Aspheric lenses aren’t just about style. Many people like that they can choose the frames that best suit their face when upgrading to aspherics.

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.

Eyeglasses wearers who have mild prescriptions may not notice a big difference. However, people with strong prescriptions for farsightedness (who usually wear thicker glasses) will experience a significant change.

In the Warm Polarizer filter, Tiffen combines the properties of the polarizing filter with the exclusive effects of the 812® Warming Filter. This valuable filter adds natural warmth to all skin-tones, exterior shade and highlight areas. This is useful in outdoor open shade situations where there is excessive blue in the image and total control over lighting may not be possible.

Because of their spherical curvature, conventional lenses tend to be thicker than aspheric lenses. This makes them thicker and heavier, especially when you have a strong prescription.

With conventional lenses, it’s easy to find affordable frames that match your prescription. Aspherical lenses require more precision to make and take longer to produce. As such, they’re more expensive due to manufacturing costs.

Aspheric lenses have a more complex front surface with a gradual curve. They also perform better by improving the way light refracts onto the retina.

They also have a more attractive profile because there is less curvature. This means they don’t have the same “coke bottle” look as you get with traditional lenses.

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.

Reducing the thickness of the lens offers other benefits. Slimmer lenses give you more options when it comes to choosing frames.

People with higher-order refractive errors, typically +4.00 diopters or more, are ideal candidates for aspheric lenses. The difference between conventional and aspheric lenses is most noticeable for farsighted people.

Conventional lenses are prone to spherical errors (aberrations) that create blurry images. Even slight blurring makes wearing glasses uncomfortable. Aspheric lenses do not have this problem.

Polarizer Filter

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.

Aspheric lenses are flatter than conventional lenses. Although flatter, they still offer the same vision-enhancing benefits.

Conventional lenses have a spherical curvature on the front of the lens (like a basketball). On the other hand, aspheric lenses are smoother and flatter, reducing distortion when wearing glasses.

Aspheric lenses are smoother and flatter, reducing the distortion that occurs when someone wears glasses. For many people, this improvement means feeling better in their glasses. They may be more willing to wear their corrective lenses.

This is no longer the case with aspheric lenses. You can now choose from  various styles and shapes of eyeglasses without sacrificing appearance and comfort.
