How Can I solve Photophobia?

Photophobia

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.

Contact Lenses Firmness

Contact Lenses FirmnessQUESTION

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.

Different-Coloured Eyes

Different-coloured Eyes

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.

Strabismus, Hypermetropia and Contact Lenses

strabismus and contact lensesQUESTION
A patient asked if it is possible for a person suffering from strabismus and hypermetropia to wear contact lenses instead of glasses?
ANSWER
A patient suffering from hypermetropia and strabismus can wear contact lenses instead of glasses, provided that:
the contact lenses are able to meet the psychological conditions they need to adapt (this is the optician’s duty)
the correction prescribed for the glasses do not comprise the use of prisms; in which case this kind of correction cannot be carried out by contact lenses.
FINAL CONSIDERATION
In any case, the situation is quite complicate and must be dealt with by one’s optometrist and optician as well.
As far as cost is concerned, it is not particularly expensive since they are ordinary lenses.

Luxury Eyewear with the Label “Made-in-China”

Friday, February 12th, 2010

Made-in-China eyewear

THE QUESTION

The customer’s doubt is legitimate: why can the same model have two different origins? Is it “normal” or is there a fraud?
Our clients ask often how it is possible that, given a certain luxury item, it may have two different manufacturing proveniences.
A client, in particular, states that he bought the same well-known Rayban model in two different shops and one item was characterized by the label ‘Made in Italy’, while the other was ‘made in China’.

THE ANSWER

To answer the above-mentioned question, it is sufficient to tell a brief history of Ray Ban eyewear.

-In the beginning, Ray Ban’s owner was Bausch & Lomb

-Later, such brand was purchased by Luxottica, which started manufacturing it in Italy (this is the reason for the label “made in Italy”).

-During the last years, it seems that Luxottica brands (Ray Ban included) have been produced not only in Italy, but also in China (that’s why the label “made in China”)

FINAL CONSIDERATION

Unless the brand is faked (which is possible), a pair of glasses coming from China is absolutely “normal”.

New Prescription Glasses: I cannot see well!

Tuesday, February 2nd, 2010

how to adapt to new prescription glassesTHE FACT

It is not uncommon that something like this may occur:

  • The patient has “old glasses” thanks to which he sees very well with both eyes. For some reasons he has to replace these glasses.
  • The patient has also contact lenses with which he reaches a “good vision” with both eyes.
  • The patient states that he has some troubles with the new glasses (he does not see “anything” with the left eye).

At this point the patient addresses the optician who made the new glasses to “understand” the cause of the problem.

So far, nothing extraordinary; three are the possible causes:

1.The lens is faulty

2.The lens is “wrong”; which means that its characteristics are not appropriate for the problem in question.

3.The lens is right but it is not properly fitted (and this is the most likely cause).

THE SOLUTION

In all of the cases, it is the optician’s duty (as far as he is serious and professionally correct) to change the lens in question FREE OF CHARGE and put the patient in the best possible conditions.

THE OPTICIAN’S ANSWER

What left us taken aback is the optician’s answer: “…you got accustomed to a wrong lens, now you will have to get accustomed to the new lens…!!!!!”.

OUR CONSIDERATIONS

To us, this answer is weird; this “gentleman” should only replace that lens and stop telling stupid things, as well as apologize with the patient.
Moreover, we would like to congratulate with this patient, who carried out a research study which might have “enlightened” the optician’s mind; we would prefer to think that the answer stemmed from ignorance rather than from a willingness to deceive (also economically) the patient.

OUR ADVICE

We suggest this patient address to one of the many professionally correct and technically prepared opticians he can find in Italy.

Eyesight is a Precious Asset 2-2

Thursday, January 28th, 2010

A neglected problem: eye fatigue
More than 1/3 of Italians (37%) answer that their eyes often get tired, while only 27% state that they have never had problems on this account.
Despite this, only 9% has considered specific protective lenses. The criteria when choosing eyewear seem to be above all “lightness” and “design” (respectively 26% and 24%). The general impression we receive is that eye fatigue is not considered a pathological problem, but more a natural phenomenon which is dealt with generically by resting.
Poorly informed consumers
On the subject of lenses, however, 26% do not know what lenses their eyewear have, 23% are aware of AR coatings, 10% of the fact that lenses may be plastic and only 6% know about photochromic lenses.
When separating men and women, lens lightness is important for both, while AR seems more important for men, and infrangibility for women. Lightness is however the most determining objective feature for overall choice of eyewear (frame + lens) and is underlined by 26% of interviewees; the advice of experts -ophthalmologists (39%) or optician/optometrists (26%) is also important. The other criteria guiding choice are design (24%), which counts more than price (19%), while infrangibility is down to 13%.
Fashion as a reason for purchase
Fashion seems to be an impetus mainly guiding the choice of a frame but not that of eyewear as a whole. There is therefore a need to constantly inform consumers and also sensitize them on aspects more connected to eye protection and health, such as the adoption of suitable lenses to individual needs and lifestyles.
Little is done to protect children
As far as children are concerned, most parents (66%) state that they protect their children’s eyes (49% in the 5-8 age group; 52% in the 9-13 age group). Lastly, 17% of parents do not adopt any measures to protect the eyesight of their children. In reality, it seems that as long as they are young -i.e. more or less until they are 13 – the best protection against UVA rays is a hat!
More information, more education to prevention and protection
As already emerged in Phase 1, the research study carried out by IPSOS for Transitions Optical highlighted a fairly superficial attention by the Italian public to problems linked to eyesight, an inadequate adoption of measures to protect it and, even more, an endemic lack of information and “culture of visual wellbeing”.
This sounds like a pressing invitation to the industry, trade association and eye specialists – oculists and optician-optometrists first of all – to strengthen their commitment toward greater information, sensitization and education of the public on such crucial issues for the lives of all.

Can Blind People Imagine Colours?

Saturday, January 23rd, 2010

The vision and/or perception of coloursTHE QUESTION:

Sometimes we are asked questions to which it is really hard to give an answer: how does a blind person perceive reality?

THE ANSWER

The answer to this question is basically a philosophical one, we can only say a little about visual perception from the point of view of the traditional optics.
Since this patient has never had any “visual experience”, he will never be able to represent “reality” as a sighted person does. It is possible that shapes and colors may have a “sense” to him/her, but surely not the one we mean. To better understand (maybe) what we are saying, it may help to think about this question: how can I communicate the “concept” of a colour to a person who has never seen it?

Eyesight is a Precious Asset 1-2

Monday, January 18th, 2010

Eyesight is an inestimable, precious asset. And yet, Italians do not seem to be aware of it and, above all, be particularly careful about protecting their eyes. Transitions Optical made a research interviewing 1000 persons on the phone.
In Italy there has been a growing awareness of the importance of health and physical fitness to ensure a high quality of life. This trend does not seem to have involved the eyes and sight, as it is demonstrated by a research study carried out by IPSOS Health for Transitions Optical, a world leader in photochromic lenses. The international study, conducted in successive phases, each of which dealing with specific themes, at this stage involved four European Countries: Germany, Italy, Portugal and Spain.
In Italy the results show that around 48% of the population, i.e. 5 Italians in 10, wears spectacles or contact lenses, an important datum although 41% of the interviewees state that they have no problems with eyesight. Those who mention them place myopia in first place (31%), followed by astigmatism (14%) and, in third place, presbyopia (9%). The first part of the research (published in May 2007) also revealed the lack of concern for the effect of solar rays on the eyes. Consequently, the study underlined that as many as 16% of the interviewees do not use any protection or aid to protect their eyes during exposure to the sun. Moreover, a worrying 37% had expressed the erroneous conviction that damage to the eyes is reversible.
Let’s concentrate on the second stage of the study, made public last October.
Eyesight protection is in third place. Only 39% of Italians (36% men and 42% women) consider that maintaining the efficiency of their eyesight is considered halfway between the very important and the unimportant ones, thus revealing a worrying situation of lack of information and sensitivity to the problem.
There is a surprising persistence of certain prejudices concerning eyesight in the minds of the Italians. For example, 7 Italians out of 10 are ignorant of the fact that as much as 80% of the quantities of UVA rays we are exposed to during our lives takes place before the age of 18, or as many as 62% of Italians consider that people with dark eyes have fewer problems regarding exposure to sunlight! Just out of curiosity, we may add that 20% of Italians think that sunglasses may “damage” the eyes, a fact that probably has to do with many low-cost products, without warranty brands, purchased in the street, on stalls or the beach.

Contact Lenses to Highlight Eye Colour

Wednesday, January 13th, 2010

How to highlight eye colour
QUESTION

In which way can contact lenses interfere with the eye natural colour?

ANSWER

Just because lenses are NOT TINTED, they do not have any effect on the eye colour. Two brief notifications:

  • since contact lenses can enhance the light reflection, they may give the impression that iris is brightest.
  • if the lens edge coincides with iris edge, then it may seem that more emphasis is given to iris, but it’s just an impression.
