Contact lenses: the silent damage to your cornea after decades
What happens when you've been wearing contact lenses for more than 20 years? Testimonials from veteran users paint an uncomfortable picture: chronic dry eye, visible veins in the sclera and a growing intolerance that forces them to cut back on wearing time or give lenses up altogether. Some point to corneal neovascularization as a real risk if the abnormal vessels reach the cornea.
The material change: lower quality or greater sensitivity?
Several users who wore Acuvue Oasys for years claim the manufacturer changed the composition, and that the lenses now cause allergies and deteriorate after 15 uses. Although there is no official confirmation, suspicion is spreading among those who noticed that today's lenses are no longer what they used to be. Opticians' usual response is to sell a different brand, but that doesn't always solve the underlying problem.
Cleaning routines: hydrogen peroxide vs. multipurpose solution
The battle of the solutions has two camps. On one side, those who defend multipurpose solutions (like Renu, from Bausch & Lomb) and warn of the danger of poorly neutralized hydrogen peroxide. On the other, the nostalgics of the two-step system (cleaner + neutralizer), who consider it more effective. What nobody disputes: putting contact lenses in tap water is reckless.
Alternatives for sports: beyond glasses
For those who exercise, contact lenses remain a nuisance. Some choose to wear nothing at all; others turn to pinhole glasses, which give a few hours of sharp vision after taking them off. A low-tech solution that baffles those used to medical technology.
The final advice: get surgery or resign yourself
After decades of use, the outcome for many is refractive surgery. In the meantime, limiting wearing time to six hours a day, resting on weekends and using lubricating drops are commonly shared guidelines. That, and crossing your fingers that neovascularization doesn't get complicated. Irony of pogre: what freed us from glasses may end up requiring a scalpel.
