Caring for Your Eyes

Proper eye care is just as important as taking care of the rest of your body. Eye care is more than visiting the eye doctor for regular examinations. Rather, good eye care involves caring for the entire body and staying away from bad habits that may actually have an affect on the eyes. Let’s take a look at what’s involved in good eye care and also chat about how to order bifocals online.

Diseases of the eye are more common that you would think. Further, as people age they become more susceptible to eye diseases. That’s why regular examinations by the eye doctor are so critical to the idea of good eye care. An eye doctor can run special tests to see if there is any indication or the appearance of eye diseases and disorders. Diseases and disorders include, but are in no way limited to cataracts, conjunctivitis, diabetic retinopathy, dry eyes, glaucoma, orbital tumors, and blindness, congenital diseases of the eye and more.

Yet, it is also important that a person takes care of their body and remains as healthy as possible. Why? Well, beyond the benefits one derives from being healthy some health conditions actually affect the eyes. For instance, vitamin deficiencies can affect the sight. A lack of vitamin A can even cause night blindness. In fact, it is a known fact that well over ninety percent of all cases pertaining to the onset of blindness can be attributed to other diseases. Diabetes is another disease that plays a significant role in the occurrence of blindness. Therefore, it becomes increasingly important for people to maintain their overall health in the best way possible and to manage existing conditions if at all feasible.

Bad habits are something that should also be avoided if one wants to properly care for one’s eyes and maintain good eye health. Smoking can cause significant damage to the eye and can eventually result in blindness. For instance, smoking can be the cause of what is referred to as Macular degeneration which creates a blind spot in the eye or eyes.

Other problems that occur with the eyes are caused by accidental injury. Say for example, you are working in a garage welding and item and you don’t wear goggles during the process. Suddenly you find that a spark flies up and burns your eye. Or, if you are working with hazardous chemicals and chemicals get in your eyes – had you been wearing goggles you may have been able to avoid injury altogether. Thus, safety and safety practices are imperative to maintaining good eye health.

As you can see, taking care of your eyes involves more than a yearly visit to the eye doctor. Instead, you need to take care of your overall health, you need to avoid bad habits and you need to practice safety measures to ensure good eye health. In the end, you will be rewarded with the continued gift of sight, well into your golden years!

Presbyopia is a vision condition in which they eyes are not able to focus clearly on near objects. It usually begins after the age of about forty when the lenses in the eye start reducing in flexibility. Presbyopia affects around 90 million adults in the USA alone and about one in four patients passing through an optometrist’s door will suffer from it.

Symptoms of presbyopia include difficulty in reading, difficulty in seeing in low lighting conditions and, occasionally, headaches.

Traditionally these vision problems were addressed with the old-fashioned reading glasses. Or existing eyeglass wearers could opt for bifocal eyeglasses. However the use of modern contact lenses for use with presbyopia has some distinct advantages beyond their cosmetic appeal. For example they can be well suited to other aspects of a wearer’s lifestyle such as sporting activities, exercising or using a computer.

Recently, contact lenses for correcting presbyopia have become available in more convenient types such as disposable or frequent replacement varieties. Today these are very popular lens types providing obvious benefits for the wearer.

HOW CONTACT LENSES CORRECT PRESBYOPIA

From a technical perspective, there are three distinct ways by which contact lenses can be used to correct presbyopia, each with advantages and disadvantages for particular types of patient. But the important thing here is that there is a choice and each wearer is likely to find one method best suited to their unique situation. The different contact lens methods are as follows:

MONOVISION

The monovision technique involves using in one eye a lens for seeing near objects and in the other eye a lens for seeing distant objects. Many people find that monovision works very well for them. It relies on the brain’s ability to selectively process and combine information from the best available sources in order to provide the clearest possible vision. In some instances, the optometrist might employ a bifocal lens in one eye and a normal distance lens in the other. The main problem associated with monovision is the apparent loss of depth of vision for some patients.

BIFOCAL CONTACT LENSES

As with traditional bifocal eyeglasses, each lens in bifocal contact lenses possesses two powers – one for seeing near objects, the other for distant objects. Some types of bifocal lenses when magnified look a little like a bull’s eye with an central inner zone surrounded by the outer zone. The drawback to this type of lens is that in certain conditions of reduced lighting, the vision might not always be as sharp in certain areas.

MULTI FOCAL CONTACT LENSES

Multi focal contact lenses work very much like the progressive lenses for eyeglasses. These lenses possess several zones of differing power in order to assist the eye gradually as it changes its focus on different objects at different distances. Therefore these lenses are designed to function well for seeing near, intermediate and distant objects. Their drawbacks are typically the same as for bifocal contact lenses, with occasional loss of visual acuity.

Bifocal lenses are available in two basic design types, ‘Translating’ and ‘Simultaneous’, the essential characteristics of which are as follows:

TRANSLATING BIFOCAL LENSES

Another name for the translating lens type is an ‘alternating lens’. Gas Permeable bifocal lenses are regularly of this type. Their usage is very much like that of traditional bifocal eyeglasses. The wearer will look through one zone for distance vision then ‘translate’ to look through the other zone for near vision. Both zones aren’t looked through at the same time.

SIMULTANEOUS BIFOCAL LENSES

The majority of soft bifocal contact lenses on the market are of the ‘simultaneous’ type. As the name implies, with simultaneous lenses the wearer actually looks through the various powers of the lenses at the same time. What happens is that the brain steps in and ‘suppresses’ the power or powers, which aren’t needed at that particular time in order to see clearly. There exist further subdivisions of this lens type, but we won’t go into the details in this brief overview.

As with all contact lens selection and wear, choosing the right type of bifocal lens depends equally as much upon the wearer’s unique lifestyle as his unique vision characteristics. For example a patient who regularly undertakes sporting activities will have different needs from one who only needs to wear them socially or for use at work.

However, the success of adopting bifocal contact lenses relies very much on the expectations of the wearer who should realize that, almost by definition, bifocal lenses are very much a compromise and that he or she is never going to regain the acuity of vision in all environments that they had when younger. In most cases this is perfectly acceptable and bifocal lenses have now earned their place in the optometrist’s ever-expanding repertoire.
