PVD isn't painful and doesn't usually cause vision loss, though it can potentially lead to complications that do.While PVD and age are the most common causes of flashes and floaters, there are others, too. Some of the less serious causes of floaters and flashes can include:
But first, a note about color. Unlike film, digital sensors record light in monochrome. Because of this, camera sensors use a color filter placed over each pixel which allows the sensor to display colors and accurately represent the scene. The color of each pixel is determined by the frequency of the light wave that passes through the filter.

Sensors are also essential when it comes to choosing the right camera. Manufacturers use different types of sensor technology, and understanding their features is key when selecting equipment that best meets your needs.
Anyone can develop eye floaters and flashes. Nearsightedness and aging are linked to both symptoms, but there are other conditions that could put you at a greater risk of developing them, too. Some risk factors for developing floaters and flashes include:
There are two main kinds of sensors — CCD (charge-coupled device) and CMOS (complementary metal-oxide semiconductor). CCD sensors were used for years in the early days of digital photography, as they offered superior quality to CMOS with better noise control and higher dynamic range. They are still used today in some budget compact and medium format cameras, but they have largely been replaced in the market by CMOS sensors as the technology improved over time. CMOS sensors are the industry standard today, as they work more efficiently than CCD, have better low-light performance, cost less, and work better for high-speed capture.
There are few things as distracting as little specks or bursts of light just in the corner of your vision. Eye floaters and flashes are common annoyances that nearly everyone will experience at some point in their life. While these occurrences are usually a normal part of aging, they can sometimes be a warning sign of a bigger problem. Learn more from the doctors at The EyeDoctors Optometrists about floaters and flashes, causes, and the services and treatment options we provide.
Eye floaters, or vitreous floaters, are tiny specks that appear in your field of vision. These specks can look like zigzags, dark spots, blurry areas or other distracting shapes. While these spots may appear as though they are floating in front of your eye, right on the surface, they develop inside the eye itself. Floaters are made up of tiny fibers of collagen that clump in the clear gel (vitreous humor) that lies between the lens of your eye and the retina. They develop when the collagen in your vitreous humor starts to break down because of nearsightedness or aging. These clumps are usually harmless and will go away with time.
When capturing an image using a film camera, the shutter opens, exposing the film to light. The film would record the light, turning it into a photographic image. So with the switch to digital technology, the role of the film is taken over by a sensor. This guide will break down the differences between various digital camera sensor types and sizes, and explain how they affect your photography.
As you can see, there are quite a few different sensor sizes available. But what does this mean for your photography? In addition to the resolution of your image, sensor size also affects your camera’s low-light capability, image quality, depth of field, and your angle of view. Let’s explore each of these concepts.

In most cases, floaters and flashes are harmless and will go away with time. But it is important to always see your doctor with the onset of new flashes and floaters to rule out the more serious causes. As mentioned above, one of the primary causes of floaters and flashes is PVD, a benign condition that occurs with age. While PVD by itself generally doesn't cause problems, it can lead to more serious complications. One of the most common complications is damage to the retina in the form of detachment, tears or hemorrhaging. Retinal detachment and other retinal damage typically require treatment and surgery to avoid vision loss.If retinal damage occurs because of PVD, you may notice severe vision changes alongside floaters and flashes.

Think about how you will be using your camera and what type of images you want to capture. If you need superior image quality for commercial work, then a full-frame or medium format camera would be best. If you’re just starting out and want something more affordable, then an APS-C or micro four thirds system would be a great choice.
The size of the sensor a camera uses can have a big impact on the quality of your images. The most popular types available today are full frame (or 35mm), APS-C (or crop sensor), and Micro Four Thirds. Here’s an overview of each, plus a few additional sizes and the types of cameras they are used for.

A camera sensor is a silicon-based chip that records light data captured through the lens. Instead of using film to record an image, digital cameras use this sensor to convert data into a digital file.
When choosing the right sensor size for your photography needs, there are several factors to consider. Are you a professional photographer who needs maximum image quality or an amateur who is just starting out and wants something more affordable? Do you need the low-light performance of a full frame sensor or are you more focused on street photography and need the discreet nature of a micro four thirds camera? Do you need the shallow depth of field offered by larger sensors or are you more focused on landscape photography where a wider angle of view is important? Answering these questions will help you decide which sensor size is best for your needs.

At its simplest, a camera sensor is a device that captures light, converting it into an electronic signal. This signal is then processed by the camera to create an image. But what does this mean for you as a photographer? Understanding how sensors work helps you appreciate their importance in creating high-quality images.
Eye flashes, or photopsias, are similar to eye floaters, but instead of seeing a speck, people see a flash of color or light.Like eye floaters, flashes develop in the vitreous humor. As you age, the collagen in your body breaks down more quickly, causing the gel of the vitreous humor to shrink and pull away from the retina. This creates momentary flashes of light.
Are you in the market for a new camera or looking to learn more about the equipment you already own? If so, understanding camera sensors is essential. Even if you’re a seasoned photographer, mastering the basics of sensor technology can help you make better choices when selecting new equipment.

Each sensor consists of millions of light-sensitive pixels, or photosites, which are very small areas made up of a photosensitive material that converts incoming light into electrical signals. The number and size of the pixels on a camera’s sensor determine how much detail is captured when taking a photo. This data is then processed by the camera to create an image.

Occasional floaters and flashes are normal occurrences, and they typically appear and subside quickly. They are sometimes more common early in the morning, while reading or after rubbing your eyes. Frequent floaters and flashes can be a sign of a condition called posterior vitreous detachment (PVD), which is a natural change in the eye. While occasional flashes and floaters are symptoms of the collagen in the vitreous humor breaking down, PVD occurs when this layer of gel actually begins to detach from the retina.
However, this isn't always the case, so it's important to see your eye doctor on a regular basis. Your eye doctor at The EyeDoctors Optometrists will diagnose PVD when it first occurs and know to look for signs of complications during your regular check-ups. In addition, there are multiple other vision problems involving floaters and flashes that could signal a need to see your doctor. If vision loss occurs alongside floaters or flashes, that may indicate a more serious condition.If you experience sudden changes to your vision or multiple symptoms at once, visit your doctor as soon as possible. In the unlikely event that your floaters are caused by a more serious complication like a retinal tear or detachment, you may be a candidate for laser therapy or surgery.
In this comprehensive guide, we’ll demystify the world of camera sensors, starting with the basics and exploring how sensor type and size impact your photography. Read on for tips and guidance that will help you make the right decisions when choosing a new camera.
Phosphenes
If you are experiencing floaters and flashes without serious complications, but they are causing you to have difficulty seeing, removing floaters with laser therapy may be an option for you. Consulting an eye doctor, like at The EyeDoctors Optometrists, will help you determine the risks and benefits of such a procedure. A comprehensive eye exam from The EyeDoctors Optometrists can help identify any causes of floaters and flashes, or any other eye issues you might be experiencing.
