An eye disorder that slowly destroys sharp, central vision. This makes it difficult to see fine details and to read. It is caused by damage to the area around blood vessels that supply the macula. This change in the blood vessels damages the macula. The condition is rare before age 55, and is most often seen in adults 75 years or older, which is why it is often called age-related macular degeneration
Blurred vision. Often objects in the central vision look distorted and dim, and colours look faded. You may have trouble reading print but you can generally see well enough to walk and perform most routine activities.
As the disease becomes worse, you may need more light to read or perform everyday tasks. Straight lines appear distorted and wavy. A blurred or dark spot in the centre of vision gradually gets larger and darker.
