Why Is My Vision Blurry?

Blurry vision is a common eyesight problem that many people live with. If you have a refractive error, such as shortsightedness, longsightedness, or astigmatism then this has probably already been picked up by your eye doctor and treated with corrective lenses or laser vision correction.

However, vision doesn’t tend to remain the same throughout a person’s life. Changes can occur—sometimes over time or more quickly.

The following looks at the reasons you might be suffering from blurry vision.

What causes blurry vision?

Blurred vision can be caused by many reasons. The most common is that the light doesn’t travel correctly through the eye, causing vision to be less than clear. This is known as a refractive error and manifests as either longsightedness, shortsightedness, or astigmatism. These can evolve and may worsen as you age.

While these are the most usual causes, there are other reasons that vision might be less than 20/20. Blurred vision can affect one or both eyes and, in some cases, can be described as cloudy, rather than blurred.

The different causes of blurry vision

The following are some of the other causes of blurry vision.

  • Tired eyes or overuse: This is common if you spend too long staring at a screen without taking proper breaks. The tiny muscles that control the changes in your vision become tired and you might find your eyes become watery. This can lead to temporary blurring of vision.
  • Dry eye: This is a condition where the eyes don’t produce enough tears to lubricate the eye. It can also be that the tears are of insufficient quality. The condition commonly leads to blurred vision.
  • Presbyopia: The medical name for the normal aging process of the eye. Once we pass 40, the lens of the eye tends to become more rigid, so causing blurred vision either at distance, close up, or both.
  • Pregnancy: Hormonal changes during pregnancy can cause your vision to change or become blurry. While this is often temporary, it’s important to discuss this with your ophthalmologist and obstetrician. That’s because it can, in some cases, be a symptom of gestational diabetes or hypertension.
  • Ocular migraines: Many people experience an ‘aura’ that precedes a migraine. This might be flashing lights, zigzag patterns, or blurred vision.
  • Medication: Some types of medication/eye drops can cause blurred vision.
  • Cataracts: The formation of cataracts can cause blurred or clouded vision. Cataracts are most commonly experienced in the later years of life. They should be monitored by your ophthalmologist and can be operated upon when they reach a certain stage.

These are some of the most common reasons for blurry vision. However, if you experience worsening symptoms or if it has a rapid onset then it’s vital to seek expert help straight away.

Treatment for blurry vision?

  • Diagnosis and treatment

Diagnosis and treatment

The reason for your blurred vision will be determined after various diagnostic tests. Much blurred vision can be treated through a prescription for eyeglasses or changing the prescription you already have.

However, it can’t be over-emphasized enough that if you experience a sudden change in vision then you should seek emergency help. 

For example, sudden blurry vision could be a symptom of a detached retina. Or, if experienced in a single eye could be a symptom of a macular hole or detached retina. The sudden onset of blurred vision can be a symptom of a stroke and those who suffer from diabetes could suffer blurred vision because of worsening diabetic retinopathy.

Whatever the reason for your blurred vision, getting it checked out is always the wisest course of action.
