerve.

Closed angle Glaucoma symptoms appear suddenly and they are: eye pain that is severe, visual disturbance in low light environments, red eye, seeing halos around light, blurred vision, nausea and vomiting.

An eye doctor is a medical professional who provides eye services; this individual is a health care worker who offers eye care services. Eye doctors differ from those who have a post-secondary training to those with a level of education in doctorate. Their different types of eye doctors and they include the following: an optometrist who is an eye doctor of optometry. Optometrists are general eye doctors, who have passed via college training of four years in a college of optometry; they specialize in treatment and management of eye diseases and disorders.

Optometrists are not allowed to carry out surgery and also not to treat all types of eye diseases. They are trained to examine both the internal and external eye structures in order to detect diseases like glaucoma, cataract or retinal detachment. They are allowed to treat various vision conditions like; near-sightedness, astigmatism, farsightedness and presbyopia. They can also prescribe contact lenses, eye exercises, low vision aids, vision therapy, eye medications and eye glasses.

The other type of eye doctor is an ophthalmologist, they are eye surgeons who are doctors of medicine and have four year training in medical school. They are fully qualified medical doctors and surgeons who can carry out both extensive and intensive medical and surgical exams. They provide eye services such as: vision services like eye examinations, medical eye care for diseases like glaucoma or iritis, eye surgery for conditions like cataract or tumours, treatment of eye diseases that are related to other conditions like diabetes retinopathy or optic neuritis, preventive services on eye injuries or diseases and plastic surgery.

An optician is an eye doctor who works together with both ophthalmologists and optometrists in order to offer eye services but not to perform eye examinations. They have a two year training qualification and are certified by the state where they want to practice. They assist in patient care before or during and after eye examination, procedures and surgeries. Their main role is to evaluate lens prescriptions that are written by ophthalmologists or optometrists, taking facial measurements, dispensing or repairing lens or frames and ordering eye related products.

An ophthalmologist is an eye doctor who mainly specializes in both medical and surgical care of the eye and the visual system. Their field is under a branch of medicine known as ophthalmology which deals with the anatomy, physiology and diseases of the eye.
They are either medicine doctors or osteopathy doctors. In order for them to get certified to practice in their specific states they should have the following qualifications: four years training in health school, one year of internship, a three years residency and one to two years fellowship which is optional. Before they enter into a training college they must meet the entry criteria and also must perform extensive and intensive medical and surgical examinations.

Here are a few factors individuals should consider when choosing an ophthalmologist: qualifications- patients should ensure that the doctor has the required credentials and has been certified to perform eye treatment and procedures. They should have their licenses and certificates placed at an area that is visible to all; this will help patients select the appropriate doctor. Experience is the second factor to consider, mainly doctors with more experience are able to detect and diagnose eye diseases better since they have come into contact with more patients who have various eye diseases.

At Sydney Eye hospital you will meet certified ophthalmologists. The hospital’s team of eye specialists is highly trained and experienced. Here are the major services which an ophthalmologist at Sydney Eye Hospital will offer you. Diagnosis of eye infections, injuries and diseases; the ophthalmologist will diagnose the patient’s cornea for any internal infections/ injuries as well as the external region of the eye to establish the presence of any external eye diseases, including conjunctiva, droopy eyelids and sclera.

The diagnosis will be used by the specialist to determine the depth of the eye infection/ injury or eye disease. Afterwards a prognosis will be established to determine the nature of treatment to be used.

Depending on the nature of the eye disease, an ophthalmologist Sydney will prescribe the correct medication and eye ophthalmologic surgery if necessary. Some treatment options used in big eye foundations, such as the Sydney Eye Hospital includes: cryotherapy and laser therapy; while surgical procedures include: eye socket refurbishment; renovation of tear vessel malfunction; and eye abstraction.

Cataracts are eye diseases that are characterized by a cloud that mainly develops at the eyes crystalline lens or at the lens capsule; the lens is the portion that lies behind the iris and pupil. Cataract causes decrease in vision, it can be mild, moderate or severe this depends on the extent of the cloud. It can occur due to aging which is common but can also occur rapidly; since its development and visual change is gradual most people do not recognize it. It can either affect one eye which develops rapidly unlike both eyes which is more common in most cataract patients.

Their various types of cataract and they are classified according to the anatomical location in the lens, its cause and the degree of clouding. Sub-scapular cataract is the type that develops at the back of the eye lens, people who are prone to developing it are: diabetic patients, those with farsightedness, retinitis pigmentosa and patients taking steroids at high doses. The other type is the cortical cataract which develops at the lens cortex; it is characterized as a white wedge like opacity. Senile cataract occurs mainly in the elderly, it is an opacity which swells of the lens and leads to loss of transparency completely.

Cataracts are caused by various factors such as: effects of diseases like diabetes, hypertension or trauma, intra-uterine development disorders, eye injury, genetic factors, aging, genetic disorders, exposure to ultraviolet light and ionizing radiation. They have the following signs and symptoms: blurred vision, near-sightedness increases, loss of contrast sensitivity, vivid colour vision, double vision in one eye and increased glare like when looking at headlights. Some Cataracts like subscapular do not produce symptoms until they develop fully.

Cataracts are treated with two methods that is, either surgical or non-surgical treatments, surgical treatment mainly involve removal of the cataract, there are two types of surgery they are: extra- capsular cataract extraction and intra-capsular cataract extraction which are used to remove the cataract permanently. Non-surgical is via use of topical treatment that is use of eye drops which are used to reduce glare sensitivity and improve eye sight.

Macular degeneration is an eye condition that is age related and mainly affects adults and leads to loss of central vision this is due to the effect caused on the macula. Macula is the central part of the eyes retina that provides the eye with detailed central vision. The central vision is what individuals see directly in front of them and not at the side which is known as periphery vision. It is one of the leading causes of blindness or visual impairments in the elderly and makes reading and recognizing faces difficult. Other daily activities can be carried out easily since the peripheral vision is not affected.

There are two types of macular degeneration and they are: the dry form which results from the breakdown of the macula cells hence leading to the central vision being blurred. It does not cause blindness but deteriorates an individual’s central vision which is essential for reading or recognition purpose. This type is characterized by drusens which are multiple yellow white spots located at the back of the eye.

Wet form is the other type and it occurs when abnormal blood cells develop under the central part of the retina which leads to central vision distortion. This is due to the leaking of the blood vessels and the scaring of the retina, loss of vision is more rapid than in the dry form.
The main symptoms of this condition include: blurred vision that is decreased distance vision, blind spots due to loss of macular function, metamorphopsia whereby straight lines look bent and micropsia whereby objects appear smaller than in the other eye.

Macular degeneration can be treated according to the presented type, the dry form treatment is not yet found but antioxidants can be used to prevent damage of the retina. The wet form can be treated via the laser method which prevents vision loss during the early stages of the disease, the photodynamic therapy which involves use of both the drug verteporfin and laser method. Antioxidants can also be used to prevent damage of the retina by free radicals or unstable oxygen.
