The other intrusive light form that requires vision protection is blue light. Blue light comes from the sun, but it also comes from devices like your smartphone, computer, tablet, and LED televisions and light bulbs.

To correct this, you’ll need a cylindrical lens. A cylindrical lens has differing refractive powers in each axis, thus making it able to compensate for the difference in refraction in a person’s vertical and horizontal planes and bring the light into one focal point.

To protect your eyes, the solution is blue light-blocking eyewear. Stoggles are injected with a proprietary and state-of-the-art blue light-blocking compound at the time of manufacture, so you never have to worry about a coating wearing off.

The focal length also affects many other aspects of your image, such as perspective and depth of field. To find out more,  see 4 Lens Concepts to Revolutionise Your Photos.

It’s simple enough to get correct vision with the help of prescription lenses, but your eyeglass lenses do more than just work like a magnifying glass. Let’s take a look at how each type of vision correction works.

Focal lengthcamera

If you have nearsighted vision, the shape of your eye is too long. When light enters your eye, it lands just in front of the retina, making it hard to see objects that are far away. Your optometrist will prescribe vision correction in the form of concave lenses. Concave lenses are thinner in the center of the lens and thicken around the edges. This helps route the light rays that enter your eye directly onto the retina.

Blue light can pass through the cornea and reach the retina, just like UV light. We know it can interfere with circadian rhythm and impact sleep, but researchers aren’t yet sure how much additional damage can be done by blue light long term.

A standard or “normal” lens gives a perspective that is very close to that of human vision. Most kit lenses are standard zoom lenses. The popular RF50mm f/1.8 STM “nifty fifty” lens is a standard lens on a full-frame camera, whereas the RF28mm f/2.8 STM is a slightly wider standard lens on an APS-C camera.

Standard Stoggles are crystal clear but still UV protective. If you want Stoggles that throw shade, opt for Sun Polarized Stoggles, which give you a comfortable level of sunshade along with polarization to reduce glare.

Vision problems, also called refractive errors, cause blurry vision, trouble seeing objects close up and far away, and issues with driving at night or seeing double.

Progressive lenses fix that problem by offering lenses that look like single vision correction lenses, with vision correction gradients that blend into one another. You can thank inventors of the 20th century for updating the look and making it possible for us to wear prescription glasses that carry a lot less stigma.

Multifocal lenses (like bifocals and trifocals) have classically been avoided by anyone who can avoid them simply because they have a visible line that makes it easy to tell you’re wearing them… not to mention they look uncool and have become vastly unpopular.

Let’s look at what happens when we shoot at different focal lengths from the same position. Note: For ease of illustration, the angles shown in this article are the horizontal angle of view.

The first line of defense for presbyopia is usually reading glasses. People who suffer from age-related vision loss tend to notice they can’t see their smartphone as well or can’t focus on a book or magazine without pulling it further away from their face.

We’ll explain the four most common vision issues and how your eyeglasses work to correct them. We’ll also explain how new advances in eyewear are working to help you keep your crystal clear vision longer.

These refractive errors are easily corrected with prescription lenses, but understanding how your lenses work is a little more complicated.

Depending on the scene and your intentions, you might not need to go ultra-wide to frame what you want to show perfectly.

Ultra-wide-angle lenses exaggerate perspective so distances between objects look bigger. When combined with the wide field of view, it can bring out a sense of space.

People with hyperopia have eyes that are too short. Because of this, light that enters the eye falls behind the retina, causing images that are close up to become blurry. Your eye doctor will correct your vision with convex lenses, which bend outward.

UV protection should be clearly labeled on the lenses or arms of the eyewear or be obtainable by contacting the manufacturer. Stoggles, for instance, are made from polycarbonate material, which is naturally UV-blocking.

Lenses are classified as wide-angle, standard, or telephoto depending on their focal lengths. Ultra-wide-angle lenses are a subset of wide-angle lenses, whereas medium telephoto and super telephoto lenses are subsets of telephoto lenses.

Notice how the buildings don’t appear to converge towards the top. They would on a wide-angle lens due to perspective exaggeration.

A longer focal length… - Captures less of the scene (= has a narrower angle of view) - Makes distant objects appear bigger (= has a higher magnification)

Any focal length above 135mm full-frame equivalent is considered telephoto. However, 70 to 135mm (full-frame equivalent) is considered short or medium telephoto. These are popular for portrait and product photography due to their natural perspective and comfortable working distance for close-up shots.

If you have an engineering mind, or even if you don’t, you probably find yourself wondering how stuff works from time to time. How does a plane fly, how does a ship float, or how do your glasses magnify your vision so that you can see the words of this article clearly?

Telephoto lenses provide an angle of view that is much narrower than human vision. 70-200mm lenses provide the classic telephoto focal range.

These lenses are thicker in the middle and gradually thin at the edges-the exact opposite of concave lenses. These lenses cause light to focus directly on the retina, instead of behind it.

Safety eyewear wouldn’t really be safety eyewear if it shattered and broke into shards when struck with a flying object. That’s why our eyewear and its design and construction at Stoggles is certified to meet the ANSI Z87.1-2020 standard. This means your eyewear can take a strike or a scrape without harming your eyes.

Your regular eyewear leaves your eyes vulnerable at the sides and top of the lenses. If you were to take a hit or get splashed with a dangerous fluid, you could sustain an eye injury. One solution is to use a wraparound lens. This can work, but sometimes the curvature of the lens can make it impossible to get a prescription lens.

You need a very long focal length to capture a detailed close-up picture of the moon without cropping. The image above was captured at 1600mm using an 800mm lens and a 2x extender.

Stoggles is home to stylish eyewear, and we know style isn’t one size fits all. You can choose from numerous frame shapes and colors to match your own personal style.

The brilliant team at Stoggles can help. While we’re probably not the people to talk to about chemical engineering, we are definitely the ones to help with how your glasses work to correct your vision.

At 16mm, we can capture the entire façade of the fire station as well as the road and the hedge in the foreground. As the focal length increases, details appear bigger in the frame while more of the foreground and the building is cropped out. 200mm gives us a good close-up of the building name and the crests below it.

Focal length

This focal length is measured when the lens is focused to infinity (far into the distance). This is because when the lens is focused to infinity, light rays enter the lens almost parallel. When focused on a nearby subject, they enter the lens at an angle.

Fun fact, the darkness of your lenses has nothing to do with the level of UV protection your eyewear offers. If you purchased your favorite shades at a discount store, be warned: they might not be protecting your eyes from intrusive light.

A shorter focal length… - Captures more of the scene (= has a wider angle of view) - Makes distant objects appear smaller (= has lower magnification)

Getting up close to birds and other wildlife requires a special type of telephoto lens: a super telephoto lens. You may want to combine it with an extender for even further reach.

Safety glasses have been around since the early 1900s, but just like your eyeglasses, they’ve come a long way and have new advancements that make them even more desirable. In fact, the specialized coatings and available filters that safety glasses of today offer make them a necessity for everyone.

Light entering the lens converges (crosses) on its way to the image sensor. This convergence point is known as the optical centre of the lens and has the sharpest focus. The focal length is the distance between this convergence point and the image sensor.

Due to physics, a lens with a shorter focal length has a wider angle of view, and one with a longer focal length has a narrower angle of view. And that’s how we came to use focal length to describe the angle of view of a lens!

You need corrective lenses to keep your vision sharp, and you need safety eyewear to keep your vision safe. Stoggles makes it easy to do both, and look great too.

If you’ve ever felt personally victimized by fogging eyewear, we feel you. When we created Stoggles, we knew it was something we wanted to tackle, so we coat every pair of Stoggles with anti-fogging compound. No anti-fog solution is permanent, but the anti-fog coating we use lasts so long that you’ll forget what fogging glasses look like.

An astigmatism is an issue that involves the shape of your cornea. The cornea in a normal eye is shaped like a basketball. In a person with astigmatism, the cornea is elongated and shaped more like a football. This causes light that enters the eye to be focused in different directions instead of directly on the cornea.

When you look straight ahead with your bare eyes, the field of view in focus is around 50° to 60°. Wide-angle lenses are any lens that gives a field of view wider than that. Ultra-wide-angle lenses are a special kind of wide-angle lens.

Once readers become a nuisance, you’ll want to invest in progressive lenses, the upgraded version of Benjamin Franklin’s invention, bifocals. Progressive lenses offer a lens that is split into two parts. One part corrects vision close up, the other part corrects vision at a distance. With bifocal lenses, you only need one pair of eyeglasses to correct multiple refractive errors.

We usually describe a lens by its focal length. What does it refer to and how does it affect your images? Find out in this article.

The Stoggles solution is to use side and top shields. These shields are low profile in design and won’t interfere with a vision correction prescription if you need one, but they still provide the coverage and function of regular safety eyewear.

When picking a lens, one of the first things you must decide on is the focal length or focal range that you want. This is because the focal length describes the angle of view, i.e., it tells how much of the scene in front of you the lens can capture.

Once you have that eye exam and receive your vision correction prescription, head over to the Stoggles website and upload your script. We’ll outfit you in a pair of Stoggles customized with your specific prescription so you can keep your eyes safe, your vision corrected, and your style on point simultaneously.

Ultra-wide-angle lenses take in so much that they are perfect for capturing grand scenes and large objects that are right in front of you, especially in tight spaces where you cannot move further back.
