Soft contact lenses have long been a favorite by those seeking instant comfort and ease of use. A soft lens is typically larger, with the edges extending out to the white of the eye, beyond the cornea. This makes for a very comfortable lens that can be worn for many hours. One of the main drawbacks with soft lenses is that they provide soft vision. In short, the lens material is soft and relies on tears to maintain it’s consistency, the vision is prone to intermittent blur and general fuzziness.

Hard or gas permeable contact lenses take the cake when it comes to best achievable vision. Because the material is more firm, the lenses maintain their sharp optical acuity. There has never been a question that best visual acuity via a contact lens is achieved with a gas permeable lens. So what has been the drawback with conventional gas perms? The answer is comfort. Gas perm lens wearers need to go through a short adaptation period in order for the lenses to become comfortable.

Recently, hybrid contact lenses have been making a huge splash in the lens world. Hybrid lenses are composed of a gas permeable

• LASIK: Laser assisted in situ Keratomileusis – LASIK is a refractive laser vision correction procedure. It involves the use of a laser to reshape the cornea. A flap is cut in the outer cornea and is lifted out of place while the laser is used to reshape the cornea. The flap is then set back into place after the reshaping is complete.
• PRK: Photorefractive keratectomy- PRK was the earliest form of laser vision correction. PRK is different from LASIK because instead of cutting a flap in the outer cornea, the outer cornea is actually removed. This means more pain and a longer healing time, but less chance of problems during healing with the cornea not healing in place correctly.
• LASEK: Laser-Assisted Sub-Epithelial Keratectomy – Like PRK LASEK is different from LASIK because it removes the outer cornea, not cuts a flap in it. However, with LASEK the outer cornea is dissolved with a chemical solution not cut off as is done during PRK.

The main objective in all types of laser vision correction is to reshape the cornea. It is the misshapen cornea that causes vision blurriness. As you can see the differences in each

First off, let’s see if we can clear up some of the confusion and get a clearer perspective on what the word “dyslexia” really means.

It is important to understand that there are two different schools of thought, two different ways in which the word “dyslexia”itself is used. The two different meanings of dyslexia are:

• In the pure academic sense the word “dyslexia” has a literal meaning based on the etymology of the word itself. From its parts, ‘Dys’ means wrong or problematic (for example, as in ‘dysfunctional’) and ‘lexia’, means pertaining to words and letters. So literally, ‘dys’-‘lexia’ refers to problems with words.

In this sense, anyone who has a problem with reading, for whatever reason, has dyslexia.

• There is a wider use and application, used by parents of dyslexics and by dyslexic adults. In the applications sense, dyslexia refers to a range of symptoms that includes problems with reading, writing and spelling plus other problems such as hearing difficulty, poor memory and a lack of physical coordination.

And so, as you can see, the exact meaning of “dyslexia” depends on who is speaking and the context in which the term is being used.

There are several causes of blurry vision. One of them is a need for eyeglasses. If a patient suffers from myopia or hyperopia, glasses may be needed. In nearsightedness and astigmatism, objects from a distance may appear blurry but nearby objects may be clear. The blurring that happens may be more acute at night or patients may experience seeing ghostly images or double vision. Usually, those in the mid-40s develop a need for reading glasses. Another cause of blurry vision could be cataract. Most people think cataracts only occur in older people, but it can also occur in younger people. Cataracts commonly occur in people who are over 50 years of age. Symptoms that accompany blurry vision include problems with seeing at night, glare problems and color problems. While this is a cause for concern, cataracts do not cause pain or the feeling that something is stuck in the eye. Other causes may be macular edema, macular degeneration, optic neuritis and diabetes.

Blurry vision in one eye can also be traced to flu. When you’re sick, your immune system is down so you are most susceptible to infections. If you happen to be coughing as well, you
