Many of the brands we carry as well-recognized within the industry for quality and comfort. Majority of the products originate from Japan or Europe and are fully warrantied by the corresponding manufacturer policies. A diverse range of unique and trend-sensitive designs are available, as well a broad selection of traditional aesthetics which offer our clients with almost any look they have in mind.

If linearly polarized light is incident on a quarter-wave plate at 45° to the optic axis, then the light is divided into two equal electric field components.

Essilor is our primary lens supplier of choice. The French-based company is the world's largest lens manufacturer and the inventor of progressive additional lenses. They have lens-manufacturing facilities all over the world, including Vancouver. Essilor supplies a full range of products, from single vision to their Varilux digital progressive lenses with complimentary coating options.

IgM molecules are, by far, the largest of the molecules, which keeps them inside blood vessels. They clump together cells bearing antigens (e.g., bacteria) in a process called agglutination. Peak IgM production takes place in the initial response to an antigen, before the peak IgG production; IgM production drops off faster than does IgG.

Our sunglasses manufacturers primarily work with specific technology to optimise fit and vision in both clear and overcast environments. Brands such as Maui Jim and Zeal both have custom-fit measurements, along with digital compensation to help eliminate prismatic distortion for high-curvature lenses that many sunglasses have. For complex prescriptions or mounting lenses into an eyeglass of your choice, we primarily use Essilor and their line of Xperio polarised lenses, much like Maui Jim and Zeal, offer base curve compensation to minimise distortion in lenses.

The Kids & Teens package from Essilor has an extended warranty for prescription changes, up to 15 months from the date of original purchase. This warranty covers a 1-time replacement for the original lenses, for those that qualify and have purchased the package (from ages 0 to 15 years).

IgE is the key to the inflammatory response. Much like IgA, it is associated with secretions rather than circulating in blood; it occurs in the respiratory and intestinal tracts.

This is the most common immunoglobin protein, with a long half-life. It is present both inside and outside of blood vessels, and is likely to have a role against blood-borne pathogens. It activates complement.

Transitions Gen 8 – this lens is clear indoors, darkening to your preferred grey or brown option when UV rays come into contact with the lens. As windshields have a built-in UV-filter, conventional Transitions will not reach their darkest in the car.

Structurally, they have two heavy and two light chains, and, depending on the specific immunoglobin, additional polypeptide chains. They can stay as single proteins, or polymerize into more complex structures.

Manufacturer of CaF2 optics: custom and stock CaF2 window. Calcium Fluoride windows at very competitive price. VUV grade Calcium Fluoride windows.

Receptors for IgG are on some lymphocytes, monocytes, polymorphonuclear neutrophils, and tissue macrophages of the spleen and liver. The latter are sometimes called part of the reticuloendothelial system.

Immunoglobulins are proteins produced by, and active in, the immune system.[1] They are produced by B-lymphocytes, from the effects of both genes and antigens. Immunoglobulins are responsible for humoral immunity, or immune reactions controlled by antibody molecules in the body.[2]

Xperio - Essilor’s brand of custom-made polarised lenses, these lenses offer reduction of glare in sunglasses. This option is especially recommended for those looking to get prescription glasses with heavy usage by bodies of water or reflective snow-related conditions

In Sight Optical is dedicated to providing the best lenses for optimal vision quality. While we source majority of new glasses to the Essilor lab for finishing and fitting, we can expedite lenses-only cutting/mounting within our facility lab. Scheduling to drop off your glasses for lens replacement can be as short as an hour-wait.

The second most common of the immunoglobulins, IgA is produced by lymphoid tissue lining the gastrointestinal, genitourinary, and respiratory tracts. When secreted, they combine with another protein, secretory component, which help its transport into secretions and protect it from proteolytic enzymes in those secretions.

Crizal anti-reflective coatings – originally developed to allow for greater light transmission through lenses for better the vision, they now offer a greater degree of scratch resistance and hydrophobicity than materials without them. Cosmetically, the coatings provide a clearer appearance of the lenses as they reduce reflected light in all situations, notably in flash photography. A variety of anti-reflective coatings are available with options such as blue-light reduction and anti-static properties.

They are divided into major classes based on the amino acid sequencing of their heavy chains. The classic way to separate the major classes is electrophoresis,[3] although much more complex methods are used to recognize specific antibodies. All immunoglobulins are part of the gamma (γ) globulin class, so they are abbreviated either IgX or γX, where X is a class type. The classes can be separated by a second electrophoresis.

Transitions XtrActive - holds a slight tint indoors and darkens in the car, as this lens will activate with less UV ray exposure than conventional Transitions lenses.

Of these proteins, the role of IgD is least understood. It appears to be associated with the creation of additional circulating B-lymphocytes, and as a surface receptor on lymphocytes rather than as a circulating antibody produced by lymphocytes. If so, it is acting as a cytokine rather than an antibody.

The transmembrane forms become antigen receptors on the B-cells. When activated, the B-cells secrete immunoglobins as antibodies.

Field of View = Field Number (FN) ÷ Objective Magnification · Field of View = 20mm / 10 = 2.0 mm.

We carry an assortment of youth eyewear in the Lower Mainland including pediatric-specific brands such as NanoVista and Superflex; other adolescent-oriented collections of recognizable brands such as Nike, Converse, and Puma are also available.

Majority of our lenses come with a industry standard 2-year warranty for any defects or minor wear-and-tear. This excludes any user-related negligence or loss of glasses.
