Vision Impairment is defined as the reduction in vision, which cannot be corrected by the usage of prescribed glasses, contact lenses, medication, or even surgery. This may affect the metabolism and daily activities of the people. The symptoms with cataracts, glaucoma, head injury, and lack of nutrition are associated with vision impairment. Multiple sclerosis and other similar related nervous disorders, brain tumours are rare causes for the blindness. Preventions include regular eye exams and controlling of diabetes mellitus is very important in preserving the sight.

Eye twitching is usually caused by fatigue, stress, excessive amounts of tobacco, alcohol, caffeine and few other factors. But even doctors aren’t sure about the exact reason on what causes eye twitching.
Some kind of allergies, irritation and dry eyes are also linked to eye twitching. In some cases, eye twitching can present a symptom of a more serious and severe neurological disorder such as blepharospasm (also known as abnormal blinking or spasm of the eyelids) or amyotrophic lateral sclerosis (ALS) or more commonly known as Lou Gehrig’s disease.
Statistics show that in the US only more than 2000 cases develop every year, in mid to late adulthood blepharospasm is more likely to develop in women than in men. You should know that this condition if detected early is not serious. You might be more sensitive to light, get blurry vision and even your entire face can start twitching as the condition progresses.
There is no need to get worried if the twitch lasts for a few minutes, but if it last for more than an hour than you should consult a doctor.
If you experience any of the symptoms bellow we recommend that you see a doctor as soon as possible.
If the condition is more serious that your doctor will redirect you to a neurologist or other specialists. It is highly important that you get a detailed checkup to make sure there is no neurological disorder.

“It isn’t just particles in the air that can harm the eye. UV radiation due to ozone depletion is a cause of cataracts. According to the World Health Organization, 5 percent of the 18 million who have cataracts had their cataracts develop as a result of UV radiation. UVA light stimulates the production of oxygen-free radicals that are responsible for clouding the eye’s lens. UV radiation can also play a part in the development of age related macular degeneration.” We often think about protecting our skin, or respiratory system against environmental factors, like the sun or pollution. But, it’s time we think about protecting our eyes as well! Our eyes are extremely susceptible to the elements and our surroundings. Things like pollutants, toxins, and the weather all affect our eyes. How come? Well, the sclera, cornea, and the lens are exposed. We do have some protection in the form of eyelids, eyelashes, and tears but, air pollutants like second-hand smoke, unfortunately, cannot be stopped from entering the eye. Environmental factors can cause issues from dry eye syndrome to serious diseases like age-related macular degeneration.

Session 4: Optical Oncology is the study of cancer which deals with the treatment of cancerous conditions of the eye and its surrounding tissues. The cancers may occur in the eyelids, the tissues behind and around the eyeball, and even the eyeball itself. The cancer which involves the orbit is rare and the most common type in the adult eye is choroidal melanoma. A variety of tumours that exist in the eye tissues can include melanomas, metastasis, retinoblastoma, lymphoma, carcinoma and so on.
Ophthalmic Lens is a lens which corrects the vision in a person where the focal point in the eyes does not hit the retina. They come in a variety of forms including plastic and glass lenses worn in glasses, contact lenses placed in direct contact with the eye, and lens implants surgically inserted into the eye to correct visual impairments. Basic ophthalmic lenses correct for near- or farsightedness, where the focus point lies in front of or behind the retina. They curve to adjust the focal point and let light hit the retina precisely, allowing people to focus. Other lenses can have additional features. The earliest ophthalmic lens designs were glass.
Vision Rehabilitation is the method of treating and educating the visually disabled people to acquire a supreme and determined function, a sense of happiness and comfort, an independent feeling and optimum quality of life. Vision Rehabilitation is required by any condition, disease or injury results in functional limitation or dysfunction. It has the potential to prevent depression and emotional distress and improves the ability to perform the daily activities and the overall visual ability.
