Blurred vision refers to a lack of sharpness in vision or the images you are seeing. You can say, it is an inability to see the objects in fine detail. Blurred vision may result from abnormalities such as myopia, nearsightedness, farsightedness, presbyopia, or astigmatism. Such causes can be improved by using corrective lenses (or eyeglasses). However, sometimes it may signal the presence of eye disease.
Blurred vision may be experienced in one or both the eyes. This would depend on the cause. Blurry vision can also be a symptom of various other health conditions that may not be directly related to the eye, such as migraine or stroke. Some medications may also lead to blurring of vision temporarily, as a side effect. Sometimes, it happens along with other symptoms, depending upon its cause. It may be accompanied by headache, sensitivity to light, or redness and irritation of the eyes.
Blurred vision can also be known as a clouded or dim vision.
Causes of Blurred Vision
A sharp and clear vision helps you navigate your world. Whether you need to read the road signs or if you are watching a movie in a theater. Cloudy vision can make you feel like all things you are watching are draped by a haze, and nothing is in focus.
It can affect your entire line of sight or just parts of your vision. This could be your peripheral vision, or how one particular side is visible to you. It may even be a blurred vision in only one eye.
The blurred view may be caused by one or more of the below listed possible reasons:
You may have been focusing on a task for a long time. Or staring at the phone’s screen and forgot about blinking. Blinking spreads tears across the surface of your eyes. And keeps them lubricated, clean, and refreshed. We tend to blink less often when we are concentrating on something or some work. You need to remind yourself to blink more often, take breaks, remember the 20-20-20 rule – every 20 minutes, look at an object kept 20 feet away for 20 seconds, or look around to prevent vision strain.

Eye tissues may be inflamed because they got hurt from something. The herpes virus from a cold sore could move to your eye. Sleeping in your contacts, not cleaning your glasses properly, or not changing them when you should. Ignoring certain things can also lead to infections. When the contact lens is worn for longer durations, protein may build up from the tear film on them, causing cloudy vision. Immune system diseases that affect other parts of your body, like psoriasis, and rheumatoid arthritis, etc, can also cause inflammation in your eye.
Age & Cataract
On crossing the age of 40, you’ll notice it’s harder to focus on close tasks such as reading. The clear lens inside your eye doesn’t remain as flexible as at a young age. It’s a normal part of getting old. You should get your eyes examined at eye hospital Delhi. And get yourself prescribed reading glasses, contacts, or surgery, as required.
In cataract the clear lens in front of the eyes get cloudy. Though it is more common amongst the elders. But younger people can also get them. It gets harder to see at night. And you become more sensitive to glare.
Preeclampsia happens when blood vessels in your placenta are too narrow and don’t work right. This very serious condition brings with it headaches, shortness of breath, or feeling like throwing up. As well as blurry vision.
You must consult your doctor right away. Without proper treatment, it can cause life-threatening difficulties.
When we have dry eyes or feel that there is some tiny particle inside, we start rubbing our eyes. This can damage the cornea. The cornea can also be due to an eye injury. But it’s more likely to occur from a bit of dust or sand. Instead of rubbing, you should rather try washing your eyes with clean water. Or you can blink rapidly a few times to hydrate them. But DO NOT rub or touch your eyeball. If the condition persists, visit your eye doctor.
When your eyeball has an oval shape and not round. Or your cornea or your lens doesn’t have the right curve. Then the light cannot focus on the right spot. That can lead to seeing clearly only at certain distances (Nearsighted and Farsighted) or Astigmatism (distorted vision). Most often, such conditions can be corrected with eyeglasses, contact lenses, or minor surgery.
In the case of diabetes, high blood pressure, poor nutrition, or other such diseases that are caused by our sedentary lifestyle, the eye organ gets affected. People with diabetes are likely to get retinopathy and other eye diseases, When your blood sugar goes out of control, fluid may seep into the lens of your eye and it swells.

Almost 1 out of 4 people with migraine get visual auras. It starts usually before the pain and remains for about an hour. However, if it occurs in only one eye, it may be serious. Check with your doctor immediately.
Damage to Retina
The retina is a surface at the back of your eye where the light gets focused and the image is formed. If that surface gets swollen or torn, the image gets distorted or lost. Poor diet, smoking, previous eye injuries, eye diseases, and health issues such as high blood pressure, high cholesterol, and diabetes can increase the odds of problems like macular edema and a detached retina.
People who have warning signs should visit an ophthalmologist right away. People with other diseases that sometimes causes retinal damage (for example, diabetes, high blood pressure, or sickle cell disease) should get their eyes checked as soon as possible. Preferably, within a few days. However, if vision has been worsening gradually for months or years but has not been severely impaired and there are no warning signs, waiting a week or longer is usually not harmful.
Eye examinations should be done at a good Eye Hospital Delhi, by an ophthalmologist or optometrist. Ophthalmologists are better because they specialize in the evaluation and treatment (surgical and nonsurgical) of all types of eye disorders. Optometrists are practitioners who specialize in diagnosing and treating the refractive errors (by prescribing glasses or contact lenses). However, sometimes the optometrists can also diagnose certain other eye problems and, further, refer the patient to an ophthalmologist for treatment. People should usually see an ophthalmologist if they have warning signs.
In people with blurred vision, below symptoms and characteristics are, mostly, a cause for concern.
- Sudden change in vision,
- Severely reduced vision, particularly in only one eye, even if the signs began gradually,
- Eye pain (with or without eye movement),
- Loss of vision in a specific area (called a visual field defect),
- Human immunodeficiency virus (HIV) infection or AIDS, or other condition affecting the immune system. For example, the use of chemotherapy or other immune-suppressing drugs.
The treatment of blurry vision depends solely on the cause of the blurring. Refractive errors like myopia, hyperopia, and astigmatism can get corrected by using eyeglasses or contact lenses. With the contact lenses being a more comfortable option. But it is important to be careful about your contacts. Wear them correctly, keep them clean properly, and avoid leaving them inside the eyes for a longer period than advised.
If you are looking for something more permanent, you can opt for LASIK eye surgery as well. It is a quick, painless procedure. And gives you better vision with long-lasting results.
Blurry vision that is caused due to other health problems like diabetes can be addressed by taking the right medication for those issues.
Remember not to strain your eyes too much. Try to rest your eyes. Prevent fatigue and get sufficient sleep. Ensure that your eyes do not get dry. Use lubricating eye drops if required.

- Diabetic Retinopathy can be treated with surgeries like Vitrectomy, Laser Coagulation, and Laser Surgery.
- Blurry Vision during Pregnancy is a temporary condition. Therefore, generally, only eyeglasses are prescribed. The normal vision should return within 6 weeks of delivery.
