Becoming an eye doctor is a challenging process since it involves long years of education, hence determination is a MUST requirement. An eye doctor is a person who provides eye care services. There are various eye doctors and they differ depending on their level of education. In order to be an eye doctor one has to make a decision on the type of eye specialist he or she wishes to pursue. The main types of eye health care specialists are: optometrists, opticians and ophthalmologists. They have the same goal, which is to provide the best eye care services. These services involve eye surgery, eye examination, selection and fitting of both eye glasses and eye lenses.

Here is a layout on how to be an eye doctor. Ophthalmologists are Medical Practitioners who have specialized in the visual system. They are fully certified to provide services of the entire visual system, which involves prescription of glasses to eye surgery procedures. In order to be a licensed ophthalmologist one is required to attend a medical school for a bachelor’s degree for four years and residency training in both medical and surgical eye care for four years. Qualified ophthalmologists can choose to specialize in a specific area such as neuro-ophthalmology.

Optometrists are referred to as doctors of optometry; they offer the following services: eye examination, diagnosing, treating and managing eye diseases and disorders. They can also offer pre and post-surgical eye care and can also prescribe vision aids, eye glasses and contact lenses. A qualified optometrist must have a degree from an optometry college after his undergraduate degree. Lastly, opticians are eye technicians and they are classified based on the following categories: dispensing opticians and manufacturing opticians. They have a two year technical degree and they are trained to read prescription written by ophthalmologist and optometrists. They dispense eye wears such as eye glasses. Addition, opticians repair and adjust eye glasses.

What is glaucoma? Glaucoma is an eye disease that affects the optic nerve hence causing a progressive and complete vision loss. The optic nerve is the main nerve of vision; it receives light from the retina and transmits it to the brain for interpretation as vision. This type of eye disorder develops progressively; it begins with the loss of the peripheral vision and then loss of the central vision. Due to its slow development process symptoms may go unnoticed hence the condition is termed as the silent vision killer. Glaucoma blocks the drainage system of the eyes clear fluid hence leading to fluid build up and increased eye pressure. Due to this the optic nerve deteriorates and if left untreated total blindness may result.

What is glaucoma and its various forms? Glaucoma is classified into two main types that is, the open and closed angle glaucoma. The closed angle glaucoma is also termed as acute angle closure glaucoma. It is presented with immediate pain and eye discomfort which ensures quick treatment hence prevention of vision loss. The open angle glaucoma is also referred to as chronic glaucoma. This form develops slowly and the individual may not notice since he or she may not feel any discomfort. This leads to vision loss hence eye doctors recommend regular check ups in order to avoid such occurrences.

Other types of glaucoma include: low tension glaucoma, prigmentary glaucoma, secondary glaucoma and congenital glaucoma.
What is glaucoma and its presented signs and symptoms? Glaucoma patients mainly present with the following signs and symptoms. Eye pain, nausea, vomiting, blurry vision and halos around light. Individuals who have this signs should seek medical attention. Treatment methods for glaucoma depend on the severity of the condition. These forms of treatment involve glaucoma surgery, medications such as eye drops and the laser treatment.

Macular degeneration is an eye disease that affects the macula and it is known to destroy the central vision system. It develops when part of the retina is dented causing progressive vision loss. This type of eye disease is known to be the leading cause of total blindness in Australia. It is classified into two major categories, and they are dry and wet Macular degeneration. This eye disorder occurs due to various factors such as aging, prolonged exposure to ultra violet rays, smoking, obesity, myopia, sleep apnea and certain medications such as drugs for osteoporosis.

Macular degeneration is categorized into two forms i.e. the dry and wet forms. The dry type is also known as the atrophic form, it occurs after the macula cells breakdown. During eye examination the condition is identified when yellow white spots known as dursens are seen around the retina. This condition is the most common and if it advances there will be changes in the nerves and sensory parts of the retina. The wet type is also referred to as exudative or neuro-vascular form.

Development of this condition leads to leaking of the blood vessels which scars the retina hence damaging the eyes central vision. This eye problem is more rapid than the dry type therefore vision loss may occur more rapidly.

Patients with Macular degeneration present themselves with the following symptoms. Blurred vision, objects appearing to be small, viewing straight lines as irregular lines, decreased central vision and blind spots. In order to avoid total blindness patients are advised to consult eye doctors for regular check-ups and if the above symptoms arise he or she should seek medical treatment. Macular degeneration can be treated via use of antioxidants that prevent unstable oxygen that damages the retina. Laser treatment reduces vision loss during the early stages of the condition. Photodynamic therapy; that involves the use of the drug verteporfin; the drug is administered intravenously to close the leaking blood vessels.

What causes blindness is an important topic to discuss as far as Australians are concerned. Many people in Australia tend to ignore various factors that may lead to complete loss of vision. Some of the leading causes of blindness include: diabetes, traumatic injuries, herpes simplex virus, and eye diseases such as glaucoma, retinitis pigmentosa, cataracts and macular degeneration. Blindness may affect one eye or both eyes and may not cause total darkness since some people who are blind can see shadows and some beams of light.

What causes blindness in most people begins with an eye disease that advances into complete vision loss. Cataract is a clouding of the eye lens that makes an individual’s vision to be blurred and it develops a problem of seeing through glare. It is known to be the leading cause of blindness all over the world if left untreated. Individuals who have the following symptoms (bury vision, glare, and double vision) are unable to see well at night as well as perceive faded colours; ideally, such people are advised to seek treatment. Glaucoma is an eye problem that deteriorates the optic nerve, this causes fluid build up and increased eye pressure. It leads to gradual loss of the peripheral vision. It is also a leading cause of blindness and immediate treatment after diagnoses is important.

What causes blindness in many adults is an eye condition known as macula degeneration. This eye disorder is mainly associated with aging and it damages the macula. Macula deterioration leads to loss of the central vision system and blurred vision arises. Diabetic retinopathy is an eye disease that is caused by diabetes. It mainly affects blood vessels that nourish the retina and it causes leaking hence vision loss. Retinitis pigmentosa is an eye problem that begins during childhood and the infected person becomes blind at adulthood. Individuals with this eye disease have a problem of perceiving objects at night.

What is macula? The macula is located near the central portion of the human eye retina that is described as a yellowish oval shaped spot that is highly pigmented. The macula enables the eye to view detailed central vision that is sharp, to perceive colours and to carry out tasks like reading that is tasks that require central vision.

The macula consists of two ganglion cell layers and at the centre it comprises of the fovea. The fovea is a pit made up of cone cells and has no rods; the fovea’s function is to ensure that the eye provides a central vision of a high resolution. The fovea is also responsible for individuals colour perception ability. The macula is also made up of the peri-fovea and para-fovea.

What is macula and how is it adopted to its functions? The macula comprises of light sensitive photoreceptors that are densely packed together. This enables the macula to be in control of the central vision and the ability to do tasks like reading, distinguishing faces or details and driving. Having numerous cones in the macula enables the eye to have a sharp vision especially in bright light. It is yellow in colour since it is made up of lutein and zeaxanthin. Due to this it is able to absorb excess ultraviolet light and it also blocks entry of excess sun light.

What is macula and its clinical significance? If the macula is tampered with various eye diseases can develop. Macular degeneration can occur if the macula breaks down. This condition leads to the decreased ability of the eye to see clearly due to either partial or complete vision loss. Macula degeneration can also develop due to aging hence the elderly are at a higher risk. Destruction of the macula can also lead to formation of macula holes which are caused by trauma and if severe the entire macula can be damaged.

What is Amblyopia? Amblyopia is an eye disorder of the visual system also referred to as the lazy eye. Amblyopia is described as vision deficiency that leads to loss of the eyes’ ability to see details in objects. The affected eye will look physically normal but it does not function normally since the brain is coordinating with the other eye.

This condition develops when the nerve pathway to the brain of one eye does not fully develop during childhood. The affected or abnormal eye tends to send blurred or incorrect images to the brain. When this occurs the brain becomes confused hence it learns how to ignore images from the abnormal eye. The lazy eye may also develop when one eye has a better focus than the other that is one eye might have a lot of astigmatism or it may also be too near-sighted or farsighted.

What is Amblyopia most common cause? Strabismus is the common cause of the lazy eye. It is mainly an imbalance in the positioning of both eyes. It is characterized as an ocular misalignment that leads to one eye either turning inward that is esotropia or turning outwards that is exotropia. This deteriorates the eyes ability to focus on an image which may lead to development of double vision. Other causes of Amblyopia are certain conditions such as cataracts, blood or material at the back of the eye which block entry of light.

Its symptoms and forms of treatment include: Signs and symptoms presented by patients with this vision problem are such as poor vision in one eye, inability to perceive depth, eyes turning in or out and lastly both eyes working together. It can be treated by making the individual’s brain to use the weaker eye. This is achieved via correcting eye problems that cause Amblyopia such as removal of a cataract and then placing a patch on the normal eye and also use of atropine drops.

Eye exercises are part of vision therapies that are meant to improve vision skills such as eye focusing, moving and coordination. Exercising the eyes will enable them to be healthy in order for the visual system to work normally. Working out the eyes will improve the functionality of the eye muscles hence a good vision is obtained. These exercises are of different techniques and they have been proven to improve vision hence patients negating corrective lenses. If you wish to perform these techniques you can consult with an eye doctor or do some research in the internet.

Here are some of the best Eye exercises that you can opt to engage. Blinking is a simple technique that will help you keep your eyes fresh and able to focus on objects for long durations. By doing this exercise your eyes are able to discharge previous info and get ready to perceive new info. Moreover, you will be reducing eye strain and your eyes will be relaxed. Blinking is also a sign of good communication skills.

Individuals who blink after every three seconds are termed to be friendly unlike those who stare.

Zooming is a technique that requires you to follow the following steps. First sit in a comfortable position, stretch your arms and ensure that the thumb is in a hitchhike position. Focus on the thumb and bring it closer to your eyes. Focus until the thumb is about four inches away from your face. Move the thumb away until your arm is outstretched fully. Do this exercise for a few minutes each and every day. Palming is also a simple eye exercise that helps to relieve stress around the eye region and to relax them instead. This is done by leaning on a desk and resting your elbows on your knees then placing your hands over your eyes to cover them. This is useful during computer breaks.
In conclusion, Eye exercises will definitely make you feel relaxed.

What is a cataract? Cataract is a clouding condition that develops on the eye lens hence blocking the passage of sufficient light. This may increase the lens power by causing near-sightedness or may reduce the eye perception of colour blue. If left untreated the patient may become totally blind. There are various types of cataract that affect people in Australia every day and they are classified according to the anatomical location, cause and degree of the clouding.

They include: Sub-capsular cataract; this form develops at the back of the eye lens i.e. in the capsule. People who are at a higher risk of developing this type of cataract are diabetic patients and individuals taking high doses of steroids. The nuclear cataract is mainly associated with aging. It occurs at the central zone, basically in the nucleus of the eye lens. The next form is cortical cataract that occurs at the lens cortex. It develops at the periphery of the lens and later spreads to the centre of the lens. Individuals with this form of cataract have white wedge-like opacities at the affected region.

What is a cataract? This is a common question asked by many individuals since this type of eye diseases develops silently and may distort the entire vision system. Other potential factors leading to cataracts include: Aging, age related cataract occurs during the aging process when the lens protein begins to join together and form a clump. This leads to the growth of a cloud around the eye lens. The other causes include: exposure to ionizing radiation such as x-ray and ultraviolet rays, eye surgery, eye injury, disease like diabetes, consumption of medications such as corticosteroids, congenital infections like herpes simplex virus and genetic diseases like Down syndrome and myotonic dystrophy.

The above content should clearly help any Australian to understand and appreciate the need of eye check-ups in order to avoid any chances of contracting cataracts.

Their various eye disorders that affect the human visual system, they affect both adults and young people. Most eye problems are termed as the leading cause of partial and complete blindness. Cataract is an eye condition that is described with a clouding on the eye lens. This condition blocks the transmission of light to the retina where images are interpreted. This causes loss of vision, it has the following symptoms; swelling, pain, redness and tearing. Individuals who experience the above symptoms should seek medical treatment which involves cataract surgery.

Glaucoma is another common eye condition that develops gradually and damages the optic nerve of the eye. It involves increased eye pressure due to leaking of eye fluids. Glaucoma may arise due to eye injuries, eye infection, blocked blood vessels and inflammation. It can be treated via use of eye drops and surgery for permanent removal.
Conjunctivitis also known as the pink eye is an inflammation that affects the eyes conjunctiva. The conjunctiva is the tissue that lines the eyelids and covers the cornea.

This condition is presented with the following signs and symptoms; itchiness, tearing, production of a discharge, redness and an inflammation. It is treatable via use of various home remedies and medications like eye drops and ointments.

Other common eye disorders include those affecting the retina that is, retinal disorders. These disorders are such as retinal detachment, macular degeneration and diabetic retinopathy. Retinal detachment is an eye problem that separates the retina from its location which is at the back of the eye. Macular degeneration on the other hand affects the macula hence its development leads to loss of the central vision. It is classified into two that is the wet and dry macular degeneration. Diabetic retinopathy causes changes in the eyes blood vessels by affecting the retina.

To avoid developing eye disorders individuals should undergo regular eye check-ups.

What is conjunctivitis? Conjunctivitis is an eye disease that is also known as the pink eye. This eye problem mainly affects the conjunctiva which is a tissue that covers the sclera. It covers the white part of the eye and lines the inner part of the eyelid. Conjunctivitis can be caused by bacteria’s, other diseases, viruses and allergens. Conjunctivitis is classified into three major categories that are dependent on the cause of the problem.

Bacterial conjunctivitis is caused by bacteria’s such as those related to sexually transmitted diseases. This type may damage the entire visual system if left untreated. It can be treated via use of antibiotics like eye drops, pills and ointments. Viral conjunctivitis is caused by viruses such as the virus that causes common cold. It is contagious but runs for only a few days just like a cold. Individuals who develop this type should avoid contact with other people, avoid sharing items like towels and wash their hands regularly.

Allergic conjunctivis is an eye problem caused by various allergens like pollen or dust and irritants like chemicals. This type of conjunctivitis can be either seasonal such as pollen allergy or flare up that is through out like dust allergy. It can be treated through use of allergy medications such as anti-histamines.

What is conjunctivitis and its symptoms? Conjunctivitis symptoms are dependent on the cause. Viral conjunctivitis is presented with watery eyes, itchiness and light sensitivity. Bacterial conjunctivitis is described to have symptoms like a sticky discharge that is greenish-yellow in colour. This discharge makes the eyelids to stick on each other. Allergic conjunctivitis is presented with watery eyes, running nose, itchiness, swelling, light sensitivity and stuffiness. Conjunctivitis can be significantly prevented by maintaining proper hygiene as well as avoiding eye irritants through the day. In conclusion, routine eye check-ups are also essential as far as prevention of conjunctivitis is concerned.
