Debunking Myths About Vision

In a world where misinformation's rampant, eye health professionals have joined forces to debunk myths and shed light on the truth about our vision.

"Having 20/20 vision means your eyesight is perfect."

Many individuals mistakenly believe that having 20/20 vision equates to flawless eyesight. However, this is not entirely accurate. While 20/20 vision is considered normal it only indicates how well you can read an eye chart from a distance. Vision encompasses more than this measurement; other factors such as color vision, peripheral vision and contrast sensitivity also play roles.

"Blue light can harm my eyes."

There has been discussion about the effects of blue light emitted by screens on our eyes. Nevertheless, research has revealed that our eyes possess defenses against light and that it does not pose a threat to eye health. The impact of light is closely linked to sleep patterns so wearing glasses with blue light filters can help alleviate discomfort when using screens for periods.

"Losing your vision is a consequence of aging."

It's a misconception that aging invariably leads to loss of vision. While certain changes associated with aging, like presbyopia (difficulty focusing on objects) may occur, many older individuals maintain eyesight throughout their lives.

Regular eye examinations can play a role in detecting and addressing age related eye issues.

"While LASIK can provide vision it doesn't guarantee eyesight for life. Some individuals may still require glasses for tasks. May experience a gradual decline in their vision over time. LASIK helps with errors. It can't prevent the natural changes that occur as we age."

"Color blindness doesn't mean seeing everything in black and white. People with color blindness have difficulty distinguishing between colors, reds and greens. This condition affects around 8% of the population, generally doesn't have an impact on everyday life."

"Engaging in eye exercises does not change the structure of your eyes or correct vision problems such as near-sightedness or astigmatism. While some exercises might help alleviate eye strain, they cannot rectify errors. Seeking eye care remains the recommended approach to improving your vision."

"Wearing glasses won't worsen your vision; instead, they help correct it. They do not affect the progression of conditions, like myopia. However, neglecting to wear glasses, when necessary, can strain your eyes. Having dry eyes may seem like an issue but it’s essential not to underestimate their impact. If left untreated dryness can lead to discomfort, damage to the cornea and even eye infections. It's important to use lubricating eye drops and follow your eye doctors’ recommendations."

"The idea that sneezing with your eyes open can make them pop out is a myth. Our eyes are securely held in place by a network of muscles and tissues so there's no risk of them dislodging when you sneeze."

"There is no chance for contact lenses to get lost behind your eye. The conjunctiva acts as a barrier that prevents objects from moving behind the eye. If you feel like a contact lens has shifted, simply blinking or using tears should help it reappear."

"Sunglasses play a role in safeguarding our eyes from UV rays and are highly recommended. Prolonged exposure to sunlight without eye protection can lead to eye problems such as cataracts and eye cancers. It's important to choose sunglasses that offer 100% UVA and UVB protection, for safety."

While floaters are generally common and harmless it is true that they should not be dismissed completely.

However, if you suddenly notice an increase in floaters it could be a sign of a tear or detachment which requires attention from an eye specialist.

Contrary to belief eye color inheritance is not solely determined by the eye color of two parents. Eye color is influenced by factors that don't strictly adhere to a pattern. Although less common it is indeed possible for two parents with eye colors to have a child with eyes.

To maintain vision throughout your life it's important to understand the truth behind these eye related myths. Regular check-ups with an eye specialist protecting your eyes from sunlight and making decisions about your eye care can significantly contribute to lasting eye health.
