Blurred vision: What causes it and what can we do?

If you have blurred vision, things you see may not appear sharp or clear. You may experience blurred vision in both eyes or just one, depending on the cause. Sometimes everything you look at will be blurry, while other times only part of your field of vision will be blurry.

Blurred vision can also occur with other symptoms such as:

  • Headaches. 
  • Sensitivity to light.
  • Red eyes.
  • Irritated eyes.

What causes blurred vision?

Blurred vision can be caused by eye conditions, including:

  • Myopia 
  • Farsightedness.
  • Astigmatism.
  • Presbyopia (when your eyes find it harder to focus as you get older).
  • Dry eye syndrome.
  • Waterfalls.
  • Glaucoma.
  • Corneal damage.
  • Age-related macular degeneration.
  • Eye infection.
  • Problems with the retina, such as diabetic retinopathy.
  • An eye injury.

Blurred vision could also be a symptom of an underlying condition, such as:

  • Diabetes
  • Migraine
  • Head injury.
  • Low blood sugar.
  • Preeclampsia (high blood pressure) if you are pregnant.
  • Psoriasis.
  • Multiple sclerosis.
  • Brain tumor.

It can also occur as a side effect of medications you may be taking. As you can see, there are many causes, so we always recommend visiting our Ophthalmology Center in Santa Cruz de Tenerife for a thorough evaluation.

Treatment for blurred vision depends on the cause. It may include:

  • Eye drops.
  • Laser surgery or medication.
  • Glasses or contact lenses.

Can blurred vision be prevented?

It is very important to take care of your eyes, which is why we recommend annual eye checks with one of our extraordinary ophthalmologists in Santa Cruz de Tenerife.

Protect your eyes from ultraviolet light by wearing polarized sunglasses and a hat; protect yourself from injury by wearing safety glasses, especially if you perform hazardous work. Maintaining a healthy lifestyle and not smoking will also protect your eyes.

It's especially important to take care of your eyes if you have diabetes. Monitor your blood sugar levels and make sure you have healthy blood pressure and cholesterol levels. Consult our specialists if you notice any vision problems to prevent them from worsening.
