There are various causes of visual impairment such as enlargement, injury, diabetes mellitus, etc. but the most common cause of weakness before the age of forty is eye structure. I want to find diversity. You see that Allah Almighty has created a lot of variety in every aspect of it. If there are flowers, they will be colorful, if there are birds, they will be colorful. In the same way, the structure of the eyes does not make them all the same. There is also diversity in it. When a child’s body grows bigger, of course, the eyes also go through developmental process. ۔ Similarly, the horizontal and vertical curves of the cornea of many children differ. In all of these cases, the image formed above the eyelid is blurred [out of focus], making things appear blurred. When it is fixed in different ways, it starts to look clear. In this way we can say that visual impairment is not a disease but it is a variety of nature like we cannot call the discoloration of one’s color a disease. However, when this weakness is first manifested, it varies from person to person.
Nowadays children are seen using very large spectacles. Is the visual impairment in children increasing? What are the measures that can be taken to prevent this weakness?
In fact, the incidence of visual impairment in children has not increased but the awareness of people about diseases has increased. In addition, the education ratio has increased, which has improved the assessment ratio. Previously, many children did not know that their eyesight was weak. However, some of the Qur’an confirms that focusing on proximal objects for long periods of time increases the chances of children losing their eyesight, for example, in memorizing children, in children who constantly play computer games. , And children who watch long programs constantly sitting very close to the TV.
What does it mean that some people think of the lens of a positive number, some of them think of a negative number, while many people think of a number at a certain angle?
The one whose eye is smaller than the standard size can be seen clearly by wearing positive number glasses and the one whose eye is big can be seen clearly by wearing negative number glasses. Those whose corneas differ in their horizontal and vertical spheres are numbered at a certain angle called a cylinder number.
Does regular use of spectacles stop the number one spot or does it continue to grow?
Since spectacles do not eliminate the cause of the disease but only treat the symptoms, it has become a misconception that regular use of spectacles stops the number one spot. The structure of the eye usually changes till the age of 18 years, so the number of spectacles keeps changing till then, even if you use the spectacles as much as you want. There are many other problems that can be caused by not wearing spectacles, but it is absolutely wrong to lose sight or get better. Usually after this age the number stops at one place. As this process continues during childhood, the number of spectacles also keeps changing. That is why the number of children’s spectacles should be checked from time to time so that the number of spectacles should be changed as much as the structure changes. In the same way, after the age of forty, the body usually starts to change again, just like the hair starts to turn white. Or if the first lens did not look right now it may be needed, the number of the first lens starts to change, or the number near and far becomes different. Before, all the work was done through one lens, now it is not done.
What are the problems that come with not using glasses regularly?
It is not clear, for which the eyes have to meditate and strain.
Children’s reading and other performance are affected. Psychological problems arise. Headaches occur in children which are sometimes so severe that vomiting also occurs.
If one eye is much weaker than the other, then the development of the weaker eye is impaired. The brain is unable to absorb the information received from that eye and even the development of that part of the brain is impaired. This condition is called amblyopia. If it is detected before the age of twelve, then almost 100% cure is possible, but later it becomes impossible to cure.
The eye that has this defect becomes squinty in many people. This defect can appear in childhood as well as in old age.
The ability to work is reduced and many people also develop psychological problems.
When to wear glasses? Working near or far?
Any number before the age of forty-four, whether positive, negative, or cylindrical, must be used at all times. Only need for distance or only for near.
Should the near and far spectacles be made together or separately?
It has a lot to do with work and necessity. There are three types of spectacles that work at different distances: bifocal trifocal and multifocal.
Is there any cure for visual impairment other than spectacles?
There are very few people whose vision is impaired for some reason or there is an incurable cause behind it, such as diabetes. However, due to sleep apnea, especially limbal conjuctivitis, it is a type of allergy. Certainly such people benefit from medicine but such people do not even benefit from spectacles. Mayo Pithak or any other prescription has come down. Many people have come that I have been treated. See how much difference it has made? When checked, the number seems to be the same as it used to be, but of course the symptoms are definitely suppressed. Possibly for example laser implantation, phaco operation, phakic IOL, corneal rings fitting inside the cornea. However, it is a fact that the most widely used and tested method is laser.
What changes do laser operations make inside the eye?
Because changing the sphere of the cornea can change its ability to focus light, laser changes the outer surface of the cornea. Depending on the size of the lens, some parts are made more rounded and some parts are made less rounded. As a result of this change, the light reflected from different objects begins to be properly focused on the retina and the eye begins to see clearly without any support [ie lenses or contact lenses etc.]. In the following pictures, the procedure of this operation has been explained.
What are the disadvantages of laser treatment? And what to do?
The results of the treatment are best for a small number, however, if the number is very high, such as sixteen or seventeen, then the method of Phakic IOL is used instead of laser and that too is very successful. Of course, if someone already has a disease in their eyes that cannot be cured permanently, then there can be harms, such as a chronic disease of the cornea, if the cornea is constantly inflamed, etc. This treatment is very useful in healthy eye. As far as risk is concerned, it is a fact that this treatment is very simple and safe. Expensive only because its machines and other accessories are very expensive. That’s the decent thing to do, and it should end there. What does it take? Must be 18 to 40 years old, make a plan, put it first in your priorities and don’t want anything special. It takes ten to fifteen minutes, only two or three days later.
What is phakic IOL and what kind of patients is this operation performed on?
It is also a lens that you can call contact lens and IOL. It is surgically fitted inside the eye, but the natural lens is not removed to fit it. After the operation, the patient has two lenses in the eye, one natural and the other artificial. There are two types of this as shown in the picture below. This lens is best for people who have a very high number of glasses and for whom laser surgery is not suitable.
How to overcome visual impairment?
The eyesight begins to weaken with age and the spectacles become worn. However, it is important to keep your eyes peeled.
This may seem like a daunting task, but it is not. You can improve your eyesight as you age.
Signs of poor eyesight
It is said that precaution is better than cure. When you find the following symptoms in yourself, consult a doctor immediately.
Pain in the eyes
Our eyes act as a lens, which adjusts itself to see objects at different distances. But when you have difficulty seeing things at a distance, the eyes have to work a little harder, which can lead to symptoms such as pain, fatigue, dehydration or dryness.
Having a headache
Pressure or tension in the eyes causes headaches, as the eyes have to work harder to do their job, resulting in pain around the eyes, especially reading a book, working on a computer. Or when looking at a board. When the eyes have to focus on seeing things, the muscles are forced to work harder, which causes headaches. If you are doing something with attention, then take a break of fifteen to thirty seconds.
Slightly closing your eyelids, if you can see clearly, means that your eyesight is deteriorating. Squeezing the eyes helps to see well, but doing so for a long time can make the vision worse, while also causing headaches.
Hard to see in bright light
If the eyes begin to sting in bright light, it means that there is an impairment in vision, because this bright light forces the eyes to shrink, as a result of which they have to work harder.
Reduce screen usage
The duration of use of a phone or computer screen can also affect vision, spending two hours or more in a day staring at a digital screen can lead to digital eye strain. This can lead to redness, itching, dryness, blurring, fatigue and headaches in the eyes. To avoid this, it is important to take a break from using the screen.
Smoking causes vision loss and damage to the optic nerves as we age. In addition, diabetes also causes eye problems.
Keep checking up
For eye health, it is important to make it a habit to get them checked up. With this habit, any kind of vision problem can be easily overcome by catching it at the beginning. If you have frequent headaches, your eyes get tired after reading something, you have to shrink it to see something or you have to read a book close by, it can all be the result of poor eyesight.
Deterioration of nature
Your two eyes form two images, which the brain merges into one, but when the vision of one eye is deteriorating, the image formed in the brain is also not correct, which can make you feel sick. According to experts, in such cases, the brain sees two different images and it is difficult for them to combine them.
Useful foods to sharpen eyesight
Sight is an invaluable blessing of nature, which we can protect by eating the following foods.
Okra contains compounds such as zeaxanthin and lutein, which can be helpful in improving eyesight. Okra also contains high levels of Vitamin C, which is good for eye health.
Eyesight gets weaker with age, but doctors believe that beta carotene helps maintain good eyesight. It is also said that eating foods rich in vitamin C, vitamin E, zinc and copper daily improves eyesight. All of these nutrients are present in apricots, which reduce the risk of blurred vision by 25%.
Carrots contain vitamin A which helps the membranes of the eyes and other parts to function better. Daily use of carrots also improves eyesight.
Lutein is an antioxidant that helps improve eyesight. Cabbage is also rich in vitamin C and beta carotene.
Who doesn’t love to eat fruits? As winter approaches, the urge to eat fruit grows. Fruits such as almonds, walnuts and cashews are high in omega-3 fatty acids. It gives the eyelids the strength to fight off bright light and also helps prevent eye problems that occur with age.
