The Different Health Benefits of Daily and Monthly Contacts

The Hargrave Eye Center’s latest post:

Contact lenses may have been around longer than many might think. Especially, when one discovers that the first contact lenses manufactured were in 1887. Those early lenses were made of glass, created to cover the entire eye, and, as one can imagine, were said to be terribly uncomfortable. This is a wide departure from the little plastic or silicon discs most people are familiar with. However, as contact lens technology has advanced the array options available grown.


There are three main types of contact lenses available, daily, weekly, and monthly. Daily disposable lenses are typically worn only for the day and then thrown away after you remove them. This type of lens is generally made of thinner material both to keep the costs lower and for easy disposal. The other two types of contact lenses are weekly and monthly disposable. Monthly disposable lenses were the standard for a long time and although that is not the case any longer, some people still opt for this version. Both of these options are made of sturdier material than the daily disposable lens type so that they may be used several times before they need to be replaced. Both of these options also require daily cleaning, storage and overnight soaking in solution.


There are a few factors that one needs to consider if they decide to wear contact lenses; the prescription, sensitive eyes or conditions like astigmatism or dry eye syndrome, when they’ll be worn, where they’ll be worn, and cost. The other, possibly more important, are the health factors. Daily activity, as well as, one’s own tears can leave residue on contact lenses. This residue can include common things like dust, as well as, the proteins, calcium, and lipidspresent in tears. Although cleaning lenses may reduce these deposits or residues, it’s not always completely effective. For this reason, many patients prefer the daily disposable contact lenses both for hygiene and comfort. Disposing of contacts and all of the stuff that has collected on them throughout the day is much more convenient than the alternative, cleaning, soaking and storing. Daily disposable contact lenses may also give the benefit of less exposure to irritations and infections of the eye.


With so many choices available in the contact lens market there seems to be something to meet just about everyone’s needs. Remember to consider all the factors when working with your doctor in order to ensure the right fit for and for the health of your eyes.

The Importance of Protective Eyewear While Playing Sports

The Hargrave Eye Center’s latest post:

While it is important to protect your joints, arms, legs, and extremities during sports, it’s also important to protect your eyes. The eyes are a complex organ that enables you to see the world around you. Navigating would be difficult if not impossible, without the ability to see. There are many reasons why you should keep your eyes safe in general, but they’re even more crucial while playing sports.

The Importance of Healthy Vision

Your eyes take in visual information from light in order to help you make sense of your surroundings. Even though this information is processed in the brain, you wouldn’t be able to see without your eyes. This organ is made of various parts that work in conjunction to keep your eyes healthy and provide your brain with visual cues from light:

  • Conjunctiva: The conjunctiva serves to lubricate the eye and protect it from dust, debris, and microorganisms. A common ailment of the conjunctiva is known as conjunctivitis. It’s caused be either viral infection, bacterial infection, or allergens such as pet dander. Bacterial conjunctivitis is the most damaging to the eye if left untreated.
  • Sclera: The sclera is made of small fibrous collagen that serve to maintain the shape of the eyeball. The sclera helps to protect the eye from external trauma such as laceration or rupture. It also serves as an attachment point for the muscles that control eye movement. External trauma to the sclera can often result in retinal detachment (separation of the retina from its connective tissue).
  • Cornea: This clear front surface of the eye allows light to pass to the retina and is responsible for approximately 65-75 percent of the eye’s focusing power. Damage to underlying levels of the cornea can cause permanent scars that affect vision.
  • Lens: The lens is composed of flexible tissue and is responsible for 25-35 percent of the eye’s focusing power.
  • Iris: The iris is composed of connective tissue and muscles that control how much light enters the eye. A common ailment of the iris is synechia. Synechia happens when the iris adheres to the cornea, and can be caused by trauma to the eye.
  • Retina: The retina is a sensory membrane that lines the back of the eyeball. It contains specialized cells that gather information from light and transfers it to the visual centers of the brain.

Any injury to one or more of these parts of the eye can have an affect on your vision and quality of life. Therefore, it is of the utmost importance to wear protective gear for your eyes while playing sports.

Choosing Protective Eye-Wear

Choosing the right protective gear is just as important as deciding to keep your eyes safe. There are plenty other body parts injured in sports, but the eyes can be an overlooked area. Flying objects, pokes, jabs, or elbows to the eye are something that is best avoided. A racquetball can move between 60 and 200 mph during the average game. With that in mind, it’s best to go for highly durable polycarbonate eye-wear. Most protective eye-wear is made of polycarbonate, which is shatter-proof and offers UV protection. There are also protective coverings fitted to helmets for sports like paint-ball and motocross. Whichever sport you play, there are plenty of options available.


No matter what sport you play, it’s a wise decision to keep your eyes safe. An injury to them can easily cause a loss of vision in one or both eyes. This can dramatically affect your quality of life, so remember, safety first.

How Smartphones Can Detect Eye Disease

The Hargrave Eye Center’s latest post:

The importance of smartphones is undeniable for today’s society. It would be hard to find a person without a smart device, and it easy to see why since these devices have become quite useful. For example, there is a new app that has just been developed meant to detect an eye disease.

How Does This App Work?

It may sound incredible to hear that an app can be an effective eye tester, but a Swedish study shows that the results of this app were more precise than regular vision tests.

As people age, the eyes begin to change, and some of these changes can end up hurting one’s vision. Sometimes, the changes are subtle but other times the changes are problematic enough to worry anyone who is concerned about the health of their eyes.

One thing that can begin to affect an elderly person is macular degeneration. This issue can distort vision so much that it could make everything blurry given enough time. It is this problem that Swedish scientists were trying to address when they first attempted to create the smartphone application that is going to help test a person’s eyes for this problem.

The app can test a person’s eyes for this issue, record the results, and send the findings to the appropriate eye specialist for further analysis. The app is quite interesting, and it is called MultiBit.

It asks the user to read letters out loud when they are presented. The trick is the letters start to fade for the user, and it is up to the user to figure out what the letters are as the written letter starts to lose focus.

It should be pointed out that there are more than just one of these apps being introduced to the public; for example, there is the Celego, just to name one more. People sometimes have a hard time going to their eye specialist, even though it is important. This app is going to be a great tool for preventative eye care and diagnosis, which is pretty exciting because it means that each individual has an opportunity to care for their eyes more effectively. Then, they can go to their eye specialist for further assistance.
