Eye discomfort at the end of the day is almost always caused by a chemical issue called Delayed subjective dryness (DSD). It is a common soft contact lens complication that has consistent and specific characteristics. Generally, it is progressive in nature and causes reduced wearing time and then contacts failure.
People who experience DSD often think that it normal consequence of wearing contact lens, due to which it goes unreported at its early and moderate stages. Eventually, they simply give up wearing contact lenses as glasses feel more convenient.
Characteristics of Delayed Subjective Dryness
There are several characteristics of delayed subjective dryness that might help you recognize the complication. Firstly, lenses start to feel dry once the initial period of good comfort passes. Secondly, it gets gradually worse with time. Thirdly, lubricating drops provide relief a brief period. Fourthly, patients feel like they want to rip the lenses out.
People who have DSD will feel dryness after only a few hours of wearing whereas people with no eye complication can wear lens up to 12 hours without feeling any kind of discomfort.
A lens that fits perfectly well will be comfortable between the wearing time and the onset of DSD.
Another complication that can cause irritation is dry eye. It is milder than DSD but still, it can be very discomforting. The dry eye responds well to lubricating drops and they provide substantial relief.
A patient can both DSD and dry eye at the same time but they are two unrelated clinical entities.
Other factors that can cause discomfort are; poor fit, environmental Allergens or some underlying condition like an infection.
