Covid-19 is continuously sprouting its tentacles in the form of new variants. With genetic instability in virus genomics and structure, Variants of Concern have emerged thick and fast from the original virus. Omicron is the latest of the variants which has emerged out to be the new concern to the health, economics and world order. With 34 mutations in spike protein and 15 in its receptor binding domain alone, Omicron is really a variant of concern. High number of non-synonymous mutations in spike protein has been revealed in omicron variant that are involved in transmissibility, disease severity and immune escape. A total of more than 60 mutations have been reported in omicron variant making it variant with the most mutations sites of all SARS-Cov-2 variants characterized so far. COVID-19's ability to induce long-term consequences was unknown at the start of the epidemic. However, it has been discovered that this is not the case, and people with "long haul COVID-19" might experience a variety of ocular problems.
