The cornea (the eye’s outermost layer, It is the clear, dome-shaped surface that covers the front of the eye) is unevenly curved.
There are two types:
Regular – The cornea (the eye’s outermost layer, It is the clear, dome-shaped surface that covers the front of the eye) is more curved in one direction than the other.
Irregular – The cornea (the eye’s outermost layer, It is the clear, dome-shaped surface that covers the front of the eye) is curved in multiple directions or the curve is steeper at the bottom.
This causes the light that enters the eye not reach the right point focal point at the back of the eye causing vision problems.
Waardenberg syndrome (a genetic condition that causes hearing impairment (see entry Deafness) from birth, colour changes in the iris of the eye, hair, and skin, and a characteristic facial appearance)
Complications /Information to beware of/General tips:
Eye Test and Driving Authority
One should have routine eye tests at least every two years but if one has concerns one should book an eye test at any point
Persons over 40 years should have eye test at least every 2 years and you must tell drivers authority if it affects your driving
Exercise your eyes
Focus change
This exercise works by challenging your focus. It should be done from a seated position.
Hold your pointer finger a few inches away from your eye.
Focus on your finger.
Slowly move your finger away from your face, holding your focus.
Look away for a moment, into the distance.
Focus on your outstretched finger and slowly bring it back toward your eye.
Look away and focus on something in the distance.
Repeat three times.
Near and far focus
This is another focus exercise.
As with the previous one, it should be done from a seated position.
Hold your thumb about 10 inches from your face and focus on it for 15 seconds.
Find an object roughly 10 to 20 feet away, and focus on it for 15 seconds.
Return your focus to your thumb.
Repeat five times.
Figure eight
This exercise should be done from a seated position as well.
Pick a point on the floor about 10 feet in front of you and focus on it.
Trace an imaginary figure eight with your eyes.
Keep tracing for 30 seconds, then switch directions.
20-20-20 rule
Eye strain is a real problem for a lot of people. Human eyes are not supposed to be glued to a single object for extended periods of time. If you work at a computer all day, the 20-20-20 rule may help prevent digital eye strain.
To implement this rule, every 20 minutes, look at something 20 feet away for 20 seconds.
Vision therapy
Vision therapy may include eye exercises, but only as part of a more specialised treatment program done under the supervision of an eye doctor, optometrist, or ophthalmologist.
The goal of vision therapy can be to strengthen the eye muscles.
It also can help to retrain poor visual behaviour, or help with eye tracking issues.
