    Blurred Vision – Causes & Treatment

    26 August, 2023

    Blurred vision is a common symptom in people of all ages. This condition can stem from living habits, using the eyes, etc. However, it can also signify more severe look and body diseases. Join Prima Medical Center Saigon to learn the causes of blurred vision and effective treatment through the article below!

    What is blurred vision?

    Blurry vision is the phenomenon of vision impairment; objects in front of the eye lose sharpness at a distance or both. Blurry vision can occur in one eye or both eyes.

    Blurry vision is the most apparent manifestation of patients with refractive errors. However, it can also be an early sign of more serious eye diseases, especially when some symptoms accompany the eyes. Following icon:

    The vision is blurred as if there is a fog blocking the eyes.

    Decreased peripheral vision (tubular field of vision): vision in the periphery (rim) may be blurred or darker than the center.

    Obstructed vision constantly feels that floating objects or halos make it difficult for the eyes to focus and see clearly at a fixed distance.

    Causes of blurred vision

    Refractive error

    Blurred vision is shared when the eyes have refractive errors (near, far, astigmatism). An eye with refractive error is an eye that has abnormalities in the optical composition, causing light rays to focus in front of or behind the retina, making the image of the object that the eye sees blurry and blurred. Refractive errors cause patients to see, eyestrain, and eyelid twitching, affecting activities and quality of life.


    Dr THAO Vo, Chief Medical Officer, Prima Medical Center Saigon explained that blurred vision can be an early warning sign for cataracts. Cataracts (cataracts, cataracts) are a phenomenon where proteins gather in clusters, creating opaque areas in the lens, scattering light through, and blocking sunlight from reaching the retina. Cataracts make the patient’s vision impaired and blurred vision and, if not treated promptly, can lead to blindness. In addition, mature cataracts can cause Glaucoma, red eyes, sore eyes, and headaches. At that time, not only the patient was permanently blind but also had to remove the eyeball.


    Dr AN Trinh, Head of General Ophthalmology shared when you have Glaucoma, the pressure in your eye will increase, damaging the optic nerve and leading to loss of vision, even blindness, if not treated promptly. If blurred vision is combined with decreased peripheral vision (tubular field of sight), this is likely a symptom of Glaucoma.

    Macular degeneration

    Macular degeneration can cause blurred vision because part of the retina (macular) is damaged over time. It is the most common disease in the elderly and has the third highest risk of blindness worldwide.


    Blurred vision can be caused by keratitis because a foreign object in the eye affects vision. Some causes of keratitis include infections (viruses, bacteria) and allergies. This is temporary; the image will be restored once the disease is treated.

    Dry eyes

    Dry eyes not only bring a feeling of entanglement, pain, and discomfort but can also cause temporary vision fluctuations and blurred vision. Looks can be dry due to many causes such as weather changes, not blinking frequently, eyelid gland blockage, etc… When having dry eyes, the patient needs to be examined and treated to avoid this condition prolonging for a long time. Cause more severe eye problems.

    Eye Injury

    Suppose the eye encounters trauma from foreign objects (metal, glass, wood chips, etc.) or chemicals splashed into the eye. The patient’s vision will also be affected with varying severity in that case. Depending on the severity of the wound. When experiencing eye injuries, patients must go directly to reputable ophthalmology facilities for examination and treatment instead of self-treating at home to prevent the infection from worsening.
