Alarm clock rangs, i opened my eyes & turned him off to start my new challenging day . I swing my legs out of the bed and feel for my guide dog , Sacha . I am Suzie, 22 years old. I have been blind since birth, so I am used to adapt with the situation. All my friends have jobs and they will graduate from Uni next year. I don’t know what the future holds for me. I sure can dream. Life is a challenge when you’re blind. People think because your different, they need to treat you differently. They all feel sorry for me. They give attention and say things like “Oh, you poor thing”, and “Here darling, let me help you”. But I’m very independent and there is no need to help me. I get along fine. I can do things on my own, well almost.
Street crossing can be a significant challenge for visually impaired people, limiting their mobility especially in urban environments. To date, there are few solutions for this significant problem. Current approaches for guiding blind pedestrians in crosswalks have mainly focused on detection of crosswalks and crosswalk signals. Few studies have taken into consideration the mobility of a visually impaired person while street crossing . There are currently more than 285 million visually impaired people in the world, a number that is expected to triple in the next 30 years. According to the World Health Organization, around 80% of visual impairment is avoidable, which pinpoints the importance of raising awareness about the subject and the methodical examination of our sight.
Most common causes of blindness worldwide in 2010 were:
Cataracts ,Glaucoma ,Age-related macular degeneration ,Corneal opacification ,Childhood blindness ,Refractive errors ,Trachoma ,Diabetic retinopathy
Childhood blindness can be caused by conditions related to pregnancy, such as congenital rubella syndrome and retinopathy of prematurity. Central corneal ulceration is also a significant cause of monocular blindness worldwide, accounting for an estimated 850,000 cases of corneal blindness every year in the Indian subcontinent alone. As a result, corneal scarring from all causes is now the fourth greatest cause of global blindness.
People must be examined by doctor qualified to evaluate visual functioning of a compromised visual system effectively.
From the side off epidemiology , looking by age Visual impairment is unequally distributed across age groups. More than 82% of all people who are blind are 50 years of age and older, although they represent only 19% of the world’s population. Due to the expected number of years lived in blindness (blind years), childhood blindness remains a significant problem, with an estimated 1.4 million blind children below age 15. while by gender studies indicate that in every region of the world, and at all ages, females have a significantly higher risk of being visually impaired than males. Also , visual impairment is not distributed uniformly throughout the world. More than 90% of the world’s visually impaired live in developing countries.
At the end , people think they should treat differently blind person , but in reality they need to treat them respectfully .
