There can be many reasons for blurred vision, know the reason and when to consult a doctor

News Topical, Digital Desk : It is normal to have blurred vision with increasing age or due to excessive use of screen. This can be temporary or permanent. The reason behind blurred vision can be minor or serious, in such a situation ignoring the symptoms is not good for the health of the eyes. Let's take a look at the reasons for this blurred vision.

Eye problems may be the reason

• Myopia: In this, the person has difficulty in seeing distant objects, while nearby objects are clearly visible.
• Hyperopia: In this, the patient can see distant objects clearly, while he has difficulty in seeing nearby objects.
• Astigmatism: In this, the shape of the patient's cornea is abnormal due to which the light in the eye is not able to focus equally. In such a situation, things appear blurry whether from far or near.
• Presbyopia: This eye problem reduces the ability to focus on near objects as we age. It is seen in people over 40 years of age.

Dry Eyes

This problem occurs when the eyes are unable to produce enough tears or the tears dry up too quickly. This causes irritation, redness and blurred vision in the eyes. The reasons for this can be:

• growing old
• Hormonal changes
• Eye Surgery
• certain types of medications
• looking at screens for long periods of time
• Pollution or low air humidity

Eye diseases can also be the reason

• Cataract: It causes blurred vision. One starts having trouble seeing at night and also facing light. This problem is seen in most people after the age of sixty.
• Age-related macular degeneration: Also known as AMD, this condition affects the centre of the retina. This causes blurred vision, especially in the centre of the eye. Although there is no cure for this, its speed can be slowed down by making some lifestyle changes.
• Glaucoma: Due to excessive pressure in the eyes, the optic nerve gets damaged. In this, the vision of the eyes gradually decreases. It is divided into two parts, primary and secondary. While primary glaucoma occurs without any reason, secondary glaucoma occurs due to injury to the eye, diabetes or long-term use of steroids.
• Diabetic retinopathy: This happens when the blood vessels of the retina get damaged due to high blood sugar. This causes  blurred vision  . Sometimes in severe cases, the eyesight is completely lost. Although its symptoms are not visible in the beginning, but in the advanced stage, symptoms like seeing waves of light in front of the eyes, dark spots and frequent changes in vision are seen.

Blurred vision may occur suddenly due to these reasons

• Stroke
• Retinal Detachment
• Injuries
• Migraine
• increase or decrease in blood pressure
• Low Blood Sugar

consult a doctor in such a case
