lose flexibility. If you get tired of holding books at arm’s length, you can fix the problem with a pair of reading glasses.
2. Floaters.
Most often these spots that drift across your field of vision are no cause for alarm. Some people are born with floaters, but they can also result when the fluid in your eye deteriorates through age, injury, or disease. However, you should call an eye doctor if the floaters suddenly become more common, or are accompanied by flashes of light. These may be symptoms of a detached retina.

3. Dry eyes.
If your tear glands dry up, your eyes can burn and itch and you may even lose some vision. A humidifier in your house or special eye drops can help restore the moisture, although the most severe cases will require surgery.
4. Tearing.
Eyes that are highly sensitive to sunlight, wind, or temperature changes often fill up with tears. You can prevent the problem with sunglasses or anything else that shields your eyes from the elements. In some cases, tearing can signal an eye infection or a blocked tear duct. See an ophthalmologist if the problem persists.
Certain medications can also affect your vision and have side effects such as blurred vision, dry eyes, and light sensitivity. Most effects are temporary and will stop when you quit taking the medicine, but it’s important to keep your eye doctor up to date on all the drugs and supplements that you’re using.

What can you do if your vision is fading?
If your vision has declined slightly, simply adding more light to your house may bring life back to normal. For activities like reading and sewing, add lamps that are brighter than overall room lighting. Shades, blinds, and drapes can reduce indoor glare, and an anti-reflective coating on your eyeglass lenses can be helpful, too.
Even with more severe vision loss, you may be able to continue reading and performing other tasks with the aid of special telescopic glasses, magnifying glasses, and electronic reading devices. Talk to your eye doctor about the devices that are best for you.
