The decisions that we make regarding our eyesight are important, so we all ought to be making them based on the right information! Optical Revolution has conjured up a selection of commonly believed myths associated with sight, and we’re demystifying each take with their accompanying truth.

Sitting too close to the TV or reading in dim light or damages your eyes

We may cause a stir with our first instalment, but sitting too close to the TV isn’t actually proven to have any significant, long-term impact on vision quality – in exactly the same vein as reading in dim light.

From a logical perspective, it does seem to add up. Screens can make our eyes feel strained, achy, and tired, and we often fixate on them for a lot longer than intended at work – or, we warn our kids of the ‘square eyes’ that they’ll wake up with one day if they don’t ditch their devices after school! When it comes to getting through a few chapters before bed by lamplight, we may feel as though our eyes are squinting and labouring to trace the words on the page. Both of the scenarios we’ve described can cause temporary pain, but neither has been shown to have any lasting consequences.

From our point of view, this myth should be kept alive for the sake of acting as a deterrent. Putting our eyes under this kind of strain regularly isn’t advisable, and it can cause a range of other problems such as frequent headaches which can be linked to vision issues. Read or work in well-lit environments, avoid excessive or close-up screen exposure, and take regular breaks to reduce the impact of eye strain.

Myth #2: Eating carrots improves your vision

Carrots won’t improve your vision, but the belief that this one stems from is rooted in science!

The association here comes from the fact that carrots are rich in beta-carotene, a precursor to vitamin A, which is crucial for eye health. However, consuming an excessive amount of carrots in your day-to-day diet won’t magically transform your vision or bring your prescription down by a few digits. A well-balanced diet that includes plenty of antioxidants and nutrients, such as vitamins C and E, zinc, and omega-3 fatty acids, is essential for maintaining good eye health. This positive lifestyle change is also linked to managing the symptoms of AMD, a common age-related sight condition.

Myth #3: Wearing glasses weakens your eyes

Here at Optical Revolution, we’ve got first-hand experience of explaining this one. While we treat our prescription glasses as a visual aid, wearing them doesn’t mean your eyes become weaker or wholly reliant on the lenses. Glasses are corrective, and they’re designed to improve the way we see, promoting clear vision. Going without glasses when you really ought to be wearing them for your daily activities is actually where issues can arise.

Get familiar with your individual prescription by booking an eye test, where one of our expert opticians will be able to explain this one in more detail!

Myth 4: Eye health only matters as you age

Many people perceive vision deterioration as an inevitable aspect of getting older. While it’s true that we can become more susceptible to certain sight conditions as we age, complete eyesight loss is not an inevitable part of getting older – and in our opinion, this should serve as motivation to start taking care of your sight at any age!

Maintaining good eye health is a lifelong commitment, and we’ve made this form of self-care more appealing by curating our own impressive range of stylish, designer prescription glasses. We’ve also created our eyewear styling consultation to give you even more out of your frames, ensuring that they match your lifestyle and enhance your vision perfectly. Other choices such as wearing protective UV sunglasses, eating a balanced diet, and committing to regular eye tests are all decisions that can impact vision quality at any age.

We are advocates for making eyesight a priority across all generations, and we’re eager to play a role in shifting attitudes by debunking this myth in particular.

Myth 5: Eye exercises can eliminate the need for glasses

While eye exercises can help alleviate eye strain and improve focus, they cannot correct refractive errors like nearsightedness or farsightedness. If you need glasses and don’t already have a pair with the right prescription, eye exercises alone won’t eliminate the need for corrective lenses either.

These movements might alleviate the effects of a long day sitting at a laptop, or they could even help your eyes to adjust to a new pair of frames – but their benefit doesn’t stretch beyond this point.
