The Cavision 4 x 4" Circular Polarizer Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions. A circular polarizer differs from a linear polarizer in that it supports full use of a camera's autofocus and auto exposure functions.
This filter measures 4 x 4" / 101.6 x 101.6mm and is constructed from 4mm-thick optical glass.
This filter is designed to be used with 35mm lenses up to 70mm in focal length or that offer an equivalent angle of view depending on the sensor size of the camera.
- Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.
- Arrange and filter directionally polarized light perpendicularly to the reflected light allowing for the absorption of much of the light.
- Lessens haze in distant landscapes and provides more saturated, vivid colors.
- Strongest effect when used at a 90° angle from the sun.
- Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features.
- Constructed from high quality optical glass.

Lashes like Garbo
Size: 0.27 Fl Oz (Pack of 1), Style: Mascara/Lash Primer, Size: 0.27 Fl Oz (Pack of 1), Style: Mascara/Lash Primer
I think this might be my new go to mascara.
I have the teeniest tiniest lashes ever, they are straight and stick out from my eyelids and without mascara I look like I have no lashes so it’s a struggle finding mascaras that make my lashes look lush.
Let me start off by saying that the primer is amazing.
As soon as I put it on my lashes grew over twice in length!
It didn’t clump and separated my lashes like whoa( the clumping with these lash fiber or extra lengthening mascaras is always horrendous so that was a wonderful surprise), it dried in about 20 seconds and then I put on the coal black mascara.
Vavoom ladies!
Instant fabulous lashes.
So far I have experienced zero flaking after wearing for long periods of time , it hasn’t smudged or melted when I’m dancing up a storm or getting my workout on and the length of my lashes is practically miraculous.
It is not cry proof.
It’s super easy to remove and doesn’t tear out any of my eyelashes though, so that’s another plus!
Also, I have celiac disease and a host of other random allergies and am allergic to SO MANY products it’s ridiculous, but luckily I am not allergic to this magic mascara.
I recently discovered that this doesn’t smudge on my bottom lashes either!
I’m almost 40 and I have never found a mascara that didn’t smudge on my bottom lashes. I’m so oily that even waterproof ones didn’t work!
I stopped wearing it on my bottom lashes for anything but photo shoots after 20yrs old because the smudging made me look like an old lady with terrible makeup skills,but now I can once again rock liner on my bottom lashes!
I included a terrible picture ( I hate getting my picture taken!) and tried to crop it so you can get an idea of how amazing this mascara is( look at those lashes practically touching my brow bone!),because I know I always want to actually see the results of people using the product, so hopefully it helps. :-)
Ps: I don’t have mascara on my bottom lashes in the pic as I didn’t discover it was even a possibility for me until I bought a tube for my bestie ( another oily faced queen)and she told me there was no smudging:-O
