Q: If you want to order glasses that fit from an online boutique or manufacturer, you'll need to know your exact prescription for the lenses. You wouldn't want to order a pair of glasses that you can't see out of because you didn't know your correct prescription.  If you haven't had glasses before, you should go to an optometrist and have a full eye examination so that they can tell you what your prescription is. If you have been to the eye doctor recently, just call them up and ask them for a copy of your prescription. Specific glasses prescriptions are usually good for about one year. After that, you may want to consider having your eyes re-examined so that you're able to order glasses with the correct prescription. For glasses to fit perfectly, you'll need to know what your frame size is. You can find these measurements on your existing glasses (if you like the way they fit) or go in and get measured at a store that sells glasses. On your existing glasses, these measurement numbers can be found either on the temple part of the arms of the glasses or on the bridge that runs across the nose piece. The important measurements (in millimeters) include:   Lens size. This is a two-digit number ranging from 40 – 62.  Bridge size. This is a two-digit number ranging from 14 – 24.  Temple size. This is a three-digit number ranging from 120 – 150. If you don't have any current glasses to find your frame size, or if you can't afford to get measured at the optometrist, you can try to guesstimate what size frames you'll actually need. You can use these measurements as a basis for your estimate. These figures are starting points for total width, which includes the lens width (multiplied by two) added with the bridge width – this equals the full width of the frames across your face:   Small/Narrow face: 125mm – 129mm  Medium face: 130mm – 134mm  Large face: 135mm – 139mm  Wide face: 140mm – 145mm Find a reputable manufacturer or glasses boutique that you want to order from. Spend some time looking around to choose the frames that you want.   To make sure you like the style, you can go to an actual brick-and-mortar store and try on similar styles before you place your online order. Some online optical providers also offer tools that allow you to upload a photo of yourself which they overlay the glasses on so you can virtually see what they would look like on you.
A: Find out your prescription. Figure out your frame size. Guesstimate your frame size. Order your frames online.

Article: If you're keeping your food diary as a way to track calories and get in shape, it makes sense to write down your physical activity, too.   Record the type of activity and time spent doing it.  If you can, also add about how many calories you've burned during that particular exercise. See how your level of exercise affects your hunger level and what you eat.  Make notes whether you've noticed increased hunger overall or if you experience increased hunger immediately after a workout. If you're keeping a food diary to make sure you're getting enough of a certain nutrient, you might want to record the nutrition information for each item. It's easy to find nutrition information for any type of food online and many food journal apps automatically provide this for you.  Examples of nutrients to track include:  Fiber Protein Carbohydrates Iron Vitamin D A food diary can be a motivating tool when you have a goal you want to reach that's related to your diet. Whether you want to lose weight or you're just trying to eat more fruit and vegetables, tracking your progress will inspire you to keep going and show you where there's still room for improvement. Here are a few ways you can track it:  Record your weight. Write it down at the end of each week so you can see how it has fluctuated. Note important milestones. If you successfully eliminated gluten from your diet for a month, note it in your diary. Record how much exercise you can perform. For example, record your progress toward running a 5k. Since you're already writing down everything you eat, why not also write down how much it costs? It's a great way to stay within your food budget for each day, week, and month. You might be surprised when you find out where you tend to spend the most money.  Note how much you spent on each meal. Include meals you make at home as well as the meals you eat out. Look for patterns to determine how much you spend on food each week or month, and find places where you can cut back. It might be helpful to tally up how much you spend on food purchased outside of the home.  For example, you might spend money on an afternoon coffee or lunch out with coworkers.  Over time, these little expenses can add up.

Q: Using a sifter, sift 300 grams (10½ ounces) of icing sugar into a large bowl. This is to break apart any chunks that might have formed in the container, and prevent the icing from getting clumpy when you add water to it. You will need to dissolve your icing sugar with some water so that you can spread it over the fairy cakes. Start by adding two tablespoons of water and mixing it quickly with a fork. You want to end up with a somewhat runny consistency so that you can drizzle it over the fairy cakes. Add more water to make the icing thinner, and more icing sugar to make it thicker. You can make the icing flavoured by adding some lemon juice. Use one part lemon juice and one part water. If the icing becomes too thin, then add more of the sugar. You can leave the white icing as it is, or you can add colour to it to match the theme of your party. Add a few drops of food colouring to the icing and stir. For darker icing, use more food colouring. If the icing becomes too thin, then add a little bit more of the sugar.
A:
Sift the icing sugar into a bowl. Add two to three tablespoons of warm water. Consider adding some flavouring. Consider adding some colouring.
