Night Vision Problems can be Completely Treated if Detected on Time!

Many people struggle with vision issues at night and also in poor light conditions. This is a treatable condition; however, leaving it untreated can result in complete night blindness. The success of the treatment depends largely on the cause that has triggered it – in case of night vision loss due to retinitis pigmentosa, the condition may not be treatable.

Understanding night vision problems

Our eyes have the natural capacity to adjust to the different light conditions. When we move from a brightly lit area to a darker one or vice versa, our eyes can quickly adjust to the new surrounding and maintain the clarity with which we will view the same. However, in some people, this adjustment may not naturally come. This will hamper the way they see things clearly and often come in the way of daily functioning. This may include his/ her difficulty in driving post sunset, difficulty in traveling through dimly-lit areas such as movie halls and restaurants, and so on.

Night blindness is also called Nyctanopia and some forms of it, especially when detected early, can be easily treated.

In the case of night blindness, the rods of the retina that are in charge of controlling vision in low light get impaired or degenerate. This hampers the vision and leaves the affected person looking for prompt medical assistance.

Causes of poor night vision

There are several causes that may result in affecting your vision at night or in poorly-lit conditions. This includes:

  • Cataracts are cell debris that buildup in the lens that decrease the vision clarity. This can also result in diminishing the vision at night. Blurry vision and halos around lights are common tell-tale signs that indicate the formation of cataracts.
  • People struggling with nearsightedness or myopia often complain about their inability to clearly see things in dim light conditions. Treatment of myopia generally helps better such conditions.
  • The inherited condition Glaucoma also triggers this issue in many patients. Intraocular pressure generally damages the optic nerve silently and if left undiagnosed or untreated, it may lead to complete loss of vision.
  • Retinitis pigmentosa typically affects young adults. This is a collection of hereditary vision disorders and the first symptom is usually loss in the night vision. This is mostly untreatable.
  • Deficiency of vitamin A and zinc aren’t directly related to night blindness. Nonetheless, these are considered as great foods that help maintain eye health. Also, vitamin A intake may remain ineffective unless zinc is also consumed in appropriate doses. Animal products can help replenish this loss; there are plant-based sources available too that you can consult with your doctor about in case you prefer so. Good sources of vitamin A include carrots, sweet potatoes, green leafy vegetables, fish etc.
  • Sometimes you may find it difficult to adjust to a normally-lit or poorly-lit ambience after over exposure to sunlight. This happens particularly after a day at the beach or similar other outdoor activities. This may cause you some discomfort while you adjust to the new surroundings. Although this is a temporary condition, you should be fine in a few minutes – in case the bright rays of the sun caused damage to your eyes, you’ll need to promptly consult an ophthalmologist.
  • Diabetic retinopathy is a serious condition. People with high blood sugar levels should regularly consult an eye specialist to keep a check on the development of this condition.

Symptoms of night blindness

The first symptom of night vision issues or night blindness is difficulty in seeing things in low-lit areas. This may also include the particular symptoms associated with the cause that has triggered the issue in you. For example, difficulty in viewing things that are far (in case of myopia), cloudy or blurry vision in case of cataracts, and so on.

Diagnosis and treatment of night blindness

If you have been lately finding it difficult to view things clearly in low-light conditions, get your eyes checked for night blindness. While in the initial stage, you can quickly recover from the symptoms – delaying it can definitely be risky.

At the ophthalmologist’s, you’d be tested on the visual acuity parameters besides also physical evaluation of the condition and of your family’s medical history.

Blood tests to measure your glucose levels, vitamin A levels, and other conditions may also be recommended.

Night blindness can be treated via corrective eye glasses or lenses, corrective surgeries and dietary changes. Certain medicines and vitamin supplements may also be recommended to you.

In case this condition is triggered due to retinitis pigmentosa, it may remain untreated.

Coping with night blindness

In case you are struggling with vision issues at night, do not delay seeking medical help. This condition requires immediate medical assistance and timely help can go a long way. Here’re a few things you need to take care of to prevent this condition as well as cope with it in case you’ve already been diagnosed with it:

  • Increase your vitamin A intake and consult your doctor regarding an appropriate zinc dosage
  • Take care of your eyes while you are outdoors
  • Prevent eye injuries
  • Regularly get your eyes tested for an underlying condition
  • In case of history of eye diseases in the family, get yourself tested to prevent contracting the same
  • In case you are already suffering from night vision issues, drive only during the day
  • Take help if you need to go out at night fall
  • Consult an ophthalmologist urgently to restrict the progression of the condition and seek proper treatment
