Nearsightedness and farsightedness are two of the most common eye refractive errors out there. These irregularities damage the eye's ability to focus light properly. For one to see clearly, light must be refracted through the cornea to focus on the retina located at the back of the eye. Blurred vision occurs when these light rays entering the eye fail to focus correctly on the retina.
A survey conducted across America to investigate the people’s most significant health fears found vision loss to be among the top four fears, even higher than the loss of speech and memory. Seeing this, people should then do all they can to keep their eyes healthy and prevent some common eye diseases.
Estimates suggest that more than 20 million Americans live with severe vision loss. Although it’s impossible to prevent every eye problem and disease, there are things that you can do to help keep your eyes healthy and in good condition, reducing your risk of experiencing vision loss in the future.
Vision doesn’t just happen; it develops over time. When we are born, our vision continues to develop and as we grow, our brains learn how to use our eyes to see in much the same way as it learns to use our legs to walk, or our mouth to talk. If we experience a vision problem that isn’t diagnosed and treated, our brain learns to accommodate them and find a way around them.
