Scleral Lens Blog
If you have been diagnosed with keratoconus, you may be aware that traditional soft contact lenses are no longer the best option for you. That’s because the irregular shape of the cornea in people with keratoconus can make it difficult or impossible to achieve an optimal fit with regular soft lenses. The good news is that there are other options – particularly scleral contact lenses. These rigid gas-permeable lenses are larger than traditional lenses and have a unique shape that allows them to fit comfortably over irregular corneas. Here are seven reasons your eye doctor might recommend scleral contact lenses for you.
What Is Astigmatism?
Normally, the front of your cornea curves to fit the surface of your eye. Astigmatism is when one area is flatter than the other. As light tries to pass through the cornea to the retina, the uneven surface of your cornea misdirects it. This causes blurry vision.
The most common symptom of astigmatism is blurry vision. It can be very distracting and debilitating to deal with. Simple tasks like reading a book or being on the computer are a struggle with astigmatism. You may also notice other symptoms like eyestrain, headaches, and eye irritation.
If you’ve had a checkup with your eye doctor, they likely gave you three options for treating astigmatism: prescription glasses, contact lenses, or eye surgery. What they didn’t tell you was that there are natural ways you can treat your astigmatism that won’t cost a penny. Eye exercises and taking vision-boosting vitamins can improve your vision.
Glaucoma is a group of eye disorders that lead to progressive damage to the optic nerve. It is characterized by loss of nerve tissue that results in vision loss. People with glaucoma can lose nerve tissue, resulting in vision loss.
Causes & risk factors
There are many theories about the causes of glaucoma, but the exact cause is unknown. Although the disease is usually associated with an increase in fluid pressure inside the eye, other theories include a lack of adequate blood supply to the nerve.
The following are the different types of glaucoma and their potential causes.
The signs or symptoms of glaucoma can vary depending on the type. Primary open-angle glaucoma often develops slowly and painlessly, with no early warning signs. It can gradually destroy one's vision without even knowing it. The first indication that a person has glaucoma may occur after some vision has been lost. Acute angle-closure glaucoma results from a sudden blockage of drainage channels in the eye, causing a rapid buildup of pressure. In this form of the disease, a patient would have blurred vision, the appearance of halos or colored rings around lights, and pain and redness in the eye.
Glaucoma is diagnosed through a comprehensive eye examination. Because glaucoma is a progressive disease, meaning it worsens over time, a change in the appearance of the optic nerve, a loss of nerve tissue, and a corresponding loss of vision confirm the diagnosis. Some optic nerves may resemble nerves with glaucoma, but the patients may have no other risk factors or signs of glaucoma. These patients should have routine comprehensive exams to monitor any changes.
