Three Common Types Of Cataracts Explained

The lens of your eye is located behind your iris and is clear in a healthy eye. When you develop a cataract, the lens clouds over and appears opaque. Left untreated, a cataract can cause complete loss of vision in the affected eye. The clouding occurs as a result of a protein in your lens changing its structure and clumping together, which blocks light from reaching the retina at the back of your eye. Here’s an overview of three common types of cataracts and the treatment process: 3 Common Types Of Cataract If your optometrist diagnoses you with a cataract, it’s likely to be one of these three types: Nuclear – This is the most common type of cataract. It’s associated with ageing, which causes the protein in the middle of your lens to begin to break down. In the early stages of development, your ability to see close-up objects may improve as your eye’s focusing capability changes. However, this is a temporary perk of a nuclear cataract. Cortical – A cortical cataract diminishes your ability to see near and distant objects clearly. It begins to form around the outer rim of your lens and gradually works its way inwards. This type of cataract is a common complication of poorly-controlled diabetes, as high levels of sugar alcohol in your lens can damage the delicate cells of your lens, which encourages the breakdown of protein. Taking steps to keep your blood sugar levels under control reduces your risk of developing a cortical cataract. Subcapsular – This type of cataract develops on the back of your lens and early symptoms include blurred vision and increased sensitivity to light. Diabetes is also a risk factor for the development of a subcapsular cataract, but it’s commonly associated with prolonged use of prescription corticosteroids. Therefore, those with an inflammatory autoimmune disease, such as rheumatoid arthritis or Crohn’s disease, are at in increased risk of developing this type of cataract. Treating Cataracts The only way to get rid of a cataract is to have it surgically removed. Cataracts tend to worsen over time, so prompt treatment can prevent you experiencing further discomfort, but some people do choose to wait and see how quickly their eyesight is deteriorating before having surgery. If you’d like to take this approach, it’s best to have regular eye exams as changes to your vision may not be immediately noticeable to you. Cataract surgery involves removing the lens with a small device that breaks it down using ultrasonic waves. The lens pieces are then suctioned out of the protective lens capsule and replaced with an artificial lens. You can opt for a plain lens or one with focusing capability. If you normally wear glasses, you will still need to wear them with a plain lens, but you may not need them if you select a lens that enables you to better focus on near or distant objects. The procedure can be carried out under local anaesthetic and you should be able to go home the same day. If you’re experiencing visual disturbances or notice any changes to the colour of your eyes, schedule an eye exam as soon as possible.

How to Pick the Perfect Frames after Just a Quick Look in the Mirror

Posted by on Jul 21st, 2015 in Uncategorized | Comments Off on How to Pick the Perfect Frames after Just a Quick Look in the Mirror

If you’re planning on picking up a new pair of frames — or even your first pair of prescription glasses — then you’re probably wondering which type to go for. Most opticians have a vast array of styles on offer, so it can be tricky to narrow it down to just a few. Luckily, there’s a simple trick. Most of the time you’ll find that the best glasses for you are the ones which contrast with the shape of your face. Everyone is a little different, but here’s a guide to the six basic face shapes and which sort of frames tend to work with them. Round Round faces measure almost the same across as they do up and down, and they are characterised by soft, curved lines. Contrasting with a round face is easy, just find narrow, angular frames which are more rectangular than normal. They will make your face seem thinner and more defined. Oval Oval faces work well with glasses since their proportions are more balanced, with the length of your face measuring close to double its width. It’s also the only face shape which tends to work better when you use complementary instead of contrasting frames, so look for ones of a medium size which are neither too angular nor too rounded. Oblong Oblong faces are slightly longer than they are wide, with a straight cheek line and a long, narrow nose. If you want to make an oblong face look a little more balanced, try a pair of frames which are both wide and deep, with a low bridge to help shorten the nose. You can also experiment with colour accents and decorative details on the upper part of the frame. Point-Up Triangle If you have a relatively narrow forehead with wide cheeks and chin, you’ll usually want to emphasize the upper third of your face in order to balance things out. Frames which are brightly or heavily coloured are a good idea, as are those wider at the bottom. Rimless or semi-rimless frames can also work. Point-Down Triangle The opposite of the point-up triangle, naturally, will be narrower at the bottom than it is are the top — often referred to as heart-shaped. You want to maximise the width of your face, so pick frames which are wider towards the bottom, and try to avoid any with bold, bright colours. Square If you have a square face, you’ll enjoy a strong jaw line, a broad forehead, the lines of your face will be quite angular and the width and length will be about the same. Make your face look a little bit longer and softer by picking a pair of frames which are relatively narrow, with an oval or round shape. After a glance in the mirror, you should have a basic idea of which frame shape will make your face look its best. You’ll now be able to quickly narrow down your options when you start shopping, and find the perfect pair for...
