Blurred vision refers to lack of vision sharpness that causes your inability to see clearly. This can result due to abnormalities such as – farsightedness, nearsightedness, astigmatism or presbyopia which may be improved by wearing eye glasses or corrective lenses. It may also denote the presence of eye disease. Blurred vision can occur in one eye or in both the eyes, depending upon the cause. It may also be the reason of several conditions that do not involve your eye directly such as stroke or migraine. Taking different medications can cause temporary blurred vision in the form of side effect. Sometimes, blurred vision is also related to other symptoms depending upon its cause such as light sensitivity, headache, irritation and redness of your eyes.
It is quite common to suffer from blurred vision when you cannot see fine details during nearsightedness or farsightedness. It is necessary to seek medical care when you face quick change in your vision such as sudden loss of clear vision.
Most people suffer from blurred vision at some point of time in their life. There are cases when it will be temporary and will resolve itself without any treatment. However, some people will require further assistance to restore their vision clarity.
When you feel extremely anxious and stressed, the high levels of adrenaline in your body may cause some pressure on the eyes leading to blurred vision. People who suffer from long-term anxiety have eye strain throughout the day on a daily basis. Anxiety causes your body to become sensitised to any movement.
There is no specific answer for how long blurred vision may last. Some people suffer from sudden blurred vision in one eye or both the eyes. Others can experience blurred vision for a long time and even for a few weeks.
When you suffer from blurred vision, it is important to see an eye doctor. If you are experiencing painful red eye with or without any kind of discharge from the eyes, it is necessary to book your early appointment. Also, blurred vision might denote serious systemic disease like diabetes or stroke and so, an eye examination becomes very important for the ones who have risk factors with their eyes.
