There is an ever-increasing demand for contact lenses ever since they were invented, as they not only improve a person’s vision, but also add to the style. Available in a variety of colors and options, contact lenses are preferred by many over the regular eye glasses. While buying a new pair of contact lenses, you must see an eye-care professional and get the prescription for contact lenses after thorough eye checkup. Other things to consider are the color, style and type of contact lenses.
There are basically two main types of contact lenses – soft and hard contact lenses. Let’s see how hard contact lenses are different from soft contact lenses. They vary in many aspects. Few of them are discussed below:
- Material: The foremost difference between hard and soft contact lenses is based on the material that is used to create them. Initially hard contact lenses were made of glass, but now, semi-rigid gas permeable, which is a sort of plastic, is used to make them. These lenses are made to adjust to the cornea of the wearer’s eye. Whereas, the soft lenses are constructed out of a very flexible plastic and can also be turned inside out. If these lenses are worn inside out, they may harm the eyes of the wearer.
- Durability: The hard lenses are much durable than soft lenses because they do not tear off easily as soft lenses. Common impurities like soaps, lotions etc. are not easily blotted by hard lenses even if they come in contact with wearer’s eyes. The soft lenses on the other hand, absorb these impurities very easily. This leads to a buildup and the lens becomes ineffective eventually. This problem is resolved only by replacing the lens. Soft lenses can also cut easily and therefore, require to be handled very gently and carefully.
- Vision Correction: Although, both of the lenses are great for vision correction, hard contact lenses are considered to be much better for the job. These lenses are made to fit the eye of an individual and therefore, it also controls the growth of nearsightedness. Soft lenses, can correct other vision problems like farsightedness, and astigmatism, besides nearsightedness.
- Comfort: The wearer of hard contact lenses often complains about being uncomfortable after wearing the lens. A breaking in period is also required for wearing hard lenses. This process has to be repeated if the lenses are not worn regularly. Soft lenses are easily molded to fit the wearer’s eye so that the wearer can easily get use to wearing lenses. Moreover, the high water content of these lenses makes them more comfortable for the eyes.

Our eyes are very sensitive and need special protection and care from the harmful rays or dirt. It is important to do proper eye exercising, along with regular check up ensures the longetivity of the eye vision.
The middle part of the eyes, called the uvea or the uveal tract, mainly comprise of three parts
- Iris is the colored part of the eye which acts as a diaphragm and controls the amount of light that enters the eyes. It lies between the cornea and the lens.
- Ciliary body is that part of the eye which lies between iris and choroid. It holds the lens and accommodates the water/tear production.
- Choroid are the layers of blood vessels that are located between the sclera and the retina of the eye. They provide blood supply to the retina.
What is Uveitis?
Uveitis is referred to inflammation of the uvea or the uveal tract of the eye. The uvea is responsible for the transportation of the blood through veins and arteries, which is very important for the eye vision.
There are mainly four types of Uveitis, depending on the specific part of the uveal tract being affected. These types are:
- Anterior Uveitis: It is also known as Iritis. In this type of Uvetis, inflammation of iris takes place.
- Intermediate Uveitis: It is also known as cyclitis. In this type the ciliary body of the uveal tract suffers inflammation. It also may affect the muscle that focuses the lens.
- Posterior Uveitis: It is also known as choroiditis as the inflammation of the choroid of the uvea takes place.
- Diffuse Uveitis: It is the inflammation of retina and swelling happens in most of the areas of uvea. It is also known as retinitis or panuveitis.
Uveitis and its various forms can be caused due to many reasons. It may be caused from a viral infection or the infection from fungus, bacteria or parasite. It usually happens to the middle-aged people, but small children are also easily infected. If your eyes are light sensitive and suffer from eye pain or irritation, get your eyes checked urgently. Eye floaters or blurred vision is also symptom of Uveitis.

Retinoschisis can be termed as an eye disease which can be characterized by abnormal splitting of the retina's neurosensory layers. If left unattended it can result in vision loss. Though Retinoschisis can be termed as a form of macular degeneration, it can be further divided into four types.
- Degenerative Retinoschisis – Though it is not a genetically inherited condition, Degenerative Retinoschisis is often confused with Retinal Detachment and should be attended by an expert eye doctor. It has been found in upto 7% of normal human beings.
- Hereditary Retinoschisis - This is a less common disease and is believed to occur one in every 5,000 to 25,000 individuals. As the name suggests it is an inherited disease often inherited by men from their unaffected carrier mothers. It is believed to be caused by an X-linked genetic defect, affecting the vision of men. However, very few men are said to go blind due to this disease. Hereditary Retinoschisis causes tiny cysts in the retina which can be detected by an expert.
- Tractional Retinoschisis - This disease is said to cause traction on the retina especially at the macula.
- Exudative Retinoschisis – It affects the central part of retina, secondary to optic disc pit. Exudative Retinoschisis is believed to cause substantial vision loss. Treatments like Laser Photocoagulations, Vitrectomy and Gas Injection are believed to be effective in this form of Retinoschisis.
Genetic birth defect is the only known cause of Retinoschisis.
- Decreased vision
- Loss of peripheral vision
- Division of retina
- Vision defect
- Occurring disintegration of retina
- Inability to see clearly in bright light.
- Someone who is nearsighted or farsighted can use spectacles to improve the overall quality of vision however this cannot repair the nerve tissue damage.
- Even though Vitamin A is quite helpful in case of genetic retinal diseases but it has little effect on retinoschisis.
