    Learn about how the eye develops from infancy through to adulthood.

    It is normal for our eyes and vision to change during our lives. The first important changes occurring during infancy as our eyes and visual system continue to develop after we are born.  During our lives some of us may require glasses or contact lenses to correct our "distance" vision.

    For all of us, as we age, our eyes' ability to focus on near objects slowly decreases, which means that from about the age of 40, near vision correction devices (reading glasses) can be very useful. As we get older, age related changes such as cataract and macular degeneration can also affect our eyes and how well we can see. 


    A baby is born with the eye structures needed for vision, but must learn how to use them together to be able to "see". Focusing ability, the ability to use two eyes together, hand-eye coordination, colour vision and visual acuity (how well we can see) all continue to develop during infancy.


    The eyes continue to develop throughout childhood. Early eye tests are critical to check that children are developing normal, healthy vision. It can be at the start of education that the first signs of an eye problem are presented, the child may have difficulties reading or seeing the board at school. It is very important to detect any vision problems as soon as possible, because the younger a child is treated, the better the chance of responding to treatment. 


    Routine sight tests are important to continue to monitor vision standards, and to detect any further vision problems or conditions. This could also be a time when contact lenses are considered as teenagers may be more conscious about their appearance. 


    As we get older, our vision changes. It is normal that around the age of forty the lens inside our eyes begins to lose its ability to change shape and focus on near objects. Even if you have not worn glasses in the past, many people require near vision or reading glasses from about the age of 40.


    As we age, the risk of developing age related eye conditions such as cataract and AMD increases. It is important to continue to have regular eye checks to ensure that such conditions can be detected and managed appropriately.
