Blurry, unclear or burning eyes is a common eyesight problem. Any trouble with any of the components of your eye such as retina, cornea or optic nerve can cause sudden blurred vision. The lack of sharpness in vision results in the inability to see fine details. Clear vision helps you navigate the world, from reading traffic signs to making sure you do not miss a step in any wrong direction. In contrast to this, blurry vision makes you feel like someone has put a filter over your eyes and your life is no longer in focus.

Burning eyes can cause several problems, ranging from simple to complex. Itching, tearing, eye pain or eye discharge are the main symptoms of burning eyes. Mostly, burning eyes are caused by environmental influences such as high pollen count or strong winds. Moreover, similar sensations can indicate serious eye problems that require medical evaluation.

So, to select appropriate treatment, it’s important to first know the causes of burning eyes and blurred vision.

5 possible causes of blurry vision

Some of the common causes of blurry vision include-

  • Myopia

Nearsightedness or myopia is a condition in which you can see near objects but objects placed farther are blurry. Along with eye strain, squinting and headaches can also occur. It can affect one eye or both the eyes. Myopia often develops during childhood and adolescence. 

  • Hyperopia

The condition in which you see distant objects clearly but objects nearby may be blurry is a symptom of hyperopia or farsightedness. You may not be able to focus properly on close-up objects or doing so can cause unusual eye strain and fatigue. Also, in case of severe farsightedness, even distant objects may appear blurred.

  • Astigmatism

When you have a blurred vision at all distances , it is a symptom of astigmatism. It is usually caused by an irregularly shaped cornea which changes the way light passes, or refracts to your retina which causes fuzzy, blurry and distorted vision.

  • Presbyopia

If you’re over 40 and start experiencing blurry vision up close- when reading small print or newspaper, chances are this is due to presbyopia, a naturally occurring age-related condition.It is caused by a hardening of the lens of your eye, which occurs with age. 

  • Over wearing contact lenses

Wearing contact lenses for longer than your doctor  prescribes can lead to abnormal blood vessels growing in the cornea, known as pannus.

Contact lens overwear will cause proteins and other debris in your tear film to build up on the lenses. This may cause blurry vision and increase the risk of eye infections.

Treatment for Blurry Vision

Having mild blurry vision that comes and goes could simply mean tiredness, eye strain or over-exposure to sunlight.

But, if there are sudden or continuing changes in vision such as double vision, blind spots, dimness, tunnel vision, these could be signs of a serious eye disease, which requires you to contact a doctor immediately.Juice and candies help when blurred vision is a result of a decrease in blood sugar. Consuming foods that are high in fast-aching sugars are given for treatment. 

To sum up, treatment for blurred vision depends upon the underlying condition that’s’ causing your symptoms.

Eye drops, laser surgeries or medications are generally prescribed to control the underlying conditions.
