Parents of children diagnosed with eye problems at school and prescribed glasses do not immediately accept this. ‘I only got glasses when I was in college. Look at him doctor, he is not eating properly. Some people say that the vegetables never touch anything. He went a step further and said, ‘From now on, I will give all the fruits and make it right. They will say, ‘Don’t need glasses now, doctor.’ Nearsightedness, farsightedness and astigmatism, which are said to require wearing glasses, cannot be corrected by vegetables or eye exercises.
‘Don’t want vegetables? What are you saying, doctor?’ You ask…vegetables, nutritious foods, reducing screen use and eye exercises are all good things. But, Didn’t the ancients say that ‘disease is the first impulse’… The reason behind wearing glasses varies from person to person. Many people have to wear glasses because of the slightly different structure of the eyes. Very few suffer from vision impairment due to general poor health and extreme malnutrition. The most important role in the eye structure is the front-back length of the eyeball.
Like the length, the structure of the iris and retina and some changes in their curvature (Curvature) also need to wear glasses. Just as height, length of fingers, size of ears, size of nose are not the same for each of us, similarly the structure of the eyes is different from one to another. Such small-scale changes are quite normal in nature’s system. These are not common diseases or epidemics. An axial length variation of just one millimeter requires a lens of 3.00 diopters. This is 6.00 diopters of glass required per millimeter variation in curvature. The length of the eyeball is slightly longer in the problem called myopia. A concave lens is used to correct this. Patients with hypermetropia need a convex lens. Cylindrical lenses are fitted for astigmatism.
People who don’t wear glasses until the age of 40 also have difficulty reading after that. This condition called presbyopia can also be corrected with convex lenses. Some people have a difference in both axial length and curvature, so both types of lenses need to be given together. ‘Well, I put glasses on, now my vision is better and I don’t get headaches. But why do you tell me to come for a check-up every year?’ The glasses are perfect for me. Isn’t it enough to use that ticket to buy glasses at the store or online?’ You might think that. Aren’t the arms, legs and fingers varying in length as the child grows? The development of the eyes is similar. Due to this, the amount we fix on the lens of the glasses also varies. An annual examination is necessary to detect this. Because the size of the eye is slightly larger in people suffering from myopia, a small hole or crack (Degeneration) may occur in the edges of the eyes, i.e. in the retina. If the water inside the eye enters through these holes, it can cause problems like retinal detachment. These can be detected quickly by regular testing.
These holes can be corrected with a laser before they become serious problems such as retinal detachment. Individuals suffering from diffuse vision should also have their eyes checked periodically for iris defects. Such people may have problems like keratoconus in the iris. Studies have shown that people with nearsightedness are more likely to develop eye pressure. This too can be detected and easily cured during regular check-ups. During a routine eye examination, retinal damage caused by diabetes, certain infectious diseases,
