WHAT IS PUPILLARY DISTANCE?

What Should I Know?


What is pupillary distance? Pupillary distance, also known as “PD,” is the distance between your pupils, and the measurement that is necessary to ensure the correct positioning of your lenses within the frame you have chosen. Your PD is essential to making your glasses and important because it greatly affects the way you see comfortably through your lenses.

How do I Obtain my PD?


When you get your eye exam done, your eye care provider will typically measure your PD for you. When asking for a copy of your prescription, you can also ask for your PD. However, only a few states in the U. S. are required by law to provide you with your PD. But not to worry — firmoo.com gives you a step-by-step guide on how to measure your own PD hassle-free, straight from your home or office.
What is a Normal PD Number?Most adults have a PD between 55-65 millimeters. Most kids’ PD’s are between 42-54 millimeters. You may notice two numbers on your prescription — this is perfectly normal and common. If the first number is higher, like 62/59, then the first number is your Distance PD and the second is your Near PD (for reading-only glasses).
If the numbers are smaller, this means you have a monocular PD; therefore, you have two separate numbers for each eye. In the case that you have two of the same numbers such as “31/31,” you can add the two numbers together to get 62 as your PD. The two numbers do not have to be the same; you may also have two numbers like 32/31, which would add to 63.

10 Foods Good For Eyes

10 Foods Good For Eyes

1. Spinach

To improve your eyesight, you must regularly eat spinach along with other green vegetables, such as kale, Swiss chard, turnips, mustard leaves and collard greens.

Spinach contains a lot of nutrients including vitamin A, lutein and zeaxanthin that are good for the eyes. Vitamin A helps protect the cornea, lutein protects the eyes from ultraviolet light and zeaxanthin contributes to visual development.

For maximum benefits, drink a glass of fresh spinach juice on an empty stomach in the morning. You can also enjoy spinach as a side dish, in salads or sautéed.

2. Salmon

Eating salmon regularly can help protect the retina from damage and prevent blindness. Salmon is rich in omega-3 fatty acids, which helps prevent dry eyes. The omega-3 fatty acids also help ward off age-related macular degeneration.

Experts recommend having two servings of salmon a week. Salmon can be consumed in soup, salad or as the main dish. Other cold-water fish that help maintain eye health are sardines, herring, mackerel and tuna.

3. Carrots

Carrots contain a lot of beta-carotene, which is a precursor for vitamin A. Vitamin A prevents night blindness, helps maintain a healthy and clear cornea, and protects the cells in your eyes and throughout your body.

Carrots also contain lutein, which helps increase pigment density in the macula, the oval-shaped yellow spot near the center of the retina. This in turn protects the retina and lowers the risk of macular degeneration. Carrots are also rich in fiber and potassium.

You can eat carrots as a snack or you can make soups, salads or side dishes.

4. Blueberries

Blueberries support healthy eye functioning through their antioxidant, anti-inflammatory, collagen-stabilizing, vasoprotective and rhodopsin-regenerating properties.

Eating blueberries regularly improves vision and strengthens blood vessels in the back of the eyes. Blueberries also contain anthocyanins, which help lower both high blood pressure and inflammation and also prevent blockages in the arteries that feed oxygen to the retina.

Along with blueberries, you must also eat blackberries, mulberries, cranberries and bilberries.

5. Sweet Potato

Sweet potatoes contain a good amount of vitamin A, an essential nutrient for the eyes. Vitamin A improves eyesight and also prevents cataracts, macular degeneration and glaucoma. Vitamin A is also required to solve the problem of dry eyes and protect the eyes from both bacterial and viral infections. Sweet potatoes are also rich in beta-carotene, potassium and fiber.

Sweet potatoes come in about 400 different varieties throughout the year and can be cooked in wide variety of ways such as baked, grilled, fried or boiled.

6. Peppers

For the overall health of your eyes, you must regularly eat a variety of peppers including green, red, yellow, orange, and even purple, brown and black.

Peppers are one of the richest sources of vitamins A and C. While vitamin A helps preserve eyesight, vitamin C protects the eyes against cataracts.

At the same time, peppers are also rich in vitamin B6, lutein, zeaxanthin, beta-carotene and lycopene. All these nutrients are essential for maintaining the overall health of the eyes.

To include peppers in your diet, you can grill, stuff, steam, bake and stir-fry them. You can also eat them raw as a snack or part of a healthy salad plate.

7. Walnuts

Walnuts contain a good amount of omega-3 fatty acids that play an important role in maintaining overall eye health. Also, walnuts contain antioxidants, zinc and vitamin E, which work to combat inflammation and preserve cardiovascular health. Along with walnuts, you can also eat other types of nuts like almonds, hazelnuts, pecans and peanuts.

Eating a handful of walnuts daily can greatly improve the health of your eyes and protect them from many different kinds of vision problems.

8. Avocado

Avocados are also great for your eyes. They contain lutein that helps prevent macular degeneration, cataracts and other age-related eye diseases.

They also contain beta-carotene and vitamins B6, C, and E that are essential to enjoy good eyesight and to protect the eyes from oxidative stress damage leading to poor vision.

You can eat avocado as is or add it to salads, dips, soups or sandwiches.

9. Broccoli

Broccoli contains a good amount of vitamin B2. A deficiency of vitamin B2 can make the eyes highly sensitive to light, which can cause inflammation, blurred vision and ocular fatigue. Vitamin B2 also plays a role in preventing cataracts or delaying their progress.

Broccoli also contains powerful phytochemical antioxidants, such as lutein and zeaxanthin, and vitamin A that are essential for healthy eyesight.

For maximum nutritional benefits, eat the tender broccoli heads raw rather than cooked. They go well in many types of salads and can be enjoyed as a healthy snack with some veggie dip.

10. Strawberries

Strawberries contain a good amount of vitamin C, an antioxidant that the body requires to maintain healthy eyes and keep them free from inflammatory diseases.

The different antioxidants present in strawberries can help ward off eye problems like dryness of the eyes, macular degeneration and vision defects.

Three or more servings of strawberries daily can decrease the possibility of age-related eye issues. You can eat strawberries as a great snack, add them to a bowl of cereal or a fruit salad, or in fruity desserts for a healthy sweet treat.

Extra Large Frame Glasses

July 6th, 2015 by admin No comments »

Extra large frame glasses are suitable for those with large head and high nose bridge. So if you decide to buy a pair of glasses, you need to pick a pair of glasses that flatter you. Before you pick out a pair, it’s important to think about what kind of style works best for your facial features and your lifestyle. Then you can narrow it down by considering what type of lenses you’re looking to get, and then the materials and the special features. If you’re constantly on the go, you might want something with nose pads or rubberized temples to keep your frames in place, or if you want something lightweight, that will reflect what kind of material

What’s more, it’s important to establish an in-person connection with an optician, who can help you choose frames that look good on you. These people are trained to help you not only fill your prescription, but to get to know you, your likes and dislikes. It’s almost like mixing an optical pharmacist with a fashion stylist. Whether you’ve got a round face or a square one, there’s a perfect pair out there for you.

When shopping for glasses frames, whether for prescription or nonprescription, it is really important that you choose one that fits properly. Ideally, the glasses should be wide enough so that the temples, or ‘arms’, go straight back to your ears without putting pressure on the side of your head. That pressure can result in headaches and unsightly dents in your head, and nobody that I know wants dents in their head. Glasses frames should also not be so wide that they slide down your nose all the time. So a typical size might look like “51-19-135″ (lens-bridge-temple) this information is important to opticians but because of the widely different frame styles available, these numbers are fairly meaningless to most eyeglass shoppers. Another way to choose, is to pick a frame size you own, or have tried on that is comfortable for you. Measure the total width of your current eyeglasses in inches. For best accuracy, measure from inside temple to inside temple.

Girls Glasses

July 6th, 2015 by admin No comments »

Girls glasses always are in bright color and fashionable design. When the girls to choose glasses, they always take more factors into consideration than boys. Although you may think it as an annoyance, getting a pair of cool, stylish glasses could be a fun, accessory that pulls a look together. Plus, you’ll have improved eyesight! Whether you’re selecting your first or fifth set of specs, use these tips to make sure you get the right frames for you.

When you go to buy new glasses, wear your hair the way you usually do with a favorite shirt in a neutral color. This will help you focus on your face and how the glasses look on you for an everyday look.

Ask for a second opinion. Your parents can provide their expertise, but you may also want to recruit a friend. And don’t forget to ask the sales person for their expertise. After all, this is their job and they will be familiar with all the options in the store that can work for you.

Select a frame that complements your face shape and your features. If you’ve got an angular face, choose ovals or almonds that will soften your look. If your face is more round, try rectangular frames with crisp, straight lines. Generally the frames should not be wider than the widest part of your face.

Match the top of the frames to your eyebrow; they should follow the same basic arc. If the frames sit below your brow, you might look permanently surprised; above your brow and you’ll give the impression you’re angry or frowning.

Make sure the size and position of the frame’s bridge the little piece that sits on your nose and holds the glasses together helps balance your features.

Make sure it’s a good fit. Your eyes should look out of the center of each lens. The frames should not pinch your nose or leave red marks, and they shouldn’t be so loose that they slide down your nose.

How about color? As far as color is concerned, consider your skin tone. Pick a color that is complementary. Need help figuring out your skin tone? If the veins you notice in your wrists and feet seem greenish, you have warm skin, while mostly blue veins mean you have cool skin! Browns look great with warm skin, as do metals and flashy colors like turquoise. Cool tones do better with grays, silver and muted colors.

Taking the time to try out several pairs to find the best fit for you will be worth your while. This pair has to go with everything you wear for at least a few years! You can even go online to some websites that will let you upload a photo of yourself to virtually “try on” frames to see what looks the best on you! If you follow these tips, and your best judgment, many compliments on your new frames are just around the corner.

cheap sunglasses

July 6th, 2015 by admin No comments »

When it comes to protecting your eyes from damage by bright sunlight, actually, the study shows that there is little difference between cheap sunglasses and expensive ones. It turns out almost any pair of glasses, even cheap or untinted ones will do the trick. A pair of sunglasses seems so simple, it’s two pieces of tinted glasses or plastic in some sort of plastic or metal frame. There are four things that a good pair of cheap sunglasses should do for you.

Sunglasses provide protection from ultraviolet rays in sunlight. UV light damages the cornea and the retina, good cheap sunglasses can eliminate UV rays completely. Sunglasses provide protection from intense light. When the eye receives too much light, it naturally closes the iris. Once it has closed the iris as far as it can, the next step is squinting. If there is still too much light, as there can be when sunlight is reflecting off of snow, the result is damage to the retina. Good sunglasses can block light entering the eyes by as much as 97 percent to avoid damage. Sunglasses provide protection from glare. Certain surfaces, such as water, can reflect a great deal of light, and the bright spots can be distracting or can hide objects. Good cheap sunglasses can completely eliminate this kind of glare using polarization. Sunglasses eliminate specific frequencies of light. Certain frequencies of light can blur vision, and others can enhance contrast. Choosing the right color for your sunglasses lets them work better in specific situations.

When you buy a pair of cheap sunglasses, you need to make sure all of these benefits and these sunglasses can protect your eyes well. It is possible to buy sunglasses for 20 bucks, which will also protect your eyes as much as a pair that costs 300 dollars. Even in countries like Australia, the price of sunglasses does not matter because the country has standards for these sunglasses and they should all be in conformity with the law for the UV standards. In Europe there are no standards yet accepted which should be in conformity with all the sunglasses.

flexon frames

July 6th, 2015 by admin No comments »

Flexon frames are a type of hypoallergenic eyeglasses that are made from lightweight, strong, flexible metal. The titanium-based aluminum frames are estimated to be 25 percent lighter than standard metals. These frames are also corrosion-resistant. Flexon frames rank among the most flexible, and Flexon is sometimes referred to as the memory metal; these frames have the ability to return to their original shape after being bent, twisted or crushed.

In 1988, Marchon launched the first eyewear collection featuring Flexon, a lightweight metal alloy that bounces back to shape when bent, forever changing the world of eyewear. With more than 200 light weight, expertly crafted frames, Flexon frames offer extreme flexibility, comfort, durability and style, making them a perfect fit for every member of your active family. Flexon is ideal for individuals with an active lifestyle seeking, ease, comfort and durability in their eyewear, including on-the-go parents or grandparents and energetic kids. No more trips to the optometrist to adjust bent glasses. Flexon eyewear is worry free and hassle free. Moreover, they are easily to be adjusted.

Put your glasses on and look in the mirror. You will want to know exactly what adjustments need to be made before you get started. If your glasses have a nose pad, adjust that first. This will be the easiest part of the adjustment because that portion is usually held together by screws and not by the resilient aluminum-silicon combination that Flexon is made out of. Be careful not to over-bend the nose pad. You may need to use a tiny screwdriver to remove the pad and make the necessary adjustments. Adjust your Flexon eyeglasses in specific parts. Attempts to shape them at the shaft of the temple and on the nose bridge are futile. The tips of the temples are often not made from the flexible material. Look into a mirror and place the lenses directly in front of your pupils. Take note of whether you need to adjust the piece up or down. Use your fingers to grip the joints and make the adjustments. If this doesn’t work, try with needle-nosed pliers. The design allows you to ensure the tips of the temples are adjustable to rest on your ears. The two most common objectives are to position the center of the lens exactly in front of your pupils or to make the glasses more comfortable. Raise one arm of the glasses at the tip of the temple on one side and lower the other to fix glasses that do not sit evenly. Remember to grip the joint tightly. The manufacturer designed the frame for level ears. Often, people have one ear that is slightly higher than the other, so this is a typical adjustment.

However, be careful not to make infrequent and small adjustments. Flexon glasses have small and thin areas where you can make the adjustments. By forcing the adjustments too much, you can break these joints. Note that the joints can also wear out.

about Classic glasses

July 6th, 2015 by admin No comments »

Classic glasses are characterized by frames that appear timeless and do not follow fashion trends. Themes typically found in men’s classic-style eyewear include minimalistic design elements and more traditional colors. Ovals, rectangles, and rounds are common frame shapes associated with this style. The feature of classic glasses for women are traditional look with bold color or add with accessary elements.

Classic eyewear for men can be identified by the use of architecturally classic lines and shapes that characterize traditionally classic frames. One of these classic shapes are rectangular, bold frame fronts as in the classic Wayfarer. These lines and shapes are timeless and are constantly recycled in fashion lines. Other classic fashion shapes are semi rimless frames like the Clubmasterand rimless frames. Clubmaster frames are a nerdy-chic look and rimless frames are a timeless professional staple. Classic frames typically feature solid, bold colors and textures. Frames are normally tortoise, black, havana, or other neutral colors and textures. Certain brands, such as Ray-Ban and Persol, are also associated with being trend setters of classic, male eyewear. In general, these styles are good for those who are looking to minimize glasses shopping. Classic frames serve as fashion staples for the professional man looking to choose one style that will last year round.

Classic eyewear for women can be easily found by the designs such as cat eye. Characterized by the upwards flare at the outer edges of the frames, this little lift has long been seen as fun, flirty, and just a little sexy. Over the years, cat eye glasses have been made in every color, and the angles have gone from subtle little upsweeps to dramatic points you could practically ski off of. Still, classic black with just a little uptick has reigned supreme year after year, and we don’t see this trend dying down anytime soon. Classic eyeglasses for women are also like tortoise shell glasses. Like the cat eye glasses, tortoise shell or horn-rimmed glasses have never really lost their popularity.

Although this look might not be for everyone, putting a new spin on a classic is a great way to keep it alive for a new generation.

plastic frames for men

July 6th, 2015 by admin No comments »

Plastic frames are characterized as comfortable, lightweight and durable. With the stylish range of men’s eyewear on the market these days, comfort, fit and durability rank high with men when it comes to choosing their eyeglasses. So here are some key areas to check out to make sure the plastic frames for men you choose will be comfortable and fit well.

To ensure that the temples do not dig into the side of your head, make sure the frames are wider enough for your face. The edge of the frames should protrude slightly beyond your face so that the temples do not touch your head as they extend back to your ears. Next, make sure that temples are long enough. Then curve at the end of the temple should extend over the ear without pressing down upon it. The optician can reshape and adjust the curve at the end of the temple when your pick your eyeglasses up, but can’t make the temples shorter or longer, so make sure you select the best length. Also check the nosepiece for comfort and fit. Many glasses have adjustable silicone nose pads that allow your optician to fine-tune the fit. For frames without adjustable nose pads, make sure the fit is secure without pinching the bridge of your nose. When you try on the plastic frames, move your head up and down, bend over and pick up something from the floor and see how well your glasses stay in place. With the properly adjusted nose pads and temples, your glasses should stay in place without pressing on your face.

Plastic frames for men has become much more masculine, with older shapes and sizes being reborn with a modern twist. Larger and bolder eye sizes and plastic frame shapes are in. But be careful not to go too big if you have a small face. The small, John Lennon plastic frame glasses are still around and they still work well with smaller faces. For a younger, hip or retro look, men are also turning to plastic. Lightweight and comfortable, plastic frames come in a wide variety of styles, including thin plastics, bold, black ’50s-style frames and layers of colored plastics laminated together to create a unique effect. Classic shapes in tortoise patterns also are likely to remain in style forever.
