Allergy To Eyeglass Cleaner
Hurts the eye: Actually, the benzalkonium chloride preservative can damage the cornea. This is not usually a concern because the bac gets washed out of the eye before it can cause any harm, but if you use the drops with contacts, the contact lenses hold the preservative onto the cornea for long enough to cause damage. ...Read moreSee 1 more doctor answer
Allergies occur when your immune system is triggered by envirionmental factors it should ignore--for example, pollen in the air, or dander on a cat or dog--and creates cells to fight against them. An allergic reaction typically causes itching, congestion, or drainage, and ...Read more
Skin and contacts: There should be absolutely no issue between allergy to make-up and contacts. ...Read more
Not really: You can rewet a hard lens and reuse it after cleaning. A soft lens, when dry, has a collapse of the matrix of the plastic and is completely useless after it dries out. So drops cannot rehabilitate such a lens. ...Read more
Not exactly: While there are certainly worse things to put in your eyes, the multipurpose contact lens solution is not chemically designed to use as a lubricant for the eyes. The pH and overall chemical composition was designed for the disinfecting of contact lenses; while in very small quantities, it won't harm the eyes, to use them regularly and in larger quantities will irritate the eyes significantly. ...Read moreSee 1 more doctor answer
Visine allergy: There are several visine preparations containing different drugs, but most contain a topical decongestant (tetrahydrozoline) and preservative (benzalkonium chloride). True allergic reactions to either are rare, but the preservative can be irritating if you have a condition such as eczema. More likely, the topical decongestant can cause a rebound reaction with increased redness from overuse. ...Read more
Yes: Topical antihistamine agents are generally very effective for treatment of seasonal allergy eye conditions. However, as the season progresses, they often lose their effect. That does not make this "bad" medicine; rather, it probably attests to the severity of allergies that you have. ...Read more

Eyeglass coating: Coatings can include anti glare coating, anti scratch coating or coating for uv light. Best care involves using a special cloth for optical plastic and eyeglass cleaner. ...Read more
Usually yes: If the frame is not damaged and has a contemporary design, then usually lenses would be able to be cut by the optician to fit the frames. There are some older frames where it can be very difficult to fit lenses. ...Read more
How to wash prescription eyewear lenses? Is using water and dish soap bad for lenses with blue light block coating? and how to dry them?
Soap and water ok: Soap and water are ok but many prefer a hypercloth available on line in most stores. These pick up oils and do not scratch, and they dry as they clean. ...Read more
Not correct: Eyeglasses and contacts lens prescriptions are not the same. There is a power difference since the glasses are farther from the cornea surface compared to contact lens. Thus you need a different prescription, plus contact lens requires a base curve and diameter in addition to the power. ...Read moreSee 1 more doctor answer
Which is a better product for routine contact lens moisturizing? Blink Contacts or Visine for Contacts?
Contacts: You must see an eye specialist regarding your vision! PS: At the age of six I went through 5 glasses in 1 year. At age 71 I have worked to get contact lenses and ultimately only glasses. Don't argue with your eye specialist if he or she strongly wants you to wear glasses, not contacts. All should go well! ...Read more
Is it possible to have an allergy to acrylic cataract lenses they put in surgically to correct cataracts?
Probably not: "allergic reactions" do not occur to either silicone or acrylic intraocular lenses. Very rarely people have issues where the lenses need to be removed or exchanged for a different material (silicone for acrylic or vice-a-versa) but this is exceedingly rare. In these situations there are usually other factors in the eye contributing to the need for exchange and not an allergic reaction. ...Read moreSee 1 more doctor answer
Not easily: Scratches in polycarbonate lenses involve the removal of plastic in the scratch. To smooth it out you would need to grind this away which would alter the power of the lense and might induce some distortion. Check with an optical shop to see if some correction is possible or replacement is needed. ...Read more
