The most common problem that people have with their eyesight is myopia, which is also commonly known as near-sightedness. When you are near sighted, you will normally have trouble seeing objects that are a distance away from you such as reading road signs or seeing objects clearly. However, you won’t have difficulty in reading, using a computer or any other tasks that are close-up. Here, we are guiding you through what the commonly thought causes of myopia are and what you can do to correct it.

What Causes Myopia and What Are the Symptoms?

Myopia happens if your eyeball is too long as this affects the focusing power of the cornea and your eye lens. When light rays come through your work, instead of focusing directly on the retina surface, they instead focus at a point in front of your retina. Nearsightedness causes can also be your cornea or lens being too curved for your eyeball length and it is sometimes a combination of all these factors. It tends to begin in childhood and it is also normally down to your genetics whether or not you are near sighted as those with parents who have myopia tend to have a higher chance and getting it too. For most people, once you reach early adulthood It will stabilize, however, this is not always the case and for some it continues to progress with age.

Most people who have myopia will know quickly that this is what they are suffering from as the main symptom is having to strain your eyes to see clearly objects that are far away. You may also experience eye strain and headaches. If you are experiencing any of these symptoms, it is important you visit an optician. 

How to Treat Myopia

There are a few different ways in which you can correct near-sightedness. When you suffer from myopia, your prescription will have a minus sign in front of it and the higher this number is, the more near-sighted you are. Depending on how bad your myopia is, you may only need to wear glasses or contact lenses when you are watching a film or driving for example. However, some people may be required to wear their glasses or contact lenses all the time.

For most people, simply getting a pair of glasses will be enough to combat myopia. If you are near-sighted, there are a range of different lenses that you can pick and choose from to suit your eyes and your lifestyle. This includes high-index lenses which are thinner and lighter than normal glass or photochromic lenses where the glass will transition to a darker shade when it comes into contact with sunlight. This will protect your eyes from UV rays and is normally more convenient than having a separate pair of prescription sunglasses.

Contact lenses are another popular way for people to combat myopia. Contact lenses provide you with the freedom of not having to wear your glasses as often and most people find them to be a great option. These work by altering the way in which the light refract. It corrects the refractive error and gives you clear vision. This works the same for both glasses and contact lenses.

For most people, they will opt for glasses first and then use contact lenses at a later stage.

Finally, another popular way to control myopia, and the most effective if you are looking for a more permanent solution, is laser refractive surgery, also commonly known as laser eye surgery or LASIK. This is one of the most common surgeries in the world and it is incredibly popular due to its very high success rate as over 95% of those who have it are satisfied with the outcome. Laser eye surgery will physically reshape your cornea and in most cases it will completely eliminate the refractive error.

Controlling Myopia

As more and more people suffer from myopia, there is now more research than ever before to find ways in which to control this progression in childhood. There are many different techniques that are currently being trialled. This include fitting children with progressive lenses, bifocals and gas permeable contact lenses. Corneal reshaping surgery is also becoming extremely popular and this is commonly known as orthokeratology. This uses specialised corrective lens prescription and this is a strategy that aims to reduce the progression of myopia. However, while myopia control is on the rise, it has only proven so far to eb effective in children and there is still a lot more work that needs to be done in this area.
