There are several eye problems that become more common among people as they age, although they can affect anyone at any age. They include:

Presbyopia. This is the loss of the ability to clearly see close objects or small print. It is a normal process that happens slowly over a lifetime, but you may not notice any change until around age 40. Presbyopia is often corrected with reading glasses and contacts.
Floaters. These are tiny spots or specks that float across the field of vision. Most people notice them in well-lit rooms or outdoors on a bright day. Floaters often are normal, but they can sometimes indicate a more serious eye problem, such as retinal detachment, especially if they are accompanied by light flashes. If you notice a sudden change in the type or number of spots or flashes you see, visit your eye doctor as soon as possible.
Dry eyes. This happens when tear glands cannot make enough tears or produce poor quality tears. Dry eyes can be uncomfortable, causing itching, burning, redness, or rarely, some loss of vision. Your eye doctor may suggest using a humidifier in your home or special eye drops that simulate real tears. Tear duct plugs, prescription eye drops or surgery may be needed in more serious cases of dry eyes.
Tearing. Having too many tears can come from being sensitive to light, wind, or temperature changes. Protecting your eyes by shielding them or wearing sunglasses can sometimes solve the problem. Tearing may also mean that you have a more serious problem, such as an eye infection or a blocked tear duct. Your eye doctor can treat or correct both of these conditions.
