Brief Summary

The study is conducted to evaluate the efficacy of digital blue light blocking filter in improvement of clinical indices of dry eye and ocular symptoms related to dry eye. Introduction: Dry eye disease is a multifactorial disease of the ocular surface caused by loss of tear film homeostasis resulting damage to the ocular surface and neurosensory abnormalities.

Conditions

Dry Eye Disease

Outcome Measures

Primary Outcomes (3)

• tear break up time

  improvement in evaporative dry eye will be assessed by improvement in tear break up time in seconds after filter use.

  8 weeks

• Schirmer test values

  improvement in aqueous deficient dry eye by Schirmer test values in mm .

  8 weeks

• corneal surface staining

  'corneal surface staining grade scale' assess the improvement corneal surface erosions after filter use

  8 weeks

Secondary Outcomes (1)

• ocular surface disease index questionnaire

  8 weeks

Study Arms (2)

1 blue light blocking filter group

EXPERIMENTAL

digital blue light blocking filter is installed laptops and mobile phones of 80 individual using digital devices more than 4 hours. asked them to use the filter continuously while using digital devices.

Device: Digital blue light blocking filter

2 non filter users

EXPERIMENTAL

Effect of time duration of digital screen on the dry eyes is checked.

Device: Digital blue light blocking filter

Interventions

Digital blue light blocking filter DEVICE

digital blue light blocking filter will be given to 80 dry eye subjects in mobile phones and laptops and 80 individuals will be without filters digital devices users

Also known as: F.lux and blue light filter Night mode,Night shift

1 blue light blocking filter group; 2 non filter users
