QUESTION

I’ve been told that to calculate the right power of one’s contact lenses we must detract 0,25 diopters to the real one; mine is 1,50 and 2,00, should I choose 1,25 and 1,75 ? Other people told me that this detraction must be considered only when the graduation exceeds 3 diopters.

ANSWER

There is a mathematical formula that correlates the power of contact lenses with that of the lenses of prescription glasses. Such formula is mathematically affected by 2 factors:

• the power of the lens on the glasses
• the distance of the glasses lens from the corneal apex (eye)

This formula suggests that if the power of the lens doesn’t exceed 5,00 diopters, no significant variation occurs on the power of contact lenses.

Therefore, if your powers are 1,50 and 2,00, you can put contact lenses of the same powers; in case the power reduction makes your vision more comfortable, it is probable that the measurement of your graduation was not correct.

Furthermore, nylor models use a titan-steel league called Performance Steel on the front, to give more firmness. The bridge is balancing and two-level adjustable, while the Traction Grip system, on the temple terminals, guarantees a perfect grip under any condition: these two technical tricks complete the characteristics that make Ambition a collection ideal for those who want to live thier prescription frame with dynamism and sportiveness.

QUESTION

After wearing my contact lenses for a while, I have got the feeling that my eyes are becoming dry.

ANSWER

When one senses the unpleasant feeling of “dry eyes”, which leads to reduce the time lenses are worn and to increase the frequency of blinking (eyelid winking), we can reasonably think about different problems:

- real “ocular dryness” (or, as to say, insufficient tears). In order to correctly evaluate this problem, it is necessary a serious medical examination;

- the internal geometry of the lens (inner shape) is not suitable to the patient’s ocular situation. In this case, a visit to the authorized optician of the contact lenses is needed;

- the lens “interefe” with the natural mechanism that controls and stimulates the frequency of the blinking (eyelid winking) and the patient must be “taught” how to restore the normal frequency of the blinking. To this aim, specific exercises exist which the optician must adjust to each single patient.

Captivating design, lively lines, “young” colors: the new Blue Bay eyewear collection shows irresistible models dedicated to the youngest. The new “For dreamers only” collection is made up of acetate sunglasses that draw inspiration from the Sixties, with their playful mood, wide shapes and temples personalized by the Blue Bay logo (mod.Vintage1).
The chromatic range comprises vivacious colors, such as purple/white with purple lenses, red/white with shaded-grey lenses, cream with brown/grey lenses, peach/cream with shaded-brown lenses, in addition to the standard tortoise with shaded-brown lenses and black with shaded-smoke lenses.
Other models in acetate, like Vintage 4, display a Seventies mood, with their unisex shapes and double bridges, for a very glamour look!
On the temples, the Blue Bay logo stands out on “hot” colorations: purple/white, blue/white, milk/blue/azure, light brown/havana, tortoise/havana and black/white.

QUESTION

Many people ask me how to solve photophobia, among them a photophobic girl who recently asked me how to cure it.

She suffered from headache, especially when she couldn’t wear sunglasses.

“I’ve been photophobic from a while. I usually wear dark sunglasses -those which protect from UV rays- but when I can’t use them -in the classroom, for example-, I can’t bear the light and I am not able to concentrate myself. What should I do? Can I recover from photophobia?”

ANSWER

Photophobia is not in itself a phatology, but just a symptom of another situation happening at that moment. I strongly advise you to go to your Oculist and show him your state.

As far as glasses are concerned, I assure you that there are no glasses that can cure photophobia; sunglasses (even though very dark) may help soften the effects of photophobia.

To sum up: you don’t have to find a treatment for photphobia, but for the problem that causes it.

QUESTION

Sometimes it happens that we experience “firmness” problems with contact lenses.

In fact, the lens (either hard or soft) may “shift” from its regular position with eye-winking. Everybody asks the reason why such thing happens, but the answers are really simple.

ANSWERS

1. The lens has not been constructed with the right parameters (this is a manufacturing defect);

2. The lens has been correctly constructed, but it does not fit the eye shape (this is an “adaptation” mistake, so a technical mistake by the Optician).

There are no further reasons that may cause a problem related to the unwanted “shifting” of the lens within the eye.

QUESTION

A young girl realised she has two different coloured eyes, one is blue and one is greenish! Her oculist told her the phenomenon was due to “stained” lens.  The girl enquires about her situation and how she could solve it.

ANSWER

If her annotation refers to iris coloration, it is an ordinary phenomenon (which is called ANISOCORIA). On the contrary, if the diversity of coloration refers to pupils, it is possible that her oculist was right.

To banish all doubts, we advise the patient to visit another expert.

Sense of freedom, desire for cheerfulness and fun. Summer is not only the sunniest season, but also the most colourful one. And fashion seems to give free course to its imagination with shocking matches and bright colours. As for eyewear, bold temples-front matchings dominate, with strong textures and high-impact hues, such as fuchsia or red. For those who don’t like to pass unnoticed and want to give their glances new energy and vitality.
