Most people experience some form of sight loss as they age. For many, the magic age is 40. However, many people find they need glasses much earlier due to genetics, excessive computer use, and more. Since sight loss can occur so gradually, many people may not even realize that they have issues with their eyes. If you note any of the following problems in your everyday life, you may need to schedule an eye exam to see if you need glasses.
Signs of vision problems include:
If you frequently have eye fatigue, it may not be due to lack of sleep. Straining your eyes can cause them to feel tired and uncomfortable. Other signs that can accompany eye fatigue are itchy and watery eyes, and a tight feeling behind the eyes.
Blurry vision is one of the first signs that many people notice for vision loss. Signs that you could once read easily are now difficult to make out. You may have to adjust the distance of a book you are holding to focus properly on the text. If your eyes frequently blur when looking at objects near or far away, then it is likely your eyes are starting to fail and you could benefit from prescription glasses.
Another sign of vision problems are frequent headaches. You may note the headaches more after extended sessions of reading, looking at a computer screen, or watching TV. While headaches can be caused by many different things, if you notice them in conjunction with other signs of vision loss, then it is time to schedule an eye exam.
If you squint and strain your eyes to read, this can be a sign of vision problems. Take note of the position of your face while you look at maps, road signs, books, computer screens, and anything else that you look at on a routine basis. If you constantly have to scrunch up your face in some way to focus on the letters, it is likely that your vision is not what it once was.
Halos or eye spots
One less-common sign of failing vision is spots in vision or halos around bright objects. This is often a sign of astigmatism or cataracts in the eyes, and should be checked by an optometrist right away.
If you have to blink repeatedly to focus on objects, this can be a sign of failing vision. Blinking often occurs when switching between two vision points, such as when switching to look at something far away after focusing on a computer screen. Healthy eyes should adjust with minimal blinking, while unhealthy eyes will have to blink longer to change focus.
Generally, it is easy to tell if you should have a new eye exam. If you already have poor vision, most optometrists recommend that you have your eyes checked every year in case of further deterioration. However, if you have never had an eye exam, and suffer from several of the above eye issues, it is likely that you will need to wear glasses.
