Dockyard : Keep a check on eyes

As one age, he needs more light to see. Brighter lights in the work area or next to the reading chair will help make reading and other close-up tasks easier

Beginning in the early to mid-40s, many adults may start to have problems seeing clearly at close distances, especially when reading and working on the computer. This is among the most common problems adults develop between ages 41 to 60. This normal change in the eye’s focusing ability, called presbyopia, will continue to progress over time.

Initially, you may need to hold reading materials farther away to see them clearly. Or you may need to remove your glasses to see better up close. Print in the newspaper or on a restaurant menu may appear blurred, especially under dim lighting.

If you already wear prescription glasses or contact lenses to see clearly in the distance, these changes in your near vision can be corrected by switching to bifocal or multifocal lenses. Fortunately, people with presbyopia now have many options to improve their vision.

During these years, schedule a comprehensive eye examination with your optometrist at least every two years to check for developing eye and vision problems. Don’t rely on the limited driver’s license vision test or other insufficient vision screenings to determine if you have an eye or vision problem.

Adults over 40 who have the following health or work issues may be particularly at risk for developing eye and vision problems:

• Chronic, systemic conditions such as diabetes or high blood pressure.
• A family history of glaucoma or macular degeneration.
• A highly visually demanding job or work in an eye-hazardous occupation.
• Health conditions related to high cholesterol, thyroid, anxiety or depression, and arthritis for which you take medications. Many medications, even antihistamines, have vision side effects.

Just like your body, your eyes and vision change over time. While not everyone will experience the same symptoms, the following are common age-related vision changes:

• Need for more light. As you age, you need more light to see as well as you used to. Brighter lights in your work area or next to your reading chair will help make reading and other close-up tasks easier.
• Difficulty reading and doing close work. Printed materials can become less clear, in part because the lens in your eye becomes less flexible over time. This makes it harder for your eyes to focus on near objects than when you were younger.
• Problems with glare. When driving, you may notice additional glare from headlights at night or sun reflecting off windshields or pavement during the day. Changes in your lenses in your eyes cause light entering the eye to be scattered rather than focused precisely on the retina. This creates more glare.
• Changes in colour perception. The normally clear lens located inside your eye may start to discolour. This makes it harder to see and distinguish between certain colour shades.
• Reduced tear production. With age, the tear glands in your eyes will produce fewer tears. This is particularly true for women experiencing hormone changes. As a result, your eyes may feel dry and irritated. Having an adequate amount of tears is essential for keeping your eyes healthy and for maintaining clear sight.
