What Are The 7 Causes Of Blindness?

Blindness is the state where an individual loses vision. In this condition, lack of vision reaches beyond the periphery of glasses to correct it. Even eye drops, other medical therapies, or surgery will not work in this condition. 

Losing vision suddenly becomes a dire emergency. Hence, one must urgently seek immediate medical help. The blog discusses the 7 major causes of blindness. 

Symptoms Of Blindness 

The question is how one understands that an individual will get blind. Based on different studies, one may notice some symptoms:

• Watery eyes
• Decreased vision
• Seeing halos around a source of light
• Seeing abrupt changes in vision quality
• Intense pain in the eyes
• Double vision
• Seeing floaters
• Lines looking wavy or distorted

Upon observing one of these signs, one must immediately seek assistance from a professional optometrist in Houston. 

7 Causes Of Blindness

Blindness is among the most common health conditions in the USA and globally. About 1 million people in the USA are blind, and experts speculate that the figures may double by the year 2050. Many causes result in permanent loss of sight. However, we have discussed 7 of them in this blog. 

1. Diabetic Retinopathy

People who are diagnosed with the complexity may become blind. In this condition, high blood glucose levels affect the eyes’ blood vessels. 

The positive is that a simple diabetic screen test can detect it. Hence, to treat these issues, one must consult a professional optometrist without allowing the problem to worsen to the point of no return. 

2. Macular Degeneration 

People in their sixties must know about age-related macular degeneration (AMD). It is one of the most common causes of low vision. In this condition, straight lines tend to appear crooked. Consider it an early sign. Smoking and family history are major risk factors. 

3. Cataract 

It is one condition when an individual will find the eyes’ lenses get hazy and clouded. The problem can occur at any age. Genetics, medication, diabetes, and prolonged exposure to sunlight may develop complexity. It is one of the most common causes of blindness observed globally. 

4. Amblyopia

Another name for it is Lazy eye. The problem starts and matures in childhood. In this condition, one may find interpreting information with one eye difficult. The problem aggravates with age. Many parents do not understand that their children are facing this problem. 

5. Trachoma

Trachoma is an infection caused by the bacteria Chlamydia Trachomatis. When affected by the bacteria, your eyelids may get scarred, gradually leading to blindness. 

6. Strabismus

Strabismus can occur alongside or without Amblyopia. When the muscles surrounding your eyes do not work properly, the sight of both eyes does not align. This makes object identification complex for the brain. Risk factors for this eye disease include family history, eye or brain injury, or even cerebral palsy. 

7. Uncorrected Refractive Errors 

Another common cause of blindness is refractive errors. These errors cause blurred vision and, if left untreated, may gradually lead to blindness. To restore sight, one must consult a revered eye professional to diagnose the problem early. Refractive surgeries usually treat the problem.

Blindness can bring doom to one’s life on earth. Hence, it is always better to see an Optometrist. Our professionals have the know-how and technology to diagnose problems promptly and provide adequate treatment.
