Understanding your vision test

What is a vision test?

An eye test is a systematic evaluation of your vision, performed by an ophthalmologist or optician. The primary purpose of an eye test is to assess the strength and sharpness of your vision. In addition, the eye test is used to help identify any eye disorders. It is largely through the use of the eye test that professionals can diagnose common conditions such as nearsightedness, farsightedness, astigmatism, and presbyopia. Although these terms may sound technical, they are simply descriptions of various vision problems that many people experience.

Who should get an eye test?

Everyone should consider regular eye exams, but especially those who belong to certain demographic groups or have certain lifestyle habits. For example:

• Children and young people: Vision is essential for learning, and children should have their vision checked regularly to ensure that vision problems do not hinder their learning.
• Adults over 40: Changes in vision are normal as we age. Regular vision tests can help detect and actively manage these changes in time.
• People who use computers and mobile devices intensively: Prolonged use of these devices can lead to digital eye strain. This is where a blue light filter can help.
• People with diabetes: Diabetes can cause a number of vision problems, including diabetic retinopathy.

How do you prepare for an eye test?

To get accurate results from your eye test, it is important to be properly prepared. First, make sure you are well-rested and avoid activities that can strain your eyes before the test. Second, if you wear glasses or contact lenses, bring them with you to the eye test. Your optician will want to see your current lenses or get information about your contact lenses. Third, if you have any eye irritation, inflammation, or other problems, these should be reported before the test.

What happens during an eye test?

A vision test typically consists of several steps and tests. Here are the most common steps you may go through:

1. Medical history: Your vision can be affected by a number of external factors, including your general health, your age, and your profession.
2. Vision test: This is the most well-known part of a vision test, where you are asked to read a chart with letters of different sizes and placed at different distances.
3. Intraocular pressure measurement: This is an important test that helps detect glaucoma, which is a condition that can cause permanent vision loss if left untreated.
4. Additional tests: If your vision shows signs of potential problems, your optician may decide to perform additional tests to gain a better understanding of your vision health.

What is measured in a vision test?

An eye test measures a number of aspects of your vision. The main purpose is to determine your visual acuity and check if you are suffering from any eye diseases - including the health of your eye muscles, eye pressure.

How are the results of a vision test read?

The results of an eye test can seem complex to the average person, as they contain a variety of medical terms and numbers. Your optician should be able to explain to you what each value and score means and how they affect your vision. For example, the results may indicate your need for lenses, the level of vision correction you may need, and the type of lenses that will serve you best, such as single vision lenses or multi-vision lenses with a progressive lens .

What do the results of your vision test mean for your health?

The results of your vision test are important not only for your vision, but also for your overall health. For example, high intraocular pressure can indicate a risk of glaucoma, while distorted vision in one eye can indicate astigmatism. It can also provide indications of other general health issues, such as diabetes, which can affect the blood vessels in the eyes. Conversely, poor vision results can also be the result of lifestyle factors such as poor sleep habits or excessive use of digital devices.
