The last method in our vision correction cycle is hard contact lenses for night use. They are second to safety after points. Conventionally, the safest correction method is definitely glasses (with durable polycarbonate lenses), then ReLEx SMILE and hard night lenses, then femtoLASIK and PRK, then soft one-day lenses, then “barbaric methods” — soft lenses of long-wearing and LASIK. Separately, there are phakic intraocular lenses and artificial lenses — they are best done only by direct medical indications (quite an invasive method for refractive indications).
The main advantage of night lenses is clinically proven to stop progressive myopia. Therefore, they are often prescribed to children when the eye is actively developing. After 20 years, this effect decreases by an order of magnitude, but a couple of other advantages remain.
Payback for the obvious advantages — the high price of such lenses, the need for strict discipline and regular sleep for at least 7 hours.
