Astigmatism is linked to distorted and hazy eyesight. It generally occurs due to an imperfection in the eye’s curvature. Corrective contact lenses are a viable option to improve the vision in such cases. People can consider several types to determine which will provide the greatest vision correction. Toric, gas permeable, and hybrid lenses are the three well-known kinds of contact lenses for astigmatism.

Individuals often start experiencing deterioration in vision as they age. This gradual loss of vision in people hampers their close-range vision. This condition is common in people in their mid-40s and is known as presbyopia. To correct such loss of vision, doctors may recommend either bifocal or multifocal contact lenses.

Multifocal contact lenses are designed to allow multiple prescriptions into one lens design. These lenses are mainly for those dealing with presbyopia, a condition that causes age-related vision issues. In this disorder, the eyes cannot focus on varying objects at different distances. A multifocal lens helps adjust this problem. However, there are many crucial factors to consider before buying multifocal contact lenses.

Meningitis is an infection caused by bacteria that affects the membranes surrounding the brain and spinal cord. It can be caused by a number of different bacteria and may show symptoms like high fever, seizures, and headaches. Certain factors can increase one’s risk of developing this condition. Understanding these factors can help one protect themselves from contracting the disease.

Meningitis B leads to inflammation of the liquid that lines the spinal cord and brain. It occurs due to an infection caused by the Neisseria meningitidis bacteria and can lead to dizziness, poor appetite, and a flu-like condition. As people can get sick quickly after contact with an infected person’s saliva, it is important to know symptoms and act when they appear to oneself or others.

Deteriorating vision is a common problem as a person ages. Doctors typically recommend multifocal contact lenses for those with myopia (nearsightedness), astigmatism, hyperopia (farsightedness), or presbyopia (age-related farsightedness). These lenses allow one to see better and are far more comfortable than contacts or reading glasses. However, they are not for everyone.

Neurofibromatoses are a group of genetic disorders that cause tumors in the nervous system. There are three types of neurofibromatosis: mainly neurofibromatosis 1 (NF1), neurofibromatosis 2 (NF2), and schwannomatosis. The symptoms are usually mild but may cause serious complications. Here are the common symptoms of neurofibromatosis and what causes them.

A rotavirus infection triggers diarrhea and vomiting in children. In fact, before the vaccine for this virus was developed, most children would be affected at least once by the age of 5. Doctors usually recommend giving children rehydration fluids to replenish all the water lost due to diarrhea. Other than that, there are no major treatments unless the infection triggers health complications linked to rotavirus.
