Contact lenses and dry eyes is a common problem leading to failure with contacts.
Success with traditional contact lenses is influenced by various factors: these include environment, occupation, hormones, lens choice, wearer demands, dry eyes and regime compliance plus the experience of the eye care practitioner.
Many comfort issues are related to how the lens and tears interact and complement each other. The lens of first choice for the last twenty five years has been a soft lens which to a greater, or lesser, extent tends to dry out on the eye. Great effort has gone in to producing a lens that doesn’t dehydrate and much has improved but the best lens is still no lens. A contradiction as ‘how do you see with no lens?’.
The answer is to wear it at night and take out in the morning. Now that may seem illogical but Ortho K lenses do exactly that – they are put in before bed and worn overnight. Precious lubricating tears are retained by the eyelids when closed, cushion the lenses as they gently, and minutely, alter and correct the front surface of the eye. This correction lasts all through the following day (sometimes longer!) allowing freedom from the irritation and dryness. Wearers also report little variation in day time vision which can be frustrating to about 20% of day lens wearers.
Ortho K lenses are made from special gas permeable materials that are not affected by the eye being dry. These same special materials have recently been used to bring relieve to severe dry eye sufferers who have needed specialist hospital attention, after normal contact lens wear.
Ortho K lenses are not affected by the hormonal, allergic, environmental or work issues of normal lenses. They are also a great option for sport as you can’t lose them.
