Safety glasses for the workshop

I have a small business making garden furniture out of reclaimed bits of metal in my workshop. I'm also shortsighted. But when you are working in the workshop, it's important that you can see exactly what you are doing, which is why I have been searching for prescription safety glasses. Although my normal glasses are good for most tasks, safety glasses can withstand severe forces without shattering and feels just like wearing my normal glasses. This blog has some different models of safety glasses compared for different workshop conditions, as well as some options for getting yourself fitted for prescription safety glasses.

Keratoconus: Symptoms, Diagnosis And Treatment Approach

by Rachel Alexander

Keratoconus is a progressive eye condition that alters the shape of the cornea, which is the protective clear layer on the front of your eye. The condition causes the cornea to become thinner and thinner and gradually protrude in the shape of a cone. Keratoconus can develop at any age, but it's most often diagnosed in teens and young adults. It tends to affect both eyes, but it doesn't always affect them equally. There's thought to be a genetic component to keratoconus, but it's not yet fully understood why some people develop the condition.

Symptoms Of Keratoconus

The distorted shape of the cornea that's characteristic of keratoconus will cause your vision to become distorted or blurred. It's also common to experience sensitivity to bright lights, which can make your eyes feel strained when driving at night. Vision changes can be sudden, and if you wear glasses, you may find your prescription needs to be altered frequently.

Diagnosing And Treating Keratoconus

Your optometrist can diagnose keratoconus during a routine eye exam. They will use a slit lamp to check the shape of your cornea and carry out an eye refraction test. This involves looking through a phoropter, which is a device that allows you to switch easily between different lenses and can help determine the extent of damage to your vision. In some cases, you may be referred for a corneal tomography. This is a non-invasive diagnostic imaging procedure that measures your cornea and creates a map outlining its shape.

Treatment for this condition is dependent on its severity at the time of diagnosis and aims to slow the progression of the condition and improve your sight. You will require ongoing monitoring to measure the effectiveness of your treatment. Keratoconus that's diagnosed early may initially be treated with corrective lenses. Scleral lenses are often used, as they sit on the sclera, the white part of the eye, rather than the cornea, so they are comfortable for those with keratoconus.

Collagen cross-linking may be recommended if your condition is progressing quickly. This is a relatively new treatment that involves applying riboflavin eye drops to the cornea and then exposing the treated area to ultraviolet light. This treatment stiffens and stabilises the cornea, which prevents further distortion of its shape.

Surgery is often required as keratoconus progresses and your vision deteriorates. The most common type of surgery for this condition is corneal transplant surgery. This is often carried out as a day case procedure and involves either removing the outer layer of the cornea or removing the entire cornea. The replacement cornea is stitched in place and you will be prescribed eye drops to reduce the risk of your immune system rejecting the new cornea. As with any type of surgery, corneal surgery comes with some risks, such as infection and scarring. Discuss the risks with your eye doctor ahead of your surgery appointment.

If you have symptoms associated with keratoconus and require eye surgery, schedule an appointment with your optometrist.
