Prescription glasses can help you to see better, but you may not realize that you need them. Sometimes you aren’t aware that your vision is deteriorating, although you may experience headaches, eyestrain and various other symptoms. If you have never had to wear glasses, you may think you will continue not having to wear any, but your vision can change. A vision problem doesn’t just show up one day – it can sneak up on you gradually.
If you notice any changes in your vision, it is worth having an eye test to see whether prescription glasses could sort out your problem. Even if you aren’t having any problems, getting regular eye exams is essential to catch any eye problems early.
- You struggle to see far away objects
If you find that far away objects are blurry, it could be a sign that you need prescription glasses for nearsightedness. Nearsightedness is a common vision problem, and if you’re squinting to try and see objects like street signs, you may be suffering from this problem.
Refraction takes place when the cornea and eye lens bend the light coming into the eye and concentrate it on the retina at the back of the eye. The light may not focus on the retina if your cornea is too curved or your eyeball is too long. This means you can see objects close by clearly, but objects that are further away become blurry.
If you have an eye test and receive a prescription for your glasses, you can buy them online. When you order online, it is possible to get 24 hour prescription glasses right to you delivery address.
- You struggle to see nearby objects
Farsightedness is not as common as nearsightedness, but it is still a fairly common refractive problem.
Farsightedness is the opposite of nearsightedness in that close objects are blurry while objects far away may be quite clear. This happens when the cornea is abnormally shaped, or the eyeball is too short.
If you find that nearby objects are blurry, you may need prescription glasses for farsightedness. The curve of prescription lenses can counter the shape of the cornea or short eyeball that’s causing blurred vision.
- Your vision is fuzzy and wavy
If an eye test shows you have astigmatism, it means light isn’t evenly distributed onto the retina. The front surface of the eye or lens inside the eye isn’t completely round.
When the eyeball is a round ball, the light comes in and blends evenly to give you a clear picture. If the shape of your cornea is more like a football, light bends more in one direction than the other. This means that only part of an image is in focus, and things at a distance may seem blurry and wavy.
People who have mild astigmatism may not be aware they have it, but if it’s serious, prescription glasses can help to correct it. This is a condition that can happen at any age and often occurs along with nearsightedness or farsightedness.
- You can’t see to read properly anymore
As you start to age, your eyes are not as flexible as they were when you were young. This lack of flexibility means that focusing on nearby objects often becomes impaired. This is why many people wear reading glasses when they get older.
Presbyopia is a typical symptom of aging and usually affects people at about the age of 38 and beyond. If you find you need to hold your book at arm’s length to make reading clearer and have blurred vision at normal reading distance, you could have presbyopia. This condition can easily be corrected with reading glasses.
- Your eyes hurt from staring at screens
Staring at a computer screen for hours can cause eye strain and headaches. Digital eye strain is a common complaint today.
You can get prescription lenses that filter out blue light, which will make it easier to fall asleep at night. Too much exposure to blue light, especially just before bedtime, can prevent you from falling asleep.
Special computer glasses are available to help you focus your immediate vision, which is the distance between the computer monitor and your face.
- You get nagging headaches
You can get headaches for many different reasons. However, they could be a sign that your eyes are struggling to focus. Headaches from struggling to focus often occur at the front of your head or around your temples.
If you have constant headaches, one thing you have to check is whether it is caused by your eyes. Having an eye test could indicate that your headaches are happening because of a problem like nearsightedness that is easy to correct by wearing the right prescription glasses. If your eyes aren’t the problem, you can start looking for other possible reasons for your headaches.
