How does blurry vision make you feel?
Why to suffer when a visit to your eye doctor can set things right by way of comfortably-fitting and good-looking eyewear…or a pair of invisible contact lenses!
Sight test and glasses could improve the lives of people with poor vision
A simple sight test and eyeglasses or contact lenses could make a dramatic difference to the lives of scores of people who are suffering from poor vision. Children fail at school, adults are unable to work and families are pushed into poverty as a result of uncorrected visual impairment.
To mark World Sight Day, World Health Organization (WHO) released new global estimates which reveal that million of people around the world have uncorrected refractive errors (more commonly known as near-sightedness, far-sightedness and astigmatism). Refractive errors can be easily diagnosed, measured and corrected with eyeglasses or contact lenses, yet millions of people in low and middle income countries do not have access to these basic services.
Without appropriate optical correction, millions of children are losing educational opportunities and adults are excluded from productive working lives, with severe economic and social consequences. Individuals and families are frequently pushed into a cycle of deepening poverty because of their inability to see well. Scores of children (age 5 to 15) and working-age adults (age 16 to 49) are affected globally. Majority of people with uncorrected refractive errors live in low and middle income countries.
''Correction of refractive errors is a simple and cost-effective intervention in eye care,'' said Dr Serge Resnikoff, Coordinator of WHO's Chronic Disease Prevention and Management unit. ''Now that we know the extent of the problem of uncorrected refractive errors, especially in low and middle income countries, we must re-double our efforts to ensure that every person who needs help is able to receive it.''
Refractive errors occur when the eye is not able to correctly focus images on the retina. The result is blurred vision, which is sometimes so severe that it creates functional blindness for affected individuals. The three most common refractive errors are:
Myopia (nearsightedness) -- this is difficulty in seeing distant objects clearly.
Hyperopia also known as Hypermetropia (farsightedness) -- this is difficulty is seeing close objects clearly.
Astigmatism -- This is distorted vision resulting from an irregularly curved cornea. more
