Reading in low light is really difficult, it’s uncomfortable. In a dim light, eyes tighten, get tired faster, it is more difficult for them to focus on letters, a person begins to blink more often, because of this, dry eyes appear. All these effects are short-lived – they will not continue to bother after you close the book and go to bed, which means that they will not affect further visual acuity. Nevertheless, reading in the dark is not so harmless – it can cause a headache.
As a matter of fact. For many centuries, people read and worked almost in the dark – under the light of candles and kerosene lamps. Did any of them complain of poor eyesight because of this? Unlikely.
In order for reading to bring only pleasure, and your eyes do not get tired, try to read in good light . Adjust the lamp so that it shines directly on the book so that there are no shadows and glare on the page – otherwise it will also make reading difficult.
What can actually spoil your vision is the non-use of sunglasses and smoking . It is worth taking care of your diet: eat foods that contain vitamin C, E, zinc, lutein, zeaxanthin and omega-3s – they are good for the eyes .
Myth: Blueberries and carrots improve eyesight.
As a matter of fact. Back in the Middle Ages, people used blueberries and leaves to treat a variety of diseases – from diarrhea to diabetes. During World War II, British pilots ate blueberry jam, believing it would help them see better in the dark. Today, blueberries are added to countless nutritional supplements – they are sold in dried form, in powders and tablets. Nevertheless, there is no sufficient scientific evidence confirming the effectiveness of blueberries in any disease. At the same time, scientists are interested in research, blueberries contain anthocyanins – antioxidants that have quite a lot of potential in the field of medicine and human health. But so far nothing is clear.
The ophthalmologist Vadim Bondar in his blog also destroys the myth of the miraculous properties of blueberries: “The fact is that the effectiveness of blueberries and its preparations has not been proven for any eye disease. In addition, there is no concrete idea of how blueberries and vitamin complexes with it act in case of eye diseases. ”
All of the above does not in the least cancel the fact that blueberries are rich in useful substances and very (very!) Delicious.
With carrots, things are roughly the same. Yes, vitamin A, which is contained in this root crop, takes part in the work of retinal cells, but its deficiency is a rare condition: a balanced diet satisfies the body’s need for vitamins. So there is no good reason to lean on carrots. Vitamin A is also found in other foods.
It is important to remember: there are no universal ways and means to improve vision. Neither dietary supplements nor folk recipes will help to correct “poor eyesight.” If you began to see worse, then there is a reason. And only a good doctor can figure out what is the matter and prescribe competent treatment.
Perhaps the only advice that can be given is: make sure your diet is varied and includes as many fruits and vegetables as possible (according to some studies, they help slow down the development of cataracts ).
