Do have a sandy gritty feeling in your eyes? If you frequently wear contact lenses, you may be familiar with this condition. Some blame it on things in the environment such as wind, smoke or dry heat but this is not always the case.
Eyes Dry From Soft Contacts
Soft contact lenses are made of plastics that contain water, depending on the intended wearing schedule; lenses can contain 30-75% water. Overtime this moisture evaporates and it then absorbs water from your own tears. Eventually eyes can become dry, red, even blurry vision can occur.
For many dry eye symptoms are a short-term issue. However, for those who have worn contacts for many years dryness can come from damage to hairlike structures on the cornea causing poor tear film stability.
Dryness From Rigid Contact Lenses
If you wear rigid gas permeable lenses, they are more prone to dryness despite the efforts of manufactures to make them more compatible with natural tear film. This kind of contact lens contains no water in the lens vs. soft lenses. By nature, its polymeric hydrophobic materials repel tears/moisture present in the eye.
