Blurry Vision

If you’ve been experiencing persistent difficulty in seeing things clearly, such as difficulty seeing straight lines, you may be suffering from blurry vision. Blurry vision is a potentially serious symptom that can be caused by a variety of health factors.

Blurry vision is a condition in which your eyesight is not as clear as it used to be. Blurred or double vision occurs when your eyes become too dry, inflamed, or tired, and you can’t see things sharply.

People with blurry vision may experience jerky or twitchy movements in their field of vision. They can also sometimes see halos around light sources, like lamps and streetlights.

Blurry vision may cause episodes of impaired vision and even blindness. Fortunately, most people recover from it on their own, but if you frequently experience it, you need to seek treatment.

12 Causes of Blurry Vision

1. Brain Tumor

Your eyes are controlled by your brain, and if there is a tumor in your brain, it can affect your vision. Tumors that put excessive pressure on the eye can lead to blurred vision.

2. Multiple Sclerosis

Multiple Sclerosis is a chronic autoimmune disease that involves inflammation in the optic nerve region, causing painless vision loss, blurred vision, and loss of color vision. This condition is called optic neuritis. Optic neuritis may even lead to temporary vision loss.

3. Diabetic Retinopathy

This is a complication of diabetes that affects the eyes. Diabetic retinopathy can lead to blurry vision, vision loss, and blindness, especially if not detected and treated early.

4. Detached Retina

A detached retina is a retinal detachment that separates the vitreous chamber from the retina. People with this condition experience flashing lights or floaters and blurred or absent vision.

5. Transient ischemic attack

A transient ischemic attack or TIA is a brief event where people temporarily lose consciousness. Blurred vision is a common symptom of transient ischemic attack (TIA).

6. Wet macular degeneration

Wet macular degeneration is a condition in which the vitreous gel that fills the eyeball hardens, which may lead to blurred vision.

7. Eyestrain

Eyestrain is often caused by inadequate exposure to screens. Sudden blurry vision is a common symptom associated with eyestrain.

8. High blood sugar

Elevated blood sugar levels disrupt the eye and swell its lens, which may lead to sudden blurred vision.

9. Macular hole

A hole in the center of the retina, the macula, can also lead to sudden blurry vision. Usually, there is blurry vision in one eye.

10. Over-wearing contact lenses

Sometimes people wear contact lenses longer than they should. This causes proteins and other debris to build in the eye, which can make your vision blurry.

11. Giant cell arteritis (GCA)

Giant cell arteritis (or GCA in short) is a rare, autoimmune disease that inflames the blood vessels in the temple. Blurry vision is a common symptom of GCA. Other symptoms include headaches and migraine.

12. Conjunctivitis (pink eye)

Blurry vision can be the result of inflamed conjunctiva. This condition is called conjunctivitis or pink eye. Usually, blurriness occurs only in severe cases.

Preventing Blurry Vision

The eyes are very sensitive, and you have to take care of them very carefully. If you experience issues in the eyes frequently, you should go for a proper checkup.

Here are some ways in which you can prevent sudden blurry vision.

  • Wear protective glasses and a hat if you work in the sunlight.
  • Treat your high blood pressure.
  • If your work is hazardous, try to wear safety glasses all the time.
  • Give up smoking.
  • Try to keep your blood sugar levels under control, especially if you have diabetes.
  • Keep your blood cholesterol levels under control.

Managing and Treating Blurry Vision

Natural Remedies

Instead of using random medications that come with side effects, try to focus on natural treatments.

The following are some natural remedies that will help you not only treat blurry vision but also give you back your lost vision and keep other eye-related problems at bay.

Give Your Eyes Some Rest

If you work too much and don’t let your eyes rest, you will end up damaging them. Make sure your eyes and your whole body are properly rested.

Control Your Screen Time

Radiations from digital screens can damage your eyes and your vision. Make sure you control your screen time and take breaks while you work in front of a computer.

Lubricate the eyes

You can activate your eyes’ sebaceous glands and lubricate your vision by massaging your eyes with a warm compress and even simply blinking. If your eyes are too dry, try over-the-counter eye drops.

Improve air quality

If the air you breathe is too dry, it can affect your eyes. In order to avoid dry eyes and blurry vision, make sure the air at your home or workplace is properly humidified.

Stop smoking

Quit smoking because it is among the major causes of vision-related problems.
