Optometrist and Director of Flexzoom Optometrist( MEDINI) Sdn Bhd Edmund Chong explained how multifocal contact lenses can alleviate symptoms of digital eye strain( DES), a growing concern among users of digital devices.

MULTIFOCAL LENSES FOR DES

DES manifests as discomfort, blurred vision, and fatigue, often triggered by prolonged screen exposure.

According to Chong:“ Multifocal contact lenses are primarily designed to help people with presbyopia, which typically occurs around the age of 40 when the eye loses the ability to focus on close objects.”

He elaborates that these lenses not only assist those with presbyopia but also offer significant relief for individuals suffering from DES.

The innovative design of multifocal lenses features different zones tailored for various focal distances.

“ For the near zone, they provide a clear focus on close work, such as reading or using smartphones, while the distance zones aid in focusing on dynamic vision.”

This balanced vision experience allows wearers to shift their focus between screens and distant objects with ease, reducing the strain associated with constant refocusing.

RISING TRENDS AND DEMAND

Chong observed a noticeable increase in younger patients seeking multifocal lenses, a trend driven by the rise in screen usage.

“ Even now, schools are using devices to teach kids.”

This shift towards digital learning has led to symptoms of DES appearing in younger demographics, prompting a demand for effective solutions.

“ I prescribe multifocal contact lenses to my patients as young as 35,” he shared, highlighting the need for proactive measures to combat early onset digital eye strain.

Manufacturers are responding to this demand with innovative materials and designs. Lenses with advanced moisture

Edmund Chong retention properties or anti-reflective coatings that reduce glare are becoming increasingly popular.

Additionally, features such as blue light filtering are incorporated to protect against the harmful effects of prolonged screen exposure.

“ As awareness about DES grows, more people are exploring solutions with their eye care practitioners,” he added.

EYE CARE PROFESSIONALS’ ROLE

Chong emphasised the importance of eye care practitioners( ECPs) discussing multifocal options with patients experiencing DES.

“ This demonstrates a proactive approach, offering personalised care that can significantly improve quality of life.”

By addressing both DES symptoms and potential presbyopia, optometrists can enhance patients’ visual comfort and long-term eye health.

He further elaborated on the specific benefits of multifocal lenses for screen users. The smooth transition between focal points reduces eye strain when switching tasks. This feature proves invaluable for individuals who frequently alternate between looking at screens and reading documents.

RECOMMENDATIONS FOR OPTIMAL USE

Chong offered several recommendations for those considering multifocal contact lenses.

“ Choosing the right type of multifocal lenses that suits you is crucial,” he advised, noting that finding the optimal fit may require some trial and error.

Regular follow-ups with ECPs are essential to ensure ongoing comfort and effectiveness.“ I recommend annual eye examinations to maintain good vision.”

In addition, Chong highlighted the importance of using high-quality, breathable lens materials that provide hydration and UV protection- features vital for those who spend extended hours in front of screens.

He cautioned against using incompatible lubricating eye drops, which can lead to discomfort.

“ Patients often find relief by switching to daily replacement lenses, which can be more hygienic and reduce irritation,” he added.

LOOKING AHEAD

Events like the Johnson & Johnson Institute Symposium( JJS) play a crucial role in raising awareness about digital eye strain. Chong believes such gatherings can drive the industry towards a more holistic and patient-centred approach to managing DES.

“ By emphasising the significance of digital eye health, the symposium encourages the adoption of innovative solutions.”

He expressed particular interest in discussions around DES in children and teenagers, a demographic increasingly affected by excessive screen time.

“ Helping this population manage these issues will be beneficial,” he said, reflecting on the concerning rise of myopia among younger users.

As digital devices continue to shape our lives, the importance of addressing DES grows. Multifocal contact lenses represent a promising solution, allowing users to navigate their digital environments with comfort and clarity.

As awareness increases and technology advances, a proactive approach to eye care will be essential in safeguarding our vision in the digital age. – The HEALTH
