Research summary
The increased use of digital devices such as computers, smartphones, tablets has transformed how people learn, work and increasing the use of screens. This creates visual challenges for some users, such as maintaining clear vision for a long period even when looking at different devices. Consequently, digital device users can experience eye problems such as blurred vision, eye strain, headaches, and dry eyes. Such problems are more common in people aged 21-45, and it seems that the COVID-19 pandemic has worsened them. Studies suggest that using specially spectacle designed lenses could reduce these problems. Therefore, we aim to study whether these special lenses are more effective than standard ones in minimising the problems. The study will be conducted at the University of Central Lancashire at the Preston campus (UK). We will recruit 300 patients divided into two equal groups. Patients in group A will receive spectacles with special lenses while group B will receive spectacles with standard lenses. These two groups of patients will be assessed three times, at 4-week intervals, and the final analysis will be performed at 14 weeks. The reduction of the eye problems will be assessed using a validated questionnaire which will produce a score that will be compared between the two groups. The study will start in June and end in September.
The study’s potential benefits are twofold:
1) Patients using the new lenses will hopefully see a reduction in eye problems
2) Opticians will provide be able to provide better patient care.
Carl Zeiss Vision International GmbH c/o (Carl Zeiss Vision UK Ltd) has funded the study. In addition to free eye examinations and spectacles, participants will receive £60 Amazon vouchers at the end of the study as compensation for their time and costs incurred to participate in the study.REC name
