Abstract: glasses are recommended when the degree of myopia exceeds 300 degrees. Because 300 degrees or above is already a medium to high myopia, no matter how blurred your eyes adapt, it will have a certain impact on your life and work. Especially when you travel, you may slow down your response and have potential safety hazards because you can’t see clearly., Myopia can only be seen clearly with glasses, but there are always a group of people around you who have the same degree of myopia as you, but you don’t need to wear glasses, and your eyesight seems to be good. Are some people born with “tolerance” to myopia? If you are short-sighted, your eyesight will be better without glasses?, Naked eyesight ≠ diopter. People who think they have better eyesight without glasses often confuse naked eyesight with myopia., Naked vision is simply the vision measured without glasses., Diopter is simply the degree of your myopia, hyperopia and astigmatism., Many people ask doctors such questions when matching glasses: “my eyesight is 0.6. How many glasses should I wear?”, In fact, this question cannot be answered, because there is no one-to-one correspondence between naked eye vision and diopter. Similarly, two people with myopia of 200 degrees may have different naked eye vision., At the same degree, why don’t others wear glasses?,
myopia can only be seen clearly with glasses, but there are always a group of people around you who have the same degree of myopia as you, but do not need to wear glasses, and their eyesight seems to be good. Are some people born with “tolerance” to myopia? Is myopia better without glasses?
naked eyesight ≠ diopter
people who think they have better eyesight without glasses often confuse naked eyesight with myopia.
naked vision is simply the vision measured without glasses.
diopter is simply the diopter of your myopia, hyperopia and astigmatism.
many people ask doctors such questions when matching glasses: “my eyesight is 0.6. How many glasses should I wear?”
and
in fact, this question cannot be answered, because there is no one-to-one correspondence between naked eye vision and diopter. Similarly, two people with myopia of 200 degrees may have different naked eye vision.
and
are the same. Why don’t others wear glasses?
and
mainly depend on the compensation mechanism of the brain. People with strong compensation may have a slightly better ability to recognize objects under naked eye conditions than ordinary people. However, this situation basically exists only under the condition of low myopia. If the degree of myopia is high, the difference will be very small.
a little nearsighted, do you want to wear glasses?
and
● adults need
and
glasses to see clearly and avoid blurred vision, which will affect the quality of life and work efficiency. If myopia affects life and work, you need glasses. On the contrary, if it does not have a great impact on work and life, I can also accept mild blurred vision. I don’t need glasses or a pair of glasses to use when necessary.
but it is recommended to wear glasses if the degree of myopia exceeds 300 degrees. Because more than 300 degrees is medium and high myopia, no matter how the eyes adapt to blur, it will have a certain impact on life and work. Especially when traveling, the reaction may be slow due to unclear sight, which may lead to potential safety hazards.
moreover, our eyes always tend to get the clearest imaging. When you look at blurred things, even if you don’t feel anything, your eyes are already using adjustment, which may lead to visual fatigue after a long time.
● children’s glasses follow the doctor’s advice.
as teenagers and children are in the development stage, it is particularly important to check glasses scientifically. In case of vision loss, go to a professional eye hospital for medical optometry in time to eliminate the possibility of false myopia. If true myopia occurs, glasses should be fitted under the guidance of a doctor.
and
glasses for teenagers and children are not only to meet the needs of life and learning, but also to avoid blurred vision and aggravate eye fatigue, so as to accelerate the development of myopia.
generally speaking, after mydriatic optometry, those with myopia degree lower than 50 degrees do not need glasses temporarily, and those with myopia degree higher than 100 degrees must have glasses. The specific situation should follow the recommendations of professional ophthalmologists.
