Why does Bono always wear those weird glasses?

Consequently, it is a good habit for contact lens wearers to spend a few hours a day wearing glasses instead of contact lenses. This allows their eyes to recover from any lack of oxygen they might have experienced. People who wear contact lenses increase their risk of eye complications.

These problems may be caused by many factors including bacteria, viruses, fungus, amoebas, allergies, or the contact lens itself. When an eye is infected, it is often beneficial to discontinue the use of contact lenses until the eye heals. During this time, people without glasses are often put in a difficult position: Do they put their eyes at risk by continuing to wear contacts?

Or, do they suffer through poor vision until they receive a pair of glasses? By having a pair of backup glasses ready to go, this difficult decision can be avoided. Many people enjoy activities that are not conducive to comfortable contact lens wear.

For example, campers may find it a hassle to clean and remove their contact lenses at night. Or, a day at a sandy beach may be better spent in glasses to avoid the painful, gritty sensation that occurs when sand enters an eye containing a contact lens. These patients would benefit from wearing glasses instead of contact lenses.

Some people work in environments where their eyes are at risk for injury. Although safety glasses are absolutely the best way to protect their eyes, wearing normal glasses does provide more protection than contact lenses alone. Glasses may be a convenient compromise for those unwilling or unable to wear proper safety glasses.

Contact lens wearers can benefit from owning a pair of glasses in many ways. First, wearing glasses increases the amount of oxygen reaching the eyes. Also, glasses may be worn during eye infections when contact lenses are contraindicated.

Glasses may also provide lifestyle benefits, rudimentary eye protection and make a fashion statement. Glasses are very stylish. They can accentuate or pull attention away from attractive or unattractive facial features.

A good pair of glasses can help people look their very best.
