Common Eye Conditions
Most people donâ€™t have a perfectly shaped cornea. However, when the curve is pronounced, your vision may be blurred and this is known as astigmatism. This is very common and is not a disease.
Short-sightedness is a common eye condition that causes distant objects to appear blurred, while close objects can be seen clearly. The medical term for shortsightedness is myopia. Itâ€™s thought to affect up to one in three people in the UK and is becoming more common. If distant objects appear fuzzy to you or if your child is finding it difficult to see things in the distance, such as the blackboard at school, youshould make an appointment for an eye examination. Children up to the age of 16 (or 19 if in full time education) are entitled to an eye examination free of charge.
Short-sightedness is a refractive eye condition. Refractive eye conditions occur when problems with the eyeâ€™s structure affect how light enters the eye. Light doesnâ€™t reach the light-sensitive tissue (retina) at the back of the eye, instead the light rays focus in front of the retina, resulting in distant objects appearing blurred.
Long-sightedness, also known as hyperopia, affects a personâ€™s ability to see objects close to them. Vision problems such as long-sightedness are often referred to as refractive errors.
There are various causes of long-sightedness including age, genetics and certain underlying medical conditions, such as diabetes.
