As one gets older (from about 40 years of age), one might observe some significant changes in vision and notice that the vision is not as it used to be. It is very normal to experience visual changes over time, so you shouldn’t be scared at all. However, you will need to schedule more routine visits to your eye doctor for proper diagnosis and treatment. This is because some age-related vision changes can permanently affect your eyesight. Listed below are visual conditions that come with ageing.


When proteins from the eye’s lens accumulate on the lens surface, the lens loses its natural transparency and becomes opaque, and this results in cloudy or blurry vision.

Cataracts usually develop in people that are 40 years and upward and can cause difficulty distinguishing between shades of colour. If left untreated, it can eventually lead to total vision loss.

Posterior vitreous detachment (PVD)

This condition happens when the gel-like substance behind the eye shrinks and detaches from the retina. Although this comes with the ageing process, it can cause eye floaters and sudden flashes of light in your visual field.

Presbyopia (Age-related farsightedness)

As we get older, the eye lens loses its ability to bring objects into close focus and this results in blurry vision. This condition affects adults from age 40. Using medically prescribed reading glasses or multifocal lenses will help with various daily tasks, like reading, knitting, texting and computer use.

Reduced pupil size

The older you get, the weaker the muscles controlling the size of the pupil and its reaction to light becomes. This results in a reduced rate at which the pupil responds to changes in the ambience of light. The pupils can also appear smaller than normal. When this happens, the affected person will see halos around sources of light, and also have difficulty reading, as well as making use of a computer in an environment with minimal lighting.


Regardless of your age, if you observe any unusual changes in your vision, it is expedient that you schedule an appointment with your doctor for an eye exam. He/she is in the best position to discuss the changes and assist you with the information needed to keep your vision healthy.
