Common Habits That Could Harm Your Eyes

Sunday, February 28th, 2021

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.

Ultraviolet Rays

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. 

Digital Screens

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.

Contact Lens Habits

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.

Rubbing Your Eyes

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.

Understanding the Different Types of Cataracts

Monday, February 15th, 2021

When cataracts develop, images progressively become duller and hazier. Colors fade and vision slowly dims. These effects have real consequences for the quality of life and safety of individuals whose cataracts have become advanced.

Although the effects are the same, the types of cataracts that precipitate this visual decline vary. Here, experienced Toronto ophthalmologist Dr. Raymond Stein of Bochner Eye Institute reviews the fundamental causes and effects.

Classifying Cataracts

Cataracts occur when the lens becomes cloudy, obscuring the image it projects on the retina. This process can begin in our 60s, and becomes more common with each passing year.

The most common type of cataract follows this age-related pattern, and is referred to as a nuclear sclerotic cataract. With this variety of cataract, the central part of the lens (nucleus) hardens and gradually becomes yellow or brown. Cortical cataracts, by contrast, form around the edges of the lens nucleus. When the clouding begins at the back of the lens, the result is a posterior capsular cataract.

Congenital cataracts are less common, and are usually detected during a child’s first year. Medications or diseases such as glaucoma and diabetes can cause a type of cataracts referred to as secondary cataracts. Injury to the eye sometimes results in traumatic cataracts, which may appear years after the initial impact or injury. Radiation cataracts can develop in cancer patients who are receiving radiation treatment.

A Proven Solution

In each case, the solution is the same: cataract surgery, a simple, convenient and routine procedure. Millions of cataract surgeries are performed each year. In this procedure, the clouded lens is removed and replaced with a lens implant that will remain clear for life. Originally performed with the use of a miniature blade, cataract removal is now done using a femtosecond laser to make incisions.

As a premier eye surgeon, Dr. Stein performs advanced cataract surgical procedures for patients in Toronto and throughout Ontario. He also offers state-of-the-art intraocular lenses that will replace your natural lens with a permanent, resilient artificial version that, depending on your choice, can give you superb vision at a variety of distances.
