1 – Understand basic eye measurements
When you enter the world of visual correction, it may seem like you are entering a world of complex numbers and terms. However, behind these measurements lie key elements that play a vital role in determining the vision correction you need. To better understand this process, let's take a closer look at the basic eye measurements taken during an eye exam.
The sphere: the basis of the correction
The measurement of the sphere is one of the key elements of a visual prescription. It indicates whether you have myopia (difficulty seeing at a distance), hyperopia (difficulty seeing up close) or if your vision is normal. Expressed in diopters (D), the sphere can be positive (for hyperopia) or negative (for myopia). A prescription with zero spherical value usually means normal vision, no correction needed.
The Cylinder and the Axis: Managing Astigmatism
Astigmatism is a common condition where the curvature of the cornea or lens is not uniform, causing distorted vision. The cylinder and axis are crucial measurements for treating astigmatism. The cylinder indicates the power of the correction necessary to correct astigmatism, while the axis indicates the direction of astigmatism, measured in degrees. These two measures work together to provide you with clear, undistorted vision.
The Complete Prescription: Combination of Sphere, Cylinder and Axis
The complete prescription results from the combination of the sphere, the cylinder and the axis. For example, a prescription might be noted as -2.00 -1.50 x 180. This indicates myopia of -2.00 diopters, with astigmatism of -1.50 diopters in a 180 degree axis. The complete prescription reflects the unique complexity of your vision and guides the manufacture of eyeglass lenses or contact lenses that will allow you to see clearly.
The power of addition (add): correction of presbyopia
As we age, many people experience difficulty seeing up close, known as presbyopia. The addition power, expressed in diopters, is used to correct this problem. It is added to the prescription for distance to improve near vision. The power of addition varies according to individual needs and the degree of presbyopia.
By understanding these fundamental eye measurements, you are better equipped to interpret your vision prescription and understand how it affects your vision. The next part of this article will explore in depth the most common vision disorders: myopia, hyperopia and astigmatism, as well as the corrective solutions available for each of them.
2 – Myopia, hypermetropia, astigmatism: demystification of vision disorders
Vision is a miracle of nature, but it can sometimes play tricks on us. Common visual disturbances such as myopia, hyperopia and astigmatism can impair our ability to see the world clearly. Understanding these conditions is key to making informed decisions about correcting your vision. Let's explore these troubles in depth.
Myopia: when distance vision becomes blurred
Myopia, also called myopia or near vision, is one of the most common visual disorders. People with myopia see near objects clearly, but far objects become blurry. This is due to the elongated shape of the eye or the excessive curvature of the cornea, which causes the light to focus in front of the retina instead of focusing directly on it. Glasses or contact lenses with negative (minus) correction are used to shift the focal point to the retina and improve distance vision.
Hyperopia: the challenges of near sight
Hyperopia, often called hyperopia or far vision, occurs when the eye is too short or the cornea has insufficient curvature. This causes light to focus behind the retina instead of directly on it, making nearby objects blurry. People with farsightedness can sometimes compensate for this disorder by contracting their eye muscles to focus, which can lead to eyestrain. Glasses or contact lenses with positive (plus) correction are used to shift the focal point on the retina and improve near vision.
Astigmatism: complex visual distortion
astigmatism is a condition where the irregular shape of the cornea or lens causes visual distortion. Instead of possessing uniform curvature, the cornea or lens has uneven curvature in different directions, which can cause blurred or distorted vision at all distances. Astigmatism can occur in combination with nearsightedness or farsightedness. Glasses or contact lenses with a cylindrical correction and a specific axis are used to correct astigmatism and provide clear, undistorted vision.
By understanding these vision disorders, you can better identify symptoms that could indicate a visual problem and seek appropriate correction. In the next section, we'll explore key considerations for choosing between glasses and contact lenses based on your prescription and lifestyle.
3 – Choosing between glasses and contact lenses
Once you understand the intricacies of your vision correction, it's time to decide which correction solution is best for you : glasses or contact lenses. Each of these options has unique benefits and may be better suited to your lifestyle, preferences, and prescription specifics. Let's explore the key factors to consider when making this decision.
Glasses: style and simplicity
Glasses are a popular choice when it comes to vision correction, and for good reason. They're easy to put on and take off, require less maintenance than contact lenses, and can be a fashion accessory that reflects your personal style. The glasses also offer protection against ultraviolet rays and blue light, which can be particularly useful if you spend a lot of time in front of screens.
However, the glasses can be more cumbersome in certain situations, such as during intense sports activities. They can also create unwanted reflections in certain lighting conditions and can fog up with temperature changes.
Contact lenses: freedom and discretion
Contact lenses provide vision correction without hampering your outward appearance. They offer a more natural field of vision and are not affected by rain, snow or lighting issues like eyewear can be. Contact lenses are especially beneficial for active people, athletes, and those who prefer a rimless look.
However, contact lenses do require a certain level of care and hygiene, with daily cleaning routines and strict adherence to replacement recommendations. Some people may also find contact lens insertion and removal uncomfortable at first.
Make the informed decision
The choice between glasses and contact lenses depends on several factors, including your level of comfort with the interview, your daily activities, your sensitivity to visual constraints and your aesthetic preferences. It can also be useful to have both options on hand to vary depending on the situation.
To make an informed decision, it is advisable to discuss your needs with an eye health professional. They can guide you based on your prescription, lifestyle and individual preferences, helping you to choose the correction solution that suits you best.

THE blue light blocking glasses filter out this harmful light emitted by screens, reducing eye strain, headaches and sleep disturbances. Whether you work on a computer all day or spend time on your smartphone, these lenses can improve your visual comfort.
Progressive lenses: harmonious multifocal vision
The progressive lenses, also known as multifocal lenses, provide a smooth transition between different corrections for near, intermediate and distance vision. Unlike bifocal lenses, progressive lenses eliminate the visible line between the different corrective zones. This allows for a more natural viewing experience without abrupt visual interruptions, providing an elegant solution for those requiring multifocal correction.
Photochromic lenses: adapt to changing light
The photochromic lenses, also called adaptive lenses, adjust their tint based on the amount of surrounding light. They get darker in full sun and lighten indoors. This technology is ideal for those who frequently spend time outdoors and indoors, providing protection against UV rays while adapting to variations in light.
Advanced customization options
Today, lens manufacturers offer advanced customization options to meet the specific needs of each individual. Of the custom glasses are made taking into account factors such as face shape, eyewear wearing position and even visual habits.
