Eye allergies occur when an allergen or something you're allergic to disturbs the membranes of your eye. Several things may irritate your eyes, including pet dander, molds, dust mites, and pollen. Symptoms generally occur in both eyes shortly after exposure to any of these allergens.

Keratoconus is an eye condition in which the cornea bulges outward because it is not able to stay in its normal round shape. This can cause you to have distorted or blurry vision. It can also cause increased sensitivity to glare and light. Severe damage to the cornea’s structure can result in blindness.

Glaucoma is an eye condition that affects the optic nerve. The optic nerve is vital for good vision since it sends signals to all parts of the eye. Glaucoma happens when too much pressure is exerted on the optic nerve. It can affect people of all ages, but mainly it affects people over the age of 60. It happens gradually hence the importance of routine eye checkups. If it is diagnosed early enough, the symptoms can be managed to slow down the progression.

Scleral lenses are not like other contacts on the market. These thin discs of plastics are rigid, gas-permeable (GP) lenses that are noticeably larger in diameter than the usual GP contacts. Unlike conventional contact lenses that are worn directly on the cornea, scleral lenses are designed to rest solely on the sclera. Hence the name. The sclera is the white part of your eye. It has considerably fewer nerve endings compared to the cornea. This means that it’s less sensitive, making scleral lenses much more comfortable to wear.

Fortunately, there’s another option that can help patients to see clearly all day long, without the need to wear glasses or contact lenses – at least while they are awake. It’s known as Ortho-K. 

Nearsightedness or myopia is a growing problem in America. This condition starts in childhood. The child’s eyeballs grow too long, causing a refractive error that causes the child to see only close objects, but those in the distance appear blurry. The lifestyle, family history, or both cause myopia.
