To keep a clear view of the world for many years and prevent any “failures” in the visual system in time is the dream of many of us. Today, for this purpose, you can adopt dozens of life hacks on the Internet or apply recommendations familiar from childhood. However, the professional community considers some of them to be myths that do not help to protect the eyes and sometimes even harm health. We will consider erroneous ideas about vision and its protection together with Olga Bulgakova, an ophthalmologist, medical consultant at Essilor Academy Russia, an expert of the Crizal brand.
Carrots and blueberries save eyesight
Healthy vision is inextricably linked with a complete, balanced diet, which includes vitamins and nutrients. These include vitamins A, B, lutein, and other essential elements. They are found, among other things, in carrots and blueberries, the healing properties of which many remember from childhood.
Talking about the benefits of these products for saving eyesight is not entirely correct. Firstly, our body is saturated with vitamin A not only from carrots and blueberries. Other foods are involved, such as liver, many fruits, and leafy greens. It turns out that a standard diet, without a focus on specific products, already contains the necessary dose of vitamins. These micro-and macroelements nourish the organs of vision and improve health in general. Secondly, no matter how balanced and varied nutrition is, it will not replace corrective optics or correct visual impairments or pathologies.
Wearing glasses all the time is harmful to your eyes
Belief in such a myth can have dire consequences for vision. The outdated opinion about its deterioration due to glasses has developed for the following reason: corrective optics supposedly allow the eye muscles not to strain. And if they are constantly in a relaxed state, there is a risk of visual impairment.
“In reality, on the contrary, without vision correction, the eye muscles begin to work hard, which leads to overstrain, headaches and other troubles. For example, patients with moderate or high myopia come to ophthalmologists more and more often, and many cases of myopia progression are associated with the stereotype of the “harmfulness” of wearing glasses. In fact, it is not the means of vision correction that have a detrimental effect, but the rejection of them, ”adds Olga Bulgakova.
Flat LCD screens are completely safe for eyesight
Modern LCD screens are improved and are less harmful to the eye’s structures than older models that emit hazardous electromagnetic radiation. But, unfortunately, today’s gadgets also affect eye health if you do not provide reliable vision protection.
Even the latest smartphones, laptops, and other devices, equipped with different “chips” to reduce eye strain, absorb only part of the harmful radiation. Long-term work at close range and a decrease in blinking frequency are added to the negative factors. As a result, eye fatigue syndrome occurs: the clarity of vision decreases, there is a feeling of sand in the eyes, redness, and other symptoms.
You can protect your eyesight from unnecessary stress thanks to special lenses that block the blue light of the screens. With such a mission for 5+ lenses with premium coating, Crizal Prevencia cope provides a clear view of the world without discomfort. Lenses filter dangerous blue light from gadgets using the unique Light Scan technology while transmitting useful blue rays, which are necessary for adjusting the sleep and wake cycles and natural color perception.
Corrective glasses can be replaced with perforated glasses
Training glasses have small holes in the lenses, making the picture clearer by focusing narrow light beams on the retina. This effect gives rise to the misconception that perforated optics are an excellent alternative to prescription glasses. It’s time to debunk this myth. At the moment, the long-term effect of using optics with small holes has not been proven. As soon as the person puts the glasses aside, the visual acuity returns to the same level. In addition, perforated models are not suitable for people with severe visual impairments, including progressive myopia and glaucoma.
