The mother has brown eyes, the father as well: who is really clear what color eyes the baby. Or is it? Well, if it were that simple. In fact, however, are the inheritance of eye color and have involved at least three disparate genes, whose exact duties that science has still not completely figured out. Really surprising, because in 1907 she published the Brothers Davenport 1-gene model that was initially described apparently quite accurate, resulting in blue, green and brown eyes, your model assumes that there is a single gene that determines our eye color .

This gene is located in two identical “copies” before the gene structure of father and mother. The presumption of Davenport: There is in each of the two gene copies of either an expression (allele) for brown eyes and an expression for light blue eyes. The mother of an allele for brown and the father has an allele for blue, the child inherits one blue and one brown allele.

Sounds once funny: Does this mean that the junior one blue and one brown eye have? No, that is, fortunately not. For allele which is active, depends on what the dominant characteristic. Law to Davenport: brown eyes are dominant, while blue eyes are recessive. A child with brown-eyed, blue-eyed mother and father and therefore has brown eyes. Later, the blues but can certainly lose their dominance. Only thus could explain the two scientists that are not always black and blue is just brown.

But how is it with people who are green or gray eyes? Exactly here is the Davenport model come into a tailspin. In reality, the inheritance of eye color is brown / green / blue that is determined by much more than just one gene with two forms. Rather, there are characteristics of brown, blue and green eyes, with the dominance of the genes from brown to green to blue decreases.

Moreover, science assumes that there are other genes that influence the various shades of colors. In addition, the editorial staff to produce the chemical melanin pigment is highly complex. Follow the production of the dye must therefore not always the known rules of genetics – and the children therefore do not always have to inherit eye color from their parents or grandparents.

On target
First we need to think about is how many glasses you want to buy. If you want to save money, then the election form must be more selective in the frame so the frame can play in any condition. Can be used at work or for evenings and weekends. If you have more budget, you can choose some of the more variable frames as needed. For example to work, you can use the frame with a conservative style and simple. For the evenings and weekends you can use a thicker frame, with a touch of ultra-modern style, or ultra-feminine style.

Face shape
Face shape plays an important role in determining the appropriate type of frame you. Even with proper selection of frames will not only make you look more stunning but also can help you hide the face of conditions that are less desirable. Here are examples of recommended frame for face shape listed below.

* Face round: frame oval, or rectangular frame straight, a little bigger than your face.
* Face width: oval or round frames with straight lines, in more or less the same size with the face.
* Face triangle: the frame with a large frame with a straight line up or round.
* Oval face: the frame of any type suitable for this type of face.

Skin Color
Facial skin color was also influential in determining the color of the frame. Variety of frame color comes from one of two basic colors of blue (cool) or yellow (warm). Blue base color can be used for bright color. While the basic colors of yellow can be used for this type tend to be dark colored.

Eye color:

Eye color is a second factor that affects the selection frame. The following classification.

* Blue eyes: the color gray frame, blue, or brown.
* Green eyes: green frame color, violet or burgundy.
* Brown eyes: the color of bronze frames, or made from horn.
* Black eyes: the color pink or gold frame.

Hair Color:

If you have black hair / brown can use a black or navy frames. Bule people should avoid gold-colored frame and select the color of bronze. Here are the various types of frames are available in the market:

* Plastic Frame: Frame type is available in various styles and colors. Plastic frame advantage because it has more color combinations are many and varied from one color to the color layer and unique.
* Frame without rim: frame without rims look sophisticated and beautiful. Without rim glasses with lenses cut in soft shapes and soft colors provide the perfect feminine look.
* And many other frames can be adjusted with age, activities, face shape and color of your skin.

Thing to remember:

When choosing frames for your eyes make sure you have enough time for consider your options and to select the appropriate frame.
If you are confused you can invite your friends who you know is always watching his appearance. Last way is you can ask a suitable frame to the optical professional you visit.
