Blurred vision

How do you know if you need glasses?

Feb 14, 2023 | Glasses

For many people, changes in vision can be gradual and go unnoticed until they become a problem.

Good vision is essential for a high quality of life, but many people experience changes in their vision that may indicate the need for glasses. Regular eye tests are essential for identifying any issues with your vision and addressing them before they become more significant.

Here are some common indications that you need glasses.

Blurry Vision

If you are experiencing blurry vision, it may be a sign that you need glasses. Blurry vision can affect your ability to read, drive or perform other daily activities. It may be caused by near-sightedness, far-sightedness or astigmatism.


Frequent headaches may be an indication that you need glasses. If you experience headaches while reading, watching TV, or using a computer, it may be a sign of eye strain. This is particularly common in people who need glasses for reading or close work.


Short-sightedness, also known as myopia, is a condition in which objects in the distance appear blurry, while objects up close are clearer. If you have difficulty seeing road signs, recognizing faces from a distance, or watching TV from a distance, you may be short-sighted.


Long-sightedness, or hyperopia, is the opposite of short-sightedness. With long-sightedness, you may have difficulty seeing objects up close, while objects in the distance appear clearer. This can cause issues when reading, writing, or working on a computer. If you experience headaches or eye strain when performing tasks up close, this may indicate long-sightedness.

Double Vision

Double vision is a condition in which you see two images of the same object. It may be a sign of a problem with the eye muscles, cornea, or lens. If you experience double vision, you should book an eye test as soon as possible.

Seeing Halos or Glare Around Lights

If you see halos or glare around lights, it may be a sign of cataracts or another eye condition. This can make it difficult to see in low light conditions, such as at night.

Problems with Depth Perception

Problems with depth perception can make it difficult to judge distances accurately. This can be particularly dangerous when driving or operating machinery. If you experience problems with depth perception, you may need glasses or another type of vision correction.

Reduced Night Vision

Reduced night vision can make it difficult to see in low light conditions, such as when driving at night. This may be a sign of an eye disease or another vision problem that can be detected during an eye exam.

Squinting Regularly

If you find yourself squinting regularly to see things clearly, it may be a sign that you need glasses. Squinting can help to temporarily correct vision problems, but it can also cause eye strain and headaches over time. If you are struggling to read or watch TV, it may be a sign that you need glasses. This is particularly common in people who need glasses for reading or close work.

What diseases can be detected in an eye exam?

An eye exam can detect a range of eye diseases and conditions. Early detection of these conditions is crucial for successful treatment and can even prevent vision loss or blindness.

Here are some diseases that an eye exam can detect:

  • Glaucoma
  • Cataract
  • Diabetes
  • High blood pressure
  • Cancer
  • Multiple sclerosis
  • Heart disease
  • Thyroid disorder

During an eye exam, the optometrist will check the health of your eyes, including the retina, optic nerve, and blood vessels, which can reveal any signs of damage or disease. They may also perform additional tests, such as visual field testing or OCT scans, to provide a more in-depth evaluation of your eye health. It’s important to have regular eye exams to ensure your eyes remain healthy and any potential issues are caught early.

The Importance of Regular Eye Tests

Even if you have perfect vision, it’s essential to schedule regular eye exams. Adults should have an eye test at least every two years, while children should have their vision checked at least annually. If you experience any changes in your vision, headaches, or eye strain, you should book an eye test immediately. Ignoring symptoms or neglecting to have an eye exam can lead to further complications and potentially irreversible damage.
