Myopia or nearsightedness is known to occur when the light rays do not focus on the retina, but in front of it due to excess curvature of the cornea and elongated eyeball. This refractive error leads to the formation of blurred images of distant objects. The near vision remains unaffected in myopics. It is a common refractive error and its incidence is increasing with time especially in adolescent children. It has become a health issue concern as it is one of the leading causes of blindness or loss of vision along with other co-morbidities such as cataract, glaucoma, retinal detachment, and macular degeneration. Children who are at risk of developing nearsightedness should be identified early to limit its progress and prevent it from developing into pathological nearsightedness. It is known to run in families and a child whose both parents are myopic is under the risk of developing nearsightedness. They should be evaluated early and treated on time to prevent complications. The symptoms should be identified and regular eye examinations should be done for early identification of the disorder.(1)
What To Eat And Avoid When You Have Nearsightedness?
It is important to maintain a healthy lifestyle for better nourishment of the eyes and maintain good vision. It is important to take a diet rich in vitamins and minerals for the healthy cornea. A diet rich in fish, nuts and green leafy vegetables might help reduce the risk of developing nearsightedness. It is also seen that eye disorders such as glaucoma, cataract or retinal detachment can all be affected by the diet. Fish is the main source of omega-3 fatty acids that help in vision enhancement. Green leafy vegetables provide the body with nutrients such as lutein that provide nourishment to the eyes. The requirement of the body should be met either by diet or by taking supplements to prevent any kind of vitamin deficiency.(2)
Carrots are a rich source of vitamin A that helps in absorbing light passing through the eye and adjusting to low levels of light especially at night. People who consume carrots on a daily basis have a good night vision. It is essential to eat them raw or lightly cooked in oil so that the body finds it easier to absorb the nutrients from them.
Spinach is another food that is rich in lutein and zeaxanthin that prevents macular degeneration and the formation of cataracts. Lutein is known to form pigments in the macula that help in filtering the harmful UV rays that can damage the eye. Age-related macular degeneration can be prevented by the formation of sufficient pigments in the eye. Oranges are rich in vitamin C that helps in approximately 64% reduction in the rate of developing cataracts. Tomatoes and red peppers are also rich in vitamin C and other anti-oxidants that prevent oxidation stress in the body. Dark berries also improve night vision by strengthening the capillaries providing blood and nutrients to the eye. They are rich in anthocyanins that help in preventing loss of vision and formation of cataracts along with macular degeneration.(2)
Other foods that help strengthen vision are beef which is a rich source of zinc. It helps in the release of vitamin A from the liver that helps in strengthening the eye tissues. Zinc deficiency can lead to macular degeneration of the retina and ultimately loss of vision. Almonds are rich in vitamin E that helps protect the eyes from free radical damage from UV rays exposure.(2)
It is also important to avoid smoking as it can lead to corneal drying and ulceration. Exercise of the eyes is important although direct exposure of eyes to sunlight should be avoided s it might lead to damage of the cornea. One must reduce strain on the eyes and wear proper corrective lenses and spectacles to improve eyesight. A regular visit to a doctor is necessary and an added symptom of halos and aura must be addressed to.(1)
