Contact lenses are popular for its two most important characteristics: flexibility and convenience. Based on their usage, contact lenses are categorized into two types: vision correcting lenses, and decorative lenses. Decorative lenses are used to improve the look of the eyes. Generally, these lenses do not have any corrective power, but some lenses are available that act both as a decorative piece and as a vision correcting lens. Decorative contact lenses are known as fashion contact lenses, colored contacts, or halloween contacts. Contrary to common belief, these lenses are not over-the-counter products or a cosmetic. These products are considered medical devices, and fall under FDA regulations like drugs.
Any contact lens has some amount of risk with its usage. Colored contact lenses without a prescription might be ill-fitting, which may lead to serious eye damage.
Some of the common issues with ill-fitting contact lenses are:
- Scratches on the cornea
- Infection of the cornea
- Reduced vision
Allergies are also very common with different contact lens products. These damages are associated with any kind of contact lenses, particularly when used without a prescription and follow-up care. These risks are occur more for colored contacts because most of the people who use them do it without the initial check-up by a qualified professional. So, avoid getting colored contact lessons from salons, street vendors, or flea markets. One should never share contact lenses with another person. Most of all, always buy colored contacts from a retailer who asks for a prescription. The same applies while buying lens online. Opt for sites that ask for a prescription while choosing the product.
Wearing a contact lens is like introducing a foreign object to the body. One can make colored contacts safe by getting his or her eyes checked by a licensed practitioner. Always use a valid prescription for buying a decorative lens. The prescription should contain lens measurements and an expiration date. These lenses should also be cleaned and disinfected before use. This will help to prevent infection. One should consult with a doctor immediately if there are any symptoms of an eye infection. This includes redness, eye pain, or a decrease in vision.
