I recommend Friends Eye Drops.

When my eyes are dry or gritty, I look for artificial tears.

The eye drops I recommended are Friends Eye Drops.

If you want a gentle moist sensation, choose Friends Eye Drop Soft; if you prefer a refreshing coolness, choose Friends Eye Drop Cool; and if you desire a strong cool sensation, opt for Friends Eye Drop Cool High.

These days, since many people wear contact lenses and undergo LASIK or LASEK surgeries, it seems that they use artificial tears quite frequently.

There are also disposable products available, so you can use them comfortably.

It also contains glucose and is preservative-free, so I think it's good.
