My niece is in the fifth grade now—a typical and pure primary school student. However, one day when I went to her house to visit her family, she asked a pair of kid’s glasses from me. She said with her lovely tender voice: “Aunt, could you buy me a pair of fashionable kid’s glasses if I get the first place in my class this term?” At first I was took aback by her words. I mean, it was reasonable for her to become the number one in her class because she has got that wisdom and talent, but why she wanted a pair of kid’s glasses. I could hardly understand her because in my eyes children should not raise such requirements. Anyway, she was not near-sighted at all. But she appeared unhappy and said: “Aunt, I know what you are thinking about. You must think that I am too little to wear a pair of kid’s glasses. However, nearly all the other girls have got a pair of fashionable kid’s glasses from their parents or relatives except me. Although we are still young kids, we will hold party or ball this year, so every girl should try her best to decorate herself.” I asked her: “But why do you choose a pair of kid’s glasses? Why not choose cute clothes or other decorations?” She said: “That is because that kid’s glasses are in fashion for us now. Especially, the kid’s glasses bought on one big online eyeglasses store are most favorable among us.” Do you see that? The kids have already chosen the most desirable web in their group. Then I amused her: “Then tell your aunt, why you choose this store instead of the others? What are your standards in choosing the eyeglasses store?” She answered loudly: “In fact, we have made a detailed survey before we made sure it is this store that sells the best kid’s glasses.”

After choosing a pair of kid’s glasses in this store  www.prescriptionglassesonline.net , I finally believed that this store offered the cheapest but best eyeglasses among all the brands in the glasses world.

The cheap glasses range on the internet by manufacturers that are offering such a useful range to their customers with facilitating them in a million ways, can’t ever compromise on their quality because internet is open to everyone, and the websites are accessible to everyone as well. That means that any kind of suggestions, comments or views cannot go unnoticed by the people interested in getting them. Not all the eye wear brands offer cheap glasses on their sites. There are a very few reputed brands that offer such a beneficial package. But it requires proper research initially to find authentic websites like one mentioned above. People can get the low rates glasses from outlets as well, but with the disadvantage of being old and low of quality and yet comparatively more expensive than those found on authentic website online like www.cheapglasses123.com, purchasing them online consumes much lesser time and energy of the customers. There are many search engines also that offer this variety on the web. The customers, just need to check their requirements and then they can get the required size, color, frame and lens of their choice.

The reason to why manufacturers offer cheap glasses on the web is not because they are earning profit by selling low quality material, but because they are not facing the extra costs faced by the people running their physical outlets. Additionally, these people sell their brand name. By selling a latest, perfect quality product at very low rates makes the thing accessible for the low income class also to go for it. In this way, the brand of that product gets much positive word of mouth and fame in a way that attracts not only the low and middle income class, but also the upper class that is smart and wants to save time and yet get good quality eyeglasses with latest trends as well. So everyone is being facilitated by these websites.

Thus, in all the ways they can earn positive word of mouth and good repute. They have the technology that also allows the customer to upload his/her picture and see for themselves what size, style, shape and shade of frame fits them, and has an additional advantage of home delivery with warranties as well.

Before you can choose the lens, you must choose the frames. Each frame suit a different face shape. For example, people with round face should wear angular eyeglass frames to make the face look thinner and longer. People with an oval face will look nice no matter what types of frames they wear. If you have an oblong face, you should wear frames with a higher depth compare to the width. People with base down triangle face can opt for glasses that have heavy accent of color. If you have a base up triangle face, you need to buy frames that have a wider bottom and light colors. If your face have a diamond shape, you can try rimless frames. Oval and cat eye shaped frames are also suitable for diamond shaped face.

If you want to purchase the lens, you need to obtain the prescription from the optometrist. It is important that you understand the jargon of the prescriptions including Sph, Cyl, axis, and add. The sph, also known as sphere refers to the correction of your nearsightedness or farsightedness. The sph value is describes in – or + signs. The value will increase in 0.25 steps, for example, 0.25, 0.50 and etc. The cyl value is used by people that already have a correction value. The axis is the correction value that you need to set. The axis value ranges from 0 – 180.

The prescription glasses store will also request you to enter the papillary distance. The papillary distance is the distance between the center of the left eye pupil and the center of the right eye pupil. Many prescription don’t mention the PD measurement. The optometrist doesn’t include the PD measurement to encourage customers to buy from them. If the prescription doesn’t include the PD measurement, you can take the measurement by yourself. You can have your friend help you to measure the PD distance. Your friend should sit at the same height as you. After that, he should place a ruler between the nose bridge. The ruler should be held upside down. The best PD result is taken by looking at the nose bridge of the person that is placing the ruler between your eyes.

The complete prescription for prescription glasses should include the PD (Pupillary Distance) value, Spherical, Cylindrical, Axis and Add value. And the letter OD and OS respectively means the right eye and the left eye.

Sph- Provides the depth of the focal field in the lens. A negative sign in front of the number, indicates that you’re nearsighted while the positive sign means that you are farsighted.

Cyl and Axis- The two designations may be included if you have an astigmatism. Cyl will describe the amount of correction you need to overcome this, and Axis is the angle at which the correction is placed. Please remember that there is always an Axis entry beside a Cylindrical value.

Add- Add value indicates the strength of the overlay on the lens for reading or the bottom near correction for multi-focal lenses. It is typically the same positive number, for both eyes.

By the way, if “DS” or “SPH” is noted on your prescription, it means that there is no correction needed in the corresponding entry and you may just leave this field blank when ordering your prescription glasses.

PD- PD is is the distance (usually measured in millimeters) between the centers of the pupils in each eye. This measurement is used to accurately center the lenses in the frame that you have selected which will also affect the comfort of wearing prescription glasses and this figure does not expire with age.

Sometimes a prescription will list two numbers in the PD entry, such as PD 65/62. The number 65 is the distance PD while the second number 62 is the “reading” or “near-vision” PD which is used if you are ordering single-vision reading glasses. Occasionally a PD is written as 32/34.5 which are the measurements from the center of the nose to either eye. So the PD should be the sum of the two, 32+34.5=66.5. You can enter this as 66 or 67 since one millimeter difference for the PD value doesn’t make a big deal.

When you order glasses online, in order to make sure you can get the satisfied prescription glasses, please double check the prescription entered in the order form before submitting.

Actually, not all the children need to wear their eye wears all days long, though children who need glasses are either suffered from myopia and hyperopia, the optometrist may suggest some kids to take off their eye wears while they do homework or reading. So, we have two options for kids’ eyeglasses, full-time and part-time ones. An eye doctor may give you some specific instructions of buying proper glasses, usually the functional suggestion. However, some other points are left to you and your child.

Lens thickness needs to be first considered before buying eyeglasses for kids. If your child has a strong prescription, the lenses are likely to be thicker and larger, but here is an important criterion that kids’ eye wears should be as light and small as possible, so, you may need to consider to buy high index lenses, such as 1.57, 1.61 or even 1.67 ones, what’s more, you can have a small size lens to avoid vision distortion and blur towards the edges.

Comfort is another important factor. You may find that eyeglasses frames can slide down their nose easily, especially when they are wearing plastic ones, actually, children don’t have a mature nose bridges as adults, this is the main reason. So, I suggest you can choose soft silicon nose pads for them, as they will release the pressure from the eyeglasses frame, and hold their nose stably. And spring cabled hinges are another choice, they can extend to the behind of children’s ears and wrap them firmly!

Last point is fashion forward, if you let your kids to choose what they love best, they probably tend to avoid anything that is termed as “uncool” , however, you need to give them proper guidance when they are selecting their glasses.
