text: how do i reverse redness in both eyes from eye drop over use, caused by years of using naphcon a eye drops.? please help me if you know the answer to this, my optomotrist says its allergies, but i didnt mention the eye drop over use...and its staring to affect my self esteem . i wonder if there is an underlying cause that isn't the naphcon, don't feel embarassed telling your optometrist that you overuse the naphcon, they can only help and as you say it is affecting your self esteem so i think you would feel enormously relieved if you did go and get it checked out.
