Lakeland Eye Clinic – Prevent damage from Blue Light?

Ciambrone Vision Real Tips from Your Lakeland, Florida Eye Doctor

Summary: Everywhere you look, there’s an article or blog telling you all about hazardous blue light. However, after years of experience as an optometrist in Lakeland, I’d like to point out that blue light isn’t the root of all evil. Your computer, phone, tablet, and every digital screen you own pose additional dangers to your vision and your sleep – beyond the dangers of blue light.

Is Blue Light the Big and Bad Enemy?

Blue light is a short, high-energy wavelength emitted in large amounts by all electronic devices. It can pass through the eye to the retina, and laboratory studies have shown how prolonged exposure to blue light damages the retinal cells in mice. That’s one fundamental reason behind the plentiful warnings to avoid blue light. However, the results of studies on real people (not rodents) didn’t attribute blue light with the same level of risk; other risk factors can be just as threatening to human vision.

Many eye diseases can be quickly and easily diagnosed during a Comprehensive eye exam, Pediatric eye exam and Contact lens 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? Is LASIK eye and vision surgery an option for you ? Our Lakeland eye doctor is always ready to answer your questions about eye disease and Contact lenses.

Eyes Block Blue Light Naturally

Although it’s true that digital tech emits a huge quantity of blue light, you may not know that the sun also shines mainly with blue light. In fact, on a sunny day, the light coming at you is nearly 100,000 brighter than your computer screen. Yet, few scientific studies on humans have uncovered any connection between sunlight exposure and the development of a retinal disease, such as age-related macular degeneration.

Then how did the studies show that blue light damages mice eyes? Because mice and people don’t have the same eyes. Humans have built-in protective elements – macular pigments and the natural filter of our crystalline lens – that protect against blue light. These parts of your eyes absorb the blue light before it reaches the retina at the back of your eye.

Of course, that doesn’t mean sunglasses are unnecessary. By blocking all UVA and UVB rays from your eyes, sunglasses provide many more benefits than just blocking blue light. For example, research has shown that sunglasses slow down the development of other eye diseases, such as cataracts.

Digital Devices Are Still Dangerous

Even though blue light may not be the ultimate threat posed by electronic gadgets, that doesn’t mean blue light has zero negative effects on your eyes or that your digital screens are harmless. Blue light has a powerful, adverse effect on your sleep physiology. That’s because you have photosensitive retinal ganglion cells that convey the time of day to your brain, based on how light it is in the environment. These ganglion cells, which are hypersensitive to blue light, help to set your internal clock to keep you awake and alert during the day. Therefore, when you stare at a digital screen and its blue light, your ganglion cells tell your brain it’s still daylight – even at 2 am.

What if you put a blue-light blocking filter on your tablet whenever you use it in bed? Sorry, no dice. Your retinal cells are also sensitive to light waves other than blue, so filtering out blue light won’t improve your sleep. Really, you need to dim all the colors, all the different wavelengths of light.

How to Relieve Tired Eyes and Promote Sleep

When my Lakeland eye clinic patients complain that their eyes are tired and they can’t sleep after looking at a screen from dawn through bedtime, I advise them to dim all screens starting from the evening hours. Bright light before bed (even from your phone screen) makes it harder to fall asleep. Even better, accept the challenge of making your bedroom a screen-free zone.

If you suffer from eye strain, it’s a good idea to call your Lakeland eye doctor and schedule an eye exam. It’s possible that you need a new vision prescription for glasses or contact lenses.

Last, but not least, keep your eyes lubricated! One of the best ways to do that is to blink frequently enough. When you stare at a screen, you’re probably blinking at a slower rate than normal. Consequently, your tear film evaporates and doesn’t get replenished until you walk away from your computer and begin to blink regularly again. In addition to blinking, using preservative-free artificial tears eye drops before you sit down at the computer can help boost your natural tears and keep your eye surface better lubricated.

Lakeland Contact Lenses- Overuse of Contact Lenses – What Happens? How Can You Prevent It?

Ciambrone Vision Tips from our eye clinic on how to keep your eyes healthy with contact lenses

Contact lenses can be a fantastic way to see crisp and clear without bothersome eyeglasses. They give a wider field of view and healthy, comfortable vision – as long as you don’t overuse them!

Nowadays, with so many quality contact lenses on the market that provide exceptional visual clarity and convenience, it’s easy to abuse their use. However, this practice poses serious risks to your eyes. To avoid damaging your vision, our eye clinic shares the following information about avoiding the overuse of contact lenses.

Many eye diseases can be quickly and easily diagnosed during a Comprehensive eye exam, Pediatric eye exam and Contact lens 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? Is LASIK eye and vision surgery an option for you ? Our Lakeland eye doctor is always ready to answer your questions about eye disease and Contact lenses.

How much use is overuse?

You should be removing your contact lenses for a minimum of 18 awake hours per week, giving your eyes time to rest and get sufficient oxygen. Your eyes need to absorb oxygen from the air (not from your lungs, like other organs), so allowing your eyes time to breathe without contact lenses in the way is essential.

Don’t leave home without eyeglasses

If you insert your contacts in the morning and will be out into the wee hours of the night, pack along a pair of glasses to switch to later in the day. This will help prevent eye strain and, ocular irritation.

Don’t sleep in contact lenses

Keeping your contacts in while dozing will damage your eyes, depriving them of oxygen and hydration. Without enough moisture, your contact lenses can dry out and lead to problems, such as corneal scratches.

Replace your contact lenses on time

Because modern contact lenses are made from advanced materials, they offer supreme comfort. That’s why so many people end up wearing them longer than prescribed – until they become uncomfortable. However, this is a risky practice that can lead to vision damage. When used for too long, contacts can develop tiny tears and accumulate calcium or protein deposits that can seriously irritate or injure your eyes. When you buy contacts from our eye clinic, we’ll provide you with instructions on how long each pair lasts and when to replace them.

What happens from the overuse of contacts?

There are three main problems that can result:

  • Giant Papillary Conjunctivitis (GPC): wearing your contact lenses for too long without changing them can lead to deposits in the lenses that cause Papillae (large granules that rub against the cornea) to form under the eyelids. As a result, you can experience itching, red eyes, light sensitivity, and the constant feeling that something is stuck in your eye.
  • Corneal ulcer: this is a serious infection that occurs on the outer layer of the eye and can damage vision. Wearing contact lenses while swimming can allow dangerous microbes to enter your eye. When these microbes stick to contacts, it increases your risk of corneal ulcers. Symptoms include redness, blurred vision, eye pain, and watering. Corneal ulcers require prompt medical treatment to prevent irreversible vision loss.
  • CLARE – Contact Lens Associated Red Eye: this sudden redness in your eye is typically caused by wearing contact lenses during bedtime. Insufficient oxygen to your cornea (because of tight-fitting contacts) is the culprit. It is a relatively mild problem, but you’ll need an eye exam at our eye clinic to determine whether you’re suffering from CLARE or an infection.

When you visit our eye clinic for a contact lens eye exam or fitting, we’ll be happy to provide you with instructions on the proper way to use your contacts – and not overuse them!
