You may think your eyes are healthy, but visiting an optometrist for a comprehensive dilated eye exam is the only way to really be sure. During the exam, each eye is closely inspected for signs of common vision problems and eye diseases, many of which have no early warning signs. Annual comprehensive dilated eye exams are generally recommended starting at age 60. However, African Americans are advised to start having comprehensive dilated eye exams starting at age 40 because of their higher risk of glaucoma. It’s also especially important for people with diabetes to have a comprehensive dilated exam at least once a year.

Dilation is an important part of a comprehensive eye exam because it enables your eye care professional to view the inside of the eye. Drops placed in each eye widen the pupil, which is the opening in the center of the iris (the colored part of the eye). Dilating the pupil allows more light to enter the eye the same way opening a door allows light into a dark room. Once dilated, each eye is examined using a special magnifying lens that provides a clear view of important tissues at the back of the eye, including the retina, the macula, and the optic nerve.

In a person with diabetic retinopathy, the most common diabetic eye disease and a leading cause of blindness in the Canada, the exam may show swelling or leaking of blood vessels in the retina, the light-sensitive layers of tissue at the back of the eye. The eye care professional may also see an abnormal growth of blood vessels in the retina associated with diabetic retinopathy.

In age-related macular degeneration (AMD), a common cause of vision loss and blindness in people over the age of 50, the exam may show yellow deposits called drusen or clumps of pigment beneath the retina. In some cases, the exam may also show abnormal growth of blood vessels beneath the retina. These AMD-related changes tend to cause deterioration of a small area of the retina called the macula, which is needed for sharp, central vision.

A comprehensive dilated eye exam is also critical for detecting glaucoma, a disease that damages the optic nerve, which carries information from the eyes to the brain. In a person with glaucoma, the dilated exam may show changes in the shape and color of the optic nerve fibers. The exam may also show excessive cupping of the optic disc, the place where the optic nerve fibers exit the eye and enter the brain.

Tonometry is a test that helps detect glaucoma. By directing a quick puff of air onto the eye, or gently applying a pressure-sensitive tip near or against the eye, your eye care professional can detect elevated eye pressure, which can be a risk factor for glaucoma. Numbing drops may be applied to your eye for this test.

A Visual field test measures your side (peripheral) vision. A loss of peripheral vision may be a sign of glaucoma.

A Visual acuity test will require you to read an eye chart, which allows your eye care professional to gauge how well you see at various distances.

Simple Eyecare Tips To Keep Your Eyes Healthy

Simple Tips for Healthy Eyes

Your eyes are an important part of your health. There are many things you can do to keep them healthy and make sure you are seeing your best. Follow these simple steps for maintaining healthy eyes well into your golden years.

Have a comprehensive dilated eye exam. You might think your vision is fine or that your eyes are healthy, but visiting your eye care professional for a comprehensive dilated eye exam is the only way to really be sure. When it comes to common vision problems, some people don’t realize they could see better with glasses or contact lenses. In addition, many common eye diseases such as glaucoma, diabetic eye disease, and age-related macular degeneration often have no warning signs. A dilated eye exam is the only way to detect these diseases in their early stages.

During a comprehensive dilated eye exam, your eye care professional places drop in your eyes to dilate or widen, the pupil to allow more light to enter the eye the same way an open door lets more light into a dark room. This enables your eye care professional to get a good look at the back of the eyes and examine them for any signs of damage or disease. Your eye care professional is the only one who can determine if your eyes are healthy and if you’re seeing your best.

Know your family’s eye health history. Talk to your family members about their eye health history. It’s important to know if anyone has been diagnosed with a disease or condition since many are hereditary. This will help to determine if you are at higher risk of developing an eye disease or condition.

Eat right to protect your sight. You’ve heard carrots are good for your eyes. But eating a diet rich in fruits and vegetables, particularly dark leafy greens such as spinach, kale, or collard greens is important for keeping your eyes healthy, too. I Research has also shown there are eye health benefits from eating fish high in omega-3 fatty acids, such as salmon, tuna, and halibut.

Maintain a healthy weight. Being overweight or obese increases your risk of developing diabetes and other systemic conditions, which can lead to vision loss, such as diabetic eye disease or glaucoma. If you are having trouble maintaining a healthy weight, talk to your doctor.

Wear protective eyewear. Wear protective eyewear when playing sports or doing activities around the home. Protective eyewear includes safety glasses and goggles, safety shields, and eye guards specially designed to provide the correct protection for a certain activity. Most protective eyewear lenses are made of polycarbonate, which is 10 times stronger than other plastics. Many eye care providers sell protective eyewear, as do some sporting goods stores.

Quit smoking or never start. Smoking is as bad for your eyes as it is for the rest of your body. Research has linked smoking to an increased risk of developing age-related macular degeneration, cataract, and optic nerve damage, all of which can lead to blindness.

Be cool and wear your shades. Sunglasses are a great fashion accessory, but their most important job is to protect your eyes from the sun’s ultraviolet rays. When purchasing sunglasses, look for ones that block out 99 to 100 percent of both UV-A and UV-B radiation.

Give your eyes a rest. If you spend a lot of time on the computer or focusing on any one thing, you sometimes forget to blink and your eyes can get fatigued. Try the 20-20-20 rule: Every 20 minutes, look away about 20 feet in front of you for 20 seconds. This can help reduce eyestrain.

Clean your hands and your contact lenses properly. To avoid the risk of infection, always wash your hands thoroughly before putting in or taking out your contact lenses. Make sure to disinfect contact lenses as instructed and replace them as appropriate.

Practice workplace eye safety. Employers are required to provide a safe work environment. When protective eyewear is required as a part of your job, make a habit of wearing the appropriate type at all times and encourage your coworkers to do the same.
