What Are The Top Benefits To Wearing Computer Glasses?

What Are Computer Glasses and Do They Make a Difference?

Many people spend most of their waking hours staring at screens, exposing them to the potentially harmful effects of blue light. In fact, if you’re reading this on one of your screens, you’re exposing your eyes to blue light at this very moment.

All this screen time comes at a price: It can cause headaches, eyestrain, insomnia, and possibly eye disease. Blue light glasses (also known as computer glasses) have been touted to combat these problems head-on. But do they really make a difference to those who spend many hours a day staring at screens?

What Is Blue Light?

Blue light is a color in the light spectrum visible to human eyes — though it doesn’t actually appear blue to the naked eye.

It’s a short wavelength that produces high amounts of energy (from 400 to 500 nanometers) and is often referred to as high-energy visible light (HEV). In fact, any source of visible light emits blue light, whether it’s an artificial source like a digital screen or a light bulb, or a natural one, like the sun.

How Does Blue Light Affect Your Eyes?

It Obstructs the Wake/Sleep Cycle

Prior to the invention of artificial light, the sun regulated our sleep schedules. After sundown, the darkness signals to our bodies that it’s time to produce melatonin, the hormone responsible for enabling us to sleep.

Nowadays, we’re exposed to blue light throughout the day and late into the night. While exposure to any light in the evening hours delays the production of melatonin, blue light waves can be particularly problematic as they radically disrupt these signals, causing less melatonin to be generated.

This essentially throws off our natural body clocks, since the brain associates blue light with daytime, making it harder to fall asleep at night and wake up in the morning.

It May Increase the Risk of Macular Degeneration

A 2018 study by the University of Alcalá suggests that a high level of blue light exposure may increase one’s risk of macular degeneration later in life, which can lead to permanent vision loss.

This is because blue light penetrates right through the cornea to the retina, damaging light-sensitive cells in the retina.

It Can Potentially Cause Eye Strain

Blue light scatters more easily than other visible light. This unfocused light reduces contrast and can contribute to digital eye strain, characterized by headaches, neck pain, and blurred vision.

That’s where computer glasses come in.

Research has indicated that lenses that filter out blue light significantly increase contrast. Computer glasses with yellow-tinted lenses may improve comfort levels when viewing digital devices for prolonged periods of time.

Are There Benefits to Wearing Computer Glasses?

As mentioned above, computer glasses reduce blue light exposure from computer screens and other digital devices. But are they worth getting?

According to the American Macular Degeneration Foundation, blue light can cause retinal damage “at greater intensities,” but the amount of light emitted by screens is quite low. Whether there is a cumulative effect requires further research.

Getting Computer Glasses

If you decide to get blue-light blocking lenses, you can find stylish options with or without a prescription. So if you’re farsighted and wear progressive lenses or bifocals, you can get single-lens computer glasses to match your prescription.

You may want to consider getting photochromic lenses, as they provide protection from both UV and blue light, whether indoors or out in the sun. These lenses seamlessly and automatically darken when exposed to UV rays outdoors, and become clear again when indoors.

Do I have Eye Allergies?

Know the symptoms of seasonal eye allergies and how to get rid of this pesky problem

As the weather warms, flower buds are opening, and your neighbors are dragging their lawnmowers out for an annual spring tune-up. And suddenly you find a need to rub your itchy, red, and sore eyes constantly. Yep, it’s that time of year again – the time that seasonal allergies blossom with the trees.

Nasal symptoms of seasonal allergies, like a runny nose and sneezing, usually get all the attention, but actually, eye allergies (your eye doctor may call it “allergic conjunctivitis”) are pretty common – affecting millions of people in the US. Grass allergy and pollen in the eyes are the primary cause of eye irritation. What’s the best treatment? And how can you get rid of your eye allergies?

Eye exam to diagnose eye allergies in Lake Country, British Columbia eye doctor’s tips on how to recognize and relieve allergies.

The ocular symptoms of your seasonal allergies are caused when your body’s immune system becomes sensitized and overreacts to an environmental trigger that’s really harmless. That trigger, called an allergen, makes contact with antibodies in your eyes – and these cells respond by releasing histamine. Histamine and other natural chemicals cause tiny blood vessels in your eyes to leak, which can lead to redness, itchiness, burning, inflammation, and watery eyes. The symptoms can range from mild to severe enough to interfere with your clear vision. Rest assured – eye allergies are not dangerous, as annoying as they can be.

However, these symptoms alone are not enough to blame seasonal allergies. All of these signs are not unique to eye allergies and could point to several different eye diseases. That’s why a precise diagnosis is imperative! Our Lake Country, British Columbia eye doctor will perform a comprehensive evaluation of your eyes to identify the cause of the irritation.

Many eye diseases can be quickly and easily diagnosed during a comprehensive eye exam. If you were diagnosed with an eye disease, such as Cataracts, Glaucoma, Macular degeneration, Diabetic retinopathy, or Dry eye, you may be overwhelmed by the diagnosis and confused about what happens next. Will you need medications or surgery – now or in the future? Our Lake Country eye doctor has prepared the following answers to your questions about eye disease.

Avoid your trigger to get rid of eye allergies

Grass allergy and pollen in your eyes are the most typical triggers for seasonal eye allergies, often called hay fever. Since that’s the case, you’re probably wondering how you can possibly avoid these widespread allergens. Before you lock yourself in your room and wait for the seasons to change, our eye doctor recommends:

  • Keep windows closed when the pollen count is high. Use a/c in your home, office, and the car in order to clean the air around you.
  • Do not rub your eyes! This spreads the pollen (and irritation!) all over.
  • When you are outdoors, always wear glasses and sunglasses to keep pollen out of your eyes. Don’t wear your contacts! Contact lenses can exacerbate eye allergies because they are a great surface for pollen to cling to and pile up.
  • When you return indoors after being exposed to seasonal allergens, rinse your eyes with saline drops.
  • Clean your floors with a damp rag, instead of sweeping with a dry broom that pushes any pollen that’s settled back into the air.

What’s the best treatment for eye allergies?

Some of the symptoms can be managed with nonprescription drugs, especially if your eye allergies are mild. Try using artificial tears to keep your ocular surface clean. Decongestant eye drops may also help, however, it’s not a good idea to use these for more than a few days since they can worsen your condition with prolonged use.

What about antihistamines for red eyes and seasonal allergies? Antihistamine eye drops, mast cell stabilizer eye drops, corticosteroid eye drops, and NSAID eye drops are accepted short-term treatment for eye allergies. Because these are all prescription drugs, you will need to visit your eye doctor (and possibly an allergist too) to determine which medication is most suitable for you. Some non-sedating oral histamines may also be effective at relieving your symptoms, but they can dry out eyes – thereby making the irritation worse. If your seasonal allergies are extreme and get in the way of functional living, immunotherapy allergy shots or tablets may offer long-term relief.
