Protection of eye health : what practices through out the world and what local specificities?

Date of publication :
10/2014

In 2014, the protection of eye health is a widespread practice worldwide. Yet there are behaviours specific to each country. A major international survey of 7,000 people conducted on four continents – Europe (France, Germany), North America (United States), South America (Brazil) and Asia (China, Japan, India) – revealed the similarities and differences of the various practices.

While eyes have always been seen as a precious asset, they are difficult to preserve throughout a lifetime. With the spectacular advances in ophthalmology in recent decades, it has become easier to improve and maintain one’s eyesight. In fact, far more information about eye health and safety is available than ever before. And in many countries, access to eye care specialists has greatly improved. Yet there are still areas for improvement worldwide because the question remains: at a time when we are bombarded with information, have we all become accustomed to protecting our eyes? What are the most widespread practices in today’s world? And are they evenly spread across all segments of the population? 

To answer these questions, Ipsos conducted a major international survey on the following four continents in 2014 [1] : Europe (France, Germany), North America (United States), South America (Brazil) and Asia (China, Japan, India). In each country, a sample of 1,000 people representative of the national population was surveyed (urban populations in China, India and Brazil). Overall, 7,000 interviews were conducted. In each country, the same indicators were measured, enabling researchers to compare perceptions and habits across different countries. In the end, it appears that protecting eye health is a widespread practice worldwide, but that public education on the issue differs from one country to another. The research supports the need for different communication and targeting strategies to continue improving the public’s well-being and eye health.

On a global scale, two-thirds of individuals take preventive measures to protect their eye health.

Interviewed about what they do to protect their eyesight, 68% of re­spondents said they take at least one preventive measure (see Fig. 1). Notable fact: this figure is comparable across countries. In countries such as China and Brazil, the health habits of the urban middle classes are in­creasingly dovetailing with those of populations in developed countries. There is only one noteworthy exception: in Japan, only 36% of respondents report taking one preven­tive measure.

The two pillars of prevention: sun protection and visiting a vision care specialist

How do people take care of their eyes? Two preventive measures par­ticularly stand out worldwide. The wearing of sunglasses is the first measure. This is a well-established habit among 32% of respondents. Protecting the eyes from sun expo­sure is viewed as a very important health habit. Populations in France and the United States are most likely to be concerned about this issue. In these two countries, nearly one in two indi­viduals reports wearing sunglasses to protect their eyes – 45% in France and 47% in the United States. The second most widespread preventive measure worldwide is visiting a vision care specialist. From this perspective, 30% of respondents believe there is nothing better than regular eye checks. It should be noted that people living in Western countries are much more likely to regularly visit a vision specialist: 48% in France, 41% in the United States and 31% in Germany. In Asia, regular checkups are much less common (11% in China and 7% in Japan).

The ubiquitous presence of screens is encouraging the most exposed individuals to protect their eyes

Respondents reported other prac­tices as well, but they are much less widespread and their intensity varies greatly from one country to another. It should be noted, however, that the ubiquitous presence of screens is en­couraging the most exposed individuals to protect their eyes. This reflects the fact that com­puters and tablets are now an integral part of the workplace for a large num­ber of people, with the proportion of those using lenses for protection from touch screens numbering on av­erage one in ten individuals among the surveyed population.

Lastly, certain measures are specific to certain cultures. For example, in Asia (mainly India and China), a sig­nificant percentage of the population reports regularly eating certain foods that supposedly have a positive effect on eyesight (47% in India and 41% in China). This type of prevention measure is much less common in Western countries, where food is more likely to be associated with health benefits unrelated to vision health.

Seniors and women are most concerned about protecting their eyesight

The survey confirms that certain segments are more concerned about protecting their eyes than the rest of the population. Not surprisingly, the older you get, the more likely you are to take steps to preserve your eyesight (see Fig. 2). Seventy-three percent (73%) of people over 50 report taking preventive measures compared to 66% of those under 35. Visiting an eye care professional is the factor that most differentiates the older popula­tion. While all generations have adopted the habit of wearing sun­glasses, the practice of regularly visiting a vision specialist increases with age. Forty-one percent (41%) of people over 50 report doing so com­pared to only 25% of those under 35. 

Seniors and women are most concerned about protecting their eyes

Another segment being proactive about caring for their eyes is women. For one thing, more women do some­thing to protect their eyesight: 70% versus 65% of men (see Fig. 3). Secondly, they are significantly more proactive than men when it comes to most preventive measures. Far more women than men, for example, report wearing sunglasses when they are outside (37% vs. 28%). Women are also more likely to regularly see a vision specialist (33% vs. 27%). Similarly, they are more likely than men to report taking into account the ability of certain foods to protect their eyesight (26% vs. 22%). Last but not least, more women than men lubri­cate their eyes (17% vs. 12%).

In short, women are currently more aware than men and act accordingly. This is a tuned-in population, which means that women are also seeking information on long-term protection.

Eye care professionals: an intermediary role among healthcare providers

A more detailed breakdown of the figures concerning visits to eye care professionals shows that 37% of respondents reported seeing an ophthalmologist (optometrist in English-speaking countries) at least once a year and 29%, an optician. These figures are significant: on average, one-third of the  population has contact with a vision specialist at least once a year. Yet when these figures are compared with those involving other specialists, it becomes clear that visits to other professionals are far more common. (Fig 4) This especially holds true when it comes to general practitioners, whom 63% of respondents report seeing at least once a year. And respondents report visiting dentists far more often than they do ophthalmologists. Fifty-nine percent report visiting an ophthalmologist at least once a year. Overall, eye care professionals rank behind dentists and, for women, gynaecologists. On the other hand, they rank ahead of dermatologists, osteopaths, cardiologists and nutritionists. Vision specialists play an important albeit intermediary role. In all of the survey’s countries, patients are much less likely to visit an eye care professional than a general practitioner, which is to be expected, but also far less likely than a dentist even though vision is a precious asset, as demonstrated by numerous surveys. For example, a survey conducted by Ipsos in 2013 [2] among young people aged 15-30 showed that the eyes, after the teeth, were the part of the body con­sidered most important to take excellent care of as early as possible. This opinion was consistent across Europe, the United States and China.

Europe ranks number one for the frequency of visits to general practi­tioners, while the number of visits to eye care professionals is relatively uniform among the other regions cov­ered by the survey. Americans are most likely to get regular eye check­ups and to see an ophthalmologist than any other nationality. In emerg­ing countries, the urban and online population has greater access to vision professionals.

Lastly, while seniors are more likely than young people to visit specialists, a significant percentage of young people get regular checkups. This fact can undoubtedly be explained, in part, by the role played by parents and schools.

Women and seniors: populations more concerned about protecting their eyesight

Protecting eye health is a widespread practice worldwide

In conclusion, it seems that while populations in most of the countries surveyed are aware of measures to protect their eyesight, certain seg­ments are more committed. In particular, women and seniors are more likely to see vision specialists and on a more regular basis. As a re­sult, they are priority targets for any prevention campaign. These results should also encourage eye care professionals to also target less committed populations, i.e. young people and men. This is a public health issue that requires more tar­geted information.
