Glasses wearers quickly noticed that wearing the mask for two years quickly fogged up the lenses. This condensation comes from the patient’s own breathing when wearing a mask. At a time in our history when health authorities were asking us not to touch our faces, this fog made many uncomfortable. Even though the mask requirement has been relaxed or even removed in most countries, many people still plan to wear masks indoors or in large crowds, and some even anticipate vaccine-resistant strains. Given that masks will most likely be in use for some time to come, the Lasik surgery is for many a very effective and safe way of eliminating the problem of foggy glasses.
