A circular polarizing filter absorbs rays of sunlight, by rotating the ring you control the effect. A Circular Polarizer is used on cameras with beam splitting metering systems commonly found on auto focus SLR’s (for most 35mm auto-focus cameras see your camera manual). The Standard Circular Polarizer filter blocks 1.5 stops of light and is one of those must have filters.

How to make your glassesantiglare at home

Polarizing filters provide color and contrast enhancement. Reflected light often shows up as whitish glare that washes out color in an image. A Polarizer filter corrects this problem producing deep, dramatically blue skies. It also removes glare from non-metallic surfaces, such as windows and water. Color saturation in general, especially outdoors, can be improved significantly. Standard Polarizer filters blocks 1.5 stops of light.

Anti-reflective lenses, also known as anti-reflection or AR lenses, go a step further than anti-glare lenses by reducing reflections on the lens surface from both the front and back sides. The lens coatings are made of a microscopic layer of metal oxides that neutralize reflections, allowing them to minimize glare from the front and back surfaces of each lens.

While anti-glare and anti-reflective lens coatings offer improved visual clarity under harsh lighting conditions, anti-reflective lenses minimize distracting reflections on both the front and back of the eyeglass lens. Anti-reflective lenses are worth the investment because they provide maximum protection and visual acuity.

Anti-glare lenses improve contrast, reduce eyestrain and provide clearer vision by allowing more light to pass through the lenses. They enhance visual comfort by minimizing the distracting reflections on the lens surface. With anti-glare coating, you may experience reduced eye strain and find it easier to see in low-light conditions.

Anti-glare lenses are designed to reduce the glare reflecting off your lenses from bright lights, reflections and harsh indoor or outdoor lighting conditions. If glare from sunlight or artificial light sources makes it difficult for you to see, an anti-glare coating can help.

Anti-reflective lenses virtually eliminate reflections, allowing 99.5 per cent of light to reach the eyes, compared to 92 per cent for regular lenses. In addition to providing sharper vision and reducing eye fatigue, AR lenses enhance your eyewear’s cosmetic appearance by reducing lens reflections. They’re especially beneficial for people who work for long hours in front of screens or under intense lighting conditions.

The low light polarizer has less of a polarizing effect than a standard polarizer filter, allowing for it to be used in indoor and darker situations when available light is at a premium. Low light polarizer filters require 1 stop of exposure compensation, instead of the standard 1.5 stop compensation.
