This is a list of the commonly occurring eye problems in humans. These conditions mentioned here are quite prevalent and most of them can be treated using simple modifications or surgical procedures.
Myopia is commonly known as short-sightedness or near-sightedness. A person suffering from this condition can see nearby objects clearly but is unable to see distant objects clearly. For instance, the might be able to read or sew but will not be able to easily identify someone walking on the other street.
Myopia can occur due to two reasons.
- The eyeball might be elongated. This causes the rays of light from a distant object to meet ahead of the retina.
- The muscles holding the eye lens, known as ciliary muscles, might not be able to stretch the eye lens properly.
It is found that myopia generally affects children. If your child is able to read from their textbooks clearly but not able to see what’s written on the classroom blackboard, then it might be a situation of myopia.
The general correction for myopia is by using spectacles with concave lenses. They help the images to focus directly on the retina.
Hyperopia, also known as hypermetropia, is far-sightedness. It is the opposite condition of myopia, in which the person can see faraway objects clearly but not nearby objects. Such people find it difficult to do tasks such as reading, sewing, or even seeing the time on their watch, but they can see distant objects quite clearly.
Hyperopia could occur because:-
- The shape of the eyeball is flattened, which causes the rays of light to fall behind the retina, or
- The ciliary muscles stretch too much, due to which the eye lens has a high focal length.
Hyperopia is rarely observed in children. When people cross the age of 40, the ciliary muscles naturally become weak, and people might suffer from a condition of old-age hyperopia, which is known as presbyopia.
This issue is corrected by using spectacles with convex lenses of suitable focal length.
Sometimes, people have myopia since childhood and then develop hyperopia later on in life. Such people use bifocal lenses that can help with both the conditions.
Cataract is a very common eye disorder that occurs in elderly people. In this condition, the eye lens of the eye becomes cloudy and opaque, which impairs vision drastically. This is a very common worldwide condition. In the US alone, there are over 40 million cataract patients, most of who are over the age of 40 years.
The human eye lens is made up of a jelly-like proteinaceous substance. This material is transparent. But as the eye is used over the years, the protein molecules might clump together and become opaque. This is what leads to the onset of cataract.
The risk factors of cataract might increase if:-
- You spend a lot of time in sunlight without proper protection
- You have high blood sugar or high blood pressure
- You use steroid medications
- You smoke
- You have recently undergone any hormonal replacement treatment.
Though cataract can lead to near-blindness in some people, the good news is that cataract is completely treatable through a minor surgery. After a few days of care, the person is able to see again just like before.
The inside of the eye is filled with two different fluids, known as aqueous humor and vitreous humor. Working in combination, these fluids manage the pressure within the eye and also the refractive index, which helps us in obtaining clear vision.
However, in some people, this fluid balance is disturbed. When that happens, the condition known as glaucoma arises.
A person suffering from glaucoma will have added pressure buildup in the eye, which can lead to impairment of vision and damage to the internal parts such as the eye lens and the optic nerve itself.
Though glaucoma can be a seriously debilitating condition, it can start out with no symptoms at all. Despite the pressure buildup, people might not experience any pain or other similar effects. However, glaucoma can be identified during an ophthalmic test.
The following are some of the reasons that might cause glaucoma:-
- Some kinds of eye injury
- Infection of the eye
- Inflammations of the eye
- Low supply of blood to the eye due to blockages in blood vessels
Glaucoma can be treated. Simple cases can be treated just by the use of the right kind of eye drops. In severe cases, surgery might be recommended.
A healthy human eyeball is perfectly spherical. This is absolutely necessary because it helps the rays of light to focus directly on the retina. However, in some cases, the spherical shape of the eyeball is lost. If these irregularities exist in the eyeball, the rays of light will not be able to focus on the retina and that could lead to severe impairment of vision.
The irregularities in the shape of the eyeball could be congenital (since birth) or it could be due to some injury.
The correction of astigmatism can be done by using cylindrical lenses. Recently, laser treatment techniques have been developed to treat astigmatism, and they can provide permanent relief from the condition.
Night blindness is a condition wherein the person is not able to adjust the focus in dim light conditions. Even when a healthy person walks in from a brightly-lit room to a dark room, it might take a few seconds to adjust to the dim conditions. However, a night blind person will not be able to do so for a long time. In some cases, the reverse might also happen. That is, the person might find it difficult to adjust their vision when they move from a dimly-lit room to a brightly-lit one.
Night blindness is a dietary deficiency disease. It is usually caused due to the lack of vitamin A in the diet, which is found aplenty in vegetables such as carrots. By including vitamin A rich foods in the diet, this situation can be slowly corrected. There are no surgical methods required to correct this issue.
Night blindness is found to be more prevalent in male children.
