Can I become an air hostess if I wear specs or lenses?

I have written an elaborated article on eyesight for aviation professionals. You must go through that to address your issues related to eyesight and the levels of acceptability for the same. https://www.shiksha.com/aviation/articles/can-your-eyesight-issues-dampen-the-chances-of-becoming-a-pilot-blo

As per the criteria, you should have 6/6 uncorrected vision in each eye, but no specs. You can wear lenses but see to it that lenses should be genuine because lenses are also hurt the eyesight, so select good lenses and fly high with your dreams. All the best.
