Eyeglasses and face shape

Eyeglasses and face shape

When choosing our glasses, we need to keep in mind if we are going to wear them permanently or occasionally (in the office, at the computer, or according to current fashion trends), and we must pay close attention to face features, eyebrow line, hair, skin and eye color. In general, it is advisable that the shape of the frames to have the geometric line opposite to the shape of your face. For example, joining a square frame to a square physiognomy will only accentuate its features. Regardless of the shape of the face, the glasses frames should be chosen so, as when laughing, the cheeks do not lift the frames.

  • Round face: This type of face is best fitted with square or rectangular glasses with a slightly elongated shape, which will create the effect of stretching the face and draw attention to the upper part of it. For wider faces, thin-sunglasses are suited, and for a more delicate physiognomy, thicker frames can be chosen.
  • Square face: is the type of prominent cheekbones and jawbone physiognomy, to which the best fit are rounded or oval frames, to soften the features and draw attention to the forehead and the cheekbones. The type of “aviator” or “biker” glasses is the most appropriate, with small nose brigde to create de effect of smaller nose. An equally good choice would be the frames that do not have the contoured bottom, or rimless frames.
  • The heart-shaped face: the features of this type of face are easily recognizable, the cheekbones and possibly the forehead are more pronounced, and the jaw and chin slightly pronounced as a triangle with the tip down. We recommend eyeglass frames which are thin and round to minimize the wide forehead. The butterfly frame, wider at the bottom, or the rimeless are the right choice.
  • The diamond-shaped face: is a rare form, like a triangle with the tip up. In order not to accentuate the jaw line, are indicated frames with the upper part more pronounced, with raised tips towards the temples, rounded corners, and eventual decorations in the temples area to create a width effect in the temples area and to balance the face features.
  • The oval face: is the most advantageous due to good proportions. It fits all types of glasses frames.

Classification of glasses lenses

Classification of glasses lenses

CLASSIFICATION OF LENSES

  • By material
  • After design
  • Thickness
  • After treatments
  • After use

1. AFTER MATERIAL

  • Mineral Glass (Glass)
  • Organic glass (plastic)
  • Polycarbonate
  • Trivex

1.1. GLASS

  • Recommended for certain activities (welding, high temperatures, smelters, etc.).
  • Cheap, but it breaks easily.
  • It can only be carried on a whole frame.

1.2. PLASTIC

  • lightweight (up to 50% lighter than glass).
  • Not breakable.
  • You can choose any kind of frame

1.3. POLICARBONATE / TRIVEX

  • Resistant to MECHANICAL SHOCK / certain activities: motorcyclists, athletes.
  • Recommended for rimless frames.
  • Do not break and are very lightweight..

2. AFTER DESIGN

  • conventionally
  • personalized

Conventional:

  • Conventional lenses are standard lenses (with curved – spherical surface).

Personalized

  • Custom lenses are lenses with a point-by-point optimized surface that offer superior optical benefits;
  • the flattening of the lens surface increases aesthetically by up to 40% compared to a conventional lens;
  • generous field of view;
  • superior image clarity;
  • image closer to the image of the healthy eye;
  • increased visual comfort.

3. LENSES THICKNESS

Lens thickness = refractive index 
The higher the index of refraction, the thinner the lens is.
The standard index is 1.5 and the thinnest lens has 1.74 (for existing products in Romania).

4. 4. SPECIAL COATINGS

Durification coating: Applies only to plastic lenses and has the role of better protecting the lens against scratches.
Anti-reflective coating: is the treatment that increases the transparency of the lens by eliminating the “window” effect appearing on the lens surface, especially in environments with artificial illumination and / or computer use.

Hair colors, eyes and skin with eyeglasses

The harmony between the colors of the eyes, the skin and the hair with eyeglasses

Eyeglasses have the role of vision correction and also an accessory role. The choice of eyeglasses should be made taking into account the color of the eyes, the skin and the hair, so that the harmony is complete. For a warm skin tones, the color of the glasses should be inspired by the color of fire, namely, bronze, cream, gold, peach, orange, beige. For cold shades-skin tones, the colors must be detached from those of the metals, namely, blue, gray, rose, jade, silver, charcoal, amethyst. For mature skin, in which case the skin begins to lose pigmentation and becomes lighter, the bright shades must be avoided. In this case, the shades of brick-red, red or purple are best suited.

Glasses should be matched with both hair and eyelashes colour, and so, for example, blue or green-eyed blondes can choose rimless glasses, their temples mounted directly on their lenses, thin metal frames, or pale, pastel colors. Brown-haired ladies can opt for photochromic lenses (lenses that darkens in the sun), which can blend marvelously with brown hair and eye shades. Green-eyed people can choose warmer or browner tones for frames. Brunettes should avoid eyeglasses with too thick and black frames that roughen the features, or if they wish, they may accentuate them. Instead, they can choose gold, silver or metallic gray tones.
For the most bold and nonconformist, black frames can complement the outfit, but only if they do not create the impression that they cover the intensity of the look.

Info-guide tips
When choosing eyeglasses, it is better to take into account more what is best fitted for our face features, more than what’s fashionable in that season, especially if the glasses have to be worn permanently.

Keratoconus

WHAT IS KERATOCONUS?

Keratoconus is a degenerative disease of the eyeball characterised by a thinning and deformation of the cornea into a cone shape. The cornea plays an essential role in the mechanism of vision, as it is the first medium through which light rays enter our eyes. Its unevenness deflects the rays away from the eye and vision will be distorted.

The disease can affect one or both eyes in 1 in 1000 people and generally starts in adolescence or after the age of 20. The causes are still unknown. But studies have shown that a combination of environmental factors (such as excessive eye rubbing, allergies), some genetic diseases (such as Down’s syndrome, Marfan syndrome or Ehlers-Danlos syndrome) and a lack of important anchoring fibres that structurally stabilise the cornea can lead to keratoconus.

Early signs of keratoconus are blurred vision and the need for frequent diopter changes. Other symptoms include: increased sensitivity to light, difficulty driving at night, halos and glare around artificial light sources, eye fatigue, headaches. In more severe cases, vision can no longer be corrected with glasses or soft contact lenses. Astigmatism is often present.

For most keratoconus patients, the basic treatment is optical correction with rigid contact lenses. These do not take on the shape of the cornea like soft contact lenses and allow light rays to project more clearly onto the retina. The result is the regaining of visual acuity and slowing of disease progression.

Very useful is corneal crosslinking, indicated to slow or stop the progression of the disease. It is a non-invasive procedure that involves treating the eyes with riboflavin and vitamin B2 drops and exposing the cornea for 15-30 minutes to UV-A rays. The treatment induces natural collagen bonds in the corneal fibres to prevent them from weakening. This phenomenon also occurs naturally as the cornea ages, but the treatment accelerates this process and intensifies it.

The benefits are many:

  • improves corneal qualities (strength, rigidity, biomechanical stability),
  • prevents disease progression and further deterioration of vision,
  • improves the wear of rigid contact lenses,
  • postpones the need for corneal transplantation.

As there are no specific manifestations of the disease and all the symptoms presented can be associated with other eye problems, regular eye check-ups are recommended for a correct diagnosis.

Our advice: Don’t let keratoconus progress to the final stage! Because of the high degree of corneal thinning, surgery becomes more complicated, the healing period longer, the restoration of visual acuity slower.

By intervening in the early stages, up to 98% of visual acuity is restored, while avoiding the possibility of reaching the acute phase of keratoconus, where there is a risk of losing the eye as an organ.
