If poor eyesight is a factor, the size of the digital camera's LCD screen is crucial. Look for something with a screen larger than 2.5 inches, advises Elder Gadget. The larger the screen, the easier it will be to read text, judge shots before they're taken, and review pictures already shot.

For those with little technical knowledge, consider how easy it is to transfer the pictures off of the camera and have them printed. The camera should also have clearly marked controls and raised buttons. The instruction manual should be easy to follow.

Look for a camera that requires little manual work to take a good picture, such as auto focus, automatic light adjustment and image stabilization. Such features help compensate for poor vision and shaky hands.

Seniors dealing with a loss of dexterity will appreciate a camera designed for durability, with a good grip and a wrist strap to prevent dropping the camera.
