Choose the type of film lights to use on your movie or TV set can be a daunting task, so we created a helpful list of all the lighting types for you!

At last the light reaches its final destination: the retina located at the back of the eye. In a way, the retina is like a movie screen. The focused light is projected onto its flat, smooth surface. However, unlike a movie screen, the retina has many working parts:

This focused light now beams through the center of the eye. Again the light is bathed in moisture, this time in a clear jelly known as the vitreous. Surrounding the vitreous is the tough, fibrous, white part of the eye known as the sclera. It protects the delicate structures inside the eye.

On the other side of the cornea is more moisture. This clear, watery fluid is the aqueous humor. It circulates throughout the front part of the eye and keeps a constant pressure within the eye.

I'm a female with an eye condition called pterygium, or more commonly known as "surfer's eye". I need wrap-around glasses that protect my eyes from UV light. I wanted something not too "clunky" looking and reasonably priced. These fit the bill! I got black but would love to have other colors: aqua and light purple preferably. I've worn them when sitting out in the sun and walking and am very pleased with them. One thing I'd like is a darker lens, even though I know this has nothing to do with the protection...just prefer a darker tint. Still, they are great otherwise. Please keep these in stock and get more colors if possible! :)

Signals sent from the photoreceptors travel along nerve fibers to a nerve bundle at the back of the eye, called the optic nerve. It carries all the information collected from the eye to the brain.

I like these because they get the side of your head so that you don't get any stray light in there. Visibility is good and the carrying pouch is a nice touch.

The first thing light touches when entering the eye is a thin veil of tears that coats the front of the eye. Behind this lubricating moisture is the front of the eye, called the cornea. This clear covering helps to focus the light.

Now light has reflected from an object, entered the eye, been focused, and converted into electro-chemical signals. But seeing hasn’t yet happened. That’s because the eye is only part of the story. Now the brain must receive — and interpret — the eye’s signals. Once this is done, vision occurs.

A silky, second-skin liquid highlighter that creates an instantly dewy, buildable glow while also nourishing skin so it looks on the bright side all day.

After light passes through the aqueous humor, it passes through the iris. This is the colored part of the eye. Depending on how much light there is, the iris may contract or dilate, limiting or increasing the amount of light that gets deeper into the eye. After light flows through the iris it enters the pupil — the black dot in the middle of the eye. The light then goes through the lens. Just like the lens of a camera, the lens of the eye focuses the light. The lens changes shape to focus on light reflecting from near or distant objects.

These amber shooting glasses are commonly used during shooting, hunting, and target practice. Research studies show that contrast of overlying objects are enhanced by the yellow lenses due to selective reduction of short wavelength light. The amber-colored lenses provide a slight detriment in color vision to enhance the contrast when viewing bright objects against a white or blue background (ie: the sky). These lenses also feature superior eye protection against debris, shell casings, and bullet cartridges.

Comfortable, wrap around, reasonably priced, and they fit over my glasses. I can stare directly at a UV bulb without feeling the slightest discomfort, not that you should. Good price, good product. A must have if you use any UV lights.
