Wearing spectacles or eyeglasses has several functions: the glasses keep harmful UV rays away from your eyes, protect your eyes from possible debris and injury, and are colorful and complementary accessories. However, eyeglasses have a more interesting function, one that you are most probably aware of: they correct vision.

Eyeglasses are commonly worn by people suffering from conditions such as farsightedness, nearsightedness, or astigmatism. This means that these people are wearing corrective lenses to help them see better, or by correcting the refractive errors caused by their eye conditions. The strength of each prescription glasses depends on the severity of the refractive error.

These things being said, have you ever wondered why some people wear glasses, and some don’t? Sometimes refractive errors are caused by genetic factors, while other people damage their eyes through the years, such as by constantly reading in the dark or by staring too much at a computer screen. In some people, their refracted vision would manifest early in life, while most people need glasses when they are above the age of 40.

Given this, it is common for people to worry if they need prescription eyeglasses. Below are the most common symptoms that you need corrective glasses.

• Blurred vision – A common way to see if you have blurred vision is to take out a book or your mobile phone and try to use it as you normally would. If you are having trouble identifying the words or the characters, then you may need to go for an eye checkup.
• Eye strain – This refers to the “tired” feeling you get when you’ve been reading or watching television for a long time. If your eyes constantly feel tired even though you’re reading or in an environment where there is proper lightning, then you should probably see an eye doctor.
• Frequent headaches – A telltale sign that you may need glasses would be frequent headaches. When you cannot see properly, your eye muscles would normally work together to make you squint, which helps you distinguish the object in front of you. Therefore, if your vision is already blurry and you find yourself having too frequent headaches from squinting too much, then set aside time for an eye checkup as soon as you can.
• Being unable to see objects that are either near from you or far from you – This may be indicative that you are either farsighted or nearsighted. If you find that you have to sit at the very front of the class in order to see what the professor is writing on the board, then you can probably benefit from prescription glasses.

There are more symptoms you shouldn’t ignore when it comes to taking care of your eyes. Remember, the sooner you have your eyes checked, the sooner you will be able to see better! You’ll be surprised at how crisp, colorful, and vibrant the world may be once you wear your new eyeglasses. Everything would look clearer, and you would wonder how you survived without it for so long!
