Now-a-days there are also "crazy contact lenses" such as cat’s eye. These have many risks of complications. These contact lenses, sometimes called non-corrective lenses, do not correct vision and are intended solely to change the color of the eye, but carry serious risks, including permanent eye injury that may lead to blindness. Occasionally men and women even children use those lenses to get a different look. But it is a valuable concern either you are consulting with an optician or not before using this type of lenses.

The US Food and Drug Administration (FDA) warns consumers about the serious risks of using decorative contact lenses without the appropriate involvement of an eye care professional.

Consumers should only use decorative contact lenses if they have seen an ophthalmologist and have obtained proper lens fitting and instructions for use.

Contact lenses carry the risks of conjunctivitis (inflammation of the conjunctiva better known as pink eye); corneal ulcers; corneal abrasion; and vision impairment or blindness.

Furthermore, sharing of contact lenses prescribed for one person can also lead to infections, abrasions, allergic reaction or blindness.

FDA has received reports of corneal ulcers associated with the wearing of decorative contact lenses, especially when worn overnight.

Corneal ulcers, an infection of the eye, can progress rapidly if left untreated. Uncontrolled infection can lead to corneal scarring and vision impairment. In the most severe cases, this condition can result in blindness and eye loss.

We must consult with eye care professional before using any contact lenses even though it is decorative.
