If you are over 50 and don’t have your eyes examined at least once a year, you ought to have your head examined.
Many changes to vision happen so slowly, you may not realize that you have a problem. Finding problems early may make the difference between vision change and vision loss.
Sight is an important part of staying safe and independent.
As we get older it is normal that our vision changes. Our eyes may find it harder to read small print, take longer to adjust from light to dark and be more sensitive to glare from sunlight or unshielded light bulbs. There’s a decline in depth perception that can make it hard to judge distances, and perceiving contrasts and colors becomes more difficult.
Here are some simple adjustments you can make to your lifestyle that may seem like common sense, but having a reminder doesn’t hurt.
Turn on the lights.
Seeing better can sometimes be as easy as changing a light bulb! Putting 100- or 150-watt bulbs in your lamps can reduce eye strain (but make sure your fixture is designed for that wattage!). Brighter lighting in stairways can help prevent falls.
Don’t smoke.
Studies show that tobacco smoking is the biggest risk factor in the early onset of an eye disease called Age-related Macular Degeneration (AMD). This disease causes serious and permanent loss of central vision.
Reduce glare.
Lampshades, glare shields on TV screens and computer monitors and wearing sunglasses are simple ways to compensate for increased sensitivity. Wear sunglasses that provide 99 to 100% UV-A and UV-B protection when you go outside during the day. They will protect you from UV rays that can harm your eyes even on a cloudy day.
Protect yourself.
Many people suffer vision loss because of accidents in the home. Some ways to prevent damage to your eyes are:
- put a grease shield over frying foods
- make sure that spray cans and bottle nozzles are pointed away from you
- wear safety glasses in the workshop and when opening and using chemical products like ammonia
Eat your vegetables.
Studies show that a daily dose of the vitamins and minerals found in melons, citrus, carrots, spinach and kale may help slow the progress of age-related eye diseases such as macular degeneration, glaucoma or cataracts. Ask your doctor if he agrees with making these changes to your daily diet.
Stay active.
Some studies report that glaucoma patients who exercise at least three times a week can reduce their eye pressure by as much as 20%. Since some bouncing exercises can be harmful to glaucoma patients, ask your doctor for safe suggestions.
Here are the most common vision changes that come with age:
Presbyopia is a loss of clear vision of close objects or small print. Reading glasses usually solve the problem.
Cataracts are cloudy areas that keep light from passing through the lens to the retina at the back of the eye. If the central part of the lens is cloudy, you may not be able to read or drive unless the cataract is removed. 95% of cataract surgeries are successful.
Floaters are tiny spots or specks that float across the field of vision, that are often normal. If a floater appears right in your line of vision, move your eye around, and it will probably go away. If you notice a sudden change in the number or types of spots you see, or if they come with light flashes, see your eye doctor as soon as you can. These may be signs of a serious problem.
Dry eyes can become a problem if your tear glands are not making enough tears. Your eyes may feel gritty, itchy or burning. Your doctor may suggest using a humidifier in your home, or special eye drops that act as tears. In a few serious cases, surgery may be needed to correct the problem.
Tearing can become a problem when your tear glands make too many tears. It may be because you are very sensitive to light, wind or changes in temperature. Simply protecting your eyes by shielding them or wearing sunglasses may solve the problem. Or it may be a result of an eye infection or blocked tear duct, which can be treated. See your doctor to find the exact cause and treatment.
Vision loss
While finding and treating serious eye problems early may stop or slow it down, most vision loss is permanent. Early treatment can give you time to learn ways to remain active with low or no vision. You can discover ways to adapt to vision loss by contacting a local eye care center or the Canadian National Institute for the Blind.
Here are the most common reasons for age-related vision loss:
Glaucoma is an eye problem that develops when there is too much fluid pressure inside the eye. If not treated early, it can cause vision loss and blindness. Because most people have no early symptoms, it is very important to have regular eye exams. Treatment may include eye drops, medicine and/or surgery.
Age-related macular degeneration is an eye disease that occurs when the macula at the back of the eye is damaged due to aging or conditions such as diabetes. This disease results in permanent loss of central vision. Regular eye exams can detect the disease early on and laser treatments can slow down central vision loss.
Diabetic retinopathy is an eye problem linked to diabetes. It happens when the retina does not get enough oxygen. Symptoms include cloudy vision and seeing spots. This condition goes through many stages and can result in blindness. If you have diabetes, see your eye doctor regularly to check for changes in your vision. Treatment can slow down vision loss. Laser treatment in the early stages often proves successful.
In conclusion
So, forgive me if I am being repetitive. Sight is an important part of staying safe and independent. Finding problems early may make the difference between vision change and vision loss.
Do what you can to keep your eyes healthy. <<<
