What is a cataract? How will I know when I have one? What can be done to fix it?

A cataract is a clouding of the crystalline lens. The crystalline lens sits behind the iris or the colored part of the eye. Its function is to fine-tune our focusing system by changing shape as we view objects at different distances. Our lens eventually loses its ability to change shape; this is when we require reading glasses or bifocals. In addition, the crystalline lens can become cloudy or yellow as a part of normal aging. This is also known as an age-related cataract. Normal, age-related cataracts are unavoidable and everyone will develop them at some point if they live long enough. The discoloration of the lens leads to an overall blur, a decrease in contrast sensitivity, and a worsening of glare, especially at nighttime. Because they tend to develop gradually, the symptoms are often unnoticed by the patient. A yearly eye exam will allow your optometrist the opportunity to identify cataracts and advise on how to proceed. When your optometrist decides your cataracts are affecting your vision and are advanced enough to remove, you will meet with an ophthalmologist. Cataract surgery is a safe and effective outpatient procedure that will reverse any vision loss caused by cataracts, and it is usually covered by your medical insurance.

My previous eye doctor told me I have “stigma!” Am I going to go blind?

Stigma is actually referring to a type of refractive error known properly as astigmatism, and no, you will not go blind from having astigmatism; it is not a disease, in fact, it is relatively common. There are three types of refractive error, myopia, hyperopia, and astigmatism. The former two are more regularly referred to as nearsighted (cannot see far away) and farsighted (cannot see up close). Astigmatism is simply the third category; it affects both the near and far vision at the same time. Much like nearsightedness or farsightedness, astigmatism is corrected using glasses or contacts. Technically speaking an eye with astigmatism requires two different prescriptions to correct vision in one eye due to the more oval shape of the cornea. This will require a more specialized contact lens and a more in-depth fitting procedure. Nonetheless, your eye care provider can, and will, correct your astigmatism with glasses and/or contacts.

What exactly is glaucoma?

Glaucoma is a condition in which the eye's intraocular pressure (IOP) is too high. This means that your eye has too much aqueous humor in it, either because it produced too much, or because it's not draining properly. Other symptoms are optic nerve damage and vision loss. Glaucoma is a silent disease that robs the patient of their peripheral vision. Early detection is very important.

My eyes are always burning and tired, what is causing this and what can I do about it?

These are often signs of dry eye syndrome, a very common condition that affects many people over time. Women are generally more prone to developing these symptoms and aging is often a cause as well. Dryness of our eyes is often due to a decrease in the oil production in our eyelid glands which causes the surface of the eye to become irritated. Certain medications and health issues can also contribute to dryness. There is no true cure for dryness but many treatments are available such as the use of artificial tears, nutritional supplements incorporating Omega 3, prescription medications such as Restasis, and eyelid hygiene. No single treatment works for every individual so we customize treatments for each person and their specific condition.

What Are the Best Ways to Take Care of Your Eyes?

Around the world, more than 30 million people suffer from blindness. Conditions such as cataracts, glaucoma, macular degeneration, diabetic eye disease and eye trauma make up the bulk of these cases. Unfortunately, as the COVID-19 pandemic continues, additional factors – such as excessive screen time – have led to a further decline in global eye health. It’s never been a better time to focus on the necessity of quality eye care!

The most significant action you can take to optimize your eye health is to visit an eye doctor near you for regular eye exams. When you consider the fact that about 80% of all vision impairment could have been prevented by early detection and treatment, it’s a glaring alert that too many people are unaware of the need to schedule regular visits to an eye clinic near you.

In addition to eye exams, follow these simple and effective tips for promoting good eye health:

Match your glasses to their function

If you spend a lot of time outdoors, be sure to wear sunglasses with 100% UV protection to protect your eyes from the dangerous effects of UV rays. Too much sun exposure has been associated with cataract formation and other serious eye diseases.

If you spend a lot of time on a computer or any digital device, you can help prevent computer vision syndrome by blocking hazardous blue light emitted from the screen. Ask an optometrist near you about computer glasses with a blue light filter.

Eat Right for Your Eyes

- Leafy green vegetables, such as broccoli, spinach and kale, are rich with lutein and zeaxanthin, both of which can help limit the development of AMD and cataracts. Lutein also boosts the pigments that prevent hazardous UV rays from damaging your eyes.
- Vitamins C and E and zinc have been linked to a lower risk of age-related macular degeneration.
- Antioxidants, found in abundance in yellow peppers, egg yolk, sweet potatoes, pumpkins, carrots and blueberries, can help protect your peepers against sun damage.

Moisturize Your Eyes

Dry eye syndrome is a common condition, and it is occurring more frequently worldwide as pollution worsens. Long periods spent in front of the computer have also contributed to the growing incidences of dry eye. If you suffer the irritating symptoms of this condition, visit an eye doctor near you for an evaluation and treatment. You can also help yourself by resting your eyes and blinking often enough, which lubricates the eye surface. If necessary, use preservative-free artificial tears eye drops to soothe dry, irritated eyes.

- - - What is diabetic eye disease?
      
      Diabetic eye disease is a condition which can occur at any stage or type of diabetes. In fact, many times diabetes is identified during an eye exam in a person who never suspected they may have diabetes. It is caused by damage to the very delicate blood vessels within the retina. Over time, these blood vessels may start to leak blood and fluid into the retina or other areas of the eye. If the condition progresses, new vessels may begin to grow within the retina, which places the retina at risk of additional and sometimes sudden complications including internal bleeds and retinal detachment.
    - My doctor says I have a cataract, but he wants to wait a while before removing it. Why?
      
      A cataract usually starts very small and practically unnoticeable but grows gradually larger and cloudier. Your doctor is probably waiting until the cataract interferes significantly with your vision and your lifestyle. You need to continue to visit your eye doctor regularly so the cataract’s progress is monitored. Some cataracts never really reach the stage where they should be removed. If your cataract is interfering with your vision to the point where it is unsafe to drive, or doing everyday tasks is difficult, then it’s time to discuss surgery with your doctor.

      Glaucoma is a condition in which the eye’s intraocular pressure (IOP) is too high. This means that your eye has too much aqueous humor in it, either because it produced too much, or because it’s not draining properly. Other symptoms are optic nerve damage and vision loss. Glaucoma is a silent disease that robs the patient of their peripheral vision. Early detection is very important.
    - Do eye vitamins help stop macular degeneration?
      
      While there is no definitive cure for macular generation, only treatments to halt or slow the progression, eye vitamins are shown in some studies to help strengthen the macula and aid in keeping this central area of the retina stable. Vitamins for this condition need to be rich in Lutein, Zeaxanthine, and Omega 3’s such as fish oil. Most vitamins for the eye can be found over the counter without a prescription.’

What Causes Halos Around Lights?

Have you ever seen bright rings or “halos” around sources of light? Read on to learn what can cause halos and when they’re a reason to visit an eye doctor near you.

For local Management of Ocular Diseases near you in Blackfoot, Idaho

Seeing bright rings or “halos” around sources of light can either be normal or a cause for concern. Below, we’ll explain the most common reasons that people see halos and when you should visit your eye doctor.

We see halos around light fixtures and headlights when light entering the eye from a bright object is bent in an unusual way. This causes the bright light to appear as if it is surrounded by a ring of light, known as a halo. Several conditions can cause light to bend in this way.

CataractsA cataract is a clouding of the eye’s natural lens. Cataracts usually develop slowly and are most often seen in older people.When the lens becomes cloudy, light is dispersed abnormally as it enters the eye and causes a person to see halos around lights. In fact, seeing halos around lights is one of the most common symptoms of cataracts. Other symptoms that may accompany cataracts are blurred vision, light sensitivity, and difficulty seeing at night.
AstigmatismThis eye condition occurs when the cornea (the front surface of the eye) is irregularly curved. People with astigmatism may see halos around lights because of the way the cornea refracts incoming light.
Fuch’s Dystrophy This progressive genetic disease causes the cornea to swell. As the cornea swells and becomes misshapen, it causes light to enter at an incorrect angle. As a result, people with this condition see halos around lights.
GlaucomaGlaucoma occurs when the optic nerve becomes damaged due to high inner eye pressure, and is a leading cause of blindness worldwide. Seeing halos around lights can be an early sign of acute glaucoma, which is considered a medical emergency.If you suddenly start seeing halos around lights in addition to other symptoms like headache, vomiting, blurred vision, eye pain, and weakness, seek medical care without delay.
Dry Eye SyndromeDry eye syndrome occurs when the eyes are chronically dry. In moderate to severe cases, the eye’s surface can become irregularly shaped, which can cause light to enter at an odd angle.

When To Visit Your Eye Doctor

If you see halos around lights, it’s best to schedule a timely eye exam at an eye clinic near you, even if you suspect you know why it’s happening.

A comprehensive eye exam by a qualified eye care professional is the only way to rule out a serious problem.

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, Pink Eye or conjunctivitis, Myopia or Nearsightedness , 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 Blackfoot eye doctor is always ready to answer your questions about eye disease and Contact lenses.
