Eyesight is something that we often take for granted, and it is only when we notice our vision changing that we realize how important it is to take care of our eyes. It is quite important then, that we are aware of possible vision changes and how to prevent and adjust to it, especially as we grow older.
Why vision changes occur with age
Changes in vision can start as early as age eleven. At age eleven, vision changes are usually due to your genetic makeup and while it cannot be completely prevented, precautious methods may be taken to avoid exacerbating the situation. Vision changes can continue as an adolescent grows, usually becoming worse until growing ceases to increase at an exponential rate. From then on, vision changes are relatively gradual and slow and remain quite stable until one reaches the age of forty. Our eyes are quite complex and there are multiple reasons why vision can get worse. However, it is safe to say that age is one of the most common causes for changes in vision. Though this does not apply to everyone, it is quite common for people over the age of forty to notice that it might be harder to read things close to them, or to see things far away. Just as any physical activity seems to get more difficult as you age, you will also find that vision changes will be included in this category. For instance, it can be increasingly harder to focus on objects that are near to you after you pass 40 years of age due to a condition called Presbyopia. Presbyopia literally translates to “old man eyes” in Greek – in other words, vision changes takes effect with aging. What essentially happens with Presbyopia is that the lens in your eye hardens and becomes more focused on far away objects at the expense of seeing objects that near to you. Even if you wear contact lenses, chances are that you will need to wear glasses in addition to those, in order to adjust to your constant changes in vision. This is because people who are initially near-sighted are able to see things closer to them rather than farther away, thus this kind of vision changing requires a pair of glasses along with contact lenses. Vision changes happen naturally, and though Presbyopia is not something you can prevent entirely, there are ways in which the transition and adjustment to your vision changes can be as smooth as possible.
How to prevent vision changing
Because vision is such an essential part of our daily lives, it is important that we do everything we can to prevent vision changes. As vision changes are caused primarily by genetic factors, you should first be aware of your family’s health history in regards to vision. In this way you can regulate how necessary and often it is to get your eyes checked and to see how often vision changes occur as you age. Perhaps the most adjustable habit we can adopt to prevent worsening eyesight is to eat the right amount of nutrients and vitamins that will help keep your eyes healthy. In particular, Vitamin A, Vitamin C, and Vitamin E are vital in keeping your eyesight healthy and stable. Keeping a healthy diet will help you to also maintain your weight and can prevent diseases like diabetes that may eventually affect vision as well. Another significant factor that causes vision changes has much to do with the rapid growth of technology of our generation. We spend an immense amount of time staring at some sort of computer or TV screen, which can cause our eyes more strain than is usual. As a result, your eyes may get damaged or experience dryness. To avoid diseases that come with eye strain and vision changing such as Presbyopia, try to get into the habit of looking up from your computer screen every twenty minutes and focusing on objects that are far away from you. This will help to give your eyes a break from the extra stress. Protect your eyes from harmful UV rays as much as possible to prevent eyestrain as well. Additionally, avoid generally harmful activities to your body such as smoking, to avoid direct causes of vision changes.
How to find the right pair of glasses for strong prescription wearers
Although glasses first started out as a simple necessity for people who noticed their vision changing, it has evolved into a timeless accessory that remains in the fashion world. It follows fashion cycles just like fashion items like jeans or bags, and has expanded not only to people who need glasses to see, but also to those who wear them solely as accessories. Those who wear glasses as accessories are able to wear any shape or size of glasses because the lenses are usually made of plastic or polycarbonate that will not cause your eyes to look any different. This freedom allows those who don’t experience vision changing to style their frames without having to think about anything else. Unfortunately for those who wear glasses, they have to take into account the reason they wear glasses in the first place: their changing vision. For people whose imperfect vision is not too serious, the lens thickness is barely noticeable and looks normal. However, the stronger your prescription, the thicker the lens will be in your glasses unless you opt for high index lenses. If you have a strong prescription, try to also avoid glasses with thinner frames, as thin frames expose the width of the lens. In order to best flatter your eyes and face, go for lenses that have a shorter height on your face. These tend to be more rectangular shapes, or glasses that are not as wide or long. There is an extremely vast amount of style out there specifically tailored towards those with poor vision and it is guaranteed that you will find one that fits you perfectly.
When to consider getting high index lenses
One of the other solutions to thick lenses is to consider getting thinner high index lenses. People who are subject to vision changing find it increasingly difficult to wear big frames without fully embracing the “coke bottle lens” look. The thickness of these lenses causes your glasses to be heavier and somewhat more inconvenient to wear. High index lenses are able to bend the light that enters your eyes more efficiently and have a significantly thinner lens than normal lenses. Because they are thinner, they tend to be more aesthetically pleasing as they won’t make your eyes look smaller and are much lighter on your face. The stronger your prescription is, the higher the index lens level should be. If you tend to drop your glasses often, high index lenses are made from polycarbonate material, which means they are more sturdy, and shatter-resistant and scratch-resistant. For those experiencing constant changes in their vision, have strong prescriptions, and do not wear contacts often, high index lenses are a worthwhile investment to make.
