How can I stop my eye power from increasing? What can I make my child eat to reduce eyesight power? How to decrease or reduce eyesight number? How to reduce eye number? These are some of the most common questions eye doctors get asked.
Is it possible to reduce eyesight number or how to remove eye number? Read more about Lasik eye surgery or read on to understand more about how to reduce eye numbers.
Eye number means your child has to wear glasses or contact lenses. In technical terms, it means your child has a refractive error. Someone having a refractive error means wearing glasses or contact lenses. Vision means how much someone can see with or without glasses. You can improve your vision by wearing glasses, and of course, this vision decreases if you take them out.
The glasses or contact lenses number or, more correctly, the lenses in the spectacle frame can have three types of numbers.
These are :
Let’s look at each of the types of eyesight numbers that one can have in their lenses. In other words, let's try and understand what eyesight number is. Many must have heard the terms nearsightedness or farsightedness. Let's understand what these mean.
Myopia is also called Nearsightedness. This is the most common eyesight number. Refractive error is a more technical name for eyesight power.
People with nearsightedness will have difficulty reading road signs and seeing distant objects. In other words distance, visual acuity is affected. Near is not. You will yet see well for close-up tasks such as reading, mobile phone, and computer use.
Here, lenses have a minus number, and Myopia occurs because the eyeball is longer than normal.
If an eye doctor were to write this glasses number on a prescription, it would look like -0.50DS or -0.75DS or -1.25DS. We wouldn’t write it as -0.50 power of eye or eyesight number. Here DS stands for diopter sphere. DS is the measurement of eyesight number.
This is also known as farsightedness or long-sightedness. Some amount of Farsightedness is normal in younger children. Here the lens is of a plus number. Plus, sight means that the eye is slightly shorter than normal. Despite having plus power eye, children can see things. They may be seeing these things blurred, but they can still see things. Thus, in children, this often goes unnoticed. Some children born with farsightedness have never seen close objects well. They may not be aware that it’s possible to see them better. Also, hyperopic children can sometimes see close objects well by straining their eyes. Thus plus sight means they may complain of headaches, but not blurring. These headaches occur due to them focusing hard to see things.
If an eye doctor were to write this glasses number on a prescription, it would look like +0.50DS or +0.75DS or +1.25DS. We wouldn’t write it as +0.50 power of eye or eyesight number.
Please note that people tend to equate plus numbers of hyperopia with reading glasses. While reading glasses have a plus number, there can be situations where a child who does not need reading glasses specifically still has a plus number. The reading glasses that people usually associate a plus number with are seen in people above 42 years of age because of age-related weakness in the eye muscles.
Astigmatism or Cylindrical number
If you have astigmatism, you will have blurred vision at all distances. One may also complain of eyestrain and headaches. Children also tend to squeeze or ‘squint’ their eyes to see better with astigmatism. An Astigmatism prescription could contain both plus and minus numbers, but along with the numbers, they have an axis written next to it. These eye numbers are also known as cylindrical numbers.
If an eye doctor were to write this glasses number on a prescription, it would look like -0.50DC*180 degrees or -0.75DC*90 degrees or -1.25Dc*110 degrees. We wouldn’t write it as -0.50DC*180 power of eye or eyesight power. Here DC stands for diopter cylinder.
There is something important you should know. These powers are usually seen in both eyes. These eyesight numbers are somewhat similar in both eyes most of the time. Sometimes, these numbers can be very different in each eye. Let's say the left eye has a number of -4.0 Diopter, and the right eye has a number of -0.50 Diopter. In this situation, the person would see with the right eye and may not notice poor vision in the left eye.
When the eyesight powers are different in each eye, it is known as anisometropia. Anisometropia must be ruled out in children for the sake of their vision and eye health. If this is not detected in time, it can lead to what is known as Amblyopia.
Your child’s glasses number can change. Yes, usually this can increase. But it’s not that simple.
As mentioned, the power of the eye can increase. The actual reason why power increases is an increase in the eyeball length. Suppose the eye grows longer, then the glasses number increases.
As mentioned earlier, ‘ How to reduce eye power‘ or ‘How to improve eye number ?’ are the most common questions we get asked. Reducing the eye power or improving the eye number is not something we can control. This increase or decrease happens on its own. Of course, new research says that an increase in the power of the eye can happen due to the following reasons.
Thus, if one wants to improve the eye number or prevent the eye's power from increasing, they have to reduce their iPad use. They also have to increase outdoor play. These two steps will help protect your eyes from an increasing refractive error.
Is it possible to reduce eye power? Well, there is no real way of reducing the eye number. One can, however, get rid of their glasses by undergoing Lasik eye surgery.
You can, however, take steps to decrease the chances of an increase in eye power. These steps will not improve the eye number or decrease eye power. They will only prevent an increase in eye numbers.

These are types of contact lenses, and one wears these while sleeping. These lenses change the shape of the cornea while we are sleeping. This change is temporary. Now, because of this change, when one gets up and removes the contact lens, they can see without glasses. This clear vision would last until the evening. If one wants to remain glass-free, one must wear these contact lenses every night. Not many eye doctors use this form of treatment, but it is still available. This is available at Eye Solutions, and one can read about Orthokeratology.
Individuals usually wear these glasses over 40 years of age. In children, they tend to reduce eye strain when seeing near objects. This reduction in strain decreases the chances of Myopia progression. Now, it’s important to keep in mind that this is a theory, and even though literature does have reports supporting this, these reports are not many.
Because of the pandemic, we all got onto the computer for many more hours in the day. There has been a lot of discussion about these blue light blocking or blue filter glasses. These lenses provide no additional benefit. You can read more about blue-light-blocking glasses.
Many claim that eye exercises can help in reducing eyesight power. Sometimes these eye exercises are referred to as eye yoga. Some even tell you not to wear glasses because they can be addictive. There is, however, no evidence to suggest that eye exercises can reduce eyesight power. We also know that these exercises do not harm your eyes in any way. So, we tell our patients that if they want to try out eye exercises or eye yoga to improve their eyesight, they can go ahead. However, they should not stop wearing their glasses as sometimes it can significantly affect eye health and lead to something known as Amblyopia.
You may think that your child does not have a vision problem. Your toddler may not be old enough to read the eye chart, but that shouldn’t stop you from getting his eyes checked. This is where a routine eye check-up becomes important. This is a comprehensive eye examination where both distance vision and near vision are checked. It’s important to get your child a baseline eye evaluation for children early in life from an eye specialist. We recommend an eye exam as early as two months. This is especially true if you have a family history of eye problems or notice anything unusual (like any symptoms below). Since he’s too young to know when something’s wrong with his eyesight or know that he has an eye problem, you have to look for the following symptoms.
If your child has any of those symptoms, you should be taking your child to a pediatric ophthalmologist or an eye doctor for a routine eye check-up.
Children need to undergo an eye power test. This pediatric eye exam is slightly different from what we would do for an adult because the patient is a child. The eye power check is slightly different for different age groups.
Babies can see as well as adults regarding focusing ability, colour vision, and depth perception by six months to 2 years. To assess whether your baby’s eyes are developing normally, your eye doctor will use the following tests :
“Fixate and follow” testing determines whether your baby’s eyes can fixate on and follow an object. The object could be a handheld toy as it moves. Infants should be able to fixate on an object soon after birth and follow an object by the time they are three months old.
Parents find it interesting that preschool children do not need to know how to read to undergo eye tests. This is true even when they are too young or too shy to verbalize.
Lotus symbol chart for young children is like regular adult charts with letters. Except that they have special symbols instead of letters. These symbols include a kite, house, bell, bird, and star.
This test involves shining a light into the eye to look for the reflection from the back of the eye (retina). This test helps eye doctors determine your child’s eyeglass prescription or eye power.
After putting eye drops in the child’s eye in this test, a confirmed eyesight number is obtained. This is to get the correct and precise spectacle numbers. Dilation usually takes around 20 minutes. Once we dilate to check the eye number, your eye doctor will also examine the retina and the optic nerve.
Most of you want to improve your eyesight. Lasik is prevalent among those who dislike wearing glasses and want vision correction. Please read more about LASIK. Lasik helps in getting rid of glasses. Usually, LASIK is done after 19-20 years of age.
