As we age, the risk of developing certain eye conditions, such as age-related macular degeneration (AMD), increases. This condition is a leading cause of vision loss, and risk factors include lifestyle choices and diet. Genetics can also play a significant role in the development of AMD and how it progresses in an individual. Continue reading to learn how genetics affects your risk of developing AMD.

Vision is one of the most important senses that help us process, observe, and interact with the world around us. For many individuals, low vision has impacted their lives in a number of ways. Low vision can result from injuries to the eye, as well as conditions such as diabetic retinopathy. Whatever the cause, declining vision can impede the ability of an individual to perform everyday tasks, such as writing, reading, walking, and socializing. It is important to schedule regular eye exams to monitor the health of your eyes. Here, Dr. Stein discusses how quality of life is impacted by low vision.

The average worker spends seven hours a day on the computer for work purposes. In many cases, one or more of these hours is spent on a smartphone or tablet. Screens are so engrained in our society that there is an umbrella term for eye issues caused by excessive exposure.
Computer vision syndrome involves two main concerns for people who spend most of their days in front of a screen: dry eyes and eyestrain. Dr. Raymond Stein and our eye doctors at Bochner Eye Institute explain what causes these screen issues and how to prevent them.
Whether you work with images or text, your eyes are overwhelmed by the stimulating screen in front of you, and you forget to blink. The average blinking rate goes from 15 times per minute to just five to seven during computer usage. Your eye’s surface depends on a thin layer of liquid to protect it that is replenished by blinking. A lower blinking rate leads to dry eyes.
There could be a few culprits behind digital eye strain — one being the glare or brightness emanating from the screen, and the other that your prescription is out of date. People who don’t use reading glasses when they need them or need a new contact lens or glasses prescription have a harder time focusing on the text or images on a screen. Research suggests this is because the screen uses pixels with blurry edges unlike a piece of paper or book with defined print.
Computer vision syndrome symptoms may involve headaches, eyestrain, blurred vision, dry eyes and neck and shoulder pain. These concerns are often caused by a combination of issues associated with long-term computer use, such as poor lighting, inadequate viewing distance and uncorrected vision. Luckily, the symptoms are temporary, and there are several ways to alleviate and prevent computer vision syndrome including:

Preserving the health of your eyes is not just simple — it’s essential to the clarity of your sight and ultimately your enjoyment of life. By adopting a small number of key lifestyle choices and habits, you can help protect your eyes and ensure a lifetime of clear, vivid and panoramic vision.
Here, experienced Toronto ophthalmologist Dr. Raymond Stein of Bochner Eye Institute outlines the best strategies for supporting optimal eye health.
Sunglasses are an important way to protect your eyes, and not just on sunny days: Harmful ultraviolet rays easily pass through clouds and reflect off water and light-colored surfaces. Quality sunglasses with high levels of UVA and UVB protection are essential to preventing damage to your eyes and the development of conditions such as cataracts and macular degeneration.
Damaging ultraviolet rays are at the far blue end of the electromagnetic spectrum, but you can get an unhealthy dose of blue light even when you’re out of the sun. Computer screens and other digital devices emit blue light, as do high-definition TVs and the LED lights that are steadily replacing the old incandescent bulbs. Using a screen filter, special glasses designed for computer use, and simply limiting your screen time, are all smart ways to protect your eyes and reduce strain.
If you wear contact lenses, keeping them free of bacteria should be a priority. When bacteria develop on lenses or in lens containers that haven’t been properly cleaned or replaced, the results can range from irritation to serious infection. And some types of eye infection can lead to loss of vision.
Because the eye is so fragile, even a moderate amount of rubbing can result in damage. When rubbing causes small blood vessels to break, the eyes appear bloodshot. Leakage from capillaries can even create dark circles under the eyes.
In the process of rubbing the eyes, your hand may transfer germs to the area, which can cause conjunctivitis or other infections. If there is dirt, debris or a grain of sand in the eye, it can scratch the cornea when you rub your eyes. The effect is even greater if you wear contact lenses.
Too much rubbing can affect your vision, changing your prescription by shortening or lengthening the distance between lens and retina. It can also cause an increase in intraocular eye pressure, which is especially dangerous for those already suffering from elevated eye pressure.
