Wearers of glasses can cut their expenses by buying them online, a finance writer has said.

In a MoneyWeek article, Ruth Jackson found that glasses are cheaper when they are bought over the internet as opposed to traditional bricks-and-mortar stores.

She warned, though, that consumers must be careful to get their prescription correct when they buy glasses online, as companies do not need to give refunds once the product has been delivered.

In addition, users will need to provide their pupillary distance, preferably by having an optician measure it.

Ms Jackson also pointed out that people who work with computers may be entitled to have their eyes tested free of charge.

Rick Broda wrote on CNET News” Cheapskate blog that buying glasses over the internet was a cheaper option.

He admitted that this meant they could not be tried on first but said that people in the US could pay “a fraction” of what it would cost to buy them from more traditional outlets.

Tips on whether laser eye surgery is right for you

Tips on whether laser eye surgery is right for you

Contact lens wearers and other people considering laser eye surgery have been issued with a number of tips on what makes the ideal candidate for the treatment.

The American Academy of Ophthalmology, in cooperation with the US National Library of Medicine, states people should be at least 18 years old, but also notes in some cases a child with one very nearsighted eye and one regular one could benefit from the intervention.

Women thinking about the treatment should not be pregnant or nursing when they have the procedure carried out.

In addition, people should ensure they are in good overall health, without chronic conditions such as glaucoma, cataracts, diabetes, rheumatoid arthritis or lupus, web resource WFMJ.com reports.

Concluding, the resource states individuals considering undergoing the surgery should have healthy eyes with vision prescriptions that are relatively stable.

Continuous wear contact lenses can be a viable option for those who choose not to go under the laser. They allow more air to reach the eye and can therefore be worn overnight.

Wearers of extended wear contacts can benefit from immediate and sharp vision with the flexibility of a changeable prescription later down the line.

Contact lenses can also involve a lower level of risk and hassle, as they only need changing as little as every 30 days.

Continuous wear lenses include brands such as Purevision or AirOptix Night & Day.

How to deal with ageing eyes


Image
 
As we age, our eyes age with us. This can bring a number of sight issues to the fore. Luckily, however, there are options available to correct such vision problems.

Dr Ella G. Faktorovich addressed the issue in the San Francisco Chronicle recently. She explained how the lenses inside the eyes become more rigid as they grow older and how this can make it difficult to look at things up close, making reading harder than it was before.

Surgery is not necessary. Dr Faktorovich explained that people can wear contact lenses to solve this problem, wether monovision or bifocal ones. Monovision contact lenses involve wearing one lens for distance viewing and one for focusing on things up close.

However, you may also be able to have your eyes” natural lenses replaced in a refractive lens exchange procedure, correcting near and far focusing.

It is known that dry eyes become more likely as one grows older. NHS Direct gives information on this, explaining that, while it is a common ailment, people over 60 are more likely to develop it. Furthermore, women are more susceptible to it than men.

The complaint can vary in its severity. While it does not usually cause serious harm, NHS Direct warns that it is possible to suffer eye scarring if the case is extremely bad and is not treated. Dry eyes cannot be cured but they can be relieved through the use of drops. It may even be possible that surgery is needed, but this is unusual.

Age-related macular degeneration (AMD) is another issue. The Royal National Institute of Blind People (RNIB) notes that while it is a common cause of sight loss, it is very rare that it leads to total blindness.

Although it is an age-related ailment, there are still measures one can take to protect against it. The RNIB explains that several studies have suggested it is linked to smoking, too much exposure to the sun and poor nutrition.

In addition, women are more likely to suffer from it and it seems that it may also be genetically inherited.

Glaucoma is another condition to watch out for.

The International Glaucoma Association (IGA) says that around two per cent of people over 40 suffer from it in some form and that children and younger people can get it, though it is more likely to occur in older people.

In addition, the IGA explains that glaucoma is at least partly responsible for 13 per cent of people who are registered blind in England and Wales as well as being the greatest reason for preventable blindness within the UK.

Early detection can be crucial to identifying it before it becomes too serious.

Having regular eye tests is an important aspect of eye healthcare, regardless of one”s age.

According to the RNIB”s poll of 5,000 people over 60, 47 per cent were not having their eyes tested every year. This increases the risks of their developing age-related eye conditions without realising it until it is too late.

Barbara McLaughlan, author of the report, urged people not to wait for symptoms to appear before they go for tests and stated: “Age is the highest risk factor in developing some of the most common eye conditions (AMD, glaucoma and cataracts) that can lead to blindness.

“By the time we”re 60, one in 12 of us will have developed a sight problem, by the time we are 75 it is as many as one in six.”

Blind man sees light with bionic eye!

Blind man sees light with bionic eye!

A bionic eye is giving a sightless man glimpses of light, it has been reported.

The man, identified only as Ron, went blind 30 years ago due to retinitis pigmentosa, which damaged his retinas.

But after undergoing surgery at Moorfield”s eye hospital in London, Ron says he is beginning to see light.

He told the BBC he could differentiate between white, black and grey socks and declared: “Suddenly to be able to see light again is truly wonderful.”

His bionic eye, the creation of American firm Second Sight, uses sunglasses with a camera and video processor.

Images are passed to a receiver which subsequently moves them to electrodes on his retina, which can then make use of his optic nerve.

Lyndon da Cruz, who performed the surgery, told the BBC that more testing is needed but said he was “very encouraged”.

Can Contact Lenses Fall Out Your Eye?

 

Can Contact Lenses fall out of your eyes?

 

With normal use, contact lenses will stay firmly in position. Soft contact lenses are particularly stable, and are unlikely to dislodge, even doing active sports.

 

However, they can come out under certain conditions. High winds can cause the eyes to water and cause the lens to move more, increasing the chance of lens loss. A sharp blow to the head may dislodge rigid gas permeable lenses. And rubbing your eye carelessly may result in a lost lens.

 

Describe to your eye care practitioner all of the circumstances in which you are likely to wear your contact lenses. This will help him or her prescribe a type of lens that is less likely to be dislodged given your activities.

Another Win For Science And Eyesight

Another Win For Science And Eyesight

People who have suffered damage to their eyesight due to exposure to bright lights may be able to have their vision restored using infrared light.

Research carried out in Australia on rats found that eye damage was reduced with exposure to infrared light.

But clinical trials will be needed to find out whether the treatment would also work on humans, ScienceAlert reported.

Dr Krisztina Valter of the ARC Centre of Excellence in Vision Science (ACEVS) and the Australian National University said that such damage could be caused to anyone who lives in areas with bright light or whose work exposes them to it.

The theory, explained by Dr Valter, is that infrared prompts more activity from enzymes in cells which enable the production of more energy.

As a result, oxygen stress caused by overexposure to bright light can be countered.

The ACEVS co-ordinates research going on in several Australian universities.

These are the universities of Sydney, Queensland and Western Australia, as well as the Australian National University.
