Blindness is indeed an inability to see the objects clearly, even light. There are many Eye diseases that cause blindness. It is the greatest fear of everybody to be blind because it is a very useful and important grant by Allah Almighty. This God gifted part of our special senses enables the human to see the beauty of the creature, to see the others and to see yourself.
Alas! A blind man is unable to see himself or nature, this is the biggest loss in life.
Absolute blindness is referred to known as “no light perception,” indeed it is when a person is unable to tell the difference between the light and dark, even can’t percept the light when a bright light is shined into his/her eyes. This condition is somehow rare. Assistance from the government and foundations is available for these persons and many foundations are working for such individuals.
Lots of eye diseases have no symptoms early on. Some eye diseases are painless, and you don’t see any change in your vision until the disease has become advanced or chronic. Therefore, the best remedy to protect the eye vision is, go for regular professional eye examinations. On examinations, if you feel any change in your vision, your eye professional will suggest you best-corrected eyeglasses.

Eye Diseases That Cause Blindness
Blindness can be sudden but mostly it is a gradual process. Due to chronic eye diseases, optic nerve continually being damaged and retinal cells being destroyed. No doubt, almost all eye diseases are curable, but if diagnosed early. Otherwise, it can lead to irreversible vision loss or blindness. Thousands of eye diseases are present among the population that causes reversible or irreversible blindness. Some of them genetically present, or some are acquired after birth. A few following conditions and eye diseases are discussed here which can cause eye blindness if left them undiagnosed or untreated.
A cataract is actually a clouding of the lens. It is an age-related process and reduces the vision. This cloudiness of the lens drops visual acuity to 20/200 or less because the cataract does not allow enough light to reach the retina in the back of the eye. This surgical intervention usually results in significantly improved visual acuity.
Amblyopia is a condition in which a person has vision loss since early childhood because the eye and the brain are not working in a balanced or coordination way. A child with amblyopia suffered from loss of vision in an affected eye because of amblyopia affects only one eye. Meanwhile, the affected eye is known as “lazy eye.” It is curable if treated earlier. If it is left untreated, it can lead to permanent vision loss.
Available Treatment options include prescription refractive eyeglasses or vision therapy exercises. Recommended and accepted the way to cure the lazy eye is wearing an eye patch over their stronger eye in order to force the affected eye to function as it should.
3- Macular degeneration
Macular degeneration is basically a common eye disease that causes central vision loss. Central vision is actually what you see when you are looking straight ahead. On the other hand, your peripheral vision is what you see on the side when you are looking straight ahead. Keep in mind, macular degeneration never causes total blindness because it does not affect your peripheral vision.
4- Strabismus (Crossed Eyes)
Crossed eyes (or strabismus) are also common eye diseases that cause blindness because such patient’s eyes are not able to align on the same point, ok the same axis and at the same time. They are looked to be misaligned or pointed in different directions. These crossed eyes are surgically reassigned into the same axis at the same time.
5- Raised Intraocular Pressure / Ocular Hypertension
Ocular hypertension is actually an increase in pressure in the eye that is above the normal range. This raised pressure compresses the optic nerve and if it is untreated for a long-time, this compressed optic nerve begins to die. Vision begins to compromising.
Glaucoma is a condition of the eye when a build-up of fluid in the eye creates a high pressure due to obstruction in the fluid drainage system. This high fluid pressure damaging the optic nerve gradually. It can be treated with opening the drainage system of eye fluid (aqueous humor). This drainage system can be opened by medicines, eye drops, or surgically.
7- Corneal Diseases
A corneal laceration is also common occurring eye diseases that cause blindness. What is the cornea? The cornea is the clear, circular “window” at the front of your eye and covers the pupil. It helps to focus the light that coming and also control the amount of light to be entered. It can easily be damaged by any disease, injury, infection, and exposure to harmful toxins. Corneal damage is associated with redness, pain, blurred vision, Water from the eye, or a halo effect.
