A prescription is considered essential whether you wear contacts for vision correction or for color change. Prescription of contact lenses deals with the strength of the lenses you require depending on the level of your vision impairment, along with the other necessities, for instance; brand of the contact lenses & other fitting measurements. An eye exam prior to contact lens fitting & annual follow-up is recommended by eye experts to prevent CLIDs. Even decorative Halloween lenses require a valid prescription before you freak others out. To find out why, continue reading below:
1. It is misunderstood that a prescription is needed only when you get to correct your vision using contact lenses. Prescription actually is helpful in diagnosing a series of underlying infections that may be dormant now but are subjected to abrupt activation. Only a professional conclusion will be able to classify you as a successful contact lens wearer. Sometimes conditions like dry eyes syndrome, allergic responses & frequent infectious attacks may restrict you from wearing conventional contact lenses. There are special types of contacts available, for each diagnosis but only an eye care professional can help you making a selection.
2. Crazy contact lenses are more or less the same material, regular contacts are made of. Yet, you need to be a bit more vigilant as they are 100% opaque. This discriminates them from conventional contacts. Due to strong dyes being used in manufacturing, these lenses are a bit thicker that make them less permeable. Thus, Halloween contacts should be only worn for 4-5 hours. In case you are visually impaired; you would instead like to try regular contacts with unusual hues to suffice your costume because crazy lenses are not common in prescription.
3. If you are a beginner with no prior knowledge or experience of contact lenses then your first source of learning must be your eye doctor. He demonstrates in depth about contact lens handling, care & storage.
Contacts even if decorative pose no crucial threat, provided they are FDA approved. Talk to your doctor & discuss various available options/brands/ budget before you make your decision. However, keeping in mind that everything has disadvantages that may lead to unpleasant consequences would help consumers staying alert. Be sure you purchase your crazy contact lenses only from the sellers who deal in FDA approved Halloween contacts.
