27 Rarely Known Causes of Blurry Vision, Don't Underestimate It

Kapanlagi.com - Blurry vision is a common visual impairment that can be experienced by anyone. When experiencing it, our vision will become blurred, making it difficult to focus. Therefore, it is important to know the causes of blurry vision. By doing so, we can take preventive measures.

The eyes are indeed one of the important organs of the body. Unfortunately, the eyes are also often affected by disorders and diseases. These eye disorders often cause blurry vision. However, it turns out that blurry vision is not only caused by eye disorders. There are several other factors that can also cause blurry vision. What are they?

Summarized from liputan6.com, here are some causes of blurry vision that need to be known in order to maintain eye health.

1. Near-sightedness (Hyperopia)

A person with near-sightedness or hyperopia has difficulty seeing objects up close. However, they can relatively see objects from a distance. When trying to see objects up close, the vision becomes blurry. Therefore, if you feel your vision is blurry, it is possible that you also have near-sightedness.

2. Far-sightedness (Myopia)

Similar to near-sightedness, far-sightedness can also cause blurry vision. The difference is that far-sightedness makes it difficult for someone to see objects clearly in the distance. Both near-sightedness and far-sightedness can occur in one or both eyes.

3. Astigmatism

In addition to near-sightedness and far-sightedness, many people also experience astigmatism. Blurry vision is also a common symptom of astigmatism. Generally, astigmatism is caused by the failure of light rays to come to a single focal point on the retina. As a result, the vision cannot focus and becomes blurry.

4. Presbyopia

Presbyopia is a refractive condition of the eye that causes blurred vision due to the hardening of the lens inside the eye. This condition is usually experienced by older people. Presbyopia results in the loss of ability to focus on near objects.

5. Conjunctivitis

The next eye disorder that can cause blurred vision is conjunctivitis. Visually, conjunctivitis makes the eyes appear pink. This is caused by the adenovirus. In addition to attacking the eyes, this virus can also cause common flu, bronchitis, and sore throat. The attack of this virus can result in blurred vision for at least 2 weeks.

6. Cataracts

Cataracts are certainly a well-known eye disease. Cataracts are caused by the presence of protein in the eye forming clumps. As a result, the lens is obstructed in delivering clear images to the retina. Consequently, vision becomes blurred or foggy.

7. Hifema

Hifema is the term for dark red blood that pools in the front of the eyeball. The appearance of hifema can be caused by bleeding that occurs around the eye. Hifema results in increased pressure inside the eye, causing blurred vision.

8. Corneal Abrasion

The cornea is an important part of the eye. The cornea can experience abrasion, usually due to injury or scratching. The scratch or injury can be caused by flying dust, metal particles, sand grains, nails, animal claws, and so on. When the cornea experiences abrasion, vision also becomes blurred.

9. Optic Neuritis

The eyes can experience inflammation that results in blurred vision. One common occurrence is inflammation in the optic nerve, also known as optic neuritis. This inflammation is caused by autoimmune reactions or early multiple sclerosis.

10. Keratitis

Inflammation can also occur in the cornea, called keratitis. This inflammation is commonly caused by infection, due to wearing contact lenses for too long or reusing dirty contact lenses. So, make sure to use contact lenses more wisely and carefully.

11. Uveitis

Uvea is the term for a collection of pigmented structures in the eye, including the iris. If the uvea becomes infected or has an autoimmune reaction, vision will become blurry. In addition, the eyes will also feel painful.

12. Macular Hole

In the eye, the center of the retina or macula is responsible for central vision. Tears in the macula can develop and cause blurred vision. This can happen in one eye.

13. Macular Degeneration

Abnormal blood vessels can grow in the eye. This causes blood and other fluids to leak into the macula. This condition is called wet macular degeneration. When experiencing it, the vision in the eye will become blurry. In some cases, a person may even lose vision in the central part of the visual field. This disorder is closely related to age factors.

14. Glaucoma

Blurry vision can be a symptom of glaucoma. If experiencing it, emergency treatment is needed, namely closed-angle glaucoma. Closed-angle glaucoma occurs when the drainage system in the eye is blocked. As a result, the pressure inside the eye can rise very quickly, which can then cause redness, pain, and nausea.

15. Retinal Detachment

Retinal detachment can also cause blurry vision. Retinal detachment occurs when the retina detaches from the back of the eye, resulting in loss of blood supply and nerves. This disorder is characterized by the appearance of black spots followed by blurry or lost vision. In addition, other common symptoms are the sudden appearance of floaters and flashes, as well as continued declining vision.

16. Iritis

The cause of blurred vision is iritis. Generally, iritis occurs when autoimmune reactions or infections cause inflammation of the iris. In addition, iritis can also be caused by infections such as herpes. Besides blurred vision, iritis can cause sensitivity to light, also known as photophobia.

17. Effects of Eye Strain

Tense eyes often occur after prolonged focus on something. This commonly happens when reading a book or staring at a computer screen. This condition can clearly cause blurred vision and consistent decrease in visual quality.

18. Eye Floaters

Blurred vision can be caused by the appearance of temporary spots or floaters floating in the vision. Floaters usually appear when the vitreous, which is a gel-like substance in the eye, starts to liquefy. This is a common occurrence as age increases.

19. Using Contact Lenses Too Often

Wearing contact lenses can indeed make your vision clearer. However, it turns out that using them too often or excessively can have the opposite effect. This is because there is a potential for protein and other dirt to accumulate on the lens in the tear layer. This is what then causes blurred vision.

20. Side Effects of Lasik

Lasik surgery aims to improve vision. However, after the surgery, there may be side effects such as blurred vision. But there's no need to worry, this blurred vision will return to normal over time.

21. Side Effects of Eye Drops and Medications

In addition to lasik surgery and wearing contact lenses, using eye drops can also cause blurred vision as a side effect. This is because most eye drops contain preservatives that can cause irritation and vision problems.

22. High Blood Sugar

As mentioned earlier, blurry vision is not only caused by eye disorders. Other health conditions such as high blood sugar levels can also affect it. People with high blood sugar levels or diabetes tend to have blurry vision. This is because high blood sugar can damage the small blood vessels in the retina. In fact, high blood sugar can cause permanent eye damage.

23. Stroke

In addition to diabetes patients, stroke patients can also experience blurry vision. In fact, blurry or hazy vision is one of the common symptoms of a stroke. Blurry or loss of vision can occur in both eyes. This is caused by a stroke attack that affects the part of the brain that controls vision.

24. High Blood Pressure

High blood pressure can cause various health problems. It turns out, high blood pressure can also cause blurred vision. This is because high blood pressure can increase the risk of mini-stroke in the eye called venous occlusion.

25. Migraine

Migraine, especially those preceded by an aura, can also be one of the causes of blurred vision. When experiencing it, a person will see wavy lines or flickering lights and have other sensory disturbances.

26. Temporal Arteritis

Temporal arteritis or inflammation of the temporal artery can occur in anyone. If it happens, blood vessels around the temples can be involved, causing throbbing headaches in the forehead. As a side effect, vision will become blurred, even disappear.

27. Transient Ischemic Attack

The next cause of blurry vision is a temporary ischemic attack. Transient ischemic attack (TIA) is a mild stroke that lasts less than 24 hours. One of the accompanying symptoms is blurred vision. This symptom can occur in one or both eyes.

Those are among the 27 causes of blurry vision. Hopefully, they will be beneficial and inspire you to pay more attention to your eye health!
