The reasons why your eyes are blurred

There are many reasons why your eyes are blurred, including worrisome reasons that can lead to permanent vision loss, such as diabetes.

See your doctor if you have blurred vision.

1. Eyes are dry

One of the most common causes of blurred vision is dry eyes. If your eyesight improves after blinking, you may not need to worry.

The cornea, dome-shaped surface in front of the eye, needs to be lubricated so you can see clearly. If the eye does not produce enough water or tears of poor quality, the cells on the cornea peel off. When the cornea is dry, the eyes are like looking through an oiled glass.

Dry eyes can be caused by some drugs and even some lifestyle habits. Behaviors such as reading books, playing games, watching television or working on computers, can all be caused because they can reduce the frequency of blinking. So follow the 20-20-20 rule to relax your eyes: After 20 minutes doing these things, focus on looking at something 20 feet away in 20 seconds.

If your eyes are still dry and tired, consider using eye drops to make your eyes brighter. It is best to see a doctor because it can be a symptom of other diseases such as rheumatoid arthritis, lupus and thyroid disease.

2. Posture to sleep the night before

If your face rests on your pillow when you sleep, you may have severe dry eyes in the morning, due to night movement that causes your eyelids to rub on your knees to pull them away from the eyeball. The phenomenon of dry eyes occurs later. This is a sign of soft eyelid syndrome that usually occurs in overweight men.

Blowers can also blur your eyes, so be careful with fans in the bedroom. When sleeping, your arms or arms on your eyes are not good because they can put pressure, pinch on your tissue and limit blood circulation in the eyeball leading to blurred vision when you wake up.

3. Use some medicines

Many different drugs can cause blurred vision, including medications for high blood pressure, oral steroids, sleeping pills and medications for erectile dysfunction.

Additional attention should be paid to antihistamines including over-the-counter allergy drugs Zyrtec and Claritin. They can cause a chemical reaction for the body to reduce tear production. Even worse, antihistamines may also increase the risk of narrow-angle glaucoma, especially if you are farsighted or Asian.

If you are taking any medicine and notice that the eye becomes blurred and painful, see an eye doctor.

4. Using contact lenses incorrectly

A 2011 study published on Optometry and Vision Science showed that 85% of contact lens wearers claim to know how to care for glasses. But the researchers found that only 2% actually practiced well.

Scientists asked participants to remove glasses when sleeping. The reason is that the glasses are placed in the eyes for too long, which can cause eye irritation, increase the amount of protein, blur the eyes.b Moreover, wear glasses too long or improperly clean - a problem encountered in many study participants - May increase bacterial formation or even parasites on glass. That of course will increase the risk of serious eye infection.

So practice good glass hygiene: Remove contact lenses daily and wipe properly, replace the glass cleaning solution and replace the glass tray every month. If the eye is blurred and red or painful, see an eye doctor.

5. High blood sugar

Blurred vision can be a sign of illness not only in the eyes but in the whole body. In some cases, it may be one of the earliest warning signs of diabetes.

When blood sugar is too high, it can cause the fluid to move to the eye and the lens to change size. When the lens size changes, your eyes will have changed vision. The good news is that when blood sugar is controlled, vision returns to normal and it maintains its ability to control diabetes. Peak peak blood sugar levels can cause damage to the retina and even visual impairment.

So, if you notice vision changes such as a lot of blurred vision and reduced ability to focus on objects that are near or far away, see your doctor. An eye doctor may screen for diabetes as well as show you how to exercise your eyes.

6. Blurred vision of cataract

The risk of cataract increases with age, but you can get it at any age or even from birth.

Cataract is an area that is cloudy or translucent in the lens that makes the eyes look blurry (especially at night), making it difficult to read or distinguish colors. The disease is more common in people with diabetes who have to take drugs such as corticosteroids and smokers.

Identify signs and prevent cataracts before they damage your eyeball. Start by practicing: New research from Lawrence Berkeley National Laboratory (USA) indicates that running can reduce the risk of cataracts and the effect will be stronger if you exercise regularly.

7. You may have a stroke

Vision symptoms are common in people with epigastric stroke and transient ischemic stroke, also known as small stroke (TIA). The difference between these two types is that a small stroke is a temporary blockage of blood circulation, like when you bend a hose in the garden for a few seconds and then let go again. Meanwhile, a bloody stroke was like the faucet was completely removed. TIA is a warning sign that a bloody stroke may occur.

The symptoms of TIA can come very quickly and do not last too long, including blurred vision, flashing or seeing a curtain pulled up from the middle of the eye. You can also look gray or dark in seconds to minutes. Other symptoms include changes in hearing, smell, confusion, confusion or difficulty speaking.

Stroke is a medical emergency, so if you think you are showing signs, you should go to a doctor immediately. Treatment is most effective for several hours after onset.
