9 Of The Most Common Eye Disorders

Abnormalities in the eye can be experienced by everyone without knowing the age limit. Although some eye disorders can heal on their own, some others also need treatment from an ophthalmologist.

Abnormalities in the eye should not be underestimated. Without proper handling, abnormalities in the eye can make it difficult for you to carry out daily activities. Some eye disorders can even cause blindness if left untreated.

Various Eye Disorders

Let's look at the eight types of abnormalities in the eye that are most often found below:

1. Nearsightedness

Nearsightedness or myopia is a condition when the eyes appear faintly seeing objects at a distance. Nearsightedness is generally caused by genetic factors. To overcome farsightedness, it is necessary to use glasses, contact lenses, or laser eye surgery (LASIK).

2. Farsightedness

Farsightedness is the opposite of nearsightedness, which is when the eyes appear faintly seeing objects at close range. Generally caused by genetic factors from parents who suffer from farsightedness. Handling farsightedness is the same as nearsightedness, namely the use of glasses, contact lenses, and laser eye surgery.

3. Night blindness

Night blindness is an eye disorder that occurs when a person cannot see in a place with bad lighting, a dark place, or at night.

Some causes of night blindness that doctors can still treat, including cataracts, vitamin A deficiency and farsightedness. But until now, there has been no cure for cases of night blindness experienced since birth.

4. Conjunctivitis

Conjunctivitis or often called pink-eye is an eye disorder that occurs due to inflammation of the conjunctiva (the thin membrane that lines the eyeball and inner eyelid).

This condition is usually caused by bacteria, viruses, allergies, to exposure to cigarette smoke, dust or certain cosmetic items. Therefore, make it a habit to wash your hands well as one of the preventions of eye disorders.

5. Astigmatism

Astigmatism is an eye disorder caused by a curvature of the cornea or an imperfect or uneven lens.

This condition results in changes in the location of the fall of light on the retina, thus causing vision to be faint or shaded. This eye disorder often occurs due to hereditary factors.

6. Color blindness

You are declared to be color blind if you cannot see certain colors or are unable to distinguish one color from another (usually red and green).

This condition occurs when cone cells or color cells in the eye do not work normally. Generally color blindness is suffered from birth, but can also develop in adulthood due to the influence of consumption of drugs or the impact of certain diseases.

7. Cataracts

Cataracts are eye disorders that occur due to a buildup of protein in the lens of the eye, thus making a faint vision. This pile of protein can occur due to the aging process, ultraviolet radiation, diabetes, obesity, eye injury, or it could also be an inherited factor of birth. Cataract surgery is the right choice for cataract patients.

8. Glaucoma

Glaucoma is a neurological disorder due to increased pressure inside the eyeball. This increase in pressure is thought to be related to high blood pressure, the presence of obstruction in the tear ducts, or excessive use of corticosteroid eye drugs.

9. Pterygium

Pterygium is an eye disorder due to the presence of mucous membranes that cover the white part of the eye. This eye disease often results from frequent exposure to sunlight radiation. Symptoms can include red eyes, blurred vision, and itchy or hot eyes. The presence of the mucous membrane also makes the eyes like the slip of a foreign object. Pterygium can be cured by prescribing corticosteroid eye drops to prevent further complications or surgery.

Eye health needs to be maintained as well as possible so that its function is not disturbed. If you feel a complaint or abnormality in the eye, immediately check with your eye doctor so that appropriate treatment can be given.
