Between the ages of 40 and 50, the lens of the eye begins to gradually lose elasticity. This makes it harder to focus for close-up activities such as reading. As you get older, the lens of the eye also becomes thicker and yellower. These changes may affect the way you see colors and contrast. For instance, the color blue may appear darker and harder to tell apart from black or green. As the eye ages, the pupil gets smaller. This means that you need more light to see well, along with more time to adjust to changing levels of light (going from daylight into a dimly lit room, for example).
You may have low vision even though you do not have medical problems such as cataracts or glaucoma. However, if you notice any change in your vision, you should have an eye exam as soon as possible.
It may be harder to tell lighter colors from darker colors. You may have a hard time recognizing even the people who are most familiar to you. If you cannot see someone’s lips, it may be harder for you to communicate if you are also hard of hearing and so rely on reading lips.
Get regular eye exams so you can get help for any vision problems you have. There are aids and tools you can get that will help you read, write, and manage daily living tasks. You can try magnifying aids, audio tapes, electronic reading machines, and computers that use large print and speech.
Less than perfect vision does not have to hamper your lifestyle. Here are some simple changes that may help:
