22mm sclera lenses are a type of special contact lens that covers not only the cornea (the central clear part of the eye), but also a significant part of the sclera (the white part of the eye). These lenses have a larger diameter than standard contact lenses, which usually have a diameter between 14 and 15 mm.

Features of 22mm sclera lenses

1. Wide Coverage : They cover the entire cornea and part of the sclera, making them visible and used to achieve maximum horror and creepy effect.
2. Comfort : Due to their size, they rest on the sclera and not the cornea, which may be more comfortable for some people, especially in cases of corneal irregularities.
3. Aesthetic Uses : Often used in cinema, theater and special effects to create a particular look, such as completely white eyes, black eyes, or with specific designs such as zombies.

Tips for using 22mm sclera lenses

1. Professional Fit : Given their size and specific use, correct eye measurement is critical to avoid complications.
2. Hygiene : Maintaining a high level of hygiene is crucial. Always wash your hands before touching your lenses, and use cleaning and storage solutions recommended by your eye health professional.
3. Wearing Times : Follow your professional's directions on how long it is safe to wear your lenses. It is not advisable to wear them for prolonged periods without breaks as oxygenation of the eye is less with this type of lenses.
4. Monitoring Reactions : Pay attention to any signs of irritation, redness, pain or blurred vision and remove lenses immediately if any problems arise.
5. Replacement and Storage : Sclera lenses must be replaced regularly according to the manufacturer's and professional's instructions. Proper storage of lenses when not in use is essential to prevent infections.
6. Lubrication : The use of lubricating eye drops may be recommended to improve comfort while wearing lenses.

Practical Advice

• Removal and Insertion : Learning the correct technique for inserting and removing lenses is crucial. It can be more difficult than standard contact lenses due to their size, so ask experts for advice and watch specific videos to learn the right technique.
• Regular Visits : Schedule regular visits to your eye doctor to monitor your ocular health and lens fit.

The use of 22mm sclera lenses can offer unique solutions for aesthetic purposes, but requires special attention and constant care to ensure eye health.
