What is 6/6 VISION?
Herman Snellen, a Dutch ophthalmologist, published his Snellen Chart in 1862. To this day, the Snellen Chart is still used to quantify how well we can see.
What is eye dominance?
Even though you think you’re looking at something with both eyes equally, what’s actually happening is, your brain is taking more input from one eye than the other. Everyone has a dominant eye, which is better for aiming (just ask anyone who’s done shooting or archery and they’ll know all about it). The brain favours one eye in telling it how far away something is and where you are in relation to it. So, when you’re identifying your target in sport, this needs to be taken into account. Whilst our eyes are meant to work together as a team, one eye will dominate and more accurately provide information about the location of objects. Having binocular vision (two eyed vision), helps us with locating objects in space and judging distances. In spite of this, one eye will dominate.

One pair of glasses can never fullfill all of your visual functions
Eye care needs can more or less be divided into two age groups. Under forty and over forty or, pre-presbyopic and presbyopic. From the age of forty onwards, the focusing mechanism of our eyes starts to deteriorate and what this means, is that we require different strengths of lenses for distance vision and near vision. When we fixate close-up, the lenses in our eyes, at lighting speed, change shape and give us more focusing power to obtain clear vision at near. It is this focusing power that we begin to lose because the lenses start to lose their elasticity. This a normal aging process.
“Lazy Eye“Disorder – What is Amblyopia?
Amblyopia, also called lazy eye, is a disorder of sight due to the eye and brain not working well together because vision in one or both eyes does not develop properly during childhood. The cause of amblyopia can be any condition that interferes with focusing during the first few years of life. This can occur […]
The amazing focusing mechanism of the eye
What is accommodation (focusing) and why is it important? Our eyes accommodation (focusing) system enables us to see up close. This is important when reading, using smart devices, applying make-up, sewing and using the computer.
