Influence of Face Masks on the Use of Contact Lenses

Vision Correction Habits After COVID-19 Onset in Spectacle and Contact Lens Wearers

PURPOSE

To determine how vision correction habits changed after the 2019 coronavirus disease (COVID-19) pandemic onset.

METHODS

Participants reported vision correction habits, refractive error, screen time, mask wearing time, and dry eye symptoms since the COVID-19 pandemic onset through email survey.

RESULTS

A total of 133 participants completed the survey. Worsening dry eye symptoms were associated with increased screen time ( P =0.04). Hours per day of spectacle wear increased by approximately 1 hr ( P =0.001) and was associated with increased screen time ( P =0.002). Worsening dry eye symptoms were associated with increased days per week of spectacle wear ( P =0.02). Participants wore contact lenses about one day per week less than before the pandemic ( P =0.0001). Increased mask wearing time was associated with increased days per week of contact lens wear ( P =0.03).

CONCLUSIONS

After pandemic onset, hours per day of spectacle wear increased, and days per week of contact lens wear decreased. Increases in hourly spectacle wear were associated with increased screen time, whereas increased daily contact lens wear was associated with increased mask wear time, suggesting that spectacles may be preferred for screen time activities and contact lenses for mask wear.

Face Mask and Tear Film Stability: A Pilot Study of the Objective Measurement of Tear Break-Up Time

(1) Background: Mask-associated dry eye (MADE) has been associated with increased dry eye symptoms, apparently due to reduced tear break-up time (TBUT). This study aimed to determine the short-term impact of surgical face mask (FM) on tear film stability by measuring non-invasive tear break-up time (NIBUT). (2) Methods: Twenty-six healthy participants had NIBUT evaluated without FM, with surgical FM and with a surgical FM secured to the skin with adhesive tape (TFM). NIBUT-first was measured with Keratograph 5M (K5M, Oculus, Wetzlar, Germany). Each participant had NIBUT measured in four sessions on four consecutive days. Session 1: without FM vs. with FM. Session 2: with FM vs. without FM. Session 3: without FM vs. with TFM. Session 4: with TFM vs. without FM (3). The time between each measured setting was 2 min. Results: The mean ± SD NIBUT without FM was 8.9 ± 3.7, with FM 10.2 ± 4.1, and with TFM 8.4 ± 3.8 s. No significant differences were observed in NIBUT in any of the evaluated settings: without FM vs. with FM (p = 0.247), without FM vs. with TFM (p = 0.915), and with FM vs. with TFM (p = 0.11). (4) Conclusions: This study did not find a significant short-term effect of FM on NIBUT. Other variables or longer periods of exposure might trigger the symptoms and ocular surface alterations in MADE.

Study of Face Mask-associated Dry Eye among Medical Students

Purpose

The purpose of this study was to evaluate face mask-associated factors causing dry eye among medical students.

Methodology

This was a cross-sectional study conducted on undergraduate medical and dental students, of all phases, while they were attending offline classes and were required to wear face masks in accordance with the government regulations. Sociodemographic data, ocular and medical history, face mask-wearing practices, screen usage, and quantification of symptoms using the modified Ocular Surface Disease Index (OSDI) questionnaire were collected. Objective tests were conducted in students having dry eye. The association of quantitative variables was done using ANOVA, Mann-Whitney, and Kruskal-Wallis test, whereas the Chi-square test was done for qualitative variables. Multivariate logistic regression was used to identify the risk factors for varying severity of dry eye.

Results

The mean age of the 410 students was 21 ± 1.6 years. According to the OSDI, 39.51% (162/410) of students had dry eyes, 23.41% (96/410) had mild dry eye, 8.78% (36/410) had moderate dry eye, and 7.32% (30/410) had severe dry eye. Face mask-associated factors which were significantly linked to dry eye were N95 masks, loose-fit masks, and 6-8 h of continuous mask use. The Schirmer's test and tear film break-up time were performed on 29 and 20 students, respectively, mean values being 19.25 ± 5.29 mm and 10.15 ± 1.41 s for nonsevere and 6.53 ± 1.55 mm and 5.3 ± 0.98 s for severe dry eye, respectively.

Conclusion

It is important to educate medical students and create awareness regarding "face mask-appropriate behavior" to reduce the chances of dry eye secondary to face masks use.

TFOS Lifestyle: Impact of contact lenses on the ocular surface

Several lifestyle choices made by contact lens wearers can have adverse consequences on ocular health. These include being non-adherent to contact lens care, sleeping in lenses, ill-advised purchasing options, not seeing an eyecare professional for regular aftercare visits, wearing lenses when feeling unwell, wearing lenses too soon after various forms of ophthalmic surgery, and wearing lenses when engaged in risky behaviors (e.g., when using tobacco, alcohol or recreational drugs). Those with a pre-existing compromised ocular surface may find that contact lens wear exacerbates ocular disease morbidity. Conversely, contact lenses may have various therapeutic benefits. The coronavirus disease-2019 (COVID-19) pandemic impinged upon the lifestyle of contact lens wearers, introducing challenges such as mask-associated dry eye, contact lens discomfort with increased use of digital devices, inadvertent exposure to hand sanitizers, and reduced use of lenses. Wearing contact lenses in challenging environments, such as in the presence of dust and noxious chemicals, or where there is the possibility of ocular trauma (e.g., sport or working with tools) can be problematic, although in some instances lenses can be protective. Contact lenses can be worn for sport, theatre, at high altitude, driving at night, in the military and in space, and special considerations are required when prescribing in such situations to ensure successful outcomes. A systematic review and meta-analysis, incorporated within the review, identified that the influence of lifestyle factors on soft contact lens dropout remains poorly understood, and is an area in need of further research. Overall, this report investigated lifestyle-related choices made by clinicians and contact lens wearers and discovered that when appropriate lifestyle choices are made, contact lens wear can enhance the quality of life of wearers.

TFOS lifestyle: Impact of societal challenges on the ocular surface

Societal factors associated with ocular surface diseases were mapped using a framework to characterize the relationship between the individual, their health and environment. The impact of the COVID-19 pandemic and mitigating factors on ocular surface diseases were considered in a systematic review. Age and sex effects were generally well-characterized for inflammatory, infectious, autoimmune and trauma-related conditions. Sex and gender, through biological, socio-economic, and cultural factors impact the prevalence and severity of disease, access to, and use of, care. Genetic factors, race, smoking and co-morbidities are generally well characterized, with interdependencies with geographical, employment and socioeconomic factors. Living and working conditions include employment, education, water and sanitation, poverty and socioeconomic class. Employment type and hobbies are associated with eye trauma and burns. Regional, global socio-economic, cultural and environmental conditions, include remoteness, geography, seasonality, availability of and access to services. Violence associated with war, acid attacks and domestic violence are associated with traumatic injuries. The impacts of conflict, pandemic and climate are exacerbated by decreased food security, access to health services and workers. Digital technology can impact diseases through physical and mental health effects and access to health information and services. The COVID-19 pandemic and related mitigating strategies are mostly associated with an increased risk of developing new or worsening existing ocular surface diseases. Societal factors impact the type and severity of ocular surface diseases, although there is considerable interdependence between factors. The overlay of the digital environment, natural disasters, conflict and the pandemic have modified access to services in some regions.

The effect of COVID-19 pandemic and wearing face masks on ophthalmology practice: What is known so far? A narrative review

Face masks, along with other preventive measures, can help slow the spread of COVID-19. Despite the positive effect of the mask in combating the virus, it has some negative effects on the human body that must be followed up on and reduced. In this study, we discuss the impact of wearing face masks on the eye and the common issues associated with using them. The literature search was conducted using electronic databases such as PubMed and Google Scholar. Only articles published in English were included. A total of 39 relevant articles were deemed eligible. After the duplicate articles were removed, the titles and abstracts of 20 papers underwent full-text screening. The review comprised both prospective and retrospective investigations, case reports, and a series of reporting ocular symptoms following the use of face masks. The COVID-19 pandemic affected ophthalmology practices in managing patients. New factors must be considered, especially when dealing with anti-VEGF injections, such as the risk of endophthalmitis, tests and symptoms of patients with glaucoma, and the emerging symptoms associated with the COVID-19 vaccination. The use of face masks and breathing aids seemed to influence the tear film.

The impact of covid-19 on soft contact lens wear in established european and us markets

Purpose

To characterise changes in soft contact lens wearing habits during the COVID-19 pandemic.

Methods

A detailed online questionnaire was circulated to individuals aged 40–70 years, during the period April to May 2021. Data sampling took place in the United Kingdom (UK), United States of America (USA), Netherlands, Germany, France, Spain and Italy. Only data pertaining to individuals who were soft contact lens wearers were included. Data were extracted for questions relating to contact lens wearing habits pre- and during the COVID-19 pandemic, and expectations for future lens wear beyond the pandemic.

Results

Seven-hundred and twenty-eight individuals were identified as soft contact lens wearers of which six-hundred and nineteen wore a combination of contact lenses and spectacles. Most respondents indicated contact lens wear times had either remained the same (57.3%) or increased (9.8%) during the pandemic. The country with the greatest proportion of respondents decreasing wear time during COVID-19 was the UK (45.3%), and the least in the Netherlands (20.0%). The primary cause of decreased lens wear was attributed to leaving the home less often (70.0%), and the second most common reason due to concerns about hygiene (10.8%). Most respondents (83.9%), however, expressed a desire to return to pre-pandemic wear times once the pandemic was over.

Conclusions

Practitioner concerns about contact lens market recovery ought to be assuaged by the survey outcomes which show most individuals to have maintained lens wear during the pandemic. In view of the continued lens wear, as and when restrictions ease, ECPs may wish to encourage patients to return for routine check-ups that may have been missed due to the pandemic.
