KUALA LUMPUR: Once seen as an alternative for those who prefer not to wear glasses, contact lenses – including non-prescription ones – have become a popular choice, especially among women.
In their pursuit of enhanced appearance, however, many users risk their eye health by ignoring proper contact-lens guidelines, which could potentially lead to blindness.
Nur Farah Wahida Mohd Azizan said she once experienced itchiness, irritation and redness in her eyes, prompting her to seek medical advice.
“Last year, my eyes would get red very easily even when I wasn’t wearing contact lenses. I went to see a doctor, who said it was likely due to frequent contact-lens use, which my eyes could not tolerate anymore,” the 26-year-old recalled.
She has now returned to wearing glasses, and limits her lens usage to five times a month.
According to optometrist Muhammad Adam Zakaria, Nur Farah Wahida’s experience is not uncommon, especially among users who do not fully understand the type of contact lenses they are using or the recommended replacement schedule.
He once treated a patient in her 20s who suffered from a corneal ulcer, which led to impaired vision almost to the brink of blindness.
“When she came in, her eyes were already in a severe condition to the point that she had difficulty opening them,” he shared, adding that the ulcer left a permanent scar on her cornea.
Adam stressed that wearers must be aware of the type of lenses they use, including whether they are meant to be replaced daily, monthly or annually.
He noted that hygiene issues are more commonly associated with those intended for longer-term use, such as monthly or yearly lenses, which require proper cleaning methods including the use of multipurpose solution.
Wearers should be aware of proper cleaning and storage methods, as well as how frequently the lenses need to be replaced. (Envato Elements pic)
In addition, the type of lens material plays a significant role, with hydrogel lenses suitable for up to eight hours of wear, and silicone hydrogel lenses for up to 12 hours.
“Hydrogel lenses usually have a higher water content to make them softer, but they also absorb more of our natural tears to maintain moisture.
“This differs from silicone hydrogel lenses, which do not absorb as much water due to their more advanced technology,” said Adam, who has seven years of experience in the field.
He further cautioned that wearing contact lenses for too long can reduce oxygen absorption into the eyes, leading to dryness and allergic reactions.
Having previously served at a specialist eye hospital, Adam advises users to first consult an optometrist to learn about proper handling and care, as well as to obtain the correct lens power and optimal measurements.
Users are also urged to purchase contact lenses only from registered sellers to ensure safety and hygiene.
