7 Possible Causes of Blurry Vision

You see clearly under normal circumstances. Your vision, on the other hand, has become hazy today. What could be causing your blurred vision, and should you be concerned?

You could experience blurry eyesight for a variety of reasons

Straining of the eyes

Eye strain can be caused by long hours looking at a computer screen, phone, tablet, or other activity that needs a lot of visual concentration, such as night driving. As a result, your vision can get blurry. When you're at your computer, remember to blink frequently and to follow the 20-20-20 rule: look at something 20 feet away for 20 seconds after every 20 minutes of looking at the screen before returning to it. When you take time away from blue light screens or situations that cause eye strain, your blurry vision will improve.

Dry eyes syndromes

Your eyesight may get blurry if your eyes become too dry. Dry eyes are caused by an aberrant tear film, which is caused by a decrease in tear production and/or evaporation of the tear film. Dry eye syndrome can be caused by a variety of factors, including autoimmune illnesses, allergies, medicines, age, and menopause. Dry eye syndrome and fuzzy vision can be exacerbated by environmental factors such as low humidity air, fans, and prolonged video screen time. Over-the-counter artificial tears are commonly used to treat dry eyes for temporary relief, but behaviour modification is needed for long term relief. Some supplements may help to protect the tear gland and promote healthy tear production.

Scratch on eye cornea

A corneal abrasion is a scratch on the eye's surface that causes pain, a foreign body sensation, tears, and blurred vision. Minor abrasions heal rapidly and can be treated with lubricant drops, while antibiotic drops are sometimes used to prevent infection. To reduce inflammation and scarring, more serious abrasions may require antibiotic ointment and steroids. To assist in healing and pain relief, a specific bandage contact lens may be required in rare circumstances. The blurry vision will go away once the corneal abrasion heals fully.

High blood sugar

Patients with diabetes who have sudden blurred vision may be suffering a blood sugar surge. High blood sugar levels over an extended period of time may result in a change in your glasses prescription. If you suspect your blood sugar is high, take a reading to confirm it, then follow the steps you and your doctor agreed on for safely lowering it to reduce your blurred vision problem.

Eye retina detached

The retina takes light from the lens and converts it into neural impulses that are sent to the brain via the optic nerve. A detached retina is a dangerous ailment that should be addressed by a retinal expert as soon as possible. A quick start of flashes in the peripheral vision, black floaters, and a black curtain shade blocking part of the vision in one eye are all common symptoms, and you will not feel the pain caused by retina detachment.


When you get a migraine or a strong headache, your eyes become sensitive to light and your vision becomes blurry. When your migraine is gone, these symptoms usually go away as well.


Sudden intense blurred vision could indicate a stroke, which could occur in the brain or merely in the eye. This is a medical emergency, and you should get expert help right away.

It is recommended that one receive an eye exam at least every 2 years or more frequently if one already has refractive errors. Preventative care is the key to literally preventing future problems. Always take precautions to protect your eyes on a daily basis. Wear UV-blocking sunglasses when you're outside, computer glasses if you work or spend a lot of time on the computer, and get the complete eye protection nutrients to keep your eyes healthy.
