Presbyopia is one of the most common conditions affecting senior citizens nowadays. Presbyopia is caused by the eye’s inability to focus in old age, especially with near objects. Thus, blurring of vision occurs, more prominently in the dark. Presbyopia typically presents with blurring of vision when looking at near objects, requiring patients to hold objects far away to be able to see or read. Some people who are nearsighted before they are 40 years old find that their nearsightedness is actually surprisingly advantageous, allowing them to see more clearly when presbyopia starts to set in.

Previously, presbyopia was treated with corrective lenses that are able to compensate for the loss of the eye’s ability to focus effectively. If the patient has an additional refractive error, convex lenses can be used. If corrective lenses aren’t enough, senior citizens can be given a prescription for bifocals or multifocals. The downside to the use of these lenses is that they can occasionally distort the images that you see. Also, the prescription of the glasses changes constantly, as presbyopia progresses.

Senior citizens who would rather not use eyeglasses or contact lenses can opt to undergo laser eye surgery in order to correct presbyopia. Typically, LASIK eye surgery is used in correcting presbyopia. Conventional LASIK eye surgery, however, can further aggravate the senior citizen’s inability to see things up close. Thus, instead of employing the typical LASIK eye surgery, a specific approach, known as monovision, is used.

The monovision approach was initially employed using contact lenses. One contact lens corrects near vision in one eye while the other contact lens corrects distance vision in the other. In time, a more permanent form of monovision was developed. Instead of using contact lenses, laser can be used to permanently change the vision of the eye. One eye can be permanently corrected for near vision while the other eye is permanently corrected for distance vision.

Some people find it very hard to adjust to monovision. Before undergoing monovision laser eye surgery, it is a good idea to first try with contact lenses. This will help you determine whether you can handle permanent monovision or not. If you can’t, laser eye surgery may not be for you. You may want to consider other forms of treatment for presbyopia. These treatments include the use of intraocular lenses and novel techniques, such as the use of scleral expansion bands and the surgical reversal of presbyopia, or SRP.

Your eyes are the most prominent feature of your face. They are very expressive and tell a lot about the person. The beauty of eyes is its mystery and they are a window to the soul. Losing your eyesight at a young age is disheartening and weak eyes are a very wearisome indication of old age.

Lasik is abbreviation of Laser Assisted in situ Keratomileusis, used to cure problems like astigmatism, hyperopia and myopia and is performed by ophthalmologists and is a type of a retractive laser eye surgery.

This lasik laser eye treatment has been extensively used by surgeons as this process makes the patient feel comparatively less pain and is also able to recover much faster than by following the normal procedure of surgery. This is used to cure problems of long and short eyesight so it can act as an alternative to wearing contact lenses or even glasses.

The method of Lasik laser eye treatment is carried out in several steps. These steps are:

- If the patient wish to have the laser operation done then that patient have to stop wearing hard contact lenses at least six weeks and in addition of multiple of six weeks for the number of years the person has worn the lens. Cornea of the patient also has to be examined before the operation.

- This lasik laser eye treatment operation is performed through giving the patient anesthesia drops in the eyes. During the operation the patient is awake. In the operation first the flap is created for the corneal tissue further to remodel the cornea under that flap. After the above steps the created flap is then positioned to proper place.

There are various types of problems that a person might have to face after the lasik laser eye treatment like a person’s eyes might become very sensitive to the bright light. Under such case a person might not be able to see anything where there is presence of bright light in the background.

A person might even develop problem of vision loss, which is further devastating as this problem cannot be solved, not even with another surgery or glasses. A person may even have a blur vision.

For the people with normal eyesight it is always so very easy to go wherever you want or do whatever you want. Nevertheless, if you have power in your eyes then you have to make adjustments with the different situations or else you will have to be well prepared for feeling free and comfortable in different adverse situations.

In this article, we will discuss the preparations that can be made for the people using looking glasses to work on computers comfortably and with ease. Before we go in the details of preparations let us know the basics of aided eyes that can work properly only with the help of pairs of optical lenses, commonly known as spectacles, looking glasses or eyeglasses.

Eye Problems by Aging:

Human beings feel prominent changes in proper functioning of their eyes with the passage of time and because of their aging process. Our eyes develop difficulties in seeing / resolving the objects as we grow older. The common eye problems are commonly called ‘shortsightedness’, ‘long-sightedness’ and ‘axis’. A brief detail of the same is described as follows:

1. Shortsightedness:

In case of Nearsightedness (Myopia), we feel problems in seeing objects at a short distance. That means we find problems in reading books, seeing photographs, working on computers while looking at the keyboard and reading the characters on the monitor. For correcting this problem, cylindrical lenses are prescribed and with the help of that, we can see / resolve the objects close to our eyes.

2. Long-sightedness:

In case of Farsightedness (Hyperopia), we are not able to see / resolve object / characters at a long distance. That means we find difficulties in watching TV or a movie in a cinema hall or even in looking around while moving outdoors. For correcting this problem, cylindrical lenses are prescribed and with the help of that, we can see / resolve the objects situated at a farther distance from our eyes, say at 100 feet or more.

3. Astigmatism:

The third common problem with eyes is ‘axis’ (astigmatism). In this case, we see a deformed image of the object. For example, a circle might not look like a true round circle. It may also appear as if an image of a circle is appearing on another image of the same circle. For correcting this problem, cylindrical lenses are prescribed for adjusting the axis and with the help of that, we can see / resolve the objects in their true shape and sharpness.

Usually, after crossing the age of 35 or 40 people use to say that their eyes have become weak. In fact, the eyes develop certain changes in their anatomy that eventually result in developing ‘axis’, ‘shortsightedness’ or ‘long-sightedness’ rather than losing their strength or becoming weak. The eyes continue to be strong and healthy with aging, nevertheless, they developed different powers that result in difficulty in seeing / resolving objects. The remedies have already been discussed along with the problems in the preceding paragraphs. Presently the following visual aids are widely used for correcting eye problems and the resultant visual discomfort:

• Bi-focal spectacles:

On developing these eye problems, we usually go for eye tests, get a pair of glasses for, and use them as and when required. Most of us are prescribed with bi-focal spectacles that have upper portions of the lenses for farsightedness and a small portion of lenses for reading purpose. The opticians also provide axis correcting cylindrical characteristics in such glasses if required. This combination of glasses in the form of bi-focal variety is the most popular visual accessory in the modern times.

• Progressive Lenses:

In the case of bi-focal lenses, the ocular glasses are divided into two portions. The upper portion for long-sightedness and the lower portion is dedicated to reading purposes of for resolving closer objects as in case of inserting thread in the eye of a needle or doing other similar jobs. On the other hand, the lenses in case of progressive focusing the lenses are provided desired curvatures and optical surfaces in a gradual and smooth succession. This hi-tech optical process eventually produce an end-product that will suit for resolving / seeing everything, of any size and at any distance. That means that by putting on a pair of glasses with progressive lenses we would be able to have sharp and defined vision without changing, lifting or tilting our glasses. With these glasses on we would look around like any other person with normal vision.

How to Work On Computer with Glasses On:

We have discussed on various eye problems we face due to aging and the accessories we use for their correction. Now let us come back to our main discussion about the best ways that could be followed for working comfortably on computers with our eyeglasses on. There are two ways to work comfortably on computers with aided eyes.

• The first way is to go for getting a dedicated pair of glasses made by any optician in your neighborhood. Carry a printout of texts of ‘Arial’ fonts of different sizes viz 10, 12, 14 and 16 to the optician. Ask him to make a dedicated / customized pair of glasses for clearly seeing / resolving all the fonts on you printout from a distance of 20″ to 26″. The optician will keep your printout at the desired distance and will follow the exercise of permutation and combination of different glasses for finding out the right powers for each of your eyes and finally make a pair of customized glasses for your use on computers. This pair of glasses will also be useful while shaving or doing makeup.

• The second alternative is to go for a pair of progressive glasses for which you need not go for any customization or a spare pair of glasses exclusively for use on computers. A pair of progressive lenses will serve all purposes you come across in your day-to-day life.

The only reservation with progressive glasses is that they are too costly. I think the cheapest spectacles with progressive lenses might cost 2000 rupees (India) and whereas the simple / common / normal customized spectacle for computer will cost as less as below 200 rupees (India). Now it depends on our resources and our way of thinking for selecting any one option out of the two described above.

Acuvue contact lenses are top sellers among the numerous lens brands on the market. One of the varieties of Acuvue products is Acuvue toric contact lenses. This range is particularly designed for patients who have astigmatism. Acuvue toric lenses offer a good solution for this special group. As widely known, the eye of an astigmatic patient has two different prescriptions. In this case, special lenses called toric contacts are needed because they can offer two different powers in a lens. Regular spherical contact lenses have only one power all around the lens. One requirement of toric contact lenses having two powers is that they can not rotate should patients want to get best vision correction.

One product from Acuvue for astigmatic patients is Acuvue Advance for Astigmatism. These lenses are disposable ones that can be discarded after a week or two. Johnson & Johnson uses special technologies which take use of the wearer’s blink with the shape of the lenses. In order to keep the lenses stable or avoid lens rotation, the blink and the lens shape work together to keep the lens in position. These lenses are not daily disposable that they can be reused after adequate cleaning.

People bothered by dry eye can choose Acuvue Oasys for Astigmatism. This special lens option suits astigmatic wearers who spend a lot of time outdoors in the wind or in a dry climate. Using Acuvue Oasys for Astigmatism lenses, wearers can nearly be free from dry eye because these lenses are made to be extra moist. In toric technology, this variety is similar to the Advance design. But they differ in moisture content.

The aforementioned two varieties of Acuvue toric contact lenses really help patients with astigmatism a lot. As a leading lens manufacturer, Johnson & Johnson do provide comfortable lenses for all of its customers. In general, Acuvue toric contact lenses are more expensive than regular ones. But discounted ones are available online.
