Eyewear Type 

You may know us for our reading glasses, but we also offer other types of eyewear catering to various needs. 

Reading Glasses 

Foster Grant reading glasses deliver on style, quality, and function – all within an affordable price range. Whether you're seeking reading glasses for men, reading glasses for women, or unisex styles, you'll find it all in our reading glasses collection (available in up to +3.50 power on select styles). 

Blue Light 

Our blue light glasses are designed to help filter blue-violet light*. Here, you will find blue light glasses with no lens magnification and those that have your selected magnification throughout the lens. We also offer bifocal-style blue light readers that have a magnified section at the bottom of the lens and blue light Multi Focus™ readers that feature three different reading strengths in one lens. 

SunReaders® 

Switching between sunglasses and reading glasses when doing up-close tasks outdoors can be cumbersome and inconvenient. But you can have the best of both worlds with our SunReaders collection, which combines sunglasses and readers in one. Every pair offers 100% UVA-UVB protection, with options available in fully magnified and bifocal lenses for easier reading of small print. 

Sunglasses 

Looking for the perfect pair of sunglasses? Look no further than Foster Grant! Our extensive collection features a variety of stylish and affordable options for both men and women. Our sunglass lenses have 100% UVA-UVB lens protection and are scratch-resistant. 

 

We also offer Fits Over and ClipOn styles as an affordable sunglass solution that works with your daily eyewear. The Fits Over styles can be worn alone or over your prescription glasses, while ClipOns attach to your existing prescription glasses or readers. Also called Solar Shield® Fits Over sunglasses and ClipOns, both styles feature polarized lenses to reduce glare, provide 100% UVA-UVB lens protection, and are scratch- and impact-resistant. 

Frame Shape 

Selecting the right frame shape for your reading glasses and sunglasses is important for both comfort and style. Our frames are available in a variety of shapes:  

 

  • Aviator – A thin metal frame and timeless teardrop lens are hallmarks of a classic aviator-style frame. 

  • Cat Eye – These iconic frames are called “cat eye” because their oval shape and upswept outer corners mimic the shape of a cat’s eyes.  

  • Club – Club frames are retro cool. These are characterized by a thicker upper part of the frame and a thinner lower portion. 

  • Geometric – Geometric frames have unexpected shapes and often feature both curved and straight lines.   

  • Oval – Oval-shaped frames are characterized by their curved, elongated shape. They’re often narrower at the bridge and slightly wider at the temples. 

  • Rectangle – These sleek frames, which are wider than they are tall, offer a stylish, timeless look for a variety of face shapes.  

  • Round – The circular shape of round frames gives them a classic, retro look that can be both vintage and modern.  

  • Square – A square frame flatters most faces thanks to the straight horizontal and vertical lines that give this shape its timeless appeal.  

  • Way – You can’t go wrong with distinctive way frames. Their trapezoidal shape offers a look that is both classic and modern. 

  • Wrap – Wrap frames are ideal for our SunReaders and sunglasses because they wrap around the sides of the face, offering further protection from the sun’s ultraviolet rays. 

 

If you’re not sure which frame to choose, use ourvirtual try-on feature to help you pick your perfect pair. 

Frame Style 

Along with frame shape, you can also choose your preferred frame style for reading glasses, sunglasses, or SunReaders reading sunglasses: 

 

  • Full frame – A full frame means the lenses are completely surrounded by the frame. This style is durable and is available in metal, plastic, and most frame shapes. 

  • Rimless – Rimless eyeglass frames look nearly invisible. This style offers a minimalist and lightweight option 

  • Semi-Rimless – This style is a combination of full-frame and rimless frames. These frames feature a partial or no frame on the lower section of the lenses and a plastic or metal material on the upper part. 

Frame Colors 

Reading glasses can be a fun accessory you can change to match your mood or style. Our frames are available in an array of colors and patterns, including:  

 

  • Black 

  • Blue 

  • Brown 

  • Clear 

  • Floral 

  • Gold 

  • Gray 

  • Green  

  • Gunmetal 

  • Leopard 

  • Navy 

  • Pink 

  • Purple 

  • Red 

  • Silver 

  • Teal 

  • Tortoise 

Lens Colors 

If you choose SunReaders reading glasses or sunglasses, you can customize them with different lens colors such as blue, brown, gray, green, pink, and yellow. Certain colors can also provide some visual benefits: 

Gray/Smoke 

Gray is the most popular color for sunglasses lenses because it: 

 

  • Provides true color accuracy 

  • Is good for everyday use 

  • Transmits colors evenly 

  • Reduces glare 

Brown/Amber 

Many people choose a brown lens tint because it: 

 

  • Improves contrast 

  • Enhances depth perception 

  • Works well in variable light conditions 

Green  

Is green your color? It could be if you’re looking for good everyday protection and the following features. Green-tinted sun lenses: 

 

  • Reduce glare while brightening shaded areas 

  • Provide good contrast even in low-light conditions 

Yellow 

You may not have considered yellow lenses before. They: 

 

  • Are good in low-light conditions 

  • Improve visibility in foggy or hazy conditions 

  • Polarized 

You can choose polarized lenses forSunReadersreading sunglasses andnon-magnified sunglasses. Polarized lenses have a special coating that filters intense glare from the sun. They’re especially helpful in bright conditions when the sun reflects off surfaces like water, snow, or cement and creates a harsh glare. 

 

Polarized lenses can make it hard to see certain liquid crystal display (LCD) screens, such as on ATMs, smartphones, and car dashboards. These screens are sometimes already polarized and may appear dark if you look at them while wearing glasses with polarized lenses.  

 

We now have a solution to this problem — lenses made with Polarized for Digital technology. These lenses feature reduced lens polarization, which still reduces glare while making it easier to see your cell phone, e-reader, and other digital screens in outdoor environments. Polarized for Digital lenses are available in several of our sunglass options. 

Lens Type 

Our reading glasses are available in many options, so you can find the right pair for your personal style and vision needs.  

Full Magnification/Fully Magnified 

Lenses with full magnification have the selected magnification throughout the entire lens. You may want to choose this lens type if you only wear your reading glasses while doing close-up tasks. 

Bifocal Style 

If you only need glasses to see up close and don’t want to put on and take off your glasses all the time, you may want to try reading bifocals. The top part of the lens is unmagnified so you can still as you normally do at a distance while the reading power is in the bottom portion 

Multi Focus 

In our Multi Focus reading glasses, the bottom third has the highest strength (and the power you choose) for reading. The middle third has an intermediate strength (such as for computer use). The top third has about half the strength of the bottom, for clarity when interacting with someone nearby (sitting across a desk, for example).  

 

The innovative Multi Focus™ lens technology means you don't have to take your readers off and put them back on to see things clearly at various distances.  

Power 

Reading glasses are available in different strengths, also called “diopter” (D) or “reading power.” The strength is written with a plus sign followed by a number, such as +1.25 D. Most over-the-counter reading glasses start at +1.00 D (as the lowest reading strength) and increase in +0.25 increments. Most of our readers go up to +3.25 D, while select lenses are available at +3.50 D. 

 

The strength of lens magnification ranges and should be selected based on the amount of near-vision correction you need. Our strength guide may help you determine what power reading glasses are right for you. However, the best way to determine the strength you need is to visit your eye doctor for an eye exam.  

Unmagnified 

In addition to our wide variety of reading glasses, we also offer various types of glasses and sunglasses without magnification, including: 

 

  • Blue Light Glasses – We offer blue light filtering glasses and sunglasses with no magnification. The patented lens technology filters at least 30% of blue-violet light** while still providing 100% UVA-UVB lens protection. 

  • Traditional sunglasses – Our diverse range of traditional sunglasses combines classic designs with modern lens technology, providing stylish eye protection for your outdoor needs. 

  • Solar Shield Fits Over and ClipOns sunglasses – Fits Over sunglasses are made to wear over your eyeglasses or readers. ClipOns easily attach to your prescription eyeglasses or readers for added convenience. Solar Shield® sunglasses offer polarization and 100% UVA-UVB lens protection. 

  • Driving and night driving glasses – Driving glasses are designed to enhance visibility, improve contrast, and provide a more comfortable visual experience in certain driving conditions. 

Lens Features 

We offer lenses that do much more than protect your eyes and help you see clearly. Some of these additional lens options include: 

 

  • 100% UVA/UVB lens protection – This is the maximum UV protection you can get in a pair of sunglasses. 

  • Anti-fog coating – Anti-fog technology helps prevent condensation from accumulating on the lenses to keep them from fogging up. 

  • Anti-reflective (AR) coating – AR coating increases clarity by reducing reflections. 

  • Blue light filtering – This lens technology helps reduce at least 30% of blue-violet light transmission in the 400-455 nanometer range.**  

  • Computer lenses – A pair of anti-reflective blue light glasses can help keep your eyes comfortable and improve your visual experience by reducing reflections when using your computer. 

  • Driving and night driving lenses – Offering improved contrast for enhanced visual comfort, the back of these scratch- and impact-resistant lenses are treated with anti-reflective coating to help prevent light from bouncing back into the eye. 

  • Gaming lenses – Eye Gear® gaming glasses help filter at least 76% of blue-violet light.* These yellow-tinted lenses also improve contrast when using gaming consoles. 

  • Oleophobic lenses – These lenses have an oleophobic coating that is designed to repel oil (such as from your fingers). Our premium anti-reflective lenses also have an oleophobic coating.  

  • Polarized lenses – Polarized lenses have a specialized filter that reduces glare from reflective surfaces.  

  • Polycarbonate lenses – Also referred to as impact-resistant lenses, polycarbonate lenses are lightweight and shatter-resistant, making them sturdier than traditional plastic lenses. 

  • Scratch-resistant lenses – Many of our glasses and sunglasses feature a coating that creates a harder surface on the lens, making them more durable and resistant to scratches.  

Frame Features 

Your glasses should always fit comfortably. You can choose from numerous frame features to help ensure you find the right fit for your needs: 

 

  • Nose pads – Nose pads are small cushions that help your glasses sit comfortably on your nose. 

  • Adjustable nose pads – Our adjustable nose pads provide a comfortable fit for all-day wear. 

  • BendToFit® temples – These are temples (arms) that let you adjust the temple tips (ends of the arms that wrap around the ears) for a customized fit. 

  • Flex temple – These temples are made of flexible materials, offering comfort and durability. 

  • Folding frame – Our folding Micro-Readers fold perfectly into their own compact case and are ideal for everyday use. 

  • Spring hinges Typically located at the temples, spring hinges allow eyeglass frames to adapt to various face shapes and help ensure a more comfortable fit. 

  • Lighted frame – Lighted frame glasses feature one LED light on each temple that is individually activated with a switch on the inner temple. The batteries for these lights last an average of 50 hours. 

 

The best way to protect your reading glasses is to keep them in a case whenyou’re not wearing them. Most of our reading glasses come with a protective case.  

 

If you need reading glasses, sunglasses, or SunReaders reading sunglasses, take some time to get to know Foster Grant. With our wide variety of options, we’re confident you’ll find your perfect pair.
