5 signs you may need glasses
We use our eyes pretty much every second of the day and our vision is arguably the most important of our five senses. Despite this, many thousands of Britons are going about their daily business without glasses when they really should be wearing them.
When vision deteriorates it tends to do so very slowly, meaning we are often unaware that is has happened. This is why it is crucially important to get your eyes checked regularly to make sure your vision is as good as you think it is.
This is especially important if you are a driver as you could be driving around illegally without knowing it. The law states that it is the driver’s responsibility to ensure that they meet the legal driving requirements.
On a more general level, you may be struggling to read your computer screen at work or straining to make sense of important documents.
Here are five signs that you may need glasses:
Squinting/screwing your eyes up
This is the single most likely sign that you need glasses and people tend to do it when they are trying to view distant objects. The reason squinting temporarily improves your vision is that by screwing your eyes up you are effectively reducing the size of the pupil in your eye. Your pupil is where the light enters your eye and a smaller pupil reduces the blurred vision.
Needing glasses is one of the most likely causes of headaches and they are likely to occur after you have being concentrating on a task for a long period of time – for example, working on the computer. Headaches that are caused by your eyes tend to be at the front of your head (frontal) and at the sides (temporal). The headache will normally manifest as a dull ache which can last for hours.
Holding books further away from you
If you find that you are holding books and other reading material further away from you, then you almost certainly need glasses for reading. We have a natural lens in our eye whose function is to focus on objects that are near to us. As we get older so this lens does not work as well and hence we start holding things further away from us. This unfortunately continues to deteriorate as we get older, meaning we need stronger and stronger glasses.
If you find you are struggling to judge distances, such as when you are parking a car, this may mean your eyes are not properly in focus. Stereopsis is the word given to describe our eye’s ability to perceive depth and in order for it to be at its optimum level it is essential that both eyes are focussed and working together. A pair of glasses can significantly improve depth perception for those people who have a prescription.
Getting tired quicker
If you find you are getting tired earlier in the day or after a shorter duration of certain tasks, then it may well mean your eyes are out of focus. Our brain is more stimulated when our vision is perfect, meaning we feel awake for longer. Blurred vision can result in tiredness and lack of concentration which can affect performance. You may also find that you are not performing to your maximum at work as you will find you need to take breaks more frequently.
If you have answered yes to any of the above five signs then you should consider booking yourself in for an eye test. Ignoring the problem will only make things worse and, more importantly, you could be driving around illegally. Having perfect vision will mean you carry out your everyday tasks both at home and at work to the highest possible level. If you really hate the idea of wearing glasses then don’t let this put you off going to the opticians as there is always the option of contact lenses.
