Coloured Contact Lenses

While fashion sunglasses are commonly considered a fashion accessory, they are actually intended as a protective device. These fashion accessories are available in different styles that provide something for just about every budget level. Many people use these fashion accessories as protective devices as well.

When purchasing Tom Ford sunglasses there are some points that you should keep in mind. The most important factor is the health condition of your eyes. For those people who wear glasses to help see or even just to read, it is often important they do not go outside without protection from the sunlight.

The prescription versions of these glasses appear similar to other sunshades, but they actually contain prescription lenses. In fact, these are typically the same prescription as your regular glasses, but are capable of blocking the sun since they are tinted. The amount of tint on these lenses may vary based on the desired amount of protection from UV rays.

In many cases if you are purchasing prescription glasses you may be able to get a second set that have tinted lenses. There are many eyeglass retailers that offer a free pair of tinted lenses when you buy regular glasses. If you buy prescription tinted lenses separately you will probably pay the same price as your regular lenses.

The lenses in these glasses often offer a variety of sun protection, referred to as the amount of ultra violet (UV) protection. The amount of UV protection can be very important, considering the fact that these lenses are really protection from the sun and not just a fashion accessory. Sunlight can be hazardous to the naked eye and this is why these accessories were created originally.

The sun’s rays have the ability to cause damage to the eyes and may affect your vision in the long run. The cheap glasses found in convenience stores and other such retailers do not really provide adequate protection from the sun. Prescription lenses are designed to provide sufficient protection.

Your primary concern when shopping for sunglasses should be protection, then you can worry about fashion. These glasses have become so popular that there is something to satisfy just about every taste. The best glasses make you look good and allow you to be able to see well.

One way to decide on style is to select a frame color that accents your skin tone. While silver frames may look good on some people, they do not necessarily look good on everyone. There are also a wide variety of colored frames and you will find that selecting a colored frame is strictly matter of personal taste. You may also want to select the shape of the frame based on the shape of your face.

While Tom Ford sunglasses are often considered a fashion accessory, sport sunglasses are foremost a protective device. They should help you see better in bright conditions and also protect your eyes from harmful UV rays. If you wear prescription eyewear then you may be able to save money on prescription sunglasses by purchasing them both at the same time. Your primary concern should be the amount of protection provided, with how they look as your second consideration.

It may sound like science fiction but more and more people are opting to bin their reading glasses in favour of having artificial plastic lens implants inserted into their eyes instead. The procedure is becoming increasingly popular, particularly amongst middle aged people wanting to avoid the onset of presbyopia, or the deterioration of sight related to age. It sounds too good to be true, surely if it really works it could be the end to all our vision worries?

The idea of having your natural lenses removed from your eyes and replaced with a piece of plastic might not be one for the squeamish, but in fact the procedure does work surprisingly well. The number of patients opting for the surgery has doubled since 2004, with most people reporting that the implants have made a huge difference to their sight, often meaning they no longer need to wear their prescription glasses at all.

So how does it actually work? Well, the natural lenses in the eye can often stiffen with age, losing their ability to bend and focus properly. The lens implant procedure removes the natural lens from the eye and replaces it with an Intraocular lens, which uses the muscles of the eye to mimic normal lens movements and enhance the eye’s optical abilities. The procedure takes less than half an hour – the patient is given a local anaesthetic and then a small incision is made, the old lens removed and the new one inserted.

Lens implants as a preventative measure are not yet available on the NHS and the cost of the private procedure is not cheap, usually falling somewhere between £2,500 and £3,000 per eye. But when you think about it, being able to see both near and far without being dependant on glasses, escape from the discomfort of wearing them, or even being able to wear stylish designer sunglasses without having to worry about buying prescription lenses could actually be worth it!

So many of us these days have vision problems are need to wear glasses or corrective lenses. Recent research has showed that as much as 50 per cent of the US population is short sighted. I certainly see a lot more kids at school these days with glasses than there were when I was growing up. Because of all of this it is more and more important to look after your eyes and make sure there’s no way your lifestyle could be making your vision worse. So I decided to share my top 5 tips for healthier eyes:

Get your eyesight checked regularly.

It is advisable to schedule a visit to your optician at least once every year as some eye problems can often go unnoticed until it is too late. Getting regular eye tests can prevent the need for costly corrective treatments in the future so make sure you always follow your optician’s advice – if they say you need prescription glasses, start wearing them straight away.

If you need glasses, wear them!

It doesn’t matter whether you think they look good or not, if your optician has told you that you need glasses then you need to be wearing them. Not wearing your glasses can damage your eyes further and will only mean that you will need a stronger prescription later. If you don’t like the way they look shop around, there are hundreds of frames available and you’re sure to be able to find something that will suit you.

Maintain a healthy diet for your eyes

Research has proven that certain vitamins and nutrients are good for your eyesight, so making sure that your diet contains plenty of vitamins A, C and E, folic acid, selenium and zinc could help prevent future vision problems. If your prescription is very low (-0.25) it’s possible that your vision problems could actually be corrected by switching to a diet rich in these important nutrients.

Always make sure your eyes are protected from the sun

It may sound obvious to say that UV rays can cause severe damage to your vision, yet hundreds of people still allow this to happen every year. Sunglasses are an absolute must for going out in the sun, whether you have existing vision problems or not. With an endless range of designer sunglasses on the market, it’s easy to find a pair that you like and that will give you the all-important protection you need.

Give your eyes regular breaks!

If you spend a lot of time at your computer, it’s important that you give your eyes regular breaks. Just closing your eyes or focusing on an object in the distance for 10 seconds at least once an hour can make a really big difference and helps to prevent headaches and vision problems associated with prolonged use of a screen. Don’t forget these problems don’t just happen at work, the same applies to watching TV and playing video games too!

After years of being told that video games are bad for your health and especially your eyes, a new study has proved that in fact playing some games may actually help improve your vision, and could even prevent you from needing glasses in the future. The study, conducted by the University of Rochester, demonstrates that regularly playing certain games improves a person’s contrast sensitivity function, or their ability to distinguish easily between different shades of grey. But does that really mean your eyesight has improved?

Shades of grey might not sound all that ground-breaking, but contrast sensitivity is one of the most commonly and easily damaged functions of the human eye. People who suffer from low contrast sensitivity find it harder to see at night or to pick out small details like spots on clothing, and often the only way to treat the problem is with increasing strength prescription glasses or eye surgery. It’s now believed that computer games could be used to train the eyes to develop these skills, and that it’s possible the same method could even be used to treat people who suffer from Amblyopia or ‘lazy eye’, a condition that affects the brain’s ability to correctly register signals from one eye.

But not all video games are thought to have this effect. The study compared two different types of games by testing young adults who did not normally play games both before and after a period of playing them regularly. The results suggested that subjects who played first-person shooter or action games like Call of Duty showed a 43 per cent improvement on average, whereas those who played non-action games such as The Sims 2 showed hardly any.

So if gaming could help us avoid eye problems should we all be rushing out to buy an XBOX with as many action games as we can find to ensure that our designer sunglasses will remain our only visual aids far into our future? Well, no. For a start the study makes a point that not all action games will work, in other words, most of them probably won’t. Not to mention the fact that although these games may help develop some areas of your sight, it’s still not advisable to be sitting in front of a screen for long periods of time, or to allow computer games to replace other activities necessary to staying fit and healthy. In theory it’s a nice idea, but it’s important not to forget that it’s just as possible that video games could well be harmful in other ways.
