Short Sight (Myopia)

by | Feb 19, 2014 | Health & Your Eyes | 0 comments


Myopia occurs when light is focused in front of the retina. It occurs because either the eyeball is too long, or because the cornea is too curved. Despite maximum flattening of the lens, the eye is not able to focus the light rays further back, and on to the retina.

People with short sight are not able to see distant objects clearly.

What are the symptoms?

The main symptom is a difficulty with distance vision. The earlier myopia starts, the more severe it is likely to become. By the time early adulthood is reached, the level of myopia has usually reached its peak and stabilises.

Some children do not realise at first that their vision is not as good as it should be. They may be able to read books and do close work well. However, seeing distant objects such as the board at school may become difficult. They may think this is normal and not tell anyone. Schoolwork may suffer for a while before the condition is identified and treatment provided.

If you suspect your child has problems with his or her sight, you should arrange for an eyesight test. Sight tests are free for children.

What is the treatment for short-sightedness?                                      


The simplest, cheapest and safest way to correct short-sightedness is with glasses. Concave prescription lenses (called minus lenses) are used to bend light rays slightly outwards. The light rays then have a greater angle to bend back to focus when travelling through the cornea and lens. As a result, the light rays focus further back – on the retina. We have a large choice of glasses frames available, to suit all budgets.

Contact lenses

These do the same job as glasses. Many different types of contact lenses are available. Contact lenses can be daily disposable, extended wear, monthly disposable, or non-disposable.  During a contact lens trail we will advise which type is most suitable for your eyes and your short sight prescription.


Surgery is an option for some people to cure their short sight. Generally, these operations are not available on the NHS, and so are a private option.
