Short Sightedness (Myopia)
Short-sightedness is a very common eye condition that causes distant objects to appear blurred, while close objects can be seen clearly. Myopia is the medical term for short-sightedness.
The symptoms of short-sightedness often start around puberty and get gradually worse until the eye is fully grown. Therefore it’s important to have regular eye examinations.
If you notice that distant objects seem to be fuzzy or your child is struggling to see things in the distance, such as the blackboard at school, you should arrange for a sight test.
Long Sightedness (Hypermetropia)
Long-sightedness, also known as hypermetropia, affects a person’s ability to see objects close to them.
If you are long-sighted, you will usually be able to see distant objects clearly, but nearby objects will be out of focus. Your eyes may also tire easily.
There are various causes of long-sightedness including age, genetics and certain underlying medical conditions, such as diabetes.
Children are usually born long-sighted. The problem usually corrects itself as the child’s eyes develop. However, it is important for children to have regular eyes tests because long-sightedness that does not correct itself can lead to other eye-related problems.
Adults can also develop long-sightedness, which often becomes more noticeable after the age of 40. Age-related long-sightedness is known as presbyopia.
Astigmatism is a common and usually minor condition of the eye that causes blurred or distorted vision. It occurs when the cornea or lens is not a perfectly curved shape. Most people who wear glasses have astigmatism.
If left untreated, astigmatism can also cause headaches, eye strain and fatigue (tiredness) – particularly after doing tasks that involve focusing on something for a long period of time, such as reading or using a computer.
