Cheap Spectacles could STRAIN the eyes & make you dizzy...

Hidden health risk in reading glasses: Cheap spectacles can strain the eyes and make you feel dizzy

  • Glasses from high street chains have faults which can damage the eyes
  • Extreme side effects include double vision, a new study warns
  • Consumer group Which? tested 18 models from high street stores
  • Expensive £27.50 pair from Boots were no better than a £4 pair

Picking up a pair of reading glasses on the high street probably seems like a far-sighted budget solution.

But while they’re relatively cheap, ready-made glasses may come with a hidden health risk.

They can potentially cause eye strain, dizziness and even double vision, according to an expert study.

Consumer champions at Which? asked an optometrist to assess 18 pairs of ready-made reading glasses bought from high street chains.


The magnification was correct across all the samples. But he noted other faults in eight pairs of glasses, including some from Boots and Superdrug.

And the faults were not confined to the cheapest. The most expensive pair cost £27.50 from Boots – but they were no better than a £4 pair from a chain called Tiger.
 


The worst example was sold under the Clarifeye brand at Poundstretcher for £2.99.

Which? said: ‘These had three main faults. The lenses were not centred correctly, they were distorted and loose in the frame.’

A Foster Grant pair which cost £18.50 at Superdrug were also incorrectly centred, as were a £27.50 pair described as Style H by Boots.

A spokesman for Which? said: ‘Buying ready-made reading glasses may be easy on your wallet, but our snapshot investigation shows that some could put your eyes under too much strain.


‘The faults we found could cause symptoms in the wearer, from headaches to eye strain, slight dizziness and even double vision.’


The consumer group said the research findings make it difficult to recommend a particular brand or retailer.


Rather, it said buyers should look out for glasses protected by packaging which show no evidence of dents or scratches.


It said: ‘Make sure the frame is marked with industry standard markings such as CE. Ensure the frame fits comfortably and try them out. You should be able to read easily for two minutes.


‘If you buy them from an optician, ask for the lenses’ power and centre positions to be checked.’


Which? also advised buying pairs which have a spring hinge and to go for plastic frames rather than cheap and thin metal, which can break.

How eating too many sweets could make you FORGETFUL: Having high blood sugar levels can cause memory problems

  • Maintaining low blood sugar levels is good for the brain
  • Study showed people with too much sugar in their blood were less able to recall a list of 15 words 30 minutes after they had heard them
  • Suggests lowering blood sugar levels could be a way of preventing cognitive decline with age

Bad news if you've got a sweet tooth - eating too many sweets could make you forgetful.

Researchers have found that maintaining low sugar levels in the blood is good for the brain.

The study, published in the journal Neurology, showed people with too much sugar in their blood were more likely to have memory problems.

Researchers looked at 141 people with an average age of 63 who did not have diabetes or pre-diabetes.

Those with less sugar in their blood were more likely to score well on memory tests.
The researchers found that people with high levels of sugar in their blood were less able to recall a list of 15 words 30 minutes after hearing them.

An increase of about seven mmol/mol of a long-term marker of glucose control called HbA1c went along with remembering two fewer words.

Dr Agnes Floel, of Charite University Hospital in Berlin, said: ‘These results suggest even for people within the normal range of blood sugar lowering their blood sugar levels could be a promising strategy for preventing memory problems and cognitive decline as they age.


‘Strategies such as lowering calorie intake and increasing physical activity should be tested.’

Volunteers who were overweight, who drank more than three-and-a-half servings of alcohol per day and who had memory and thinking problems were ruled out before the study started.


The participants’ memory skills were then tested along with their blood glucose levels.

Participants also had brain scans to measure the size of their hippocampus.

Dr Clare Walton, research communications manager for the Alzheimer’s Society, said: ‘We already know that type 2 diabetes is a risk factor for developing Alzheimer’s disease, but this new study suggests that higher blood sugar levels may also be linked to poor memory in people without diabetes.


‘The research suggests that regulating blood sugar levels might be a way to improve people’s memory, even if they don’t have diabetes.

‘However, before people without diabetes consider changing their diets or taking medication, more research is needed to test this theory. One in three people over 65 will develop dementia so investing in research like this is vital.’

CHICKEN NUGGET under the MICROSCOPE

See what a chicken nugget looks like under the microscope: Still enjoying that 'super glue' of cartilage, blood vessels and fat?

  • Researchers in Mississippi examined chicken nuggets at two different fast-food chains and found that only about half of the nuggets were made of muscle meat
  • The rest of the nuggets were made of other chicken parts like fat, blood vessels, nerves, bones and cartilage
  • A representative for the National Chicken Council said it's no mystery what's in chicken nuggets since nutritional information is often available online or on the packaging

To the naked eye, a chicken nugget may seem like a relatively healthy and wholesome treat, but under the glare of a microscope the offal truth is revealed. 
 
Dr Richard D. deShazo, a professor of medicine and pediatrics at University of Mississippi Medical Center, said that he was 'floored' and 'astounded' when he took a closer look at the make-up of the ubiquitous all-American meal.

When Dr deShazo and pathologist Steven Bigler sliced into a pair of randomly selected nuggets - bought from two different fast-foot chains - they discovered a jumble of blood vessels, fat, cartilage, but not a whole lot of actual chicken meat.

The offal truth: When researchers placed a pair of chicken nuggets from two fast-food chains under the microscope, they discovered a concoction of blood vessels, fat, intestinal tissue, but little actual meat

A study of the chicken from the first restaurant revealed that it was 50 per cent muscle. The other half of the nugget was made up of fat, blood vessels, nerve and epithelium tissue from birds’ cavities.

The nutritional breakdown was 56 per cent fat, 25 per cent carbs and 19 per cent protein, according to The Atlantic.
The nugget from the second restaurant was 40 per cent skeletal muscle, a mix of fat and connective and organ tissue, as well as bone debris.

Dr DeShazo compared nuggets served in some national franchises to ‘super glue’, comprised of bits of poultry leftovers mashed up with fatty ‘goo’ and fried in salty batter. 
 
The scientist insisted that calling the product 'chicken nuggets' is misleading, because they are mostly fat tissue rather than actual poultry meat.

'What has happened is that some companies have chosen to use an artificial mixture of chicken parts rather than low-fat chicken white meat, batter it up and fry it and still call it chicken,' Dr deShazo said.
'It is really a chicken by-product high in calories, salt, sugar and fat that is a very unhealthy choice. Even worse, it tastes great and kids love it and it is marketed to them.'

The National Chicken Council, a non-profit group that represents America's poultry producers, has dismissed Dr deShazo's finding, arguing that nuggets are 'an excellent source of protein' - especially for children who tend to be finicky eaters.

But according to Dr deShazo and healthy-eating advocate and renowned chef Jamie Oliver, that is part of the problem.

According to Oliver, America’s kids have been 'brainwashed' to such a degree that even if they know that nuggets are mostly made of goo and bone bits, they would still happily eat them.


The problem is especially acute in Dr deShazo's home state of Mississippi, which has the highest rate of childhood obesity in the country.

Don't make it a habit: Dr deShazo, the lead researcher of the study, said it's OK to eat chicken nuggets every once in a while but he's concerned for the people who eat them multiple times a week

By 2030, Mississippi is projected to have the highest obesity rate at 66.7 per cent.
Ashley Peterson, a representative of the NCC, pointed out that nutritional information for most fast food chains is available online, and that anything for sale at the grocery store has a list of ingredients.

'Chicken nuggets tend to have an elevated fat content because they are breaded and fried. But it's no secret what is in a chicken nugget,' she said.
To counter claims similar to the ones laid out in D deSahzo's study, KFC and Chick-fil-A have been running ads touting their chicken nuggets as made entirely of breast meat.
