It must be very disturbing if you have visual disturbances. If you experience decreased vision in the afternoon or when the lighting is dim, then you may have night blindness. On this occasion we will discuss. Treatment of nearsightedness.
Night blindness, also called nyctalopia, occurs due to impaired function of stem cells in the retina. If left untreated, night blindness experienced can interfere with activities, especially if done in the afternoon and evening.
The cause of nearsightedness
Under normal conditions, the eye can adjust to light or dark conditions in a short time. In people with night blindness, this ability is reduced so that the eyes find it difficult to adapt when the light is dim. Apart from damage to stem cells, night blindness can also be caused by genetic factors or vitamin A deficiency.
Other factors that are thought to increase the risk of night blindness include nearsightedness, cataracts, retinitis pigmentosa, glaucoma, keratoconus, and Usher syndrome.
Treatment Options to Overcome Night blindness
Diagnosis of night blindness begins with a physical examination. To confirm the diagnosis, supporting examinations are needed in the form of color tests, eye refraction tests, slit lamp examinations, pupillary reflex tests for light, retinal examinations, visual acuity checks, electroretinogram (ERG), or field examinations. Blood tests are done to check the levels of glucose and vitamin A in the blood.
After the diagnosis is determined, the sufferer will receive treatment according to its severity. Patients are generally advised to use minus-adjusted contact lenses or glasses. Drops are used to reduce eye pressure in people with glaucoma. The eye drops work by reducing fluid build-up in the eye. Oral medications are recommended if eye drops don’t treat night blindness.
If night blindness is caused by a deficiency of vitamin A, sufferers need to pay attention to food intake and take vitamin A supplements. If people with night blindness have cataracts, surgery is needed to replace the opaque lens with artificial clear lenses. What about night blindness caused by genetic factors? In this case, night blindness cannot be treated. Patients are only advised not to drive or do activities without sufficient lighting at night.
How to Prevent Night blindness
Not all cases of night blindness can be prevented, especially if it is caused by genetic factors. If night blindness is caused by factors other than genetics, there are several things that can be done, including:
- Consuming food sources of antioxidants and high in minerals. These include fruit (such as apples, pears, grapes, bananas, oranges, pineapples, papayas, strawberries), vegetables (such as broccoli, asparagus, tomatoes, red cabbage, red sweet potatoes), and nuts (such as pecans, walnuts, almonds) .
- Consume food sources of vitamin A to prevent vitamin deficiency. For example, sweet potatoes, carrots, pumpkin, mangoes, spinach, mustard greens, milk, and eggs.
- Routinely monitor blood sugar levels, with special tools independently at home or going to health facilities.
- Using sunglasses when on the move in the sun. That’s how to treat night blindness that needs to be known. If you have eye complaints, don’t hesitate to talk to a specialist
