(Eye drops) I recommend Friends Eye Drops.

Recently, due to prolonged use of smartphones, my eyes become dry and gritty, leading me to use artificial tears.

Friends Eye Drops provide a cooling sensation using menthol; the blue version offers a refreshing feeling, while the pink does not. They contain sodium chloride and potassium chloride, which are similar to tears, and also contain glucose to supply nutrients to the corneal cells that make up the eye. The advantages include being usable even while wearing contact lenses and being easily available at pharmacies without a prescription.
