Contact lens overwear is described as a syndrome that develops once the contact lens are used for an extended period. Among those who use contact lenses, the amount of oxygen that the cornea is supplied with is reduced and if worn too long, the cornea starts to develop issues.
In most circumstances, the individual will initially notice the symptoms a few hours after the contact lens were removed or might even wake up from sleep due to intense pain. In one study conducted, contact lens overwear typically occurs among those who use the hard type contact lenses but can still occur among those who use the extended-wear lenses.
When it comes to contact lens overwear, the diminished supply of oxygen to the cornea can lead to edema or corneal swelling. Since the cornea should be transparent and thin for normal and clear vision, the development of edema can cause blurred vision.
Taking a break from contact lenses can help improve the condition, but a change in the wearing habits is also vital to prevent recurrence of the symptoms as well as any long-term consequences.
Can contact lens overwear trigger eye pain?
An individual suffering from contact lens overwear usually has intense eye pain. This is triggered by changes in the epithelium of the cornea that ranges from minor defects known as superficial punctate keratitis or corneal abrasion.
If not promptly and properly managed, the changes in the cornea can progress into a corneal infection or ulceration. In case an abrasion is present, the doctor will prescribe antibiotic drops or ointment to treat the complication. During this period, the individual should avoid using contact lenses until the cornea has fully healed.
Sensitivity to light
Being sensitive to light is often linked with contact lens overwear. In most cases, there is inflammation in the anterior chamber of the affected eye. It is important to note that the front chamber is the region flanked by the cornea and the tinted iris. The development of inflammation can lead to light sensitivity.
Depending on the degree of the sensitivity, the doctor might prescribe an eye drop that works by dilating the pupil, relaxing the iris as well as relieving the discomfort upon exposure to light.
