Sponsor's own description

The increased use of digital devices such as computers, smart-phones, tablets, and laptops has transformed how people learn and work and has increased the use of screens. This has created visual challenges for some users, such as maintaining a 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 designed lenses could reduce these problems. Therefore, the investigators aim to study whether specially designed lenses are more effective than standard ones in minimising these problems. The study will be conducted at the University of Central Lancashire at the Preston campus (UK). The study will recruit 300 participants, divided into two equal groups. Participants in group A will receive spectacles with special lenses while group B will receive spectacles with standard lenses. All Participants 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 at the end of the study.

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.
