"Ageing well is about quality of life. Research holds the
key to unlocking the possibilities of ageing well" |
Changes in vision commonly occur with age. Some form
of visual handicap is found in more than 70% of people over 70. Some common
changes are:
- Reduced
field of view - due to eye recession in the eye socket, lowering
of the upper lid and some loss of peripheral receptors in the
retina
- Dry eyes
- due to diminished tear production
- Floaters
- due to chemical changes behind the lens
- Difficulty
adjusting to dim light - due to smaller pupil size and deficiencies
in the capacity of the retina to adapt to darkness
- Trouble
reading things closer than at arms length - due to changes in
lens elasticity and intraocular muscle tone
- Difficulty
with blue-green discrimination - due to yellow pigments accumulating
in the fluid behind the cornea
- Difficulty
taking in and assessing rapid changes in visual information
- due to slowing in brain processing
- Dazzle
with bright lights - due to small lens opacities and slowing
of pupillary responses
Minor adjustments to the home, such as choosing
good (but not bright) lighting, will assist in minimising the impact of
these changes.
If vision changes are causing you concern, please
consult your doctor.
