Lens Thick
In a convex lens the blank of the lens is thicker than the blank?
Help PLEASE!!!!!!!!!!
Convex lenses are thicker in the middle than at the edge.
Concave lenses are thinner in the middle than at the edge (I remember which is which by remembering “cave” – the inner part of the concave lens is like a cave or hole).

Contact Lens Care
People must consider how they will handle their contact lens when they get them home. There are contact lens care systems available that are available that are designed to work well with not only your eyes, but your lenses and lifestyle too. There are different care methods required for soft contact lenses than the care methods for gas permeable lenses.
A contact lens care system will ensure good contact lens care. It is a group of disinfecting and cleaning products that are highly recommended by eye professionals for the type of contact lens that is prescribed for your eyes. Each contact lens prescription is based on your lifestyle which will determine which contact lens is right for you.
Some people mix and match their contact lens solutions because some are cheaper than others, and end up with infected eyes, scratched corneas, and warped contact lens surfaces. For proper contact lens care, solutions in a set system should be used together at all times, and should be used according to the directions on each container.
People should establish a regular contact lens care plan that they will use day by day when they are inserting and removing their contact lenses. A good contact lens care plan would be to meticulous clean your hands by a full wash and drying practice before the lenses are moved from the eyes. For handling contact lenses, a good contact lens care plan would require that the lens be placed in the palm of the hand.
In this position, contact lens care instructions might require squeezing several drops of solution into the palm, and strictly prohibit direct spray onto the contact lens surface. By reading the instructions on the bottle, contact lens wearers will be able to develop a good contact lens care plan.
One contact lens care plan might require that both sides of the lens be rubbed in the solution in a back and forth motion. For other lenses, a manufacturer might institute a contact lens care plant that requires that several drops of cleaning solution be added directly to the lens and rubbed between the forefinger and thumb for 20 to 30 seconds to remove dirt and unseen particles.
Some contact lens care programs require enzyme cleaning solutions to be used to help remove protein deposit from the surfaces of certain brands of contact lenses. A contact lens professional will advise you if this step is necessary to ensure that your vision is not affected by this chemical process.
How you store your contact lens is a major part of a good contact lens care program. Contact lens will not be ruined if they dry out over night, but many people think they are ruined. If a contact lens dries out in the container, all that the contact lens wearer needs to do is perform the cleaning and rinsing process again before they place their contact lens back into their eyes. Simple rewetting is not a good route to take because the solutions penetrate the surface of the lens better than plain water.
