We visited Dr Hana Abou Zeid - Spéc. FMH Ophthalmology et Ophthalmological surgery to discuss a few misconceptions about eyes and vision…
Eating carrots will improve your vision. True or False ?
This is false… the vitamin A contained in carrots doesn’t improve vision but it does help to maintain the retina’s health and thus, maintains general eye health as well.
In fact, fish is also very beneficial for the eyes. Its high concentration in omega 3 allows the preservation of the eyes' surface and helps improve ocular dryness.
Wearing glasses will make your eyes “lazy”. True or False ?
This is false. On the contrary, wearing glasses can relieve certain tensions and helps avoid aggravation in cases of poor vision.
Computer screens and tablets are bad for the eyes and are causing an epidemic of myopia (nearsightedness). True or False ?
It is true that screens can strain the eyes and can aggravate the effects of ocular dryness. The increasing presence of myopia is rather due to near vision and thus indirectly linked to screens. In the case of children, it is true that excessive near vision can accelerate the development of myopia. To avoid this, it is important to favor outdoor activities as much as possible before the age of 20.
Moreover, the blue light originating from screens has proven to have harmful effects on the retina. Protective filters have been developed to decrease these effects and can be added on request to a pair of glasses or to a computer screen.
Light-colored eyes are more sensitive. True or False ?
This is true. Light-colored eyes have a thinner iris (the colored part of the eye) and give way to more light and UV radiations of sunlight. On the long-term, this accelerates ocular ageing on all parts of the eye. Interestingly, I would add that nature was “well planned” as you will notice that, generally speaking, people originating from southern, sunnier cultures will often have dark eyes, whereas light eyes are more frequent in Nordic countries.
Everyone will have presbyopia (long-sightedness) at some point in their life. True or False ?
This is true. The natural ageing of the eye lens makes it lose its elasticity with time and complicates the ability to see close up and from far away at the same time.
The cataract (blurred vision) is also inevitable with age. The same natural ageing of the eye lens causes it to cloud up and block the light. At this point, a benign frequent operation can be performed allowing to regain an excellent vision without complications in 90% of cases.
Moreover, a new technology of operation with Femto laser allows for very delicate gestures with excellent results and very little complications.
Our iris is absolutely unique. True or False ?
This is absolutely true. Each person's irises are completely unique and impossible to recreate. In certain films, we can witness iris recognition through scanning of the eyes. This can indeed be used just like finger prints are and it is even more trustworthy as it is impossible to imitate.
