Speaker Ziwei Wu(吳紫薇）, PhD, Indian University Bloomington, Doctor of Optometry, New England College of Optometry introduced us Eye disease and eye care.
She started with eye structor, the most common part is 1. Sclera, 2. Lens, 3. Retina, and 5. Choroid. There are common eye disease which many seniors are suffering: 1.Presbyopia, 2. Cataract 3.macular degeneration 4. Dry Eyes, 5. Glaucoma
Presbyopia: This is when you lose the ability to clearly see close objects and small print. It's a normal process that happens slowly over a lifetime, although you may not notice any change until after age 40. Presbyopia is often improved or corrected with reading glasses, LASIK, and other procedures. She clarified the misconception of most people are holding, correction glasses are completely safe to wear, as long as patient go see with the professional OD to get their accurate prescription.
Dry Eyes:This happens when tear glands can't make enough tears or they make poor quality tears. Dry eyes can be uncomfortable, causing itching and burning. Rarely, they can lead to some loss of vision.
She suggested using a humidifier in your home or special eye drops that are similar to real tears. Systane eye drop is recommend for dry eye patients during day time, Gental Gel eye drop is the best before go to bed. She also suggested patients use hot pads, this method has been clinical proofed to be effective, each pad cover eyes for 2 mins, 10 mins in total, 2 times a day.
Cataract:Cataracts are cloudy areas that develop within the eye lens. A healthy lens is clear like a camera's, and light has no problem passing through it to the retina at the back where images are processed. When you have a cataract, the light can't get through as easily and, as a result, you can't see as well. Cataracts often form slowly, and they don't cause symptoms like pain, redness, or tearing in the eye. Some stay small and don't affect your eyesight. If they become large or thick, cataracts can usually be removed by surgery.
Macular Degeneration (AMD) AMD is a common eye condition and a leading cause of vision loss among people age 50 and older. It causes damage to the macula, a small spot near the center of the retina and the part of the eye needed for sharp, central vision, which lets us see objects that are straight ahead. Currently, no treatment exists for early AMD, which in many people shows no symptoms or loss of vision.
Glaucoma: This condition is often associated with a buildup of pressure in your eye. The eye is like a tire; some pressure is normal and safe. But when the pressure goes up, it can lead to damage of the optic nerve. This is called primary open angle glaucoma. Because most people with primary glaucoma have no early symptoms or pain, it's very important to have an eye doctor check your eyes regularly. Treatment may include prescription eye drops or surgery.
- Regular Eye Exams (age 45+ or record of family history)
- Blink exercise (blink regularly)

- If you need reading glasses to look at the screen or paper, wear them.
- Keep the proper distance of the screen or paper.
- Read under the bright lights
- Physical exercise
