Although eyeglass lenses may look alike, it is important to know that there are a large number of types and quality.
Our staff will take the time to explain what sets them apart and what suits you best.
Here are some examples :
Single Vision Glasses: they are used to correct myopia, hyperopia or astigmatism for a given distance.
Dual vision glasses: also known as bifocal lenses, these glasses are characterized by an apparent line. They allow to correct both the distant vision and the vision of near, depending on the place from where we look in the glasses.
Progressive lenses: These lenses make a gradual transition between near vision and far vision.
High definition lenses: Thanks to digital technology, manufacturers now offer high-definition (HD) lenses that, by reducing distortion, improve comfort and promote better adaptation. But beware the HD glasses are not all equivalent: Just like TVs, their quality and price can vary considerably. Take the time to ask questions to know the product that is right for you.
Most lenses are made of plastic, polycarbonate or glass. While the plastic combines lightness and good impact resistance, the glass is heavier but resists scratches. This material is, however, less popular than before, particularly because of advances in plastics and their treatments.
Several treatments are offered to improve the performance of glasses:
Slim glasses improve comfort and aesthetics. They are often recommended for strong prescriptions.
Scratch-resistant: this treatment combined with good care helps keep your lenses in excellent condition for longer.
Anti-glare treatment: In addition to improving your visual comfort, this treatment allows those who look at you to better see your pretty eyes.
Smudge-resistant treatment: its name can sometimes be confusing, but this stain-resistant hydrophobic treatment helps to reduce maintenance, for example when wearing glasses in the rain.
Gray color: Gray tint is the most popular color for sunglasses. It offers a uniform transmission throughout the light spectrum. This tint does not change the natural vision of colors.
Yellow color: The yellow tint, known to increase the contrast, is appreciated by many hunters and skiers.
Green color: The green tint, popular with the military offers a transmission curve that is very similar to that of the human eye.
Brown color: The brown tint is often used for sunglasses. This tint has some characteristics of the yellow tint in that it also absorbs blue wavelengths. It offers a vision that highlights the warm colors: perfect to brighten a gray day!
Pink color: The pink hue is used especially in dazzling situations inside. Older people with cataracts or recently operated patients can be more comfortable because of the absorption of ultraviolet rays below 350 nm by the pink. However, an anti-UV treatment has the same effect without having to add a color. Dark pink changes the perception of colors. Pale pink tones are usually preferable.
